Executive Summary
Under Section 14(1) of the Sydney Water Catchment Management Act 1999 a principal objective of
the SCA is ‘to ensure that water supplied complies with appropriate standards of water quality’. The
SCA Water Monitoring Program 2010-2015 (WMP) details a comprehensive and integrated
monitoring plan covering catchments, reservoirs, intakes to water filtration plants, picnic area sites
and downstream sites. The WMP has been developed in collaboration with NSW Health, Sydney
Water and other wholesale customers. The program, endorsed by NSW Health, incorporates
locations, frequency, benchmarks or guideline values for more than 200 characteristics. The WMP
involves routine, event, algal, pathogen and hydrometric monitoring; employing field, laboratory and
telemetered ‘real-time’ sampling. The WMP provides timely water quality data and information to
inform operational decisions.
The Australian Drinking Water Guidelines’ framework for the management of water supplies covers
the whole supply chain from source to the consumer to ensure safe drinking water. The SCA is
responsible for managing part of this supply chain (catchments, storages and raw water supply
system) working closely with upstream stakeholders through to downstream customers so as to
ensure the raw water supplied for treatment is of appropriate quality. Raw water is treated by the
customers who report on drinking water quality. Monitoring of the water quality through this supply
chain provides essential information with regards to the short and long term water quality risks.
This report describes the results of the water quality monitoring undertaken by the SCA during 201314. The report is provided to meet the SCA’s statutory obligations in addition to providing
stakeholders, students, researchers and the general public with water quality information for waters
managed by the SCA.
Highlights
Guided by the SCA Water Quality Management Framework, the SCA successfully delivered agreed
quantities and quality water to customers in full compliance with the Australian Drinking Water
Guidelines (ADWG) for health related characteristics. Through proactive source selection, modelling
and online monitoring, the SCA avoided or effectively managed water quality incidents to minimise
impacts to customers.
The 2013-2014 reporting period commenced with many storages operating at full capacity, with total
storage volume at 98% on July 1, 2013. Below average inflows and no significant transfers over the
reporting period caused total storage volume to fall to 82% by June 30, 2014.
Water supplied to water filtration plants maintained very high compliance with raw water supply
agreements. Source selection and system planning minimised the impact of elevated true colour on
filtration plants supplied by Lake Burragorang and Nepean. Heavy metals, pesticides and synthetic
organic compounds remained well below ADWG at all water filtration plant sites with very few
detections.

The SCA monitored for E. coli in picnic area supply as a further confirmation of the effectiveness of
disinfection as it was difficult to maintain chlorine residual. The monitoring regime and guidelines will
be revised from July 2014 in accordance with the NSW Private Water Supply Guidelines.
Consistent with recent years, nutrients (nitrogen and phosphorus) and chlorophyll-a regularly
exceeded ANZECC benchmarks in catchment sites with significant agricultural or urban development
(e.g. Wollondilly and Kangaroo Rivers). In contrast, natural catchments (e.g. Burke and Cataract
Rivers) rarely exceeded ANZECC benchmarks and continue to demonstrate the effectiveness of
Special Areas in protecting water quality.
Following inflows in June 2013, high concentrations of nutrients nitrogen and phosphorus were
observed in a number of storages, lakes Burragorang and Yarrunga particularly. Despite the elevated
nutrients, algal activity in 2013 was moderate with normal concentrations of chlorophyll-a and no
algal toxins detected. Chlorophyll-a concentrations in Blue Mountains storages were significantly
higher than previous years. Further analysis identified the non-toxic diatom Urosolenia as the
dominant species.
Water quality conformance for 2013-14 with regards to
Raw Water Supply Agreements and Australian Drinking Water Guidelines
was 99.94% and 100% respectively.
Monitoring downstream of SCA storages is undertaken as part of the requirements of the Water
Licences and Approvals package issued by the NSW Office of Water. The impact of pollutant sources
downstream of SCA storages is evidenced by the deterioration of water quality downstream of SCA
release points, particularly in the Hawkesbury – Nepean system. While nitrogen and chlorophyll-a
regularly exceeded ANZECC benchmarks, potentially toxic algae remained below levels that pose any
risk to recreational users.
Guided by the Science Strategic Plan, the SCA has continued to initiate a number of scientific
research projects through internal and external collaborative arrangements. Notable research
projects with a direct influence on water quality management included:
 effect of chlorination on Giardia in the Upper Canal
 sources of taste and odour producing compounds in Prospect Reservoir
 risk assessment of pesticides and synthetic organic compounds
 characterising catchment risk of pathogens
 sources and causes of colour in raw water
The SCA successfully managed two water quality incidents in accordance with the Raw Water
Quality Incident Response Plan in the reporting period:
 elevated algae areal standard units in Kangaroo Valley raw water
 elevated algae areal standard units in Prospect raw water
In March, 2014, heavy storms over the bushfire impacted Upper Nepean Catchments led to variable
water quality in the Broughtons Pass Weir pool. As a result, supplies to the Macarthur Water
Sydney Catchment Authority Annual Water Quality Monitoring Report 2013-14

Filtration Plant and the Upper Canal were affected. Macarthur WFP was temporarily shut down while
Upper Canal water was diverted to Prospect Reservoir. Sydney Water and NSW Health were satisfied
with the SCA’s response to the incident.
During 2013-2014 the SCA revised the WMP to incorporate changes in the Australian Drinking Water
Guidelines. The program was endorsed by NSW Health and will be implemented from 1 July 2014.

1 Introduction
Section 14(1) of the Sydney Water Catchment Management Act 1998 (the Act) states that a principal
objective of the SCA is ‘to ensure that water supplied by it complies with appropriate standards of
water quality’. The SCA undertakes extensive monitoring within its catchments, storages and raw
water supply system and in rivers downstream of storages to meet this objective.
The SCA’s Water Monitoring Program 2010–2015 sets out the location, frequency and analytes
monitored. Specific and health-related characteristics are determined in consultation with our major
customers and the program is endorsed by NSW Health. Monitoring for operations and planning
helps the SCA understand the threats to water quality throughout the supply system, including rivers,
reservoirs and the delivery system. This information aids the selection of the best source water for
our customers and the environment.
The SCA’s Water Monitoring Program is informed by pollution source assessment for the four priority
pollutants of pathogens, nutrients (phosphorus and nitrogen) and suspended solids. Catchment-totap water quality risk assessments are also undertaken for each supply system in conjunction with
NSW Health and customers, and inform the Program to a large extent. The outcomes of risk
assessments assist in prioritising monitoring as well as actions to rectify existing threats to water
quality within drinking water catchments.
Data collected through the Water Monitoring Program is used to:
• provide early detection of possible contaminants in raw water to help protect the health of
more than four million consumers
• to assist in proactive operational decisions
• ensure that the raw water delivered to SCA’s wholesale customers meets agreed standards
and can be treated to meet the Australian Drinking Water Guidelines
• identify and target possible contamination sources in the catchments and storages
• identify emerging water quality issues and address them in forward planning
The SCA’s compliance monitoring activities are governed by four key drivers:
 operating licence granted by the Governor of NSW and administered by Independent Pricing
and Regulatory Tribunal (IPART)
 Water Licences and Approvals package granted by the Water Administration Ministerial
Corporation and administered by the NSW Office of Water (NOW)
 raw water supply agreements between the SCA and its wholesale customers
 Australian Drinking Water Guidelines

2 Overview of the water supply network
The SCA collects water from river catchments to the south and west of Sydney and stores it in lakes
and reservoirs to supply more than four million people in the Greater Sydney region.
It is transported via a network of rivers, pipes and canals to water filtration plants, where it is treated
for consumers in Sydney, Illawarra, the Shoalhaven, Goulburn, Blue Mountains and the Southern
Highlands. Water is also released from storages as environmental flows to maintain the health of the
downstream river systems.
The catchments cover an area of approximately 16,000 square kilometres (sq km) — extending from
the headwaters of the Coxs River north of Lithgow, south to the source of the Shoalhaven River near
Cooma, and from Woronora in the east to the source of the Wollondilly River near Crookwell in the
west (Figure 0.1).
Raw water is collected from the river systems of five major catchments:
 Warragamba
 Upper Nepean
 Woronora
 Shoalhaven
 Blue Mountains.
The characteristics of each system are summarised in Table 2.1, including the supply zone and
storage capacities. The transfer routes for water around the system and approximate number of
people supplied by that part of the system are shown in the schematic water supply system (Figure
2.1). Water is also sourced from the Fish River to supplement Blue Mountains supply.
The Australian Drinking Water Guidelines framework for management of water supplies covers the
whole supply chain from source to the consumer to ensure safe drinking water. The SCA is
responsible for managing part of this supply chain (catchment, storages and raw water supply
system) but recognises the importance of this approach and works closely with upstream
stakeholders and downstream customers to ensure raw water supplied for treatment is of
appropriate quality. Raw water is treated by the customers who report on drinking water quality.

