EXECUTIVE SUMMARY Site Name & Address: Oak Mill Stud, Toothill, Epping, Essex, CM5 9SF Client: Miss A. Carol Architect: Shaw & Jagger Architects Ltd Local Planning Authority: District Council Historical Site Use: Agricultural fields Present Site Use: Equestrian facilities, including stables and ménage Proposed Site Use: Single Residential Property Date of most recent investigation: Friday, 03 July 2020 - Site walkover survey Objectives: ▪ To develop a good understanding of the site’s history and environmental context; ▪ To determine the potential existence of any significant pollutant linkages which might represent a potential risk to construction workers, future occupants of the site or controlled waters; ▪ To undertake a Tier 1 ‘Contaminated Land’ investigation in accordance with CLR11 and guidance contained in the NHBC Publication 66: 2008. Geology, Hydrogeology & Hydrology: ▪ Based on the BGS online mapping, the site is likely to be underlain by a combination of superficial deposits comprising Sand and Gravel of the Stanmore Gravel Formation to the west and Lowestoft Formation – Diamicton to the east. The bedrock deposits beneath comprise Claygate Member – Clay, Silt & Sand. ▪ The BGS borehole [TL50SW78] log records Boulder Clay (Blue marl, overlaying White marl) to 9.14m bgl, underlain by Gravel, overlaying Clay to 12.2m bgl. ▪ With reference to the groundwater mapping presented on the DEFRA website, the site is located between two different superficial aquifer designations. The deposits to the west are classified as Secondary A (permeable layers supporting water supplies locally) while the deposits to the east are classified as Secondary Undifferentiated (formerly classified as minor/non-aquifer). The bedrock aquifer is designated as Secondary A. ▪ In terms of groundwater vulnerability, the site is classified as Medium-High risk on DEFRA’s Magic Map website. ▪ The site is not located within a Source Protection Zone. ▪ The site is located within Flood Zone 1. ▪ In relation to the overall hydrology, the site is mostly permeable and laid to managed grass with the only exception being the footprint of the stable block and field shelters. Historical activities on and surrounding the site may have resulted in a degree of made ground, which could affect the overall hydrology at the site. Findings: ▪ The site appears to have formed a part of an agricultural field until the early 2000s, when a single building was recorded. The building was then extended by 2010 into its current configuration. ▪ Our historic map review has identified an infilled pond located approximately 20m remote from the site.

Risk Assessment: ▪ Our desk-based research and walkover survey identified the following potential sources of contamination: i) On-site; Current/ Recent Site Use (Stables and Ménage, including limited fuel storage). ii) Off-site; Infilled pond, historic windmill, licensed discharge, recent industry. ▪ We consider that the above sources represent a LOW risk to the site and future site users. ▪ We consider the potential on-site sources of contamination to represent a LOW risk to groundwater. ▪ The potential risk from ground gas migrating onto the site, and affecting the proposed development, is considered to be LOW. Recommendations: Based on the information obtained and reviewed as part of this preliminary assessment, JPC Environmental Services would advise the following:

• Based on the low risk nature of the site, we do not consider it necessary to undertake a Phase II intrusive investigation on this occasion.

• We would, however, advocate the adoption of a ‘Discovery Strategy’. If any suspicious or malodorous soils are encountered during ground works, then work will need to be stopped until samples of the soil can be tested for a typical range of environmental contaminants.

1.0 INTRODUCTION 1.01 Brief 1.01.1 JPC Environmental Services were appointed by Shaw & Jagger Architects Ltd, on behalf our mutual client Miss A. Carol, to undertake a Phase I Contaminated Land Investigation and Risk Assessment for ‘Oak Mill Stud, Toothill, Epping, Essex, CM5 9SF ’ (hereafter referred to as ‘the site’).

1.01.2 The purpose of the investigation, comprising a desktop study and walkover survey was to: ▪ Identify any significant potential sources of ground contamination either on the site or in close proximity to it, which could have a negative impact on the proposed development. ▪ To determine the potential existence of any significant pollutant linkages that might represent a potential risk to future occupants. ▪ To determine whether any further investigations would be required, to enable the potential risk to human health and controlled waters to be assessed.

