INTRODUCTION-PURPOSES AND AIMS
An application is to be made for a residential development within the grounds
of the former St. David’s House Hospital in Llanfaes, Brecon. It is proposed to
build six link houses, four detached houses and convert an existing building into
apartments. Because it is classed as a large development a pre-planning
consultation process (ref. 19/17103/STATPA) is necessary
The National Park Authority (who are the planning authority) have advised the
developers that a preliminary risk assessment (Phase 1 report) needs to be
submitted as part of the pre-planning consultation process. They have received
advice from Powys C.C. Environmental Health about the potential presence of
land contamination due to the former use of the site. Rhondda Geotechnical
Services have been engaged to produce this desk top study known as a Phase 1
Contaminated Land Report.
The report will follow the guidelines set out in the document Development of
Land Affected by Contamination: A Guide for Developers (Version 3). This was
produced by the Welsh Land Contamination Working Group in 2017. In
particular the methodology set out in appendix B with the check list for Phase 1
will be followed. The contaminated land exposure assessment (henceforth
CLEA) produced by The Environment Agency will be used in the conceptual
model, particularly in regard to the source-pathway-receptor concept for
pollutant linkages. The entire project will be guided by the 2004 Defra/E.A.
document CLR11 (Model Procedures for the Management of Land
Contamination).
The current definition of contaminated land is “any land which appears to the
local authority in whose area it is situated in to be in such a condition, by reason
of substances in or under the ground that
a. Significant harm is being caused, or there is a significant possibility of such
harm being caused OR
b. Pollution of controlled waters is being, or is likely to be caused”
Section 78A Part 2A Environmental Protection Act
This act also requires that a risk based approach should be used for assessing
the contamination status of a site. For a site to be designated as contaminated
it must be shown that the site is not fit for its current, or intended use.
Statutory guidance states that a two stage approach should be adopted for the
assessment of contaminated land.
1. Identification of potential pollution linkages
2. Assessment of the risk to receptors
The first stage (The Phase 1 report) is a qualitative assessment of the plausible
pollution linkages that exist or may exist on site. This involves the development
of a site conceptual model. This may then be refined in Phase 2 after an
intrusive investigation, followed by laboratory testing of samples obtained. A
Phase 2 is only carried out if the Phase 1 deems it necessary.

2. SITE DESCRIPTION
The site is centred on grid reference 303730, 228075 and is at an average
elevation of approximately 148m. A.O.D. The site is a triangular plot covering
approximately 0.87 Ha. The former hospital buildings cover approximately a
quarter of the site, with the remainder comprising of lawned grounds with some
mature trees. The site is bounded on two sides by residential developments. On
the third, southwest side a field separates the site from the A40 Brecon Bypass.
There are no surface watercourses. The site location and site boundary can be
seen overleaf in Figures 1 and 2 with an aerial photograph of the site in Figure
3.

3. SITE WALKOVER
The W.L.G.A./ N.R.W. template states that a site walkover should form part of
the Phase 1. The purpose of a site walkover is to identify areas of possible
contamination. This is really aimed at larger industrial sites with mixed land use.
The former hospital buildings are all intact and in relatively good condition.
Presumably prior to demolition the buildings will be subject to a thorough
asbestos survey, and any demolition work will then be informed by the results
of the survey. One feature that did stand out was the fuel oil storage area. The
tanks were well bunded, and there were no apparent signs of any leakage. They
are standing on a concrete slab with plants growing in accumulated material. As
with the possible risk from asbestos, the tanks need to be removed by
experienced contractors. At present there are no signs that they have been a
possible source of contamination. In fact the opposite is true, they appear to be
structurally sound, and have been well managed in the past.
The northern part of the site is a steeply sloping area with mature trees, it does
not form part of the proposed development. A general view of the site is shown
overleaf in Figure 3B and a view of one of the two fuel oil tanks is shown in Figure
3C.