The total capacity of a reservoir is the amount of water it can hold when full. Operational restrictions may reduce the amount of
useable water (Operating Capacity) that the SCA can supply to its customers.
2.1 Warragamba system
The Warragamba delivery system consists of two large diameter pipes which transport water by
gravity from Lake Burragorang to water filtration plants (WFP) at Warragamba, Orchard Hills and
Prospect. Prospect Reservoir can supply directly to Prospect WFP. Water from the Upper Nepean
system is also supplied to Prospect via the Upper Canal.
Lake Burragorang, which sits behind Warragamba Dam, is the SCA’s largest reservoir with the
capacity to supply up to 80% of Sydney’s water. One quarter of the catchment is a declared Special
Area, where public access is restricted to protect water quality, the land here is mostly natural
bushland. The rest of the catchment has eight local council areas with several different types of land
use.
2.2
Upper Nepean system
The Upper Nepean system is fed by four dams - Nepean, Avon, Cordeaux and Cataract. These dams
collect water from rivers on the Illawarra Plateau to supply water to Sydney through Broughtons Pass
Weir and the Upper Canal. The Macarthur WFP supplies drinking water sourced from the head of the
Upper Canal delivery system at Broughtons Pass Weir to the Camden, Campbelltown and Wollondilly
local government areas.
Sydney Catchment Authority Annual Water Quality Monitoring Report 2013-14
16
The Nepean catchment is mostly natural bushland with some grazing and cropping in the upper
Nepean River catchment. Forestry, intensive agriculture and mining also occur within this catchment.
The Nepean WFP supplies drinking water to the surrounding rural area and the local townships of
Bargo, Thirlmere, Picton and The Oaks.
Lake Avon supplies the Illawarra region and comprises mostly highly protected bushland. Water is
transported from the upper reaches of Lake Avon by gravity or by pumping to the Illawarra WFP for
supply to the Illawarra region. Water from Lake Nepean can also be transferred via a tunnel to Avon
Dam to supplement supply to the Illawarra region.
Cordeaux and Cataract catchments are mostly Special Areas, containing largely unspoilt bushland.
2.3 Woronora system
The Woronora system delivers water via a pipe system from Lake Woronora to Woronora WFP,
which supplies approximately 100,000 residents of Helensburgh, Engadine and parts of Sutherland
Shire. Lake Woronora is located on the southern outskirts of Sydney on the western side of
Heathcote National Park.
2.4 Blue Mountains system
The Blue Mountains delivery system is a complex system that can deliver water from both within and
outside the Blue Mountains bushland catchments.
The system provides water to residents of the middle and upper Blue Mountains from Lake Greaves,
Lake Medlow and the three Cascade lakes at Katoomba (five of the smallest reservoirs managed by
the SCA).
All five lakes contribute to the supply of water to the Cascade WFP, which can also be supplemented
with water transferred from Lake Oberon on the Fish River or from the Duckmaloi River at Duckmaloi
Weir (both west of the Great Dividing Range).
Water from Warragamba Dam (treated at the Orchard Hills WFP) is pumped up the mountains to
supplement the system, supplying water to residents of the lower to middle Blue Mountains.
2.5 Shoalhaven system
The Shoalhaven system is a network of dams, pumps, canals and pipelines that transfers water from
the catchments of the Shoalhaven River via Wingecarribee Reservoir to either the Warragamba or
the Upper Nepean systems to supply Sydney and the Illawarra region during times of drought.
Wingecarribee Reservoir supplies water to Wingecarribee WFP, operated by Wingecarribee Shire
Council to supply drinking water for consumers in the Southern Highlands. Wingecarribee Reservoir
can also transfer raw water to Goulburn Mulwaree Council to supplement storage levels in Goulburn
Mulwaree’s water supply dams if required.
The system is also used by Origin Energy to generate electricity. Power generation involves the
regular exchange of stored waters between Lake Yarrunga, Bendeela Pondage and Fitzroy Falls
Sydney Catchment Authority Annual Water Quality Monitoring Report 2013-14
17
Reservoir. Bendeela Pondage is a very small impoundment in the delivery system between Lake
Yarrunga and Fitzroy Falls Reservoir. Raw water from Bendeela Pondage is treated at the Kangaroo
Valley WFP operated by Shoalhaven City Council to supply drinking water for the residents of
Kangaroo Valley.
The SCA releases water from Lake Yarrunga downstream into the Shoalhaven River for the
Shoalhaven City Council to supply its customers.
The major storage is Lake Yarrunga, at the junction of the Kangaroo and Shoalhaven Rivers. The
catchment has a variety of land uses, including bushland, dairy farming, beef and sheep production,
and rural residential.
2.6 Hawkesbury-Nepean River
The Hawkesbury–Nepean River sits below the major storage reservoirs in the Warragamba and
Nepean catchments. It is sustained by:
 flows from local catchments
 spills from the SCA storages
 environmental flow and other releases from the SCA storages which help maintain and
improve the ecological health of the river
 flows of treated effluent from Sydney Water’s waste water and recycled water treatment
plants.
The NSW Office of Water licenses various water extractors along the length of the Hawkesbury–
Nepean River for agricultural and some industrial use. Sydney Water also draws and treats water
from the river at North Richmond to supply consumers in that area.

3 SCA’s water monitoring program
The SCA’s Water Monitoring Program 2010-2015 (WMP) covers routine, targeted, investigative and
event-based monitoring over its area of operations.
The WMP covers catchments, storages, inlets to water filtration plants, picnic taps, transfer canals
and pipelines, as well as rivers downstream of water supply dams and weirs. Monitoring includes
physical, chemical, biological, radiological, hydrological and meteorological parameters through online instruments, field sampling and laboratory analysis. A key feature of the WMP is an agreed list of
water quality characteristics. The list contains:
 those characteristics that cannot be modified or removed by conventional treatment and for
which Australian Drinking Water Guidelines (ADWG) must be met
 those characteristics for which ADWG exist but are not applicable to raw water, where the
SCA must endeavour to supply raw water so that it can be treated to meet the ADWG.
The SCA is subject to a range of statutory requirements and standards set by regulatory agencies. The
SCA is also benchmarked against other raw water suppliers to maintain best practice service
standards.
The principal documents that outline requirements on the SCA with respect to water monitoring are:
 SCA Operating Licence, Sydney Water Catchment Management Act 1998 (Part 4)
 SCA’s Water Licences and Approvals Package under Water Management Act 2000
(Chapter 3) - referred to as Water Licences in the rest of this document
 Memorandum of Understanding (MoU) between NSW Health and the SCA (Parts 5-7) Sydney
Water Catchment Management Act 1998 (Part 4)
 Raw Water Supply Arrangements, Sydney Water Catchment Management Act 1998 (Part 3)
 Water Act 2007 (C’th).
3.1 Quality assurance and quality control
The SCA’s Water Monitoring Program 2010–2015 specifies the requirements for water sample
collection and analysis. It describes sampling locations and frequencies, and the parameters to be
analysed. Additional samples are collected and analysed for quality assurance and quality control
(QA/QC) purposes. The QA/QC program provides confidence in the routine sampling data collected.
Water quality data integrity is assured through the design of the routine and QA/QC sampling
regimes and the analysis tools used to review data once it is delivered to SCA. The primary goal of
field collected QA/QC samples is to identify, quantify and document bias and variability in data that
result from the collection, processing and handling of samples. This process also assists in identifying
opportunities to improve sampling methodologies. This is particularly important when sampling for
parameters that are likely to be present at very low concentrations (due to measurement
uncertainty).
Sydney Catchment Authority Annual Water Quality Monitoring Report 2013-14
19
Field collected QA/QC samples include field duplicates and field blanks. Trip blanks are also prepared
and taken on designated sampling trips.
The SCA’s analytical service providers have management systems that require them to maintain their
own internal QA/QC program. These systems are accredited with the National Association of Testing
Authorities (NATA) and ISO 17025. The analytical service providers conduct internal quality control
analysis per each batch of samples including matrix spikes, duplicates, blanks, replicate analysis and
inter laboratory proficiency trials. The service providers’ QA/QC specialists analyse conformance with
specified standards of accuracy and precision to identify any contamination, outliers or errors.
The collection and analysis of routine and QA/QC water samples is performed by SCA service
providers. Service providers are contracted to include requirements for quality assurance practices in
the monitoring, sampling, testing and reporting processes. A chain of custody system allows
individual samples to be tracked from field collection, through laboratory analysis, to the transfer of
results to the SCA’s database.
Further details of the QA/QC monitoring for 2013-14 are included in Section 5.1.
3.2 Operating Licence
The Operating Licence requires the SCA to:
 Maintain a water quality management system consistent with the framework for managing
water quality as outlined in the ADWG.
 Maintain a water quality monitoring program (comprising routine monitoring of raw water)
to the satisfaction of NSW Health.

Conduct a targeted, investigative and event based monitoring program to monitor the
occurrence of particular characteristics and contaminants in water.

Submit a report to IPART and NSW Health each financial year summarising the monitoring
program and performance against applicable guidelines.
The ADWG framework recommends monitoring for verification of water quality with short term
evaluation of results to enable incident response and corrective action. The ADWG framework also
recommends investigative and research monitoring and long term evaluation of results for continual
improvement.
Routine water monitoring provides information for compliance and operational decision-making.
Monitoring in catchments and storages is used to provide early warning of any risks, while
monitoring at the inlet of treatment plants is used to verify the effectiveness of controls.
Routine monitoring is supplemented by event and investigative monitoring targeting specific issues
or knowledge gaps or to assess the effectiveness of management strategies, investigations into
incidents or events or research to build knowledge of the water supply system. The outcomes of
specific non-routine monitoring projects are also used to inform the review of routine monitoring.
Sydney Catchment Authority Annual Water Quality Monitoring Report 2013-14
20
3.2.1
Raw water supplied for treatment
Raw water is monitored in the delivery system and at inlets to WFPs prior to the water treatment
process. This helps verify that water quality meets the agreed criteria and ADWG for health related
characteristics.
3.2.2
Storages
The SCA’s storages are monitored at various sites and depths to provide detailed information on lake
conditions and processes. Monitoring is supported by modelling that assists in assessing current
conditions and predicting possible changes. Profiling of storages (i.e. measuring parameters at
discrete depths) is undertaken routinely to assist in selecting optimal supply depth to prevent
hazards entering the water supply.
3.2.3
Catchments
Routine sampling of catchment streams enables the quality of catchment waters to be assessed and
any contamination identified. This allows water quality hazards to be managed within an adaptive
management framework. Routine hydrometric monitoring measures rainfall and inflows to storages
to help predict major inflow events, flooding and any associated water quality risks.
3.2.4
Picnic area monitoring
The SCA supplies chlorinated water to picnic areas at Fitzroy Falls Reservoir (including the National
Parks and Wildlife Service’s visitor centre), Cataract, Cordeaux and Avon dams. In 2014, the SCA
developed and implemented a Drinking Water Quality Management Plan for Picnic Areas in line with
NSW guidelines that include the required monitoring for individual supply areas.
3.2.5
Algal monitoring
The SCA routinely monitors algae in major storages to provide early warning of possible bloom
conditions. This ensures that raw water supplied to customers can be treated to meet drinking water
guidelines. It also helps avoid the contamination of downstream waterways through environmental
releases or transfers. A seasonal sampling program (usually conducted between October and May)
applies in storages with a history of algal activity. Monitoring frequency is increased in response to
triggers specified in the SCA’s Cyanobacteria Response Plan.
3.2.6
Cryptosporidium and Giardia monitoring
A consolidated monitoring program for Cryptosporidium and Giardia was implemented in April 2001,
following an agreement between the Ministers of NSW Health, Sydney Water and the SCA. This
program remained in place for 2013–14.
Sydney Catchment Authority Annual Water Quality Monitoring Report 2013-14
21
3.2.7
Wet weather monitoring
Wet weather samples provide information on pollutants associated with rain events or large inflows.
The collection and analysis of wet weather water samples across the SCA’s catchments is essential in
identifying potential pollution sources. The SCA has installed autosamplers at strategic locations in
the catchment, which are triggered by changes in river levels.
3.2.8
Dam seepage
The SCA is required to monitor the structural integrity of prescribed dams, including seepage in,
around and through its structures. Dam seepage monitoring is undertaken to comply with Dam
Safety Act 1978.
3.2.9
Downstream of storages
A number of sites downstream of SCA storages are routinely monitored in accordance with Water
Licence requirements. Sites are maintained as per an agreement with NSW Office of Environment
and Heritage and included in the triennial audits of the Sydney’s drinking water catchments.
3.3 Water Licences
In May 2012, the NSW Office of Water issued the SCA a new Water Licences and Approvals Package
under the Water Management Act 2000, which is a combination of ‘Water Access Licences’ and
‘Water Supply Work and Water Use Approvals’. The Water Licences require environmental flows to
be released from reservoirs to help maintain the ecological health of downstream rivers. Water
released from reservoirs into rivers can be colder or warmer than the receiving water depending on
the level of the water offtake in the reservoir (deeper water is usually colder than surface water) and
the time of the year. The SCA undertakes temperature and routine water quality monitoring at a
number of downstream sites to assess impacts of SCA operations on downstream river systems.
3.4 Future directions
In 2013-14, a full review of the Water Monitoring Program was undertaken to determine the water
monitoring requirement for 2015-20. This review was to incorporate changes to the ADWG and the
Public Health Act 2010. Both the routine program and the investigative component of the water
monitoring program were revised. The revised program was endorsed by NSW Health and captured a
number of key changes and future directions including:
 Updated monitoring program for SCA managed picnic areas
 Incorporation of static vertical profilers at three new sites in Lake Burragorang and one site in
Lake Nepean
 Continued roll out of the wet weather autosampler program
 Addition of a targeted campaign monitoring program for Cryptosporidium during wet
weather events