1.01.3 The investigation was carried out broadly in accordance with Contaminated Land Report 11 (CLR 11) and the updated NHBC Guidance Document “R & D Publication 66: 2008 – Guidance for the Safe Development of Housing on Land Affected by Contamination”.

1.01.4 Authority to carry out this work was received on 29 June 2020 from Shaw & Jagger Architects Ltd, via email.

1.01.5 This report shall be for the private and confidential use of Miss A. Carol, for whom it was undertaken. It should not be reproduced in whole or in part, or relied upon by a third party for any use without the express written authority of JPC Environmental Services.

1.01.6 In producing this report, we have exercised all the reasonable skill, care and diligence to be expected of an appropriately qualified and competent consultant, experienced in carrying out equivalent services for developments of a similar size, scope and complexity, value and purpose to the development.

1.02 Scope 1.02.1 The main elements of the investigation were as follows: ▪ The collection and review of historical and regulatory information relating to the site to gain an understanding of the site’s history, the local environment and potential ground conditions ▪ The formulation of a “Conceptual Site Model” to explore and evaluate the existence and potential impact of any plausible pollutant linkages ▪ To utilise the resulting information to undertake a ‘Tier 1’ human and environmental risk assessment ▪ If appropriate, make recommendations on the extent of any intrusive investigations which may be required to fully establish the condition of the site

1.02.2 The on-site investigations comprised the following:- ▪ A walkover survey of the site and surrounding area to identify the presence and types of commercial activities within the locality, and seek evidence of potential sources of on or off- site contamination.

2.0 DESK STUDY 2.01 Sources of Information 2.01.1 As part of the desk-based research, JPC Environmental Services consulted the following sources of information: - ▪ Enviro+Geo Insight Report – produced by Groundsure Ltd. ▪ Map Insight Report – produced by Groundsure Ltd. ▪ British Geological Survey (BGS) mapping and online referencing ▪ Environment Agency landfill mapping – online ▪ BR 211 Radon: Guidance on Protective Measures for New Dwellings, 2007 Edition ▪ Magic Map Website – magic.defra.gov.uk ▪ Council Planning Portal ▪ Google Earth (aerial photography)

2.02 Site Description (Walkover Survey) 2.02.1 The site walkover was conducted on Friday, 03 July 2020 by Hannah Purkis on behalf of JPC Environmental Services.

2.02.2 The site is accessed off Mill Lane, through a set of electric gates to the north of the highway. The access continues in the form of a gravelled private driveway turning 90’ west onto an open parking area also laid to gravel. The site is secure, tidy and well-presented.

2.02.3 The main building lies to the north of this area and comprises a large single storey ‘U-shaped’ barn split into loose boxes, a tack room and several storage areas which are used for equestrian purposes. As you enter the barn, loose boxes lie to the left- and right-hand sides with a tack room and breakout room in front of you. The barn benefits from running hot and cold water and heating although this is electric rather than oil based. The base of the barn is a concrete slab in good condition.

2.02.4 Continuing round to the left there are further loose boxes (7 No. in total), some of which are used for storage. A limited quantity of fuel was stored in one loose box in 3 No. small metal and plastic jerry cans which were clearly labelled. An employee confirmed that no other fuel is stored on-site. The concrete slab in this loose box was in good condition and no staining was observed.

2.02.5 Exiting the barn, to the north-east, lies a second smaller barn in which hay, feedstuffs and a ‘portaloo’ is stored. This opens out to the north onto an area of gravel used for parking, and storage of a shipping container (in which a quadbike is housed) and a horse trailer.

2.02.6 To the south east of the main building lies a ménage, while to the west lies a round pen. Both are laid to sand/ recycled tyre chippings. A muck heap and fire pit (on concrete bases and surrounded by block work on three sides, which is in good condition) lie to the south-west of the main structure. The remainder of the site is laid to gravel, soft landscaping and areas of concrete hardstanding. A single butane gas canister is stored to rear of the muck heap.

2.02.7 The site continues to the north-east along a gravel track lined with post and rail fencing and 4 No. wooden field shelters on concrete bases. These are to be removed as part of the proposals. The

site is surrounded on three sides by managed grass for grazing while to the south lies Mill Lane. A small depression is located off the south-east corner of the site that seasonally becomes a pond.