4. SITE HISTORY
In order to gain a thorough understanding of the history of the site a
comprehensive collection of historical Ordnance Survey maps was purchased
from Groundsure. These were at both 1:2500 and 1:10560 scales (later maps are
at 1:10,000). Obviously the larger scale maps are preferable for a desk study but
sometimes (as in this case) a large gap in dates means it is necessary to fall back
on the smaller scale maps. Another reason for using the smaller scale maps is
that they can provide a broader contextual setting for the site. In terms of the
site itself, there has been virtually no change from the earliest (1889) map to the
present day. Residential developments in the surrounding area have gradually
encroached on the site, but the building itself occupies a virtually identical
footprint as it did in 1889.
1889- Figure 4 is a section of the oldest available map. The building is labelled
Brecknock Union Workhouse, and sits in farmland south of Llanfaes which has
developed along the main road leading into Brecon from the west.
1904- There is a slight change in the grounds around the workhouse. The
coniferous trees lining the drive leading to the building are no longer shown. In
the surrounding area a large steam laundry is labelled 200m north of the site on
the main street of Llanfaes.
1948- Figure 6 is a smaller scale map (1:10,560) from 1948. There is a
development immediately north of the site. It is unlabelled, but it is highly likely
it is a military barracks. The map was published just after the Second World War
at a very sensitive time and this is the probable reason the buildings are not
identified. The site itself is labelled Brecknock P.A. Institute.
1963- The barracks? have gone and extensive residential housing has been built
south of the main road in Llanfaes. There is also a garage shown on the main
road. Allotment gardens separate the housing from the site, which is now
labelled St. David’s Hospital. Llanfaes County Primary School has been built to
the northwest of the site.
1986- The most recent large scale map show the A40/A470 Brecon Bypass has
been constructed just south of the site. Two blocks of flats have been built
adjacent to the site’s northern boundary. Since the map’s publication there have
been further residential development just east of the site at St. David’s Park.
This can be seen in the aerial photograph in Figure3A.
From further research about the site it seems that the site became a hospital
in the 1960’s and was a geriatric Hospital, with no surgery carried out. It was
closed in the early 1990’s and its most recent use was as a Hall of Residence for
the nearby Christ College, a private school.

5. GEOLOGY
The geology under this (or any other) site can be divided into two components.
The bedrock and the superficial deposits (including Made Ground) overlying it.
For a contaminated land study the superficial deposits are the more important
of the two as they are the shallowest. This means they are the most likely to be
impacted by contamination, and indeed with Made Ground, can themselves be
a source of contamination.
A Geoinsight report was purchased to obtain geological information for the
Phase 1. It is included in full in Appendix A. The Brecon area has only been
mapped at 1:50,000 scale. Areas that benefit from larger scale geological
mapping usually have mineral deposits of economic significance. Apart from
several locations of historical quarrying for building stone, there are no
extractive industries within a kilometre radius of the site.
Superficial DepositsFigure 10 is an extract from the Geoinsight report map (p18) showing the
distribution of the (natural) superficial deposits. The previous sections in the
report say there is no Made Ground or Fill within 450m of the site. The land
directly beneath the site is described as (1-pale green on the map) Devensian
glacial deposits. Devensian Till is the material formerly known as Boulder Clay.
This is a poorly sorted mixture of sediments of glacial origin, ranging in grain size
from clay to cobble/boulder as the old name suggests. It is generally relatively
impermeable, although there can be sandier, more permeable horizons and
water migration along fissures. Just to the north of the site the pink areas
labelled 2,5 and 6 are Fluvioglacial sands and gravels, which would be expected
to be much more permeable
Solid (Bedrock) Geology:The bedrock beneath the site is of Devonian Age, part of the sequence known
as the Old Red Sandstone. Specifically the bedrock underlying the site is the St.
Maughans Formation. This is a sequence of predominantly argillaceous rocks
with interbedded, subordinate sandstones. Since this one formation covers the
entire site and all the area within a 500m radius in the Geoinsight report (p21),
the map is not reproduced here.

