EXECUTIVE SUMMARY AND CONCEPTUAL SITE MODEL

Purpose of This Phase 2 Intrusive Works Factual Report Report

Client NMC Nomenca Ltd

Site Land adjacent to Stoke Lane, Stoke Bardolph, Burton Joyce, Nottingham

Site Location The site is located on Stoke Lane, which is a narrow country road located immediately to the west of the small village of Stoke Bardolph. The site is located approximately 4km to the east of Nottingham City Centre, within the district of Gelding. The approximate postcode for the site is NG14 5HQ.

Current Use & The site forms a grass area adjacent to the existing Stoke Bardolph Sewage Treatment Description Works (STW) septic tank site. The site is owned and operated by Severn Trent Water. It is situated in a rural area with suburban development to the west. It is sited adjacent to arable land and the River Trent, which lies approximately 500m east. SITEINFORMATIONSETTING & Development The intrusive works are associated with proposed upgrades to the Severn Trent network on the land adjacent to Stoke Lane.

Geology The site is underlain by Superficial Deposits.

Overview of The intrusive works comprised one borehole (4.5m below ground level) to obtain Grange Geo information on the ground conditions at the site. A groundwater monitoring piezometer Intrusive Works was installed in this borehole to monitor the depth of the water table. The collection of samples for chemical analysis (soil and water) and in-situ testing was also carried out.

Findings of the Made Ground Intrusive Works Reddish brown to dark brown, slightly sandy, slightly gravelly Clay. The gravels were fine to medium sub-angular to rounded quartzite with rare brick. Abundant roots noted in the lower layer of the Made Ground between 0.4m bgl and 0.8m bgl.

Alluvium Highly variable, forming four distinct layers. Reddish brown, slightly sandy, slightly gravelly Clay with gravels of fine to medium, sub-rounded quartzite was observed to 1.3m bgl. A thin layer of firm, grey, silty Clay was present from 1.5m bgl. A layer of Peat, 0.3m thick, was then present to 1.8m bgl, followed by soft to firm, grey Clay with decayed rootlets to 2m bgl.

INTRUSIVEWORKS Holme Pierrepont Sand and Gravel Member Medium dense, orange to brown gravelly Sand. Gravels of fine to coarse, sub-rounded quartzite.

Evidence of contamination No visual or olfactory evidence of contamination was encountered.

Groundwater A groundwater strike was recorded at 3m bgl, with the water level rising to 2.2m bgl after 20 minutes. A groundwater monitoring piezometer was installed at 3.3m bgl.

Contamination One soil sample was taken from the Made Ground. The testing results have been Testing screened against Grange GeoConsulting Limited GAC screening values (provided in Appendix E) to carry out an assessment of potential risks associated with contamination. The sample did not record any contaminants exceeding the relevant GACs and did not contain asbestos. One groundwater sample was taken following the drilling of the borehole at approximately 2.5m bgl. The risks to groundwater and surface water from contaminants on site have been assessed against the Environment Agency (2006) Remedial Targets CONCLUSIONS ASSESSMENT & ASSESSMENT& Methodology (RTM). Acceptable Water Quality Targets are defined for protection of human health (based on UK Drinking Water Standards) and for the protection of aquatic ecosystems (Environmental Quality Standards).

Grange GeoConsulting iv NMC Nomenca Ltd Phase 2 Intrusive Works at Land adjacent to Stoke Lane, Stoke Bardolph, Burton Joyce, Nottingham R17026

The sample of groundwater taken from WS1 during the ground investigation was not found to contain any contaminant concentrations exceeding the Environmental Quality Stands. Three exceedances of the UK drinking water standards were recorded.

Conclusions The ground conditions across the site, as proven during the intrusive works, are in general accordance with the published geological literature. Limited thicknesses of Made Ground overlie Superficial Deposits of Alluvium (which contained a thin layer of peat) and the Holme Pierrepont Sand and Gravel Member. The soil sample taken did not record concentrations of contaminants exceeding the relevant GACs and did not contain asbestos. The water sample did not record any contaminant concentrations exceeding the Environmental Quality Stands, although three exceedances of the UK drinking water standards were recorded. Although the highly-elevated concentration of manganese recorded in the groundwater at the site is not considered to be a risk to the proposed Severn Trent upgrade works, it is recommended that consideration is given to the investigation of elevated manganese concentrations in the vicinity of the STW, by Severn Trent Water. There is not considered to be a risk from contamination at the site. It is recommended that appropriate Health & Safety precautions, dust control and PPE are adopted during any future earthworks on site. Good practice should always be adopted.

1.0 INTRODUCTION

1.1 Terms of Reference

Grange GeoConsulting Limited was commissioned by NMC Nomenca Ltd to undertake intrusive works, associated with proposed upgrades to the Severn Trent network, on the land adjacent to Stoke Lane.

One borehole (WS1) was advanced to obtain information on the ground conditions to support proposed Severn Trent network upgrade works. The borehole was located within a grass area, adjacent to the existing Stoke Bardolph Sewage Treatment Works (STW) septic tank site. The site is owned and operated by Severn Trent Water. The STW serves most of the Nottingham catchment (roughly 650,000 inhabitants) and treats trade waste from a local livestock rendering plant.

This report summarises the findings of the intrusive works carried out in March 2017 by Grange GeoConsulting Limited and the laboratory testing undertaken.

Authorisation to proceed with this Factual Report was given by NMC Nomenca Ltd via email.