2.03 Site History 2.03.1 To ascertain the existence of any potentially contaminative former land uses within the locality, JPC Environmental Services purchased a Map Insight Report compiled by Groundsure Ltd, which contains a range of historic ‘County’ maps and modern Ordnance Survey map extracts. The extracts reviewed as part of this desk study were produced in five scales, 1:500, 1:1,250, 1:2,500, 1:10,000 (metric scale) and 1:10,560 (imperial scale), and cover the period from 1873 - 2020 with an aerial photograph provided within the Groundsure Insight Report.

2.03.2 Details of the historic land uses are summarised in the table below, while copies of the full-sized map extracts are presented within appendices for reference purposes.

2.04 Geology, Hydrogeology & Hydrology 2.04.1 To determine the nature of the underlying geology, we have consulted the 1:50,000 scale geological maps compiled by British Geological Survey (BGS). Based on these maps, the site is likely to be underlain by a combination of superficial deposits comprising Sand and Gravel of the Stanmore Gravel Formation to the west and Lowestoft Formation – Diamicton to the east. The bedrock deposits beneath comprise Claygate Member – Clay, Silt & Sand.

Geology 2.04.2 In addition to the geological mapping, we have reviewed the BGS database for nearby boreholes. The nearest borehole with a log of the underlying soils [TL50SW78] is located approximately 250m to the south-east. The log is reproduced in Table 2 below:

Table 2 - BGS Borehole Log Nature of Strata Thickness Depth (m) (m bgl) Boulder Clay (Blue marl, overlaying White marl) 9.14 9.14 Gravel, overlaying London Clay 3.05 12.2

Hydrogeology 2.04.3 With reference to the groundwater mapping presented on the DEFRA website, the is located between two different superficial aquifer designations. The deposits to the west are classified as Secondary A (permeable layers supporting water supplies locally) while the deposits to the east are classified as Secondary Undifferentiated (formerly classified as minor/non-aquifer). The bedrock aquifer is designated as Secondary A.

2.04.4 The Environment Agency divides significant groundwater catchments into three Source Protection Zones (SPZ’s) based on the potential risk associated with the migration of possible contaminants. In this instance, the site is not located within a Source Protection Zone.

2.04.5 In terms of groundwater vulnerability, the site is classified as Medium-High on the Environment Agency’s groundwater vulnerability mapping.

2.04.6 In respect of the local hydrology, there are no recorded watercourse onsite or within 250m from the site. The OS mapping and aerial photographs indicate that there are a number of isolated surface water features (ponds) within 100m of the site. The site is located within WFD catchment Cripsey Brook.

2.04.7 According to the Environment Agency’s online indicative flood mapping the site is situated within Flood Zone 1. Surface water and groundwater flooding are both stated to have a negligible risk to the site. Thus, we do not consider floodwaters as posing a significant potential pathway for soluble or surface contaminants.

2.04.8 In relation to the overall hydrology, the site is mostly permeable and laid to managed grass with the only exception being the footprint of the stable block and field shelters. Historical activities on and surrounding the site may have resulted in a degree of made ground, which could affect the overall hydrology at the site.

2.05 Statutory Searches 2.05.1 To obtain a more detailed understanding of the site, in context of the surrounding environment, JPC Environmental Services purchased a Groundsure Insight report. This report contains information derived from a database containing public record information from the Environment Agency, local authorities and other regulatory bodies.

2.05.2 The complete Groundsure Insight report is provided within the appendices.

2.05.3 Potential issues noted within the report have been sub-divided into sources, pathways and receptors and are summarised in the tables below:

2.06 Radon 2.06.1 According to the Enviro Insight report and BR211 (2007), the site is located in a lower probability Radon affected area. Therefore, as fewer than 1% of homes are above the action level for Radon, no radon protection measures are necessary in the construction of new buildings or residential dwellings.

2.07 Mineral Workings and Potentially Infilled Land 2.07.1 Our historic map review has highlighted various potentially infilled ponds within 250m of the site boundary. See Figure 2 below.