6. HYDROGEOLOGY
In the past when compiling a Part 1 desk study, the necessary aquifer
information, abstractions, water quality data etc. could be obtained from the
Environment Agency. In Wales this is no longer the case due to the failure of
N.R.W. (to whom the previous responsibilities of the E.A. have been devolved)
to publish them. This makes it necessary to purchase the information off a
private organisation such as Groundsure. This has been done for this report and
the full Groundsure report is attached as Appendix B. The information in the
following sections has been taken from the report. Some of this has been
referenced by page number for the benefit of anyone reviewing this report.
Aquifer designation terminology was changed by the E.A./N.R.W. in 2010 to
be consistent with the Water Framework Directive terminology and the old
major/minor aquifer terms have been replaced. Taking the superficial deposits
first, it can be seen on page 25 that the glacial material underlying the site has
been assigned a Secondary (A) Aquifer classification. Formerly known as Minor
Aquifers, these have permeable layers capable of supporting water supplies at
a local rather than strategic level. In certain cases they may support base flow in
rivers
The bedrock under the site and the entire surrounding area is also given a
Secondary (A) Aquifer rating (permeable layers). These may contain permeable
layers and are capable of supporting water supplies at a local rather than
strategic level. In certain cases they may support base flow in rivers. This reflects
the geology of the St. Maughans Formation which contains relatively thin units
of permeable sandstones interbedded with impermeable argillaceous units.
7. ABSTRACTIONS
There are several potable water wells owned by Dwr Cymru 842m-916m
northwest of the site. There is also an unspecified well at Dry Grounds farm
1230m north of the site. The wells are all too far from the site to appear on the
maps on page 34 of the report. However, they are the reason a Source
Protection Zones comes within the 500m radius of the site as is seen in Figure
12 overleaf. There are also surface water abstraction licenses for the River Usk
at 872m and 1562m distance from the site.

8. HYDROLOGY
The site lies within the Usk and Llwyd catchment areas. The major hydrological
features are the Rivers Tarrel and Usk. At its closest point the Tarrel is 420m
away where it is 13.5m wide. The Usk is over 600m away to the east, with an
average width of 36m. There is also a small unnamed stream 220m southeast of
the site.
9. FLOOD RISK
The E.A./N.R.W flood map for planning (page 48 in the Groundsure Report)
shows there is an area of Zone 2 floodplain within 250m of the site and a narrow
ribbon of Zone 3 floodplain alongside the Afon Tarrel 450m northwest of the
site. The RoFRaS map (page 49) shows an area of low risk of flooding within
250m of the site and a narrow area of high risk 450m away corresponding to the
area described above.
10. WATER QUALITY
There are three N.R.W. sampling points within 900m of the site on the River
Usk. Between 2005-2008 they were all graded A (“very good”) for chemical
quality. In the years 2005-2009 biological quality ranged from A to C.
11. POLLUTION INCIDENTS
a) There are no records of historic IPC authorisations within 500m of the site.
b) There are no records of Part A(1) and IPPC activities within 500m of the site.
c) There are no records of List 1 or 2 Dangerous Substance Inventory Sites, nor
any Red List Discharge Consents within 500m of the site.
d) There are no records of Part A(2) and Part B Activities with the exception of
West End Service Station which has a permit for unloading petrol. There have
been no Enforcements.
e) There are no Category 3 or 4 Radioactive Substance Authorisations within
500m of the site.
g) There are no Part 2A sites within 500m of the site
f) There have been no E.A./ N.R.W List 1 pollution incidents within 500m.
There have been several List 2 pollution incidents. These are listed below in
order of distance from the site:-
i)
ii)
iii)
iv)
272m southeast of the site on 13/11/2001 there was an incident with
category 2 significance. The grid reference places it on the banks of the
unnamed stream mentioned in the Hydrology section with the
pollutant being contaminated water from vegetable washings.
433m northwest of the site on the River Tarrel there have been three
incidents of the dumping of biodegradable material identified as food
and drink. These incidents were on 22/04/2014, 16/05/2014 and
10/08/2016. They were all rated as category 3 (water-minor) and
category 4 (land-no impact).
477m west of the site, on the River Tarrel at the rear of Ffrwdgrech
Industrial Estate there was a category 3 (water) and category 4 (land)
incident on 14/10/2002. The pollutant was described as general
biodegradable materials and wastes, vegetable cuttings and deposits.
The incident furthest from the site (496m west) was also on the Tarrel
at the rear of Ffrwdgrech Industrial Estate. The contaminant was
described as organic chemicals/products, and again this was rated as
category 3 (water) and category 4 (land).
To summarise, all the recorded pollution incidents within a 500m radius of the
site have been List 2 (less serious) and have all involved minor pollution incidents
on local watercourses. None could have any potential influence on the site.
12. LANDFILLS
The Groundsure report records a single landfill within 500m of the site This is
the Dinas site, 441m east of the site at its closest point. The waste license was
for Inert, Industrial, Commercial and domestic Waste. The licence ran from 1968
to 1974. The site was chosen as it was previously very low lying and prone to
flooding. The landfill has now been reinstated as playing fields and farmland. At
over 400m from the site, the migration of landfill gas would not normally be
considered a threat. The landfill has been examined by the author in the past, in
connection with another site, closer to the landfill. In order to quantify the risk
posed by the site an Environmental Search request was ordered and paid for
from Powys C.C. The main reason for purchasing the Environmental Search was
to obtain any gas monitoring data. After some incidents involving landfill gas, all
local authorities were obliged to undertake monitoring of landfills under their
jurisdiction. This included landfills that had already been closed and capped. This
indeed was the case with this landfill. The landfill had been sampled by gas
spiking in 1999. According to BS8576:2013 this is a relatively cheap, but efficient
method of producing an overview of a site’s potential for gas generation. The
results are shown below, and can be summarised as showing no methane
production with slightly elevated Carbon Dioxide readings. The CO2 readings,
whilst elevated compared to normal atmospheric levels, are comparable to
normal average readings in natural soils. It can be concluded that landfill gas can
be discounted as a possible off-site source of contamination.

