Annual Report on Drinking-water Quality 2012–2013
1. Key Findings
This report describes drinking-water quality for all registered community drinkingwater supplies that served populations of more than 100 people (the supplies) from
1 July 2012 to 30 June 2013 (the reporting period), representing 3,810,000 people (the
supply population). It describes how these supplies met the requirements of the
Drinking-water Standards for New Zealand (the Standards) and their progress towards
meeting the requirements of the Health Act 1956, as amended in 2007 (the Act).
To meet the overall requirements of the Standards, a supply must meet the
bacteriological, protozoal and chemical standards. Overall, 76.9 percent of New
Zealanders (2,930,000 people) on these supplies received drinking-water that met all
requirements of the Standards in the reporting period. This represents a 0.2 percentage
point increase in terms of supply population compared with the previous 1 July 2011 to
30 June 2012 reporting period.
Drinking-water achieving the bacteriological standards was received by 96.7 percent of
New Zealanders (3,684,000 people) on reported supplies during the period, compared
with 95.8 percent previously, an improvement of 0.9 percentage points. However
protozoal achievement decreased by 0.6 percentage points from 79.8 percent to 79.2
percent (3,017,000 people), and chemical achievement decreased by 0.4 percentage
points from 95.7 percent to 95.3 percent (3,631,000 people).
As expected, achievement against the Standards was generally highest in the large
supplies and lowest in the small supplies. The exception to this was the rate of chemical
achievement. While highest in large supplies, small supplies achieved better than
medium or minor supplies because they are not required to be assessed for chemical
contamination and so achieved by default.
Some of the duties of drinking-water suppliers (specified in sections 69S–69ZC of the
Act) take effect progressively over a number of years, having started on 1 July 2012 for
large supplies. As part of these provisions, water suppliers are required to prepare and
implement public health risk management plans. Overall, 45.1 percent of the supplies’
population have had plans implemented by 1 July 2013, while only 2.6 percent (100,000
people) are in supplies where plan drafting has not yet commenced.
Although small supplies generally do not require a public health risk management plan,
these are now implemented for 37.2 percent of their supplied population.
The overall supply population with an approved or implemented plan is now 93.1
percent, up from 49.9 percent in the previous period. While this change between periods
is greatest for large supplies (up 51.3 percentage points), there were improvements of
19.8 percentage points for medium supplies and 12.3 percentage points for minor
supplies.
During the 1 July 2012 to 30 June 2013 reporting period, a number of other actions
were carried out by water suppliers to meet the requirements of the Act.

Monitoring: Overall, supplies serving 95.4 percent of the population met the
monitoring requirements of the Standards. Achievement against the Escherichia
coli and chemical monitoring requirements of the Standards generally increased
with the size of the supply population, with 98.0 percent of large supply

populations and 78.7 percent of small supply populations receiving water that met
the monitoring requirements.

Adequacy of supply: Overall, supplies serving 98.7 percent of the population met
the requirement for adequacy of supply during the reporting period, including all
but one large supply, and all medium and minor supplies.

Source protection: Overall, supplies serving 99.7 percent of the population met this
requirement, including all large and medium supplies.

Records: Adequate records were maintained for supplies providing water to 99.8
percent of the population. All large and medium supplies met the records
requirement. Generally, small supplies are not required by the Act to keep records,
but supplies for 97.6 percent of the small supply population did so.

Complaints: Water suppliers investigated all of the complaints they received about
the drinking-water they supplied to the population, except for eight small supplies
serving 1300 people.

Remedial action: Almost all suppliers undertook immediate remedial action in
response to transgressions. Water suppliers did not take remedial action, when
necessary, in supplies serving 1.5 percent of the population.
By the end of the 1 July 2012 to 30 June 2013 reporting period, all size categories of
drinking-water supply had reported good progress towards meeting the legislative
requirements of the Act with the exception of monitoring and remedial actions. Water
suppliers are moving towards a more proactive approach to protect health. In general,
the larger suppliers have a greater level of compliance with their current requirements
than smaller categories of supplies.
While all but large or new drinking-water suppliers were not required to meet sections
69S to 69ZC of the Act within the reporting period, including the requirements
regarding monitoring, public health risk management plans, adequacy of supply and
source protection, most drinking-water suppliers did so.

Annual Report on Drinking-water Quality 2012–2013
2. Introduction
This report describes drinking-water quality for all registered community drinkingwater supplies that served populations of more than 100 people from 1 July 2012 to 30
June 2013 (the reporting period). It describes how drinking-water supplies met the
requirements of the Drinking-water Standards for New Zealand (the Standards)1 and
their progress towards meeting the requirements of the Act.
In addition, the report meets the requirement of the Act for the Director-General to
prepare and publish a report on drinking-water each year that includes information
about the quality of drinking-water, achievement against the Standards and compliance
of drinking-water suppliers with the Act.
In 2009, the requirement for each category of water supplier to comply with sections
69S to 69ZC of the Act (relating to drinking-water) was deferred for three years2. These
requirements come into force on staggered dates, beginning from 1 July 2012, as
follows:






new and large drinking-water supplies (more than 10,000 people) from 1 July 2012
medium drinking-water supplies (5001 to 10,000 people) from 1 July 2013
minor drinking-water supplies (501 to 5000 people) from 1 July 2014
small drinking-water supplies (101 to 500 people) from 1 July 2015
neighbourhood drinking-water supplies (25 to 100 people) from 1 July 2016
rural agricultural drinking-water supplies from 1 July 2016 or the date on which the
Standards are amended to include them, whichever is later.
The delay was to enable councils and other drinking-water suppliers to assess the
impact of the current economic climate on their operations. It also enabled councils to
consider the implications of the legislation on their Long Term Plans. It is the
Government’s expectation that water suppliers will continue to plan for compliance.
The changes did not affect the existing legal requirements for suppliers to keep records,
investigate complaints and take remedial action if they became aware of contamination
in their water supplies.
This report describes the methods used to gather the data and the caveats on the data and
its interpretation. The report then presents the findings regarding achievement against
the Standards and meeting the legislative requirements of the Act for each of the four
size categories of the drinking-water supplies. This is followed by a discussion and an
interpretation of the findings.

3. Methods
Information on drinking-water quality was obtained from drinking-water assessors
employed by district health board public health units, using questionnaires that sought
data relating to water supply quality, monitoring and management. The information was
collected at the level of the distribution zone, that is, the quality of water supplied to
consumers.
Two surveys were used to gather information from registered community drinkingwater supply zones that served populations of more than 100 people from 1 July 2012 to
30 June 2013. The first survey sought information about the microbiological and
chemical quality of the drinking-water, water treatment processes in use, the means used
to demonstrate achievement against the Standards, and the status of public health risk
management plans. This survey utilised the online Water Information New Zealand
(WINZ) database.
The second survey sought information relating to the management of drinking-water
supplies by drinking-water suppliers in terms of the requirements of the Act that will
eventually apply to water suppliers. An Excel spreadsheet was designed to collect the
information and was completed by drinking-water assessors in discussion with water
suppliers. The completed spreadsheets were returned to ESR for compilation and
analysis.
The following caveats apply for the purposes of data interpretation.

The report includes all community drinking-water supply distribution zones that
served more than 100 people, based on the information contained in the WINZ
database as at 30 June 2013.

The term ‘water supply’ in this report refers to a distribution zone, which is all or
part of a reticulated supply for which the water is expected to be of consistent
quality throughout. While smaller communities usually have a single distribution
zone, larger communities may have two or more. Size groupings of supplies are
therefore based upon the population served by each zone.

The population figures used in this report have been taken from the distribution
zone populations as recorded in WINZ. These figures are estimates and it is not
possible to determine the accuracy of the population figures. Furthermore, it is
likely that the WINZ population figures include residents-only in some zones, and
residents and non-residents in other zones.

Population figures in this report are, in general, rounded to the nearest thousand,
the exception being the small water supplies section where figures are rounded to
the nearest hundred.

It is likely that some of the community supplies are misclassified as self-supplies
and vice versa. Obvious apparent discrepancies (eg, distribution zones where the
name does not seem to fit the supply classification) have been queried with the
drinking-water assessors, but these are not always apparent.

For the purposes of the Standards’ achievement statistics, supplies that met the
Standards part-way through the survey period as a result of improving treatment
processes or monitoring programmes, have been marked as meeting requirements
for that aspect.
4
Annual Report on Drinking-water Quality 2012–2013

Overall adequacy of monitoring has been assessed on the basis of Escherichia coli
and chemicals. There is no requirement to monitor for protozoa in the Standards.

Protozoal achievement is assessed only at the treatment plant. Because this report is
distribution zone-based, a zone was determined to achieve the protozoal standards
if all treatment plants supplying the zone during the survey period achieved the
protozoal standards.

If a drinking-water supplier did not respond to the drinking-water assessors’
requests for information, then their zones would have been marked as noncompliant in this report. However, all suppliers responded for this report.

Acceptable answers to the questions about the legislative requirements included
‘not applicable’ (N/A) for source protection and complaints. The percentage of
supplies meeting the requirements of the legislation was calculated as the
percentage of zones that answered ‘yes’ or ‘N/A’.

Percentage figures used for achievement against the Standards and meeting the
requirements of the Act were calculated using the populations in the zones as
reported in the WINZ survey.

All percentage figures in this report are rounded. Accordingly, totals may not add
up to 100 percent.
Data quality assurance was built into all stages of the process, from data collection to
reporting. A number of checks, including integrity checks, peer reviewing and duplicate
analysis, were employed to ensure the data reported reflected the information collected
by the surveys. Additional checks of the data were made by the drinking-water
assessors and water suppliers who reviewed drafts of the zone-level data reported in the
appendices.
Overall, there was a higher level of quality assurance for information collected in the
WINZ survey assessing achievement against the Standards than for the survey assessing
achievement against the requirements of the Act. This is due to the robust design of the
WINZ survey module and its associated tools, providing almost real-time data integrity
checking.