2.07.2 The pond marked A is shown on all historic maps until 1993 but is not shown after 2003. During our site walkover survey, the area was confirmed to still exist as a small depression and is, therefore, not considered to have been infilled.

2.07.3 The ponds marked B are shown on all historic maps and are, therefore not considered to have been infilled.

2.07.4 The ponds marked C are shown on historic maps until 1960 but are not shown after 1972. As such, these areas are considered to have been infilled. The risk from ground gas is greatest within Phase I Contaminated Land Assessment Report – Produced by J P Chick & Partners Ltd For: Miss A. Carol Our Reference: CE20/001 Date: 20/07/2020 Page 13

the first 20 years since infilling, however, and diminishes with time after that. As the ponds appear to have been infilled for significantly longer than this (over 45 years), they are not considered to pose a significant risk of ground gas to the proposed development.

2.07.5 In addition to the Enviro Insight report, we have consulted the Environment Agency landfill mapping. There are no historic landfills reported to be within 500m of the site.

2.08 Local Authority Information 2.08.1 During our investigation of Oak Mill Stud, Toothill, Epping, an additional request by JPC Environmental Services was made to the Environmental Information Regulations Team at Epping Forest Council. The response was received on Thursday, 09 July 2020, and is detailed below.

2.08.2 ‘According to the Council electronic systems, there has been one reported pollution incident within 250 meters of the site consisting of an incident of poorly treated septic tank effluent being discharged 230 metres east of the site.

2.08.3 Details of the areas that are potentially contaminated are detailed below: • The site has potentially contaminated land due to use as a smallholding with suspected made ground and a filled pond. • 165 metres east of the site due to use as a farm. • 175 metres south of the site due to a landfill (EPO/266/61).

2.08.4 There are a number of filled ponds within 250m of the site where the infill material is unknown:- • 20 metres south east of the site. • 100 metres south east of the site. • 105 metres south east of the site. • 165 metres south east of the site. • 168 metres north east of the site. • 175 metres south east of the site due to a filled watercourse. • 175 metres south east of the site due to a filled watercourse. • 180 metres south east of the site due to a filled watercourse. • 2 ponds 185 metres east of the site. • 245 metres south of the site. • 250 metres south east of the site.’

2.08.5 The ponds listed above refer to the same ponds listed in section 2.07 and are not considered to be infilled, or are considered to pose a low risk to the site.

2.08.6 The landfill is not shown on any of the historic maps and the local authority do not hold any additional information on it. The approximate location of the landfill is 3m lower than the site. Due to this, and the landfill’s proximity to the site, it is considered to pose a risk of ground gas to the site.

2.08.7 A full copy of the local authority response is included within the appendices.

2.09 Planning Portal 2.09.1 A search was made on Epping Forest District Council’s planning portal. This was done to further explore the evolution of the site and any available information related to nearby sites. While

there are numerous applications within 250m of the site boundary, the majority do not provide any new or significant information related to contaminated land.

2.09.2 Application [EPF/0532/17] et. al refer to the construction of a residential bungalow on land 100m to the south-east of the site. The attached Phase I report confirms that the pond in this area has been infilled and includes recommendation for an ‘Intrusive investigation to establish ground conditions and confirm the presence or absence of soil or groundwater contamination’.

3.0 CONCEPTUAL SITE MODEL 3.01 Introduction 3.01.1 The “conceptual site model” is a simplified representation of the ground conditions that exist on site, which is subsequently used to assess the potential risk to human and environmental receptors. According to the contaminated land report (CLR11) “a conceptual model represents the characteristics of the site in diagrammatic or written form; that shows the possible relationships between contaminants, pathways and receptors”.

3.01.2 Although the model is formulated during the initial phase of the investigation it is subject to change, as new information comes to light, and our understanding of the site improves. It is central to the risk assessment process and therefore must consider all potential relationships/interactions. The four key aspects to the model are listed below:

Source(s) These can include current or historic activities taking place either on or near the site, which may have had a negative impact on surface or sub-surface soils, or groundwater.

Pathway(s) This is the route by which contaminants migrate between a source and an available receptor.

Receptor(s) These are varied and can include human or non-human organisms and eco-systems; controlled waters such as groundwater or surface water bodies; and structures.