13. ARCHAEOLOGICAL CONSIDERATIONS
There are no known archaeological considerations. As previously mentioned,
the current building occupies an identical footprint to Brecon Union Workhouse,
which dates from 1839. However the buildings have been much altered over the
years and now resemble other public buildings from the same period (1950’s1960) as its initial use as a hospital. The L.P.A. have indicated to the applicants
that the front, northeast facing wing of the existing building must be retained.
This is for aesthetic, rather than archaeological considerations.
14. ECOLOGICAL CONSIDERATIONS
The site is within the Brecon Beacons National Park. As this is a pre-planning
application there are currently no ecology-based conditions, but his will
probably not be the case when a full planning application is made.
15. PREVIOUS SITE STUDIES AND LOCAL AUTHORITY RECORDS
There have been no previous contamination studies of the site, either desk
based or intrusive. It is very unlikely there are any planning and building control
records held by Powys planning department that have any relevance to the site.
16. CONTAMINANTS OF CONCERN
From all the information gathered in the preceding sections it would seem that
regarding this site there are no contaminants of concern.
 The site has had several previous uses, the last being residential for
students. The reason the applicants were advised to have a Phase 1 report
produced was apparently one of its former uses as a hospital. Apart from
the disposal of clinical waste on site it is difficult to conceive of possible
sources of contamination from a hospital. Hospital incinerators are
usually readily visible from their chimney stack. Also they are usually
separate from the main hospital buildings. There is no sign of one here.
The hospital was actually a geriatric hospital, more akin to a nursing home
than a general hospital.
 There is not, and never has been, any industry, whether extractive or
manufacturing, on or near the site that could have had a possible
contaminative effect on the site.
 There have been no recorded pollution incidents on or near the site that
could have had a possible contaminative effect on the site.
 There is an area of landfill within 440m of the site. This would not normally
be considered close enough to pose a threat to the site from gas
migration. Besides the distance factor, the landfill has been tested for gas
generation twenty years ago, when it was found not to be producing
landfill gas. Therefore landfill gas can be discounted as a possible
contaminant of concern.
17. CONCEPTUAL SITE MODEL AND RECOMMENDATIONS
At this stage it is normally part of the template to produce a conceptual model
as a visual aid to understanding the three dimensional source-pathway-receptor
situation in relation to the site. This Phase 1 report has demonstrated beyond
doubt that there are no contaminants of concern. Without an on-site or off-site
source there can be no viable pathway to receptors on the site. Therefore, there
is little point in producing a pictorial conceptual model which would appear
superfluous to the report. Instead, all the facts have been presented in tabular
form overleaf. Table 1 is the tabular Conceptual Model.
This Phase 1 concludes there is no need to proceed to a Phase 2. It has been
demonstrated there are no information gaps or areas of uncertainty that require
further, intrusive investigation. Therefore there is no reason for the L.P.A. to
impose contaminated land conditions on any planning approval. In making this
recommendation it is assumed that an asbestos survey will be undertaken
before any demolition works. If required, any asbestos removal will be done by
licensed contractors. It is also assumed that the removal of the redundant fuel
tanks and associated pipework to the boiler plant will be done under a suitable
risk assessment/ method statement.