4. Findings
This report covers 664 registered community drinking-water zones supplying water to
3,810,000 people in the 12-month reporting period of 1 July 2012 to 30 June 2013. Each
zone served 101 people or more.
Table 1 summarises achievement against the Standards for the current reporting period.
Table 2, later in the report, compares this achievement with overall results for the
previous (1 July 2011 to 30 June 2012) reporting period, while Tables 3 to 5 provide
similar comparisons at the bacteriological, protozoal and chemical level respectively.
The status of public health risk management plans is presented in Tables 6 to 8, while
Tables 9 to 11 summarise the extent to which water supplies met the legislative
requirements of the Act.
Detailed results of drinking-water quality monitoring, Standards’ achievement and the
meeting of legislative requirements for individual water supplies are shown in
Appendices 1 to 4.
4.1 Achievement against the drinking-water Standards
As the transition from the 2000 Standards to the 2005 Standards (Revised 2008) is
scheduled to take several years, and drinking-water suppliers may elect which of these
Standards they operate under, achievement is assessed against the Standard they have
chosen. Of the 664 registered community drinking-water supply zones serving more
than 100 people, 482 zones chose the 2005 Standards, 163 the 2000 Standards and 19
zones used neither. In terms of population served, those receiving water assessed
against the 2000 Standards have decreased to 174,000, from 225,000 people in the
previous period.
Microbiological achievement is based on two main microbiological reference
organisms, Escherichia coli and Cryptosporidium. Bacteriological achievement is
determined primarily using Escherichia coli monitoring, whereas protozoal
achievement is based on monitoring the effectiveness of the treatment processes used to
remove or disinfect Cryptosporidium.
Chemical achievement was assessed for those supplies that have been identified as
containing chemicals that require monitoring (known as Priority 2 (P2) determinands3).
A water supply is assessed as achieving if it has no P2 determinands, or if it has been
adequately monitored and that any P2 chemicals present are shown to be within
acceptable levels.
3Chemical
substances or determinands that are present in the water leaving the treatment plant or in the distribution
zone at potentially health-significant concentrations (usually greater than 50 percent of their maximum acceptable
value) are the only chemical determinands that must be monitored to meet the Standards. These chemicals are known
as Priority 2 (P2) determinands. Where a supply has no P2 assignation, because the supply has not been assessed for
that chemical, the safety of the supply with respect to chemical determinands is uncertain. The relative softness of
New Zealand’s water sources results in a general tendency for its drinking-waters to dissolve metals from plumbing
fittings, a property termed plumbosolvency. All drinking-waters are designated as plumbosolvent unless the water
supplier can show they are not. Metals arising from plumbosolvency do not have to be monitored, provided the public
is advised to flush their taps before drawing water for consumption.

4.2 Compliance with the Act
The following four sections consider compliance with the Act for drinking-water
supplies during the reporting period of 1 July 2012 to 30 June 2013, according to the
size of the zones: large (more than 10,000 people), medium (5001–10,000), minor
(501–5000) and small (101 to 500).
4.2.1 Large water supplies (more than 10,000 people)
In New Zealand, large water supplies provided drinking-water to 2,989,000 people in 74
large distribution zones during the reporting period of 1 July 2012 to 30 June 2013. This
is 79 percent of the people covered by this report.
a. Meeting the drinking-water Standards
From 1 July 2012, large drinking-water suppliers must take all practicable steps to
comply with the Standards.
Attainment: For people receiving water from large supplies:
 86.7% received water fully meeting the standards (2,591,000 people in 59 zones)
 99.0% received water meeting the bacteriological standards (2,960,000 people in 72
zones)
 88.7% received water meeting the protozoal standards (2,653,000 people in 61
zones)
 97.1% received water meeting the chemical standards (2,902,000 people in 70
zones).
b. Monitoring requirements in the Standards
From 1 July 2012, large drinking-water suppliers must meet the monitoring
requirements in the Standards.
Attainment: For people receiving water from large supplies:
 98.0% received water that fully met monitoring requirements (2,930,000 people in
70 zones)
 99.0% received water with adequate Escherichia coli monitoring (2,960,000 people
in 72 zones)
 99.0% received water with adequate chemical monitoring (2,959,000 people in 72
zones).
c. Public Health Risk Management Plans
From 1 July 2012, large drinking-water suppliers must provide public health risk
management plans for their water supplies. The plan must be submitted to a drinkingwater assessor for approval before 1 July 2013 and the supplier must begin to
implement the plan within one month of it being approved.
Attainment: For people receiving water from large supplies:
 all received water where the plan had at least been submitted for approval
 0.4% received water with a plan submitted for approval (13,000 people, 1 zone)
 54.4% received water with approved but not yet implemented plans (1,626,000
people in 32 zones)
 45.2% received water where plan implementation had commenced (1,350,000 people
in 41 zones)
 for large zones, an approved or implemented plan meets the legislative requirements
8
Annual Report on Drinking-water Quality 2012–2013
for this first year. This covers 99.6% of those receiving water (2,976,000 people in
73 zones).
d. Adequacy of supply
From 1 July 2012, large drinking-water suppliers must take all practicable steps to
ensure an adequate supply of drinking-water is provided to each point of supply.
Interruptions may occur for planned maintenance, improvements or for emergency
repairs. However, if the interruptions are likely to exceed eight hours, the water supplier
needs to have prior approval from the medical officer of health and to have taken all
practicable steps to warn affected people. If the supply is interrupted in an emergency,
the supplier has up to 24 hours to inform the medical officer of health.
Attainment: For people receiving water from large supplies:
 98.4% received water with adequacy of supply (2,943,000 people in 73 zones).
e. Source protection
From 1 July 2012, large drinking-water suppliers must take steps to protect their water
sources from contamination and pollution. These steps may include making submissions
on district plans, resource consent applications or sanitary service assessments. Source
protection may also include contributing to catchment management.
Attainment: For people receiving water from large supplies:
 100% received water with source protection activities undertaken (2,989,000 people
in 74 zones).
f. Records
From 1 July 2008, large drinking-water suppliers must keep records of their water
supplies to enable a drinking-water assessor to ascertain whether the water supplier is
meeting the requirements of the Act.
Attainment: For people receiving water from large supplies:
 100% received water with adequate records kept (2,989,000 people in 74 zones).
g. Complaints
From 1 July 2008, large drinking-water suppliers must record and investigate
complaints about their water supplies.
Attainment: For people receiving water from large supplies:
 100% received water with all complaints recorded and investigated (2,989,000
people in 74 zones).
h. Remedial steps
From 1 July 2008, large drinking-water suppliers must take remedial action if their
water supply does not meet the Standards.
Attainment: For people receiving water from large supplies:
 99.4% received water with adequate remedial steps taken (2,972,000 people in 73
zones)
 0.6% received water with inadequate or no remedial steps taken (17,000 people in
one zone).