Picnic taps
Amendments to the NSW Public Health Act (2010) and Public Health Regulation (2012) required
suppliers of drinking water to have a Quality Assurance Program approved by NSW Health in place by
1 September 2014. While most of the water supplied by SCA is raw water that is treated by our
customers, water supplied by SCA at picnic areas is for public consumption. As part of the Drinking
Water Management Plan and associated Quality Assurance Plans put in place for drinking water
supplied at Avon, Cataract, Cordeaux and Fitzroy Falls picnic areas, changes were made to how we
monitor water quality at picnic taps. These changes were guided by NSW Health and the NSW Private
Water Supply Guidelines which came into effect in March 2014. These changes were implemented in
July 2014 with the commencement of the revised Water Monitoring Program. As such, data
presented in this report conforms to the 2010-2015 Water Monitoring Program.
3.4.2
Vertical profilers
A vertical water quality profiler installed 500 metres upstream of the dam wall in Lake Burragorang in
2012 has provided highly resolved temporal (every 3 hours) data on temperature, pH, conductivity,
turbidity and dissolved oxygen. The data has been very useful in improving our understanding of
water quality processes such as stratification/de-stratification and wet weather intrusion events. The
data was used to make proactive operational changes and avoid pollutants entering raw water
supply. Following the success of this instrument, four new profilers were commissioned in 2014 – an
additional three in Lake Burragorang and the fourth in Lake Nepean. The newly installed profilers in
Lake Burragorang are located further upstream near the junction of the Wollondilly and Coxs arms
and in each arm of the lake. The positions of the new profilers were selected to improve our early
warning systems for water quality impacts from inflows and intrusions. A fifth profiler is planned to
be installed in Lake Woronora.
3.4.3
Autosamplers
In 2013-14 a number of new monitoring sites were installed in the catchment as part of an effort to
increase risk-based monitoring in those areas. These sites were selected based on the risk profiles of
individual drainage units in the catchment for elevated phosphorus, nitrogen, suspended solids
and/or pathogens. This assessment was undertaken using SCA’s GIS-based Pollution Source
Assessment Tool. The sites are equipped with telemetered level gauges which trigger autosamplers
to capture high flow samples during wet weather events. This program will continue to be rolled out
in 2014-15 with the aim to better understand water quality in vulnerable catchment areas and
inform catchment actions.
Sydney Catchment Authority Annual Water Quality Monitoring Report 2013-14

3.4.4
Campaign monitoring
A plan has been drafted by the SCA’s Science team for a targeted monitoring program to assess the
real risk of Cryptosporidium and Giardia during wet weather events affecting Lake Burragorang and
Lake Nepean. This program has been flagged in the Water Monitoring Program2015-2020. The aim of
the campaign monitoring is to ensure targeted collection of samples during wet weather events to
quantify Cryptosporidium and Giardia risk into and through our lakes during large inflows. Any
Cryptosporidium detected will also be assessed for infectivity status and speciated to understand
zoonotic potential, i.e. ability to infect humans. The data from this monitoring will inform SCA’s
Quantitative Microbial Risk Assessment.
3.4.5
Healthy Catchments Strategy projects
As part of the Healthy Catchment Strategy, SCA endeavours to reduce the risk of potentially high risk
pollution sources such as sewage treatment plants, householder managed onsite sewage systems,
stormwater runoff and intensive livestock management. As part of this process, investigative
monitoring programs have been established to monitor how effective our interventions are at
reducing nutrients and/or pathogens entering local waterways. Through the Priority Pollution
Program component of the Healthy Catchment Strategy, SCA has given out infrastructure grants to a
number of councils in the local catchment to undertake improvement projects. Three of these
projects have collaborative investigative monitoring projects to provide SCA with the real water
quality benefits of different intervention strategies being undertaken in regard to:
 Sewer line extension for the decommissioning of individual onsite sewage systems,
 Installation of water sensitive urban design stormwater infrastructure,
 Sewage treatment plant upgrade to sufficiently mitigate the transfer from land-based
effluent disposal to stream based disposal.
3.4.6
Pesticides and SOCs
In 2012-13, a collaborative (NSW DPI, SWC, Hunter Water) risk assessment was conducted for
pesticides and SOCs across the catchment. From the risk assessment, changes were proposed to the
list of pesticides and SOCs routinely monitored by SCA in our water supplied to customers. The
recommendations were based on both the likelihood of use in the catchment and the toxicity of
chemicals. Pesticide and SOC monitoring in the Water Monitoring Program 2015-2020 have been
updated to reflect the recommendations from the 2012-13 review.
Sydney Catchment Authority Annual Water Quality Monitoring Report 2013-14

4 Applicable guidelines / benchmarks
The SCA has adopted nationally recognised standards and guidelines for a range of water quality
characteristics in each part of the water supply network. Different guidelines and standards apply to
each part of the supply cycle as water passes from catchment waterways into storages, and then into
the delivery network or downstream rivers.
4.1 Australian Drinking Water Guidelines (ADWG) 2011
The Australian Drinking Water Guidelines (NHMRC, 2011) apply to any water intended for drinking,
irrespective of the source or where it is consumed. The ADWG framework for managing drinking
water quality advocates risk management and preventive measures at all barriers from catchment to
consumer.
For water quality characteristics that have been specified as ‘health related’, including metals,
pesticides and synthetic organic compounds (Table 4.1), raw water must conform to the ADWG. As
conventional water treatment methods are not designed to remove these compounds from raw
water, it is preferable to avoid them in the raw water supply through catchment and storage
management practices.
Routine monitoring of radionuclides is also performed at water filtration plants. Radionuclides are
not presented in the results section of this report, but are included in Appendix Tables A20, A39, A60,
A73 and A92. Testing for individual radionuclides is performed in the case of a positive gross alpha or
gross beta result.
4.2 Raw water supply agreements
The SCA has established terms and conditions of supply with wholesale customers to ensure treated
water is not harmful to consumers’ health. Raw water supplied for treatment is required to conform
to site-specific standards specified in raw water supply agreements (Table 4.2). These standards are
based on the treatment capabilities of the plants and the natural characteristics of the catchment.
This ensures that raw water can be treated to meet ADWG requirements.
In 2013 the raw water supply agreement with Sydney Water was renegotiated. Key changes relating
to water quality were the removal of specifications for temperature and pH of raw water supplied by
the SCA. These changes came into effect in October 2013. Compliance for 2013-14 is benchmarked
against the updated specifications. ADWG and site specific standards are applied to samples
collected in the delivery system.

4.3 ANZECC 2000
The Australian and New Zealand Guidelines for Fresh and Marine Water Quality (2000) (referred to
as ANZECC, 2000) provide a guide for setting water quality objectives required to sustain current or
likely future environmental values for natural and semi-natural water resources in Australia and New
Zealand. Water quality in the SCA’s storages and catchment waterways are compared against
relevant sections of the ANZECC Guidelines.
4.4 Benchmarks for storages
Benchmarks for storages are derived from the guidelines for freshwater lakes and reservoirs
(ANZECC, 2000) for the 95-99 percent level of species protection (Table 4.3).

4.8 Benchmarks for cyanobacteria
The SCA routinely monitors levels of algae in major storages to provide early warning of possible
bloom conditions and to ensure that raw water supplied to customers can be treated to meet
drinking water guidelines. Algal monitoring is also conducted to avoid contaminating downstream
waterways through environmental releases or transfers.
Despite Lake Yarrunga and Fitzroy Falls Reservoir being the only SCA storages with recreational
access, the SCA applies the National Health and Medical Research Council Recreational Waters
Guidelines (NHMRC, 2008) for catchments and lakes (Table 4.7). The raw water and picnic areas
benchmarks are from the ADWG.

4.9 Benchmarks for Cryptosporidium and Giardia
The ADWG do not contain guideline values for Cryptosporidium and Giardia in raw or treated
drinking water. However, ADWG (2011) recommends a multi-barrier approach to minimise the risks
of these pathogens. Investigative testing is encouraged in response to events (e.g. heavy rainfall) that
could increase the risk of contamination. The SCA implements additional monitoring during high risk
events.
Cryptosporidium and Giardia monitoring in the catchments is undertaken to provide an early warning
function to enable optimal configuration of the raw water supply system in the event of high levels of
Cryptosporidium and/or Giardia detections within the storages. Catchment monitoring also
contributes to the understanding of sources which can then improve the robustness of risk
assessments and catchment actions.
The SCA responds to detections of Cryptosporidium and Giardia in raw water supply in accordance
with the Raw Water Quality Incident Response Plan (RWQIRP) developed in consultation with NSW
Health and wholesale customers. The SCA’s RWQIRP identifies four event levels for raw water:
 Alert Level: 1 – 10 (oo)cysts (IFA /10 L adjusted for recovery)
 Minor Incident: 11 – 100 (oo)cysts (IFA /10 L adjusted for recovery)
 Major Incident: 101 – 1000 (oo)cysts (IFA /10 L adjusted for recovery)
 Emergency: >1000 (oo)cysts (IFA /10 L adjusted for recovery).

5 Routine monitoring
5.1 Quality Assurance/Quality Control
During 2013-14, 5198 routine samples were collected for testing. There were 537 quality assurance
and quality control (QA/QC) samples taken over this period which is equivalent to 10.3% of the
routine samples collected. This included 272 duplicate samples (5.2%), 128 field blanks (2.5%) and
137 trip blanks (2.6%). See Glossary for descriptions of types of QA/QC samples.
In 2013-14, there were 31 QA/QC samples that had anomalous results, indicating a possible process
issue. These issues were logged and investigated by members of the SCA QA/QC working group. In all
cases, raw data was checked and verified and the results confirmed with the laboratory before
further investigation. Retesting was performed where possible to confirm the result.
Of the 31 QA/QC anomalies, six were because of detections in trip blanks (4% of total trip blanks
analysed), nine were because of detections in field blanks (7% of total field blanks) and 16 were
because of unsatisfactory variation in duplicate sample analyses (6% of total duplicate analyses). The
SCA tracks these types of anomalies to determine if any emerging trends warrant corrective action.
There was no evidence of this in 2013-14.
Trip blanks
One trip blank had a detection of filtered aluminium, two trip blanks had detections of dissolved
organic carbon, two trip blanks had detections of oxidised nitrogen and one trip blank had a
detection of chlorophyll-a, lorenzen and phaeophytin. This anomaly prompted a process audit but no
issues or recommendations were identified. In all but the chlorophyll-a anomaly, all detections were
very low, just above the limit of reporting and would not significantly impact on the interpretation of
sample results.
Field blanks
In the field blanks, total organic carbon, dissolved organic carbon, total nitrogen, Kjeldahl nitrogen,
oxidised nitrogen, ammonia, aluminium, manganese, sodium, chloride and reactive phosphorus were
detected on no more than three occasions. Most detections were very low, just above the limit of
reporting and would not significantly impact on interpretation of sample results.
Duplicates
In the sixteen duplicate anomalies, duplicate sample had differences above the laboratory
acceptance criteria for algae, chlorophyll-a and lorenzen, E. coli, faecal coliforms, true colour,
aluminium, manganese and nitrogen. Duplicate sample variations were infrequent, variable and did
not indicate any systematic issues with sampling and/or laboratory quality control and assurance
processes.