Linkage(s) These exist where all three of the previous elements are present, indicating a link between an identified source and a potential receptor via a pathway.

Infilled Land Landfill Ground Gas, Unknown Fill 175 Material

3.03 Potential Contaminant Pathways Table 7 - Identified Potential Pathways Pathway Inhalation - Potential inhalation of contaminants in dust/ fibrous form. Ingestion - Future site users could swallow small quantities of soil derived dust originating from soft landscaped/ garden areas or disturbed ground. Dermal absorption - Contaminants present within surface or sub-surface soils/ fill material can enter the human body through the skin or via open wounds. Buried services - If elevated levels of petroleum hydrocarbons are present within surface/ subsurface soils, then ‘plastic’ drinking water pipe can become compromised. Migration/ Leaching - Potential for migration of contaminants through soil/ groundwater. Migration of gas – Modern construction techniques can cause accumulation of gas within structures, this can expose site users to gas and lead to explosion (where methane is present).

3.04 Potential Contaminant Receptors Table 8 - Identified Potential Receptors Receptor Future site users - Future site users could be affected by contaminants in the soil, entering the mains water system or ground gas entering the building. Construction workers - Workers involved with future site clearance and preparatory work will be exposed to contaminants present within on-site soil, should they exist. Buildings and Infrastructure - Modern construction techniques can cause accumulations of gas, if gas is able to accumulate within new, or converted, buildings there is potential for an explosion. Buried services - Plastic drinking water pipes are vulnerable to petroleum hydrocarbons. On-site soil - Particularly close to the surface, may have been impacted by historic activities.

3.05 Plausible Pollutant Linkages 3.05.1 Using the ‘source – pathway – receptor’ tables above, potential pollutant linkages are identified. An assessment of the likely significance of each linkage is then considered, which would include; the possible extent and mobility of the source; the sensitivity of the receptor and the type of migration/ exposure pathways.

3.05.2 An assessment of the probability and the magnitude of potential risk is presented below to give a valuation of each potential pollutant linkage identified and their significance.

3.05.3 This assessment is undertaken based on the current proposal for the site at the time of issuing this report, which is for the conversion of the existing structure into a single residential dwelling.

3.05.4 This qualitative risk assessment has been undertaken in accordance with CIRIA C552: Contaminated Land Risk Assessment, A Guide to Good Practice (Rudland et al., 2001).

3.05.5 The level of potential risk ascribed to each linkage is based on the following criteria: Table 10 - Risk Classification Risk Description Classification Very high risk There is a high probability that severe harm could arise to a designated receptor from an identified hazard at the site without appropriate remedial action. High risk Harm is likely to arise to a designated receptor from an identified hazard at the site without appropriate remedial action. Moderate risk It is possible that without appropriate remedial action harm could arise to a designated receptor but it is relatively unlikely that any such harm would be severe, and if any harm were to occur it is more likely that such harm would be relatively mild. Low risk It is possible that harm could arise to a designated receptor from an identified hazard but is likely that, at worst, this harm if realised would normally be mild. Negligible risk The presence of an identified hazard does not give rise to the potential to cause significant harm to a designated receptor.

4.0 ENVIRONMENTAL ASSESSMENT 4.01 Summary of Key Drivers 4.01.1 The site appears to have formed a part of an agricultural field until the early 2000s, when a single building was recorded. The building was then extended by 2010 into its current configuration. The main driver for environmental risk on this site is the nearby infilled pond. The other identified potential sources, such as the current/ recent site use, historic windmill, licensed discharges, and off-site industry, are less likely to have had any direct adverse impacts on the site, the proposed development or future site users.

4.02 Environmental Risk Assessment Human Health 4.02.1 The proposed development will lead to an increase in the number of people occupying the site, therefore the condition of the underlying soils will determine the risk posed to future occupants. Due to the nature of the development, the possible production and consumption of home-grown produce presents a pathway for potential contaminants. The risk posed to future occupants from the identified potential sources is considered to be LOW.

Controlled Waters 4.02.2 The site is not located within a Groundwater Source Protection and is underlain by relatively permeable geology. Due to the nature of the potential on-site sources, the risk to groundwater is considered to be LOW.