Overview of Findings
The Groundsure Geo Insight provides high quality geo-environmental information that allows geoenvironmental professionals and their clients to make informed decisions and be forewarned of potential
ground instability problems that may affect the ground investigation, foundation design and possibly
remediation options that could lead to possible additional costs.
The report is based on the BGS 1:50,000 and 1:10,000 Digital Geological Map of Great Britain, BGS
Geosure data; BRITPITS database; Non-coal mining data and Borehole Records, Coal Authority data
including brine extraction areas, PBA non-coal mining and natural cavities database, Johnson Poole and
Bloomer mining data and Groundsure's unique database including historical surface ground and
underground workings.
For further details on each dataset, please refer to each individual section in the report as listed. Where
the database has been searched a numerical result will be recorded. Where the database has not been
searched '-' will be recorded.

Guidance: The 1:10,000 scale geological interpretation is the most detailed generally available from BGS
and is the scale at which most geological surveying is carried out in the field. The database is presented as
four types of geology (artificial, mass movement, superficial and bedrock), although not all themes are
mapped or available on every map sheet. Therefore a coverage layer showing the availability of the four
themes is presented above.

3 Radon Data
3.1 Radon Affected Areas
Is the property in a Radon Affected Area as defined by the Health Protection Agency (HPA) and if so what
percentage of homes are above the Action Level? The property is in a Radon Affected Area, as between 5
and 10% of properties are above the Action Level.
The radon data in this report is supplied by the BGS/Public Health England and is the definitive map of
Radon Affected Areas in Great Britain and Northern Ireland. The dataset was created using long-term
radon measurements in over 479,000 homes across Great Britain and 23,000 homes across Northern
Ireland, combined with geological data. The dataset is considered accurate to 50m to allow for the margin
of error in geological lines, and the findings of this report supercede any answer given in the less accurate
Indicative Atlas of Radon in Great Britain, which simplifies the data to give the highest risk within any
given 1km grid square. As such, the radon atlas is considered indicative, whereas the data given in this
report is considered definitive.
3.2 Radon Protection
Is the property in an area where Radon Protection are required for new properties or extensions to
existing ones as described in publication BR211 by the Building Research Establishment?
Basic radon
protective measures are necessary.