5.2.1
Catchments
As in previous years, nutrients (nitrogen and phosphorus) and chlorophyll-a regularly exceeded
ANZECC benchmarks in 2013-2014. Protected natural catchments (Kowmung, Little and Tonalli
Rivers) experience much lower concentrations than those catchments dominated by agricultural and
urban land-uses (e.g. Wollondilly, Mulwarree and Wingecarribee Rivers). This is particularly evident
at sites downstream of sewage treatment plants (Farmers and Gibbergunyah Creeks).
Despite regularly exceeding ANZECC benchmarks for nutrients and chlorophyll-a, all sites remained
well below algal guidelines (NHMRC, 2008).
5.2.2
Storages
Nutrient concentrations in Lake Burragorang peaked in August 2013, following significant inflows in
June-July 2013. Despite the relatively large concentrations, algal activity in spring 2013 was moderate
with chlorophyll-a concentrations around the seasonal average. Toxins (Microcystin) remained below
the limit of detection.
Turbidity remained very low throughout the reporting period, despite a number of minor to
moderate inflow events. True colour persisted above historical averages, yet below levels of 20122013. The SCA worked with SWC in selecting supply depth to ensure optimal water quality.
5.2.3
Water Filtration Plants
For the 2013-2014 reporting period, there were no water sample results outside of the raw water
supply agreement (RWSA) standards for raw water supplied to Warragamba, Orchard Hills and
Prospect water filtration plants. All water samples were well below ADWG for health related
characteristics.

5.3.1
Catchments
Upper Nepean catchment sites continued to perform well against ANZECC benchmarks and
demonstrate the benefit of Special Areas. pH was regularly outside the ANZECC benchmark range but
is considered to be the natural condition and the result of local geology.
5.3.2
Storages
Water quality in Upper Nepean storages continued high compliance against ANZECC benchmarks.
Algal growth remained low despite high nutrient concentrations in some lakes (e.g. Lake Nepean).
Much like the catchment sites, local geology results in pH levels outside of the ANZECC range. This is
also thought to contribute to aluminium concentrations above ANZECC benchmarks.
A bushfire in October 2013 burnt out approximately 14% of the Upper Nepean catchment area.
Special monitoring of the most affected storage; Lake Nepean, did not identify any significant
impacts to water quality.
5.3.3
Water Filtration Plants
For the 2013-2014 reporting period, there were no water sample results outside of the raw water
supply agreement standards for raw water supplied to Illawarra and Nepean water filtration plants.
There were two instances where water hardness was below the site specific standard in the raw
water supply agreement for water supplied to Macarthur water filtration plant. The Upper Nepean
storages all have very soft water, particularly Lake Cataract and Lake Nepean and water hardness
appears to have declined slightly this year compared to last year in the lakes, leading to the dips
below the lower limit of the site specific standards for Macarthur water filtration plant. Low hardness
may require minor configuration adjustment at the water filtration plant, but does not pose a health
risk.
At times, high true colour (primarily from Lake Nepean) and low turbidities resulted in treatment
difficulties at Nepean and Macarthur water filtration plants. Both true colour and turbidity remained
below RWSA standards.
All samples were below ADWG for health related characteristics.

5.4.1
Catchments
Water quality at Lake Woronora catchment sites was consistently good with only pH being below the
ANZECC benchmark. Much like the catchment of the Upper Nepean system, low pH in the Woronora
River catchment is common due to groundwater infiltration from surrounding Hawkesbury
sandstone.
5.4.2
Storage
Water quality in Lake Woronora remained good, with very high compliance against ANZECC
benchmarks. Naturally low pH water from the Woronora River resulted in some samples falling
below the ANZECC benchmark.
5.4.3
Water Filtration Plant
Consistent with previous years, Woronora water filtration plant was compliant with RWSA standards
and ADWG for all samples.

5.5.1
Catchments
The Blue Mountains catchments are very small (less than 20 sq km in total) and inflow water quality
is represented by water quality in the lakes. There are no routine monitoring sites in the Blue
Mountains catchments.
5.5.2
Storages
Typical of the Blue Mountains lakes, dissolved oxygen was regularly below the ANZECC benchmark of
90% saturation. In Upper and Lower Cascade dissolved oxygen remained above 70% saturation for
most samples, whereas in Lake Greaves, times of low oxygen were experienced due to problems with
the destratification unit used to keep this storage mixed and aerated. This is also why Lake Greaves
had notable exceedences for aluminium and phosphorus (anoxic conditions promoting release from
sediments).
Despite low nutrient concentrations, chlorophyll-a concentrations were higher than previous years.
Speciation indicated a non-toxic diatom Urosolenia as the dominant species in Top Cascade.
5.5.3
Water Filtration Plants
All samples at Cascade water filtration plant were within the raw supply agreement standards. Algal
ASU was not an issue despite the increase in algal activity.
All samples were below ADWG for health related characteristics.