4.2.2 Medium water supplies (5001 to 10,000 people)
In New Zealand, medium water supplies provided drinking-water to 264,000 people in
36 medium distribution zones during the reporting period of 1 July 2012 to 30 June
2013. This is seven percent of the people covered by this report.
a. Meeting the drinking-water Standards
From 1 July 2013, medium drinking-water suppliers will need to take all practicable
steps to comply with the Standards.
Attainment: For people receiving water from medium supplies:

5. Interpretation and discussion
5.1 Introduction
The Act aims to protect public health by ensuring that communities are provided with a
safe, wholesome and adequate supply of drinking-water. Using risk management
concepts to do this, it promotes proactive measures using public health risk management
plans and appropriate monitoring of drinking-water quality. This monitoring checks the
extent to which quality remains within maximum acceptable values and, by implication,
the effectiveness of the public health risk management plans.
This section discusses bacteriological, protozoal and chemical achievement against the
Standards, progress in public health risk management plan preparation and use, and the
public health significance of these findings. The discussion considers achievement in
terms of size of supply. The extent to which other requirements of the Act were met
during the reporting period (1 July 2012 to 30 June 2013) are also discussed
individually, with the category of supply determining when various aspects of the Act
come into force.
In considering the public health significance of maximum acceptable value exceedences
discovered during monitoring, greater discussion is provided for chemical than
microbiological results. This is because concentrations of the chemicals of concern were
measured and the quantitative toxicological basis for their maximum acceptable values
is usually known. Microbiological achievement uses the detection of indicator
organisms combined with assessing barriers to contamination, rather than measuring the
concentrations of disease-causing microorganisms (pathogens) in the water.
5.2 Overall achievement against the Standards
Overall achievement against the Standards requires a water supply to meet the
requirements for bacteriological, protozoal and chemical achievement. During the
current reporting period (1 July 2012 to 30 June 2013), 76.9 percent of the population in
registered community drinking-water supplies serving more than 100 people received
drinking-water from fully compliant water supplies. This is marginally improved upon
the previous period (1 July 2011 to 30 June 2012), when 76.7 percent received water
from fully compliant water supplies. This represents an improvement of 10,000 people.
Table 2 shows the proportions of the population that received drinking-water from fully
achieving supplies during the current and previous reporting periods.

* A positive change represents an improvement in achievement.
Overall, in terms of supply population, bacteriological and chemical achievement were
achieved to the greatest degree, followed by protozoal achievement. (Note that the high
level of chemical achievement for small supplies arises by default, because P2
determinands are usually assigned only to zones with populations exceeding 500.)
Compared with the previous period, bacteriological achievement in terms of population
rate increased by 0.9 percentage points (36,400 people), while protozoal achievement
decreased by 0.6 percentage points (21,700 people) and chemical achievement
decreased by 0.4 percentage points (13,500 people).
The New Zealand Drinking-water Standards lay out how to assess the quality of
drinking-water and specify the water quality standards that all drinking-water supplies
must achieve. It is possible to fail to meet the Standards due to technical failures4 such
as inadequate sampling5, or because of failures that are a direct public health concern6,
such as exceeding the maximum acceptable value of a determinand such as Escherichia
coli.
Exceedence of a microbiological maximum acceptable value is generally of greater
concern than the exceedence of a chemical maximum acceptable value because of the
timescales over which their adverse effects are likely to be experienced. Pathogens can
cause illness rapidly, following a single contamination event. Chemicals, unless present
at extraordinarily high concentrations, will generally have adverse effects only after
decades of exposure. For these reasons, immediate remedial action is more important in
response to microbiological than chemical exceedences.
The 0.9 percentage point improvement in bacteriological achievement arose despite
mixed contributions from associated factors. In terms of reported population, there was:

a 1.2 percentage point decrease in people receiving water with excessive
transgressions

and a 0.4 percentage point decrease in people receiving water for which there was
inadequate corrective action following a transgression
4Failure
to achieve for protozoal can only be due to a technical failure, as routine measurement of protozoa in treated
water is currently impracticable.
5Inadequate number of samples, sampled on too few days of the week and/or sampling exceeded the maximum
number of days between samples.
6Reasons for bacteriological failure of direct public health concern include excessive transgressions, inadequate
corrective action following a transgression of the maximum acceptable value and/or no monitoring.