Using this report
The following report is designed by Environmental Consultants for Environmental Professionals bringing together
the most up-to-date market leading environmental data. This report is provided under and subject to the Terms &
Conditions agreed between Groundsure and the Client. The document contains the following sections:
1. Historical Industrial Sites
Provides information on past land uses that may pose a risk to the study site in terms of potential contamination
from activities or processes. Potentially Infilled Land features are also included. This search is conducted using radii
of up to 500m.
2. Environmental Permits, Incidents and Registers
Provides information on Regulated Industrial Activities and Pollution Incidents as recorded by Regulatory Authorit ies, and sites determined as Contaminated Land. This search is conducted using radii up to 500m.
3. Landfills and Other Waste Sites
Provides information on landfills and other waste sites that may pose a risk to the study site. This search is conduc ted using radii up to 1500m.
4. Current Land Uses
Provides information on current land uses that may pose a risk to the study site in terms of potential contamination
from activities or processes. These searches are conducted using radii of up to 500m. This includes information on
potentially contaminative industrial sites, petrol stations and fuel sites as well as high pressure gas pipelines and un derground electricity transmission lines.
5. Geology
Provides information on artificial and superficial deposits and bedrock beneath the study site.
6. Hydrogeology and Hydrology
Provides information on productive strata within the bedrock and superficial geological layers, abstraction licences,
Source Protection Zones (SPZs) and river quality. These searches are conducted using radii of up to 2000m.
7. Flooding
Provides information on river and coastal flooding, flood defences, flood storage areas and groundwater flood
areas. This search is conducted using radii of up to 250m.
8. Designated Environmentally Sensitive Sites
Provides information on the Sites of Special Scientific Interest (SSSI), National Nature Reserves (NNR), Special
Areas of Conservation (SAC), Special Protection Areas (SPA), Ramsar sites, Local Nature Reserves (LNR), Areas of
Outstanding Natural Beauty (AONB), National Parks (NP), Environmentally Sensitive Areas, Nitrate Sensitive Areas,
Nitrate Vulnerable Zones and World Heritage Sites and Scheduled Ancient Woodland. These searches are conduc ted using radii of up to 2000m.
9. Natural Hazards

provide further information on issues raised within this report. Alternatively, Groundsure provide a free Technical
Helpline (08444 159000) for further information and guidance.
Note: Maps
Only certain features are placed on the maps within the report. All features represented on maps found within this
search are given an identification number. This number identifies the feature on the mapping and correlates it to
the additional information provided below. This identification number precedes all other information and takes the
following format -Id: 1, Id: 2, etc. Where numerous features on the same map are in such close proximity that the
numbers would obscure each other a letter identifier is used instead to represent the features. (e.g. Three features
which overlap may be given the identifier “A” on the map and would be identified separately as features 1A, 3A, 10A
on the data tables provided).
Where a feature is reported in the data tables to a distance greater than the map area, it is noted in the data table
as “Not Shown”.
All distances given in this report are in Metres (m). Directions are given as compass headings such as N: North, E:
East, NE: North East from the nearest point of the study site boundary.

1.6 Historical military sites
Certain military installations were not noted on historic mapping for security reasons. Whilst not all
military land is necessarily of concern, Groundsure has researched and digitised a number of Ordnance
Factories and other military industrial features (e.g. Ordnance Depots, Munitions Testing Grounds) which
may be of contaminative concern. This research was drawn from a number of different sources, and
should not be regarded as a definitive or exhaustive database of potentially contaminative military
installations. The boundaries of sites within this database have been estimated from the best evidence
available to Groundsure at the time of compilation.
Records of historical military sites within 500m of the search boundary:
0
Database searched and no data found.

Historically, Source Protection Zone maps have been focused on regulation of activities which occur at or
near the ground surface, such as prevention of point source pollution and bacterial contamination of
water supplies. Sources in confined aquifers were often considered to be protected from these surface
pressures due to the presence of a low permeability confining layer (e.g. glacial till, clay). The increased
interest in subsurface activities such as onshore oil and gas exploration, ground source heating and
cooling requires protection zones for confined sources to be marked on SPZ maps where this has not
already been done.