5.6.1
Catchments
As in previous reporting periods, nutrients were regularly above the ANZECC benchmark while
chlorophyll-a rarely exceeded the 5 ug/L benchmark. Located directly downstream of the Braidwood
township and sewage treatment plant, the Gillamatong Creek site recorded the highest nutrient and
chlorophyll-a concentrations. Further downstream concentrations are significantly reduced by
dilution and in-stream processes.
5.6.2
Storages
All storages with the Shoalhaven system continued to record high non-compliance with nutrient and
chlorophyll-a benchmarks, particularly the transfer storages Bendeela Pondage, Fitzroy Falls
Reservoir and Wingecarribee Reservoir. Speciation identified mostly non-toxin producing species
thus ADWG and NHMRC recreational guidelines were never exceeded.
5.6.3
Water Filtration Plants
Two samples at Kangaroo Valley water filtration plant exceeded the RWSA standard for algal cross
sectional area (ASU), leading to shortened filter run times in the plant. Management of this issue is
described in section 8.2.1. No health related algal guidelines were exceeded.
All other water quality parameters were maintained within the raw water supply agreement
standards for Kangaroo Valley and Wingecarribee Shire Council water filtration plants. All samples
were below ADWG for health related characteristics.
5.7 Algal monitoring
The SCA samples for algae and cyanobacteria concurrently with routine catchment and storage
monitoring (Section 3.2). At locations with a history of algal activity, seasonal monitoring is
conducted more frequently in the warmer months between October and May to facilitate early
detection of emerging algal events. Routine algal monitoring at WFPs is also undertaken.
Reported results consider both routine and seasonal monitoring. Statistical summaries are provided
in Appendix A. Refer to Section 4.8 for relevant benchmarks.
5.7.1
Warragamba system
All Warragamba catchment sites complied with the recreational guidelines for potentially toxin
producing cyanobacteria count, toxicity and cyanobacteria biovolume.
Waterways in the Wollondilly River catchment frequently exceeded the chlorophyll-a criterion,
particularly Wingecarribee River at Berrima Weir, which exceeded the threshold most of the year
Sydney Catchment Authority Annual Water Quality Monitoring Report 2013-14
46
(maximum of 43 µg/L). The highest chlorophyll-a concentration in the Wollondilly sub-catchment
was 55 µg/L near Goulburn. Sites in the Coxs River subcatchment exceeded the chlorophyll-a
threshold less often. One site in the Nattai River exceeded the chlorophyll-a thresholds for half of the
year (maximum of 7.5 µg/L), while the other site only had a single exceedance.
All Lake Burragorang sites complied with the NHMRC recreational benchmarks. Chlorophyll-a
concentration exceeded 5 μg/L at all locations on occasion, with the highest result of 13.5 μg/L
recorded in the upper reaches of the Coxs River arm. Populations of potential toxin producing algal
species remained low, similar to concentrations observed in 2013-14 and where analysed, no algal
toxins were detected.
Chlorophyll-a concentrations in Prospect Reservoir exceeded 5 μg/L in less than 30% of the routine
samples collected. Concentrations of potential toxin producing algal species remained below
threshold levels of concern and no algal toxins were detected.
Raw water supplied to Orchard Hills, Warragamba and Prospect WFPs continued to meet ADWG
criteria with respect to algae, with no detections of potential toxin producing cyanobacteria such as
Anabaena circinalis or Microcystis aeruginosa.
5.7.2
Upper Nepean system
Catchment sites in the Upper Nepean system showed very little sign of algae in 2013-14, only
exceeding the chlorophyll-a trigger (5 μg/L) for additional analysis in two samples from the Cordeaux
catchment, with a maximum of 6.8 μg/L (compared to a maximum of 80.5 μg/L in Goondarin Creek in
2012-13). Potentially toxin-producing cyanobacteria was not reported at any of these sites.
Similarly, storage sites in the Upper Nepean rarely exceeded the 5 μg/L Chlorophyll-a criterion for
additional algal analysis. Potentially toxin producing species were rarely detected and toxin analysis
was not required.
Raw water supplied to Macarthur, Nepean and Illawarra WFPs complied with the cyanobacteria
guidelines during 2013-14, with only very low levels of potential toxin producing species observed in
Nepean and Macarthur raw water.
5.7.3
Woronora system
As in previous years, chlorophyll-a remained below the threshold for additional analysis in catchment
and lake sites and no potentially toxin producing species were detected in raw water supplied for
treatment.
5.7.4
Blue Mountains system
Chlorophyll-a concentrations exceeded 5 µg/L in over 40% of routine samples in Upper Cascades and
Greaves Creek storages (maximum of 14.9 µg/L) but no potentially toxin producing species were
detected. Elevated chlorophyll-a was associated with non-toxic diatoms which temporarily caused
Sydney Catchment Authority Annual Water Quality Monitoring Report 2013-14
47
elevated algal ASU (an indicator of filter clogging potential) in raw water supplied to Cascades WFP
(refer to minor incident in Appendix B). The plant had no issues treating the raw water supplied.
5.7.5
Shoalhaven system
Algal blooms are historically common in the Shoalhaven system and chlorophyll-a exceeded the
5 μg/L threshold in most catchment sites at least once during the year, with a maximum of 99 μg/L in
Gillamatong Creek, near Braidwood. However, as in 2012-13, potential toxin producing species were
not detected.
Chlorophyll-a exceeded the 5 μg/L threshold in almost all lake samples from Bendeela Pondage and
Fitzroy Falls Reservoir and almost half of the samples from Lake Yarrunga, including 70% of samples
from the Kangaroo Valley arm. However, all lake sites complied with the guidelines for potentially
toxin-producing cyanobacteria cell counts, toxicity and cyanobacteria biovolume. An unknown
species of Microcystis was reported in ten out of 35 samples in the Kangaroo Valley site with a
maximum of 6,150 cells/mL, but microcystin toxin was below detectable levels.
Raw water supplied to Kangaroo Valley and Wingecarribee WFPs complied with ADWG cyanobacteria
guidelines and did not require toxicity analysis due to very low algal cell counts.
5.8 Cryptosporidium and Giardia monitoring
Routine monitoring is undertaken in catchments, storages and delivery networks at varying
frequencies as agreed between the SCA, Sydney Water and NSW Health. Statistical summaries are
provided in Appendix A.
5.8.1
Catchments
Monitoring for Cryptosporidium and Giardia is undertaken at eight selected streams in the
Warragamba catchment as part of an ongoing pathogens program. The sampling schedule is
monthly, except for Werriberri Creek (E531) which is weekly.
Cryptosporidium oocysts were detected at low concentrations (up to 5 oocysts IFA/10L) at five sites:
Kowmung River (E130), Kedumba River (E157), Werriberri Creek (E531), Wollondilly River (E488) and
Little River (E243). Overall, oocysts were detected in 7% of samples from all sites (excluding
Gibbergunyah Creek E203). In contrast, as in previous years, Gibbergunyah Creek (E203) registered
the greatest Cryptosporidium content (75% of samples with up to 62 oocysts IFA/10L).
Over the last three years there has been no notable change in the frequency of Cryptosporidium and
Giardia detected in catchment sites.
Giardia was once again most common at Gibbergunyah Creek (E203), being detected in all samples.
The median concentration of Giardia observed at this site was 44 cysts IFA/10L with a maximum of
253 cysts IFA/10L. Giardia cysts were detected infrequently at the other sites and when cysts were
Sydney Catchment Authority Annual Water Quality Monitoring Report 2013-14
48
detected in the Kowmung, Kedumba and Wollondilly rivers and Werriberri Creek they were at low
concentrations (up to 5 cysts IFA/10L).
Special testing has previously found that 100% of Cryptosporidium oocysts present at Gibbergunyah
Creek (E203) are non-infectious. Consequently, the occurrence of elevated (oo)cyst counts at this
site, which is located downstream of the point where UV-disinfected STP effluent is discharged, does
not pose a Giardia/Cryptosporidium risk. The evidence of this investigation as well as the research
into sewage treatment efficacy for Cryptosporidium inactivation (see 7.3.2.8) have demonstrated
that monitoring Cryptosporidium and Giardia at E203 should cease as it is not a high risk catchment
site. With the endorsement of the catchment auditor and NSW Health, Cryptosporidium and Giardia
analysis for E203 has been removed from the Water Monitoring Program as of July 2014.
5.8.2
Storages
Routine monitoring was conducted six days per week at one lake site (DWA2) in Lake Burragorang,
twice weekly at two sites (RPR1 and RPR6) in Prospect Reservoir, and weekly at one site (DWI1) in
Wingecarribee Reservoir. (Oo)cysts did not exceed the alert level at any of the lake sites during 201314. Both Cryptosporidium and Giardia were detected infrequently and at low concentrations in these
samples. Cryptosporidium was detected in 1.9% of samples from DWA2 (up to 4 oocysts IFA/10L) and
one percent and four percent of samples from RPR1 and RPR6, respectively (up to 3 oocysts IFA/10L).
Giardia was detected in 1.3% of samples from DWA2 (up to 3 cysts IFA/10L) and two to six percent of
samples from the other three sites (up to 5 cysts IFA/10L). The results are detailed in Appendix A.
Over the last three years there has been no notable change in the frequency of Cryptosporidium and
Giardia detected in storages.
5.8.3
Water Filtration Plants
A joint monitoring program in raw water at the water filtration plants is undertaken by Sydney Water
and results are provided to the SCA and NSW Health for:
 Macarthur WFP (MACSP1A)
 Prospect WFP (composite sample)
 Nepean, Illawarra, Woronora and Cascade WFP composite (COMP16).
The Prospect WFP sample is a composite of the sources supplying raw water. Approximately 92% and
95% of samples were below the level of detection for Cryptosporidium and Giardia respectively. All of
the (oo)cysts were at very low concentrations (maximum of 3 oocysts/10L and 2 cysts/10L).
Pathogen concentrations were below the limit of detection for the vast majority of Macarthur WFP
supply samples. Cryptosporidium was detected in two of 52 samples at concentrations ranging from
approximately 1–2 oocyst IFA/10L. Giardia was detected in one of 52 samples at a concentration of
approximately 1 cyst IFA/10L. Similarly, Cryptosporidium and Giardia were rarely detected from
COMP16 samples. Cryptosporidium was not detected from the 52 samples collected during the year
and Giardia was detected in a single sample at a concentration of 1 cyst IFA/10L.

Over the last three years there has been no notable change in the frequency of Cryptosporidium and
Giardia detected in WFP supply.
5.9 Picnic area monitoring
Routine monitoring is undertaken in Avon, Cataract, Cordeaux and Fitzroy Falls picnic area taps
where disinfected water is supplied directly from storages after chlorination (excluding Fitzroy Falls
Reservoir). The results from picnic area monitoring are compared to applicable guidelines (section
4.7) and are presented in Table 5.6. Refer to Appendices A2.4 (Upper Nepean) and A5.4 (Fitzroy Falls)
for the statistical summaries of the data.

Results were generally consistent with last year. Chlorine residual was frequently outside of the
NHMRC guidelines at all four picnic areas (0.2-0.5 mg/L residual chlorine). In the case of Cataract and
Fitzroy Falls picnic areas, this was often due to chlorine residuals being above the guideline range,
whereas at Avon and Cordeaux picnic areas this was more likely due to chlorine levels being below
the guideline range. Testing for E.Coli was used to confirm effectiveness of disinfection. Public use of
water from picnic taps can be low and variable, which leads to long water age and chlorine decay in
the reticulation system. This is why at Avon and Cordeaux picnic areas residuals are often below
guidelines. Cataract picnic area has a recirculation system to re-dose chlorine to maintain residual
and Fitzroy Falls picnic area is supplied by water tanker from a nearby potable water supply and rechlorinated on site. This is why these locations often have elevated chlorine residual. There were
only infrequent excedeences of the NHMRC Health guideline of 5 µg/L (3 times at Avon, twice at
Fitzroy Falls and once at Cataract picnic area).
Cataract and Cordeaux picnic areas often had iron and occasionally manganese and aluminium above
the aesthetic guidelines. Cataract picnic area in particular frequently had iron above the 0.3 mg/L
NHMRC aesthetic guideline (98% samples). This is similar to last year and reflects the nature of the
Upper Nepean catchments which are naturally high in iron and other metals.
There were also 10% of samples from Cataract picnic area that had turbidity above the 5 NTU
aesthetic guideline. These elevated levels occurred after significant rainfall in March that increased
the turbidity in Lake Cataract and affected turbidity in the picnic area supply for a period of 3 weeks.
Chlorine concentrations was adjusted to ensure effective disinfection. The inflows were also the
cause of some of the higher iron, manganese and aluminium levels in the picnic area supply.
Sydney Catchment Authority Annual Water Quality Monitoring Report 2013-14

Fitzroy Falls picnic area was the only site that had chlorophyll-a above the 5 µg/L trigger value for
algal analysis (two samples in January 2014). Further analysis revealed no algae was present in the
sample and an investigation was carried out into the cause of the elevated chlorophyll-a levels.
Investigative monitoring did not detect chlorophyll-a at any stage of the supply chain and the cause
of the elevated levels was not able to be determined. The supply and monitoring process was
audited to ensure conformance to operational guidelines.
SCA has developed a Drinking Water Management Plan and has adopted the NSW Private Water
Supply Guidelines (NSW Health, 2014) as part of our actions to conform with the amendments to the
NSW Public Health Act (2010). As such in future, chlorine residual targets will change from 0.2-0.5
mg/L to >0.5 mg/L which affect our management and reporting of chlorine residuals at picnic areas.
As part of the drinking water management plan critical control points have been set for chlorine
dosing and selective abstraction (depth of water in lake where supply is sourced from).
5.10 Dam seepage monitoring
Chemical monitoring of seepage waters is conducted at the SCA dams to:
 Determine the origin and/or path of leakage
 Assess concrete degradation
 Assess dispersive behaviour and erodability of embankment and foundation materials.
The dams sampled for chemical analysis of seepage waters this year were Avon, Cataract, Cordeaux,
Nepean, Prospect, Tallowa, Warragamba, Wingecarribee and Woronora. All of these dams are tested
annually.
Prospect and Wingecarribee dams are of earth embankment construction and are tested for a variety
of metals, particularly their sodium absorption ratio. Metals testing is also conducted at concrete and
masonry construction dams (Avon, Cataract, Cordeaux, Nepean, Tallowa, Warragamba and
Woronora), with net calcium levels measured as the key indicator of concrete degradation.
A site upstream in the storage is tested at all dams to provide a control point. A variety of sites
downstream at these dams are also tested. For example, net levels of calcium (i.e. calcium levels at
the test site minus calcium levels in the storage water) are included in an equation to determine
concrete degradation rates.
No safety concerns (relating to chemical monitoring or concrete degradation) were identified for any
dams during 2013-14.

Water quality in the Hawkesbury-Nepean system typically declines in a downstream direction. This
trend is particularly evident in chlorophyll-a concentration, which increases rapidly downstream of
SCA control structures (Pheasants Nest, Broughtons Pass).
Dissolved oxygen and pH at The Needles (Woronora River) were outside of ANZECC benchmarks for a
majority of samples. Much like pH in Lake Woronora and Woronora River (upstream of Lake
Woronora), pH was below the ANZECC benchmark and is the result of natural conditions. Dissolved
oxygen was below ANZECC benchmarks yet above 50% saturation. At this level, ecological
communities are not considered to be impacted.
6.2 Water quantity
Inflows for the 2013-2014 reporting period were slightly under the historical average (based on the
1996-2014 period). All storages operated at high capacities throughout the period, with very little
water transferred between systems. Figure 6.1 presents the annual inflows and transfers to key SCA
storages for the period 1996-2014.