but a 0.2 percentage point increase in people receiving water from inadequately
monitored supplies.
It was noted that, as with the previous period, all supplies used Ministry of Health
recognised laboratories for Escherichia coli monitoring.
The first two of these reasons for non-achievement, ‘excessive transgressions’ and
‘inadequate corrective action’, potentially put public health at risk. ‘Inadequate
monitoring’, where sampling is not carried out in accordance with the Standards, is a
technical non-achievement and not a direct public health concern. This technical failure
figure excludes supplies with excessive bacteriological transgressions or inadequate
corrective actions.
5.3 Bacteriological achievement against the Standards
During the reporting period (1 July 2012 to 30 June 2013), 96.7 percent (3,684,000
people) of the population in small to large community drinking-water supplies was
supplied with drinking-water that met the bacteriological requirements of the Standards
(Table 1). Percentage achievement increased with the size of the population served by a
supply. Bacteriological achievement on a population basis was achieved for 99.0
percent of people in large zones, 94.6 percent in medium zones, 87.5 percent in minor
zones and 72.2 percent in small zones. This may reflect the increasing per capita cost of
effective bacteriological treatment as the community population size decreases, or the
progressive introduction of the requirements of the Act by supply size.

Table 3 shows that bacteriological achievement has improved in all zone sizes except

served) and small (3.8 percent).
Approximately 3.3 percent (125,000 people) of the reported population was supplied
with drinking-water that failed to achieve bacteriologically with the Standards7. The
causes of non-achievement and the number of people affected were:

1.3 percent (48,000 people) of the reported population were served by supplies
with excessive numbers of Escherichia coli transgressions
7Some
people supplied with water that failed bacteriologically against the Standards fell into more than one of the
non-achieving categories.
18
Annual Report on Drinking-water Quality 2012–2013

2.0 percent (78,000 people) of the population were served by supplies where
Escherichia coli were inadequately monitored

0.3 percent (10,000 people) of the population were served by supplies where
Escherichia coli monitoring was not carried out

0.1 percent (2000 people) of the population were served by supplies in which
transgressions occurred that were not followed up by immediate corrective action.
Compared with the previous reporting period (1 July 2011 to 30 June 2012), the largest
changes in affected populations in this list represented improvements: 44,000 fewer
people received water with excessive numbers of Escherichia coli transgressions and
14,000 fewer people were served by supplies in which transgressions occurred that were
not followed up by immediate corrective action.
5.3.1 Public health significance of exceedences
The presence of Escherichia coli in water indicates that the water has been
contaminated with faeces. This may be the result of the raw water being contaminated
and the water being inadequately treated, or it may result from contamination of the
water, after treatment, during distribution to the community. In either case, although
Escherichia coli itself may or may not present a threat to health, its presence means that
pathogens also present in the faeces could be present in the water. Although the
concentrations of these pathogenic organisms are not monitored, their possible presence
must be assumed and consequently the detection of Escherichia coli in the water must
be regarded as a serious risk to public health.
As well as indicating a risk to public health, the detection of Escherichia coli shows that
there has been a failure in the barriers between contaminants and the community.
Consequently, all Escherichia coli transgressions must be immediately investigated and
corrective action implemented. Depending on the result of the investigation,
modification of the supply’s public health risk management plan may also be needed.
During the reporting period (1 July 2012 to 30 June 2013), 0.1 percent of the population
(2000 people) was served by 13 small supply zones in which Escherichia coli
transgressions occurred that were not appropriately followed up by immediate
corrective action.
The failure to take appropriate corrective action immediately following Escherichia coli
transgressions is a serious cause of concern because of the public health consequences
that could follow if the failure coincided with raised pathogen concentrations in the
source water. Failure to reduce this risk by increased disinfection, or by taking
appropriate steps to reduce the hazard (ie, closing or changing the supply) or exposure
(ie, recommending that people boil all drinking-water), increases the likelihood of
waterborne disease. Inadequate corrective action indicates that the water supplier has
either failed to recognise this issue or to accept that it poses a potentially serious health
risk.
5.3.2 Darfield outbreak
During the reporting period, an outbreak of waterborne gastroenteritis occurred at
Darfield in the Selwyn District of Canterbury, a supply serving 3300 people. Routine
monitoring, in accordance with the bacteriological Standards, identified the presence of
faecal coliforms and Escherichia coli in the drinking-water. A boil water notice was
Annual Report on Drinking-water Quality 2012–2013
19
issued and improvements in the chlorination process were made. Despite these actions,
an outbreak ensued with 29 cases positive for Campylobacter spp. and another 109
cases meeting the case definition for probable gastroenteritis8. The supply is not yet
required to have a Public Health Risk Management Plan. However, the local public
health unit is keen for the supplier to adopt a multi-barrier approach consistent with the
Act, as this would prevent incidents such as these in the future9.