Buildings 4.02.5 Where present, infilled land represents a potential source of ground gas to any newly built or refurbished structures. Our desk-based research has identified some infilled ponds and a historic landfill site. The potential risk of ground gas migrating to/ accumulating beneath the converted building is, therefore considered to be LOW/ MODERATE.

4.03 Environmental Litigation (Part IIA) 4.03.1 Part IIA only applies to land with chemical contamination, where the contaminants pose an unacceptable risk to human health or the wider environment i.e. land where significant pollutant linkages have been identified. The legislation also only considers risks associated with current site use, leaving any risks associated with a future use to be addressed by the planning system.

4.03.2 Based on our understanding of the previous site uses, and the apparent condition of the site established by our visual survey, we consider it extremely unlikely that the site would be classified as a Contaminated Land under Part IIA of the Environmental Protection Act.

4.04 Further Investigations 4.04.1 Based on the low risk nature of the site, we do not consider it necessary to undertake a Phase II intrusive investigation on this occasion. We would, however, recommend the installation of at least three gas monitoring wells and that gas readings are collected/recorded at fortnightly intervals for a period of three months (i.e. six visits).

5.0 RECOMMENDATIONS 5.01 Based on the information obtained and reviewed as part of this preliminary assessment, JPC Environmental Services would advise the following:

• Based on the low risk nature of the site, we do not consider it necessary to undertake a Phase II intrusive investigation on this occasion.

• We would, however, advocate the adoption of a ‘Discovery Strategy’. If any suspicious or malodorous soils are encountered during ground works, then work will need to be stopped until samples of the soil can be tested for a typical range of environmental contaminants.

• We recommend the installation of at least three gas monitoring wells and that gas readings are collected/recorded at fortnightly intervals for a period of three months (i.e. six visits). Alternatively, the local authority may accept the inclusion of gas protection measures

5.3 Groundwater vulnerability

Records within 50m 3

An assessment of the vulnerability of groundwater to a pollutant discharged at ground level based on the hydrological, geological, hydrogeological and soil properties within a one kilometre square grid. Groundwater vulnerability is described as High, Medium or Low as follows: High - Areas able to easily transmit pollution to groundwater. They are likely to be characterised by high leaching soils and the absence of low permeability superficial deposits. Medium - Intermediate between high and low vulnerability. Low - Areas that provide the greatest protection from pollution. They are likely to be characterised by low leaching soils and/or the presence of superficial deposits characterised by a low permeability.

Ambiental Risk Analytics surface water (pluvial) FloodMap identifies areas likely to flood as a result of extreme rainfall events, i.e. land naturally vulnerable to surface water ponding or flooding. This data set was produced by simulating 1 in 30 year, 1 in 100 year, 1 in 250 year and 1 in 1,000 year rainfall events. Modern urban drainage systems are typically built to cope with rainfall events between 1 in 20 and 1 in 30 years, though some older ones may flood in a 1 in 5 year rainfall event. Features are displayed on the Surface water flooding map on page 48 The data shown on the map and in the table above shows the highest likelihood of flood events happening at the site. Lower likelihood events may have greater flood depths and hence a greater potential impact on a site.

9.1 Groundwater flooding

Highest risk on site Low

Highest risk within 50m Low

Groundwater flooding is caused by unusually high groundwater levels. It occurs when the water table rises above the ground surface or within underground structures such as basements or cellars. Groundwater flooding tends to exhibit a longer duration than surface water flooding, possibly lasting for weeks or months, and as a result it can cause significant damage to property. This risk assessment is based on a 1 in 100 year return period and a 5m Digital Terrain Model (DTM). Features are displayed on the Groundwater flooding map on page 50 This data is sourced from Ambiental Risk Analytics.

11.5 Conservation Areas

Records within 250m 0

Local planning authorities are obliged to designate as conservation areas any parts of their own area that are of special architectural or historic interest, the character and appearance of which it is desirable to preserve or enhance. Designation of a conservation area gives broader protection than the listing of individual buildings. All the features within the area, listed or otherwise, are recognised as part of its character. Conservation area designation is the means of recognising the importance of all factors and of ensuring that planning decisions address the quality of the landscape in its broadest sense. This data is sourced from English Heritage, Cadw and Historic Environment Scotland.