Environmental release requirements for Woronora, Cataract, Cordeaux, Avon, Nepean, Broughtons
Pass, Pheasants Nest and Tallowa are calculated as a function of inflows on a daily basis. There is a
fixed environmental flow requirement for Wingecarribee Reservoir. Below is a summary of the
releases for these dams and weirs.
6.2.1
Upper Nepean system
6.2.1.1 Cataract Dam
Figure 6.2 shows the environmental flow releases and spills from Cataract Dam over the 2013-14
reporting period.
Figure 6.2: Environmental releases and spills – Cataract Dam
Approximately 14,700 ML was discharged as environmental flows from Cataract Dam in 2013‐14. The
releases ranged from a minimum of 1 ML/d up to 519 ML/d in July, 2013. The average release over
the 12 months was 40 ML/d.
Following the storm event in late March 2014 (refer to section 8.1 for details), releases from Cataract
Dam were reduced to 50 ML/d to reduce turbidity in raw water supplied to Macarthur WFP.
Environmental releases were also limited to 350 ML/d while the release valve was repaired. NSW
Sydney Catchment Authority Annual Water Quality Monitoring Report 2013-14

Office of Water was notified of these issues and agreed to the SCA’s proposal for making up release
shortfalls as per the agreed protocol. The valve was repaired and shortfalls made up by 9 April 2014.
6.2.1.2 Cordeaux Dam
Figure 6.3 shows the environmental flow releases and spills from Cordeaux Dam over the 2013-14
reporting period.
Figure 6.3: Environmental releases and spills – Cordeaux Dam
Approximately 8,900 ML was discharged as environmental flows from Cordeaux Dam in 2013‐14. The
releases ranged from a minimum of 1 ML/d up to 485 ML/d in July, 2013. The average release over
the 12 months was 25 ML/d.
6.2.1.3 Avon Dam
Figure 6.4 shows the environmental flow releases and spills from Avon Dam over the 2013-2014
reporting period.
Figure 6.4: Environmental releases and spills – Avon Dam
Approximately 11,400 ML was discharged as environmental flows from Avon Dam in 2013‐14. The
releases ranged from a minimum of 1 ML/d up to 742 ML/d in July, 2013. The average release over
the 12 months was 31 ML/d.
There was a short period in March, 2014 when required release exceeded output capacity. The
shortfall was made up in the following week in consultation with NSW Office of Water.

6.2.1.4 Nepean Dam
Figure 6.5 shows the environmental flow releases and spills from Nepean Dam over the 2013-2014
reporting period.
Figure 6.5: Environmental releases and spills – Nepean Dam
Approximately 11,150 ML was discharged as environmental flows from Nepean Dam in 2013‐14. The
releases ranged from a minimum of 1 ML/d up to 460 ML/d in September, 2013. The average release
over the 12 months was 31 ML/d. Nepean Dam spilled throughout July and August, 2013 followed by
another spill event in late September, 2013. A maximum spill of 2400ML/d occurred in September,
2013 with a total of 27,700ML spilling over the 12 month period.
6.2.1.5 Broughtons Pass Weir
Figure 6.6 shows the environmental flow releases and spills from Broughtons Pass Weir over the
2013-2014 reporting period.
Figure 6.6: Environmental releases – Broughtons Pass Weir
Approximately 19,200 ML was discharged as environmental flows from Broughtons Pass Weir in
2013‐14. The releases ranged from a minimum of 1 ML/d up to 798 ML/d in July, 2013. The average
release over the 12 months was 52 ML/d.
6.2.1.6 Pheasants Nest Weir

6.2.3.1 Tallowa Dam
Figure 6.9 shows the environmental flow releases and spills from Tallowa Dam over the 2013-2014
reporting period.

56
Figure 6.9: Environmental releases and spills – Tallowa Dam
Approximately 204,000 ML was discharged as environmental flows from Tallowa Dam in 2013‐14.
The releases ranged from a minimum of 46 ML/d up to 11,700 ML/d in March, 2014. The average
release over the 12 months was 560 ML/d. Occasional shortfalls in daily release requirements
occurred sporadically during the year due to failure of the automatic daily release setting on the
overshot gate. The fault was compounded by fluctuating storage levels in Tallowa Dam due to hydroelectric generation by Origin Energy. Each instance was reported to NSW Office of Water who agreed
with the SCA’s strategy for manually setting daily releases and making up for shortfalls as per agreed
protocols.
Spills were recorded throughout the year, with a maximum spill of 23,000 ML/d occurring in
September, 2013. A total of 240,00ML spilled from Tallowa Dam over the 12 month period.
6.3 Thermal impacts of environmental releases
Water released from storages can often be significantly warmer or cooler than downstream systems
due to depth of offtake, thermal stratification and greater thermal mass. Large releases of thermally
disparate waters into downstream systems can significantly impact on downstream riverine systems
though disruption of fish migration and alteration of macroinvertebrate assemblages. To investigate
the effect of environmental releases, water temperature is measured at a number of locations
downstream of SCA storages.
To determine potential thermal impacts, the temperature of storage inflows and environmental
releases for the reporting period are compared. In this instance, storage inflows provide a measure
of expected water temperatures in the natural conditions. Downstream temperatures are taken from
the closest downstream hydrometric station.
Only systems with Environmental Flow conditions are presented, namely the Upper Nepean,
Woronora and Shoalhaven systems.
6.3.1
Upper Nepean system
The Upper Nepean System comprises of the Avon, Cataract, Cordeaux and Nepean catchments, all of
which are subject to environmental releases. While the SCA endeavours to provide the highest
Sydney Catchment Authority Annual Water Quality Monitoring Report 2013-14
57
quality water for environmental release, system configuration precludes diversion specifically for
environmental releases from the Upper Nepean storages. As such, all Upper Nepean environmental
releases are sourced from offtake depths determined to provide the highest quality water for human
consumption. As such, the SCA is particularly interested in detecting suppressed downstream water
temperatures as a result of deep water offtakes.
Daily temperature data was recorded at the following SCA hydrometrics stations and represent
reference catchment conditions:
 Avon catchment - Avon River at Summit Tank
 Cataract catchment – Cataract River at Corrimal
 Cordeaux catchment – Sandy creek at Fire Road 15
 Nepean catchment – Nepean River at Nepean Dam inflow
Downstream water temperature was recorded at Menangle Weir on the Nepean River which
represents the first hydrometric station after the confluence of all Upper Nepean Storage releases.
The station is approximately 20km downstream of the furthest Upper Nepean storage, Lake
Cordeaux.
As shown in Figure 6.10, downstream temperatures at Menangle Weir are consistently higher than
the inflow reference temperatures, indicating no persistent downstream cold water pollution as a
result of environmental releases. Furthermore, downstream temperatures and reference
temperature profiles exhibit small scale changes and seasonal trends. Reference temperatures
display greater small scale variability resulting from their smaller flow.
Figure 6.10: Upper Nepean system temperature profile
6.3.2
Woronora system
As with the Upper Nepean storages, the system configuration at Lake Woronora does not support
offtakes specifically for environmental releases. As a result, environmental releases may be
significantly cooler than surface waters due to thermal stratification. Downstream water
Sydney Catchment Authority Annual Water Quality Monitoring Report 2013-14
58
temperatures in the Woronora River are analysed to detect any evidence of persistent cold water
pollution.
Reference temperatures for the Woronora catchment are recorded daily at the major inflow
locations to Lake Woronora:
 Woronora River at Fire Rd 9F
 Waratah Rivulet at Fire Rd 95
Downstream temperatures were recorded daily at The Needles on the Woronora River,
approximately 10km downstream from the environmental release point.
As seen in Figure 6.11, the downstream temperature at The Needles closely matches that of the
reference temperatures. Both show a strong seasonal trend and show very similar small scale
variations resulting from local weather conditions.
Figure 6.11: Woronora system temperature profile
6.3.3
Shoalhaven system
Since 2008, environmental releases from Lake Yarrunga have been predominantly supplied via an
overshot gate on the dam which allows for the preferential release of surface waters. There is also a
high level outlet which contributes to the environmental release via the fishway. As surface waters
aren’t subject to thermal stratification, they should more closely match downstream temperatures.
Reference temperatures for Lake Yarrunga are recorded daily on the major tributaries:
 Shoalhaven River at Fossickers Flat
 Kangaroo River at Hampden Bridge
Downstream temperatures were recorded daily at:
 Shoalhaven River downstream of Tallowa Dam
 Shoalhaven River at Grassy Gully
Sydney Catchment Authority Annual Water Quality Monitoring Report 2013-14
59
The downstream site at Tallowa Dam is immediately downstream of the environmental releases and
provides a good measure of the release temperature. Grassy Gully is approximately 20km further
downstream.
Figure 6.12 clearly shows that temperatures at both downstream sites closely match those of the
upstream Shoalhaven reference site. The similarity between the two downstream sites suggests the
environmental releases are very near ambient condition.
The Kangaroo River catchment is small, so temperatures fluctuate more in response to local rain
events. Considering the Shoalhaven River contributed 5-6 times more water during the reporting
period, the site at Fossickers Flat is a more relevant reference for comparing upstream and
downstream temperatures.

7 Targeted and investigative monitoring
The SCA undertakes targeted and investigative monitoring to understand and assess impacts that are
not addressed by the routine monitoring program. The results of the monitoring are discussed in
greater detail in the sections below.
A summary of water quality incidents during 2013-14 is included in Section 8.
7.1 Wet weather inflow monitoring
To assist in evaluating impacts on water quality from runoff during significant rainfall events, the SCA
undertakes wet weather sampling. A key component of the wet weather monitoring program is the
use of autosampler stations at strategic catchment sites which are programmed to automatically
take samples once a river height trigger has been reached.
Wet weather monitoring is used to quantify the water quality risks for incoming waters to storages.
During high rainfall events, catchments are often closed to operational traffic and storages closed to
boat traffic to protect the health and safety of staff and members of the public. Using auto-samplers
helps to acquire valuable water quality information on the water quality effects of rainfall events.
The SCA maintains two types of autosamplers, measuring the following analytes:
 Type 1 – total organic carbon, suspended solids, total phosphorus, total nitrogen, total
aluminium, total iron and total manganese.
 Type 2 – total nitrogen, total phosphorus, Cryptosporidium and Giardia.
Where specific water quality issues have been identified, additional characteristics are analysed on
request. At high priority reservoir inflow locations, both auto-sampler types have been installed.
Given the differing sampling mechanisms, trigger values may differ between the two autosampler
types. Type 2 samples are reserved for locations identified as potentially significant pathogen
sources, requiring a much larger sample volume (hence the lower number of samples). Table 7.1
shows number of samples collected for each site during the year.