5.4 Protozoal achievement against the Standards
During the reporting period (1 July 2012 to 30 June 2013), 79.2 percent (3,017,000
people) of the population in small to large community drinking-water supplies was
supplied with drinking-water that met the protozoal requirements of the Standards
(Table 1). There is a clear trend of protozoal achievement against the Standards
improving as supply population size increases: protozoal achievement on a population
basis was achieved for 88.7 percent of people in large zones, 56.9 percent in medium
zones, 41.0 percent in minor zones and 24.1 percent in small zones.
Protozoal achievement between reporting years is summarised in Table 4. Compared
with the previous period (1 July 2011 to 30 June 2012), a decrease in overall protozoal
achievement on a population-served basis occurred.
For large supplies, ten failed protozoal achievement for both the current and previous
periods, two failed only the previous period, while a different three failed only this
period. This gave a net decrease in large supply achievement of 41,000 people. This
decrease arose from technical failures in providing or monitoring appropriate plant
processes, since protozoa are not monitored for directly.
The large supply decrease in protozoa achievement leads to an overall decrease for all
supplies in terms of population served. This masks an improvement for all other supply
sizes, including a 10,000 people improvement in medium supplies.

Protozoal non-achievement does not necessarily mean that pathogenic protozoa
(Giardia sp. and Cryptosporidium sp.) were present in the water. Water suppliers are
not required to monitor the water for pathogenic protozoa. Instead, protozoal
achievement is based on the likelihood that the treatment processes in operation will
adequately protect the community if pathogenic protozoa were present in the source. To
achieve this, the water supplier must do two things. Firstly, they must have treatment
processes in operation that the Standards state can remove or inactivate an adequate
percentage of any protozoa present in the raw water. Secondly, the water supplier must
be able to show that they are operating the treatment processes sufficiently to meet the
target percentage removal.
The trend of decreasing protozoal achievement against decreasing supply size is
possibly a reflection of the high cost of effective protozoal treatment, which is less able
to be borne by smaller communities. It is also possible that the operators of treatment
plants supplying smaller communities do not have the same level of expertise as those
operating larger systems.

5.5 Chemical achievement against the Standards
During the reporting period (1 July 2012 to 30 June 2013), 95.3 percent (3,631,000
people) of the population in small to large community drinking-water supplies was
supplied with drinking-water that met the chemical requirements of the Standards
(Table 1), while 4.7 percent (178,000 people) received water that did not achieve the
Standards.
Chemical determinands are not regularly monitored in all supplies, but are assigned to
specific supplies where treatment or water characteristics indicate levels may approach
health limits.
During this period, 163 distribution zones supplying 61 percent (2,333,000 people) of
the report population were assigned chemical determinands. For these people, the
chemical Standards were achieved for 92.4 percent (2,154,000 people) and not achieved
for 7.6 percent (178,000 people).

5.5.1 Fluoride
Fluoride was added to the drinking-water received by 56 percent of the reported
population (2,123,000 people) in 104 zones. (Note that these figures exclude 143,000
people in Hamilton, as fluoridation was discontinued during the reporting period.)
No fluoride exceedences were found in water leaving any fluoridating treatment plant.
Monitoring of fluoride was adequate for water supplied to 92 zones (2,059,000 people),
but inadequate at seven treatment plants supplying 12 zones (64,000 people). At all but
one of these treatment plants, at least 90 percent of samples required were taken. No
fluoride exceedences were found in water leaving any fluoridating treatment plant.
It is cost-effective to fluoridate zones serving more than 1000 people (Wright et al
199910), and 3,661,000 of the reported population are in this size grouping. Of these
people, 58 percent or 2,115,000 people and 33 percent (88) of zones were fluoridated
throughout the reporting period. For the other 16 fluoridated zones of fewer than 1000
people, 14 received their water from a treatment plant serving a total population of 1000
or more.

5.5.2 Other chemical determinands
a. Maximum acceptable value exceedences
Drinking-water supplies to around 124,000 people (25 zones) exceeded the maximum
acceptable values for at least one chemical during the reporting period (1 July 2012 to
30 June 2013). All except two zones were in separate communities. Zones with
exceedences were located in both islands, but with the majority being in the North
Island. The chemicals for which the maximum acceptable values were exceeded were:
arsenic, boron, dichloroacetic acid, manganese, nitrate, total haloacetic acids and total
trihalomethanes. All except one of the eight zones with arsenic exceedences were
located near Lake Taupo or in the Bay of Plenty. The exception was in an area of the
North Island with metal-containing minerals.
b. Frequency and extent of maximum acceptable value exceedences
The frequencies at which maximum acceptable values were exceeded in monitoring
samples ranged from seldom (one of 25 samples), to a zone in which a chemical almost
always exceeded its maximum acceptable value (11 of 13 samples). The median
frequency was 17 percent of samples. The highest chemical concentrations reported
ranged from concentrations that barely exceeded the maximum acceptable value to
concentrations five times the maximum acceptable value. The great majority of
exceedences were less than twice the maximum acceptable value. High frequencies and
large exceedences did not occur together.
c. Public health significance of exceedences
The greatest exceedence of a maximum acceptable value was for manganese. In this
zone, the manganese concentration exceeded the maximum acceptable value in 27
percent of monitoring samples (16 of 59), although in 61 percent of samples the
manganese concentration was less than 50 percent of the maximum acceptable value.
Such cases are unlikely to be of public health significance. Maximum acceptable values
are calculated to provide satisfactory protection against adverse health effects for a
lifetime (70 years) of drinking-water consumption. Consequently, relatively infrequent
exceedences of the maximum acceptable concentration are unlikely to result in an
unsafe level of exposure.
In the one zone, serving 1300 people, in which boron exceeded its maximum acceptable
value, the frequency of exceedence dropped from approximately 84 percent last year to
7 percent this year following actions to address the problem. At this frequency of
exceedance, the boron concentration in this supply is not a public health concern. The
most recent edition of the World Health Organization’s Guidelines for Drinking-water
Quality (2011)11 has increased the boron guideline to 2.4 mg/L, a value well above the
highest concentration found in this zone.
The frequencies of exceedence reported for arsenic ranged from low (17 percent of
samples) to high (85 percent of samples). In two zones arsenic exceeded its maximum
acceptable value in more than 75 percent of samples. Both zones reported arsenic
concentrations in excess of twice the maximum acceptable value. Exceedences of
arsenic’s maximum acceptable values are of greater public health significance than the
exceedences by other chemicals of their maximum acceptable values. The level of