6.10 Ordnance Survey MasterMap Water Network
Ordnance Survey MasterMap Water Network entries within 500m of the study site
This watercourse information is provided by Ordnance Survey MasterMap Water Network. The data
provides a detailed centre line following the curve of the waterway precisely, so all distances provided in
the report should be understood as measurements to the centreline rather than a measurement to the
nearest point of the watercourse. Underground watercourses are inferred from entry and exit points so
caution is advised in using these to indicate precise locations of underground watercourses when planning
site investigation and development.

The Environment Agency/Natural Resources Wales RoFRaS database provides an indication of river and
coastal flood risk at a national level on a 50m grid with the flood rating at the centre of the grid
calculated and given above. The data considers the probability that the flood defences will overtop or
breach by considering their location, type, condition and standard of protection.
RoFRaS data for the study site indicates the property is in an area with a Very Low (less than 1 in 1000)
chance of flooding in any given year.

7.7 Groundwater Flooding Susceptibility Areas
7.7.1 British Geological Survey groundwater flooding susceptibility areas within 50m of the boundary of
the study site
Identified
Clearwater Flooding or Superficial Deposits Flooding
Superficial Deposits Flooding
Notes: Groundwater flooding may either be associated with shallow unconsolidated sedimentary aquifers
which overlie unproductive aquifers (Superficial Deposits Flooding), or with unconfined aquifers
(Clearwater Flooding).
7.7.2 Highest susceptibility to groundwater flooding in the search area based on the underlying geological
conditions
Potential at Surface
Where potential for groundwater flooding to occur at surface is indicated, this means that given the
geological conditions in the area groundwater flooding hazard should be considered in all land-use
planning decisions. It is recommended that other relevant information e.g. records of previous incidence
of groundwater flooding, rainfall, property type, and land drainage information be investigated in order to
establish relative, but not absolute, risk of groundwater flooding.
7.8 Groundwater Flooding Confidence Areas
British Geological Survey confidence rating in this result
Moderate
Notes: Groundwater flooding is defined as the emergence of groundwater at the ground surface or the
rising of groundwater into man-made ground under conditions where the normal range of groundwater
levels is exceeded.
The confidence rating is on a threefold scale - Low, Moderate and High. This provides a relative indication
of the BGS confidence in the accuracy of the susceptibility result for groundwater flooding. This is based
on the amount and precision of the information used in the assessment. In areas with a relatively lower
level of confidence the susceptibility result should be treated with more caution. In other areas with
higher levels of confidence the susceptibility result can be used with more confidence.

9.2 Radon
9.2.1 Radon Affected Areas
Is the property in a Radon Affected Area as defined by the Health Protection Agency (HPA) and if so what
percentage of homes are above the Action Level? The site is in a Radon Affected Area, as between 5 and
10% of properties are above the Action Level.
The radon data in this report is supplied by the BGS/Public Health England and is the definitive map of
Radon Affected Areas in Great Britain and Northern Ireland. The dataset was created using long-term
radon measurements in over 479,000 homes across Great Britain and 23,000 homes across Northern
Ireland, combined with geological data. The dataset is considered accurate to 50m to allow for the margin
of error in geological lines, and the findings of this report supercede any answer given in the less accurate
Indicative Atlas of Radon in Great Britain, which simplifies the data to give the highest risk within any
given 1km grid square. As such, the radon atlas is considered indicative, whereas the data given in this
report is considered definitive.
9.2.2 Radon Protection
Is the property in an area where Radon Protection are required for new properties or extensions to
existing
ones as described in publication BR211 by the Building Research Establishment?
Basic radon protective
measures are necessary.

Past underground mine workings are uncommon, localised and of limited area. The rock types present in
this area are such that minor mineral veins may be present within them on which it is possible that there
have been attempts to work these by underground methods and/or it is possible that small scale
underground extraction of other materials may have occurred. All such occurrences are likely to be
restricted in size and infrequent. It should be noted, however, that there is always the possibility of the
existence of other sub-surface excavations, such as wells, cess pits, follies, air raid shelters/bunkers and
other military structures etc. that could affect surface ground stability but which are outside the scope of
this dataset. However, if in a coalfield area you should still consider a Coal Authority mining search for the
area of interest.