7.2 Macroinvertebrate monitoring
The Macroinvertebrate Monitoring Program (MMP) is an annual assessment of the ecological health
of river sites in the SCA’s drinking water supply catchment. Macroinvertebrate sampling was
conducted at 61 sites in 27 sub-catchments, collecting 121 individual samples, a slight increase
compared with the 2012 MMP. Sampling sites and assessments are presented in Figure 7.1. Results
were generally similar to 2012 program. No sites were in above reference condition (compared to
one site in 2012) but there was only one site well below reference condition (compared to three sites
in 2012).
Macroinvertebrate sampling was conducted at 26 sites from 12 sub‐catchments in the Warragamba
catchment in 2013. Sixty five percent of sites were rated to be in a reference or above reference
condition, an improvement on the 2012 results.
Sydney Catchment Authority Annual Water Quality Monitoring Report 2013-14
62
Twelve sub‐catchments were sampled in the Shoalhaven catchment, with macroinvertebrate
monitoring conducted at 26 sites in 2013. Nearly 40% of sites had AUSRIVAS ratings in a reference
condition, but none above reference condition. Catchment wide, this is an improvement when
compared to the previous year’s findings.
Four sites in the Metropolitan catchment were sampled for macroinvertebrates in 2013. Only one of
the four sites sampled in the Metropolitan catchment was rated in 2013 to be in reference condition,
with the remaining sites rated to be below reference condition. This result is the same as the 2012
assessment. Health in the Woronora sub-catchment improved compared to last year, with one site in
reference condition and one site below reference.
AUSRIVAS ratings for the three Blue Mountains sub-catchment sites were similar to 2012 and ranged
from reference to below reference condition.

7.3 Investigative monitoring
The SCA’s investigative monitoring program is designed to target known risks, emerging issues and to
enhance modelling and management options. Investigative monitoring can be used for identifying
pollution sources, understanding pollutant fate and transport in a variety of flow conditions, and
investigating the risk of pollutants reaching inflows and raw water off-take points. Investigative
monitoring is also one method used in evaluating the effectiveness of actions in the catchments and
storages to address pollutants.
7.3.1
Investigative monitoring for operational decision making
7.3.1.1 Prospect Reservoir draw down for dam safety works
In agreement with Sydney Water, a monitoring program to assess key water quality parameters is
always implemented prior to and during the planned use of Prospect Reservoir. From 1 July to 28
September 2013 Prospect Water Filtration Plant (WFP) was supplied with water from Prospect
Reservoir. This was done to draw down the Prospect Reservoir to greater than 3.4 m below full
supply to allow for critical dam safety works. This monitoring aims to assess whether the water
quality is acceptable for supply, as Prospect Reservoir is a small reservoir that can experience rapid
changes in water quality.
The outcome of this monitoring was the successful draw down of Prospect Reservoir for the dam
works without compromising water quality supplied to Prospect WFP.
7.3.1.2 Wet weather event June-July 2013
Extended wet weather in late June and early July 2013 caused significant inflows into multiple
storages. Inflow intrusions were present in Lake Burragorang, Lake Nepean, Lake Cataract, Lake
Cordeaux, Lake Avon and Lake Woronora. Additional water quality monitoring was undertaken to
assess the impact of the inflows on supply. This included sampling of the lakes to assess what depth
of water in the lakes were impacted by the inflow, what the magnitude of impacts were and where
the best quality water for supply was located. Extensive post-wet weather event monitoring was
undertaken in Lake Burragorang due to the major changes in water quality caused by this event.
Particularly, elevated colour was causing treatment difficulties at Orchard Hills and Prospect WFPs.
The outcome of this monitoring was the optimisation of offtakes and supply sources under highly
variable conditions. This monitoring also highlighted a gap in our knowledge around the release of
colour causing organics from the catchments during large wet weather events. A research project has
commenced to address this knowledge gap (refer to section 7.3.2).
Monitoring during this event revealed some useful observations regarding protozoan pathogens:
 Sewage overflows contained much more Giardia than Cryptosporidium but Cryptosporidium
dominated in the water at the inflows to Lake Burragorang and within the lake itself. This
suggested that diffuse sources within the catchment were a much greater source of oocysts
than STPs.
Sydney Catchment Authority Annual Water Quality Monitoring Report 2013-14
65



A large proportion of oocysts in samples of sewage and receiving water immediately
downstream of the bypassing STPs were infective.
No infective oocysts were detected in water samples well downstream of the STPs or in Lake
Burragorang. This means that the Cryptosporidium risk from this event was low.
Cryptosporidium oocysts were detected at low-moderate concentrations in the intrusion as
the underflow moved along the lake.
It is not known whether the observations made during this event can be generalised to other events.
A Cryptosporidium and Giardia campaign monitoring program has been developed to inform risk
assessment for future wet weather events.
7.3.1.3 Post-bushfire water quality in the Upper Nepean system
Bushfires in the Southern Highlands in October 2013 affected more than 15,600 hectares of
bushland, including 7,000 hectares of Special Areas surrounding Lake Nepean and the two weirs that
are used to supply Macarthur and Prospect water filtration plants with water from the Upper Nepean
lakes.
In March 2014, intense storms occurred over the bushfire-affected areas (with a total 230mm rainfall
received in a very short period), increasing the risk of iron and nutrients being transported into the
storages and rivers during storm events.
Additional monitoring was undertaken after both of these events to identify risks to water quality,
provide early warning and optimise quality of water supplied to the water filtration plant. Outcomes
of this monitoring are also included in section 8.1.
7.3.2
Scientific research
Eleven science investigations were completed in 2013/14, including three that were contracted to
external providers.
7.3.2.1 Effect of chlorination on Giardia in the Upper Canal
The Upper Canal delivers water in the Upper Nepean storages (Nepean, Avon, Cordeaux and Cataract
reservoirs) from Broughtons Pass to Prospect WFP. The water is chlorinated at the tunnel entrance at
Broughtons Pass. The main purpose of chlorination is to provide Giardia initial kill in the raw water
prior to reaching the Prospect WFP.
The investigation showed that while chlorination of the Upper Canal will reduce the overall Giardia
risk, the filtration and post-filtration chlorination conducted at Prospect WFP is sufficient to reduce
the Giardia risk to an acceptable level without Upper Canal chlorination under the range of flow/rain
conditions represented in the historical data set.

7.3.2.2 Sources of taste and odour producing compounds
Prospect Reservoir is an integral part of Sydney’s water supply system and it is strategically placed as
a potential back up supply. Customer complaints about taste and odour have been attributed to
water quality from Prospect Reservoir in the past with above average complaints coinciding with
time of supply from Prospect Reservoir but there is no direct evidence of correlation. While Prospect
Reservoir has had occasional detections of known taste and odour producing compounds the
definitive sources of these compounds were not well established.
An investigation of the sources of specific taste and odour compounds (MIB and geosmin) in Prospect
Reservoir was initiated to inform mitigation strategies. The study identified ten species of
cyanobacteria in Prospect Reservoir that are known to produce taste and odour compounds, and
confirmed that MIB is the predominant cause of taste and odour.
A collaborative project with the University of Adelaide has commenced to further improve our
understanding of the sources of MIB and geosmin in Prospect Reservoir.
7.3.2.3 Cryptosporidium in kangaroos
This project was designed to resolve uncertainty over whether eastern grey kangaroos in the Sydney
catchment areas are carriers of human-infective strains of Cryptosporidium.
Over a two year period approximately 600 faecal samples were collected from eastern grey
kangaroos. Only 1.7% of the samples contained Cryptosporidium and these were genotypes that are
not considered human infective. The risk to human health from kangaroo faeces is therefore
considered to be very low. Field sampling for this project ceased in June 2014. The work will be
incorporated into a collaborative Australian Research Council (ARC) Linkage Project between the SCA,
Murdoch University and other Australian and international organisations on the health risks of
Cryptosporidium and Giardia in native and introduced animals and the potential for cross infection.
The findings should reduce the need to genotype oocysts from water from catchments with no
human or livestock contamination and assist justify a reduction in baseline pathogen monitoring in
these catchments.
7.3.2.4 Review of pesticides and synthetic organic compounds
The Australian Drinking Water Guidelines (ADWG) released in 2011 nominated guideline values for
147 organic chemicals to consider in health risk assessment. Many of these organics have not been
monitored in SCA reservoirs or catchments. A risk assessment was conducted in consultation with
stakeholders to review pesticide usage within SCA catchments from 2000-2012 leading to a short list
from the ADWG organic chemicals for further risk assessment. The SCA collaborated with EPA and
NSW Department of Primary Industries pesticide experts to collate information on contemporary
pesticide usage in NSW/SCA catchments and emerging products. The risk assessment has led to a
revision of the pesticides and synthetic organic contaminants (SOCs) monitored at inlet to water
filtration plants.