Annual Report on Drinking-water Quality 2012–2013
23
acceptable risk used to set the maximum acceptable value for most carcinogens is 1 in
100,000. For arsenic however, the maximum acceptable value of 0.01 mg/L cannot be
lowered, because of analytical and treatment limitations. This equates to a level of risk
of 1 in 1700 (the Standards).
In two zones nitrate was reported to exceed its maximum acceptable value. The
frequencies of exceedence were low (4 and 13 percent of samples) and the exceedences
of the maximum acceptable value were small (15 and 5 percent respectively). These
exceedences do not represent a public health risk, even for infants, who are the most
vulnerable portion of the population. The World Health Organization’s Guidelines for
Drinking-water Quality (2011)11 notes that waters with nitrate concentrations up to
twice the maximum acceptable value are safe for infants, provided the water is
microbiologically safe. Both zones met the bacteriological requirements of the
Standards.
The remaining group of chemicals found to have exceeded their maximum acceptable
values are trihalomethanes and haloacetic acids, both of which are possible human
carcinogens. While absent in the source water, they can occur as disinfection byproducts from the chlorination process. Despite their possible carcinogenicity, the
World Health Organization11 advises that it is of ‘paramount importance’ that the
efficacy of disinfection is not compromised in trying to minimise their formation.
Trihalomethanes or haloacetic acids exceeded their maximum acceptable values in 13
zones serving 79,000 people. Frequencies of exceedence ranged from 4 to 75 percent,
with the frequency being 17 percent or less in most zones (10 of 13). Maximum
acceptable values were exceeded by no more than 50 percent in 9 of 13 zones, but in
two zones (2300 people) the concentrations of haloacetic acids were reported to be over
twice the maximum acceptable value. Like most carcinogens, their maximum
acceptable value is set at a level of risk of 1 in 100,000, a much lower value than that
for arsenic.
d. Monitoring
Unsatisfactory monitoring remains a major reason for non-achievement against the
chemical criteria of the Standards. Without this information, the water supplier cannot
make well-informed decisions about the actions to take to meet the Standards, and the
health significance of chemicals assigned to a distribution zone cannot be readily
assessed.

Annual Report on Drinking-water Quality 2012–2013
5.6 Status of public health risk management plans
Monitoring water quality alone is not a satisfactory approach to water supply
management. In most instances test results will arrive too late to prevent contaminated
water reaching a community. The Act requires water suppliers to move beyond reliance
on monitoring only. Public health risk management plans are fundamental to the water
supplier being able to produce safe water and having confidence that the water is safe at
times when monitoring samples are not available to confirm its quality.
Preparing a public health risk management plan requires a water supplier to review the
whole of their water supply from the raw water (and possible contaminant sources),
through the treatment processes, to the pipe network that carries the water out into the
community. During this review, possible causes of contamination are identified and
measures put in place to reduce the likelihood of these events happening. The plan also
states what remedial actions need to be taken should a contamination event occur,
despite the preventive measures.
Table 6 shows progress with developing and implementing public health risk
management plans for the categories of supply covered by this report.
Overall, zones serving 45.1 percent of the reported population (40 percent of zones)
have begun to implement their public health risk management plans. Drinking-water
suppliers serving a further 52.3 percent of the population (41 percent of zones) were
preparing their plans prior to implementation. Public health risk management plans for
all large zones except one have been approved and are either being implemented or
about to be. The rate of development and implementation of the plans decreased with
reducing population size. For example, suppliers for 25.4 percent of people served by
small zones had not started preparing their public health risk management plans.
However, small supplies have longer to comply and many do not have to comply unless
they opt to use section 10 of the Standards 2005 (revised 2008) or are required to under
section 69ZA of the Act.

5.7 Meeting legislative requirements
5.7.1 Overview
The Act places some specific duties, considered key to protecting the safety of drinkingwater supplies, on water suppliers. Some of these are contained in the Standards (such
as monitoring) or should be included in public health risk management plans (such as
source protection, keeping records and remedial actions). Others, such as handling
complaints, may not so evidently appear in other tools used in water supply
management.
Zones other than large zones were not required to meet monitoring, adequacy of supply,
or source protection, during the reporting period.
Table 9 summarises the extent to which supplies have met these key requirements, then
Table 10 presents this as a function of supply size.