13.4 Limestone Pavement Orders

Records within 250m 0

Limestone pavements are outcrops of limestone where the surface has been worn away by natural means over millennia. These rocks have the appearance of paving blocks, hence their name. Not only do they have geological interest, they also provide valuable habitats for wildlife. These habitats are threatened due to their removal for use in gardens and water features. Many limestone pavements have been designated as SSSIs which affords them some protection. In addition, Section 34 of the Wildlife and Countryside Act 1981 gave them additional protection via the creation of Limestone Pavement Orders, which made it a criminal offence to remove any part of the outcrop. The associated Limestone Pavement Priority Habitat is part of the UK Biodiversity Action Plan priority habitat in England. This data is sourced from Natural England.

20 Soil chemistry

20.1 BGS Estimated Background Soil Chemistry

Records within 50m 6

The estimated values provide the likely background concentration of the potentially harmful elements Arsenic, Cadmium, Chromium, Lead and Nickel in topsoil. The values are estimated primarily from rural topsoil data collected at a sample density of approximately 1 per 2 km2. In areas where rural soil samples are not available, estimation is based on stream sediment data collected from small streams at a sampling density of 1 per 2.5 km2; this is the case for most of Scotland, Wales and southern England. The stream sediment data are converted to soil-equivalent concentrations prior to the estimation.

Subject: Environmental Information Regulations Request

Dear Ms Purkis

I am writing with regards to your recent request for information under Environmental Information Regulations. Please find below our reply to the enquiry you made under this scheme on 3rd July 2020.

Drainage Informative – • This response uses the site plan provided for this enquiry.

Could you advise if there are any environmental issues we should be aware of locally; pollution incidents, known areas of contamination, records of below ground tanks etc

According to the Council electronic systems, there has been one reported pollution incident within 250 meters of the site consisting of an incident of poorly treated septic tank effluent being discharged 230 metres east of the site.

There are no recorded private water supplies monitored under the Private Water Supply Regulations 2016 (England) located within 1000 metres of this site. For any private water supplies used for other purposes eg irrigation, please consult the Environment Agency and/or the British Geological Survey.

There are no records on Council electronic systems of this site being inspected or investigated under Part IIA of the Environmental Protection Act 1990. However, our GIS database shows areas of land contamination within a 250m radius. As such the site forms part of the Council’s Contaminated Land Strategy and is therefore prioritised over other sites however is not currently planned for any future inspection or investigation.

Records of oil storage tanks are held by .

Details of the areas that are potentially contaminated are detailed below:

• The site has potentially contaminated land due to use as a smallholding with suspected made ground and a filled pond. • 165 metres east of the site due to use as a farm. • 175 metres south of the site due to a landfill (EPO/266/61)

There are a number of filled ponds within 250m of the site where the infill material is unknown:-

• 20 metres south east of the site. • 100 metres south east of the site. • 105 metres south east of the site. • 165 metres south east of the site. • 168 metres north east of the site. • 175 metres south east of the site due to a filled watercourse. • 175 metres south east of the site due to a filled watercourse. • 180 metres south east of the site due to a filled watercourse. • 2 ponds 185 metres east of the site. • 245 metres south of the site. • 250 metres south east of the site.

Public Health Nothing to report.

GIS Mapping Please find attached a printout from our GIS Contaminated Land database of the site requested. There are some potential sources of contamination to the site in the nearby area. This is due to a yard, small holdings and filled ponds in the nearby area. It is noted that this map is generated from a draft internal database and is not meant to be definitive, but instead assist you with your investigations.

If you are dissatisfied with the handling of your request, you have the right to ask for an internal review. Internal review requests should be submitted within two months of the date of receipt of the response to your original letter and should be addressed to: [email protected]

Please remember to quote the reference number above in any future communications.

If you are not content with the outcome of the internal review, you have the right to apply directly to the Information Commissioner for a decision. The Information Commissioner can be contacted at: Information Commissioner’s Office, Wycliffe House, Water Lane, Wilmslow, Cheshire SK9 5AF.