7.3.2.5 Characterising pathogen risk in catchments
A method was developed to assess catchments for microbiological risk and piloted on two SCA
catchments. The catchment assessment method is based on the WSAA two-tier assessment method
that has been modified to incorporate the more detailed catchment information. For the SCA, this is
through the Pollutant Source Assessment Tool and includes a component that utilised quantitative
microbial risk assessment (QMRA) based on long-term Cryptosporidium monitoring data.
The catchment assessments provide scientifically-defensible evidence of microbiological risk in SCA
catchments and forms an integral part of the discussions with NSW Health regarding the health
response required following future WFP turbidity exceedance and will reduce the monitoring
requirement.
The following SCA-sponsored scientific investigations conducted by external providers were reported
in 2013/14:
7.3.2.6 Physico-chemical controls on cyanobacteria in Sydney reservoirs
The aim of this project was to improve understanding of the factors controlling the toxic
cyanobacterial blooms in water reservoirs, with a focus on Microcystis sp. Insight into the forms of
nutrients that are most readily assimilated by toxin-producing species of cyanobacteria prevalent in
water supply reservoirs and an understanding of the spatial and temporal distribution of the forms of
nutrients, and light and temperature will assist in determining the key drivers to occurrence of
blooms of these organisms.
The study shows that nutrient uptake rate increases with greater iron limitation in high-nutrient
conditions, and decreases with greater iron limitation in low-nutrient conditions. Greater iron
limitation increases the production of microcystin toxins in low-nutrient conditions, and does not
have strong influence in high-nutrient conditions. Greater knowledge of toxin genesis should inform
the monitoring required in conditions likely to indicate a possible toxic event.
7.3.2.7 Physical, chemical and microbiological degradation of cyanobacterial compounds
Once cyanobacterial toxins or taste and odour compounds are present in water, it is critical to know
the fate of these compounds. Understanding of the natural removal of the compounds by physical,
chemical and biological mechanisms will be useful for the SCA to determine the potential down time
of the reservoirs after a toxic bloom.
The study found that biodegradation and photolysis are the key processes governing the fate of the
cyanobacteria metabolites in Lake Burragorang, and are influenced by seasonal variations.
Cyanobacteria metabolites are biodegradable, with half-lives from 3 to 36 days. Half-lives for photodegradation range from 2 to 39 days. Cyanotoxins are more easily biodegradable than the taste and
odour causing compounds. The fugacity model developed in this project specifically assesses the fate
Sydney Catchment Authority Annual Water Quality Monitoring Report 2013-14
68
of cyanobacteria exudates, but is suitable for the analysis of any other organic chemical in Lake
Burragorang. These findings will inform post-bloom monitoring.
7.3.2.8 Sewage Treatment Plant Evaluation Study
This study monitors the effectiveness of sewerage projects in reducing pathogenic loads by
determining the loading, infectivity and persistence of pathogens discharged from STPs within the
catchment. Preliminary results show that while Cryptosporidium was consistently present in STP
effluent discharged to catchment streams, none were infectious under normal conditions.
7.3.2.9 Validation of the Grazing Evaluation Model
A preliminary grazing runoff pollutant model is being developed from field trials to more confidently
assess the pollutant exports from grazed hill slopes and the effectiveness of grazing interventions.
The study will inform the selection of future interventions and best management practices for SCA
catchments.
7.3.2.10 Benthic cyanobacteria and taste and odour compounds
This project will provide a robust understanding of the presence, development, measurement and
control of benthic (reservoir bed) cyanobacteria in Prospect Reservoir and their role in generating
taste and odour producing compounds. This study builds on findings from an earlier project to
investigate the sources of MIB and geosmin in Prospect Reservoir.
7.3.2.11 Environmental E. coli
Escherichia coli is an indicator bacterium commonly used to indicate the presence of faecal
contamination in waters. However, some strains of E.coli can grow in water, which can result in a
false warning of faecal contamination. This study aims to identify and ultimately develop a method to
differentiate E.coli strains from faecal and environmental sources and reduce false alarms.
7.3.2.12 Sources and causes of true colour in raw water
A project has been initiated to investigate the sources and causes of true colour in raw water, initially
focussing on Lakes Nepean and Woronora. The project will determine the relationship between
spectra at various wavelengths and other water quality characteristics (e.g. iron, organic carbon). A
sampling campaign has been developed to better understand the spatial and temporal dynamics of
catchment sources of true colour.
8 Incidents and events
Water quality incidents are managed in accordance with the SCA’s Raw Water Quality Incident
Response Plan. The plan sets out agreed water quality trigger levels for various actions and
Sydney Catchment Authority Annual Water Quality Monitoring Report 2013-14
69
notifications. Any issue that poses a potential risk to public health is reported to NSW Health
immediately and incident responses are developed in consultation with relevant stakeholders.
The SCA’s Water Monitoring Program also specifies monitoring required in anticipation of events
which pose potential threats to raw water quality, such as large inflow events and seasonal turnover
in Lake Burragorang. The pre-planned monitoring during periods leading to and during such events
allows operational changes to be made proactively and prevents such events manifesting into
incidents.
During 2013–14 there were no emergency incidents, four major incidents and nine minor water
quality incidents recorded in the SCA’s area of operations (see Appendix B).
8.1 Macarthur storm event
Intense storms over the Upper Nepean catchment areas on Saturday 22 March and Monday 24
March (about 230 mm of rain in total) resulted in highly variable water quality at Broughtons Pass
Weir pool (where water is supplied to Macarthur Water Filtration Plant). These catchments were
affected by bushfire in October 2013, increasing the risk of metals and nutrients being transported
into the rivers and storages during subsequent storm events. The dry summer did not allow ground
cover to re-establish sufficiently to reduce the risk of runoff.
Following the initial storm event, turbidity in Broughtons Pass weir pool rapidly increased, exceeding
100 NTU (major incident threshold for Macarthur water filtration plant raw water is 50 NTU under
typical demand conditions) and variable water quality impacted operation of the water filtration
plant intermittently over the next few days. The plant reported elevated levels of true colour, while
total iron peaked at 1.72 mg/L and moderate levels of E. coli (up to 1,300 orgs/mL) were recorded in
samples taken during the incident. Significant additional monitoring, including surveillance of online
information, was undertaken throughout the event to inform configuration changes.
The SCA worked with Sydney Water to optimise raw water quality, undertaking additional monitoring
and changing the source of supply to reduce the colour and turbidity in the raw water. While the
plant was off line, the SCA closed off supply from Pheasants Nest weir and allowed the more turbid
water to spill over Broughtons Pass weir. The Upper Canal was also temporarily diverted to Prospect
Reservoir. Following the event a formal debrief was held and Sydney Water and NSW Health were
satisfied with the SCA’s response to the incident.
8.2 Major water quality incidents
Other than the Macarthur storm event, the only other major incident level events related to algal
filter clogging potential (ASU), with samples exceeding the respective major incident triggers on
three occasions. Prompt notifications and effective incident response ensured no adverse effects
were experienced in water quality delivered to the WFPs.
Sydney Catchment Authority Annual Water Quality Monitoring Report 2013-14

8.2.1
Elevated Algae Areal Standard Units in Kangaroo Valley raw water
On 28 January 2014 a raw water sample at the inlet to Kangaroo Valley WFP (HKV1) recorded total
algal areal standard units (ASU) of 7,016 ASU/mL. The major incident trigger for raw water supplied
to Kangaroo Valley WFP is 5,000 ASU/mL. There is no health guideline for algae ASU. It is primarily
used as an indicator for the potential for water filtration plant filters to become blocked, slowing
flow through the plant and requiring more frequent filter cleaning.
Diatoms, some of which have filter clogging potential, were the main source of the high ASU in
January, but by February the algal population was dominated by the blue-green algae Cyanonephron.
This type of algae is not known to produce any toxins and is generally not problematic. Algal blooms
are common in Bendeela Pondage in late summer to autumn and blooms of Cyanonephron were
recorded here between March and May in 2012 and 2013.
Algal levels declined below the incident trigger in the monthly raw water sample collected in March,
but again exceeded the major incident threshold in April 2014 (the sample taken on 22 April
recorded 7,862 ASU/mL). In this sample the concentration of Cyanonephron peaked at over 3 million
cells per millilitre before the algal population in Bendeela Pondage gradually declined.
Shoalhaven City Council, which manages the Kangaroo Valley WFP, was notified of these results.
Council reported no issues with treating the water. Operators checked the plant daily to assess the
need for increased chemical cleaning of the membranes. Follow-up seasonal sampling on 28 April in
Bendeela Pondage indicated a significant decrease in the algae ASU to 3,466 ASU/mL. The incident
was downgraded and subsequently closed with further decreases in ASU recorded.
8.2.2
Elevated Algae Areal Standard Units in Prospect raw water
From October 2013 to June 2014, during stage 1 of the Prospect Dam Safety upgrade, Prospect
Reservoir was required to be maintained within a storage level range from 3.7 to 4 metres below full
storage level. Rain events in March and associated diversions of the Upper Canal to the reservoir
caused the storage level to increase above that range, so the SCA prepared to pump from the
reservoir to supply to Prospect WFP. Preparations included implementation of event monitoring as
agreed with Sydney Water to ensure that water quality was within acceptance criteria. This event
monitoring program continued throughout the period of pumping from 29 March to 7 April 2014.
A sample collected on 31 March 2013 recorded 2,002 ASU/mL in the raw water supplied to Prospect
Water Filtration Plant. The major incident trigger level for Prospect WFP is 2,000 ASU/mL. The high
ASU was related to high counts of diatoms present in the sample. Some species of diatoms have
potential to clog filters but are not toxic and do not pose any risk to water quality. The results of this
and other samples collected during the pumping event monitoring program were provided to Sydney
Water. Previous and later raw water samples and samples from Prospect Reservoir showed
comparatively low ASU (in the order of 30 to 150 ASU/mL) with no potentially toxic species of bluegreen algae. The plant reported no issues with treating the water and there was no increase in
customer complaints relating to taste and odour.

Field Blank
For QA/QC purposes, a blank sample measures the magnitude of
contaminant concentration that may have been introduced as a result
of sampling-related activities. Blank water is specially prepared distilled,
deionised or sterilised water that is laboratory produced, qualitycontrolled, and carries a certificate of analyte concentrations for each

contamination.
Field duplicate
The primary purpose of duplicate samples is to identify and/or quantify
the variability in all, or part, of the sampling and analysis system.
Duplicate, triplicate, or greater multiples are considered ‘identical’ or
‘almost identical’ in composition and are analysed for the same
properties. Variations between the primary sample and the duplicate

Algae
Kangaroo
Valley WFP
A sample of raw water supplied to
Kangaroo Valley WFP on
28/01/2014 recorded 7,016
ASU/mL (an indicator of filter
clogging potential). Major incident
trigger for Kangaroo Valley WFP is
5,000 ASU/mL.
Potential for blockage of
membranes at Kangaroo
Valley WFP
Unknown, algal growth is common
in this storage during warmer
weather.
Kangaroo Valley WFP advised and confirmed that plant
was operating OK with no apparent problems.
Operators checked plant daily to assess need for
increased chemical cleaning of membranes. RMContinued monitoring and liaison with WFP Operators.
22-Mar-14
Turbidity
Macarthur
WFP
Following a significant rain event
on 22 March 2014; the turbidity of
the inflows from Pheasants Nest to
Broughton Pass Weir increased
rapidly to above 100 NTU. Major
incident trigger for Macarthur WFP
is 50 NTU (60 NTU when demand is
lower than 80 ML/d)
The variable water quality
in Broughton Pass Weir
caused significant
treatment issues for the
Macarthur WFP.
Production was suspended
intermittently on 22 and
23 March.
Significant rain event in the
catchment areas upstream of
Broughton Pass Weir on Saturday
22 March 2014. Catchment was
affected by bushfire in October
2013 so there was insufficient
regrowth to prevent runoff
transporting nutrients and metals
into waterways
SCA and Sydney Water continuously monitored water
quality at the Broughton Pass & Pheasants Nest Weirs
and Upper Canal on real-time systems with regular
consultation & communication with the Macarthur and
Prospect WFPs. Appropriate adjustments were made
to the configuration of the raw water supply to
Broughton Pass Weir and the Upper Canal as required
to maintain the best available raw water supply for the
Macarthur & Prospect WFPs throughout this period.
02 Apr 14
Algae
Prospect WFP
A sample of raw water supplied to
Prospect WFP on 31/03/2014
recorded 2,002 ASU/mL. This was
part of an event monitoring
program prior to supplying from
Prospect Reservoir. Major Incident
trigger for Prospect WFP is 2,000
ASU/mL.
Sydney Water advised that
the plant did not express
any concern and were not
aware of any impact on
filter run times
Presence of diatoms which
contributed to 75% of the ASU.
Reviewed other related samples collected on the same
day and other samples from this site on previous and
following days and advised Sydney Water. Other
samples in March and April 2014 showed ASU around
30 – 150 ASU/mL. Prospect Reservoir was used for
supply from 29 March to 7 April with no treatment
issues and no customer complaints.
25 Apr 14
Algae
Kangaroo
Valley WFP
A sample of raw water supplied to
Kangaroo Valley WFP on
22/04/2014 recorded 7,862
ASU/mL. Major incident trigger is
5,000 ASU/mL
The dominant type of
algae found was
Cyanonephron which is
very small, not toxic, does
not produce taste and
odour or clog filters
Cyanonephron has been found in
large numbers at this time of year
in 2013 and 2012.
The WFP was contacted to ensure there was no impact
on plant processes. Monitoring of Bendeela Pondage
continued and the plant was contacted regularly to
ensure no impact on its ability to adequately treat
water.