# Small suppliers do not have to keep records under section 69ZD(1) of the Act.
Supply zone size: Large: Over 10,000
Medium: 5001–10,000
Minor: 501–5000
Small: 101–500.
Within the time frame of this report, only large drinking-water suppliers were expected
to meet the requirements of sections 69S to 69ZC of the Act. This includes the
requirements regarding monitoring, adequacy of supply, source protection and public
health risk management plans. However, most suppliers met these requirements.
Overall, water suppliers are meeting their current requirements and many are meeting
their future requirements. There is a tendency for fewer smaller drinking-water suppliers
Annual Report on Drinking-water Quality 2012–2013
29
to have met their current requirements under the Act than the larger drinking-water
suppliers, but smaller suppliers have several more years before compliance is required.
Many drinking-water suppliers already meet the requirements of the aspects of the Act
that are being phased in and many others are making progress towards this achievement.
5.7.2 Requirements by section of the Act
a. Monitoring requirements (section 69Y)
Sole reliance on monitoring is an unsatisfactory basis for managing drinking-water
quality. However, the Act requires large water suppliers, and will require other water
suppliers, to monitor water quality (as required in the Standards) because it is still a key
component in managing drinking-water supplies. It is necessary as a check that the
public health risk management plan is operating satisfactorily, and to indicate whether
remedial action is required. Further, it allows the water supplier to determine whether
the drinking-water quality meets that required by the Standards.
Overall, zones serving 95.4 percent of the population met the monitoring requirements.
Percentage compliance increased with the size of the population served by a supply.
Monitoring requirements in the reporting period (1 July 2012 to 30 June 2013) were met
for 98.0 percent of the population served by large supplies, 86.6 percent served by
medium supplies, 86.4 percent by minor supplies and 78.7 percent by small supplies.
b. Adequacy of supply (section 69S)
Insanitary conditions can arise when a community is without water, and consumers can
seek other, possibly unsafe, sources of water. To avoid such eventualities, drinkingwater suppliers will be required to take all practicable steps to ensure the adequacy of
supply and in the event of an interruption, planned or otherwise, to take appropriate
action.
Overall, zones serving 98.7 percent of the population met this requirement during the
reporting period. All except one large zone, plus all medium and minor zones, serving a
total population of 3,681,000 people, met the adequacy of supply requirements, while
zones serving 97.8 percent of the population in small supplies met this requirement.
c. Source protection (section 69U)
The protection of the quality of source waters is probably the most important
component of the multi-barrier approach to drinking-water supply management
encouraged by the Standards. Protection of source waters reduces the numbers and
concentrations of contaminants that the water treatment system has to deal with.
Further, the consequences for public health in the event of treatment failure will be
reduced.
Overall, zones serving 99.7 percent of the population met this requirement. All large
and medium zones, serving a total population of 3,254,000 people, met the source
protection requirements, while zones serving 98.6 percent of the population in minor
zones and 95.7 percent in small supplies also met this requirement.
30
Annual Report on Drinking-water Quality 2012–2013
d. Records (section 69ZD)
The maintenance of records assists water suppliers and drinking-water assessors in
determining whether a supply meets the requirements of the Act and complies with the
Standards. It also ensures that people unfamiliar with a supply, such as a new employee,
are better informed about the way the supply should be operated and what operational
parameters have been typical. In the event of a waterborne disease outbreak or other
incident resulting from system failure, well-kept records may assist in understanding
what has gone wrong and how this could be prevented in the future.
Overall, adequate records were maintained for distribution zones supplying 99.8 percent
of the population. All large and medium zones met the records requirement, along with
those serving 98.6 percent of people in minor zones and 97.6 percent in small zones12.
e. Complaints (section 69ZE)
Complaints about drinking-water quality most often relate to the aesthetic properties of
the water (taste, odour and appearance). In some cases, our senses of taste and smell are
better able to identify a problem than instrumentation. Complaints need to be
investigated, because they potentially inform the water supplier of a problem about
which they may not otherwise be aware. Consumer concerns about the taste and odour
of water, if sufficiently severe, may lead to the consumer seeking another source of
drinking-water. While the alternate source may not have the aesthetic problems
associated with the first, it may contain contaminants that cannot be detected by our
senses.
Overall, water suppliers investigated almost all of the complaints they received about
the drinking-water they supplied to the population. The only exceptions were for eight
small zones serving a total of 1300 people altogether.
f. Remedial steps (section 69ZF)
The Act requires drinking-water suppliers to take remedial actions in the event that
monitoring reveals contamination of the water and that the Standards are breached.
Prompt action is required when the contaminants are microbiological, because
pathogens can rapidly cause disease. Although the Standards set out specific remedial
actions for particular situations, the absence of instructions for a specific situation
should not prevent drinking-water suppliers from seeking a way of remedying a fault
they have identified in their system, which may adversely affect the safety of the supply.
Almost all suppliers undertook remedial actions in response to transgressions. Water
suppliers did not take remedial action, when necessary, in 31 zones serving 1.5 percent
of the population (59,000 people). Of these zones, one was large (17,000 people) and
three medium (totalling 19,000 people.)