The site is located on Stoke Lane, which is a narrow country road, located immediately to the west of the small village of Stoke Bardolph. Residential properties with gardens are present to the south-west, but do not overlook the site. The site is located approximately 4km to the east of Nottingham City Centre, within the district of Gelding. The site is situated in a rural area with suburban development to the west. It is sited adjacent to arable land and the River Trent, which lies approximately 500m to the east. The approximate postcode for the site is NG14 5HQ. A Site Location Plan (Drawing R17026_DWG1) is presented in Appendix A.

1.2 Objectives

The objective of the intrusive works was to characterize the underlying ground conditions and assess the environmental quality of the soils and their potential to adversely impact on human health and the wider environment. This included an assessment of the level of contamination at the site.

1.3 Scope of Works

The scope of works, as outlined in the Grange Geoconsulting Limited proposal, dated 19th March 2017, is summarised below:

• One dynamic window sampling borehole to allow the collection of soil samples for chemical analysis and to allow in-situ testing to be undertaken;

• Installation of a groundwater monitoring piezometer in this borehole to monitor the depth of the water table;

• Chemical (contamination analysis) testing of soils and groundwater; and

• Collaboration of the findings within a Factual Report.

4.0 CONTAMINATION RISK ASSESSMENT AND LABORATORY TESTING RESULTS

A risk-based approach is used for the assessment of contamination. This requires identification of a contaminant source, a receptor, and a realistic pathway via which the contaminant may reach the receptor. The key receptors considered in this assessment are human health (site users and groundworkers) and groundwater (Alluvium and Holme Pierrepont Sand and Gravel Member).

The Risk Assessment is a two-stage process. The first stage is to perform a Generic Quantitative Risk Assessment (GQRA) - the soil test results have been compared against the relevant Generic Assessment Criteria (GAC). In the absence of a complete regulatory set of screening values, derived using the CLEA Framework, Grange GeoConsulting Limited GAC screening values have been utilised and are based on the following:

• Category 4 Screening Levels (C4SLs) published by DEFRA;

• The 2014 Land Quality Management (LQM) / Chartered Institute of Environmental Health (CIEH) Suitable for Use Levels for Human Health Risk Assessment (S4ULs); and

• Guidance values produced by the Environmental Industries Commission (EIC), the Association of Geotechnical and Geoenvironmental Specialists (AGS), and Contaminated Land: Application in Real Environments (CL:AIRE) in December 2009.

The second stage of the Risk Assessment process is risk evaluation, which comprises an authoritative review of the findings with other pertinent information in cases where the GACs are exceeded, to consider if exceedances may be acceptable in the context of the site.

4.1 Human Health

This is a Tier 2 assessment, using GAC soil screening values, and involves generic human health risk assessment for the CLEA scenario: Residential with plant uptake. It should be noted that this is a conservative risk assessment, given the nature and use of the site.

GACs based on a Soil Organic Matter Content (SOM) of 1% have been used, this is a conservative approach (SOM for Made Ground on site was 2.5%).

One sample was taken and screened from the Made Ground (WS1 at 0.6m bgl). The chemical testing results have been screened against Grange GeoConsulting Limited GAC screening values (provided in Appendix E) to carry out an assessment of potential risks associated with contamination. Justification for the criteria adopted for this Risk Assessment is given in Appendix D. In cases where the sample tested for a given substance was below the GACs, no further consideration is necessary for that substance.

4.1.1 Controlled Waters

One groundwater sample was taken following the drilling of the borehole at approximately 2.5m bgl. The risks to groundwater and surface water from contaminants on site have been assessed against the Environment Agency (2006) Remedial Targets Methodology (RTM). Pollutants from contaminated land sites are considered as passive inputs under the European

Grange GeoConsulting 12 NMC Nomenca Ltd Phase 2 Intrusive Works at Land adjacent to Stoke Lane, Stoke Bardolph, Burton Joyce, Nottingham R17026

Water Framework Directive (2000/60/EC), and as such are regulated under the Agency’s ‘limit’ pollution objective.

Acceptable Water Quality Targets (WQT) are defined for protection of human health (based on UK Drinking Water Standards (DWS)) and for the protection of aquatic ecosystems (Environmental Quality Standards (EQS)). World Health Organisation drinking water standards can also be used for the protection of human health.

4.2 Risk Evaluation

4.2.1 Human Health

The sample did not record concentrations of any contaminants that exceeded the relevant GACs, with the concentrations of many contaminants below detection limits. The sample was not found to contain asbestos.

4.2.2 Controlled Waters

The sample of groundwater taken from WS1 was not found to contain any contaminant concentrations exceeding the Environmental Quality Stands.

Three exceedances of the UK drinking water standards were recorded and are summarised in Table 4.1. It should be noted that the use of drinking water standards to undertake a risk assessment for the site is a very conservative approach, particularly as the water within the borehole will not be used as a potable water supply.

Table 4.1: Groundwater exceedances of UK drinking water standards

Contaminant Concentration recorded in groundwater sample UK drinking water standard

Sulphate as SO4 460 mg / litre 250 mg / litre

Nitrate as NO2 2.87 mg / litre 0.5 mg / litre

Manganese 4.6 mg / litre 0.05 mg / litre

The concentration of sulphate (as SO4) of 460 mg / litre at the site, although in exceedance of the UK drinking water standard, is not considered to pose a risk to the site due to the conservative nature of this criteria.

The concentration of nitrate (as NO2) of 2.87 mg / litre, recorded at the site exceeds the UK drinking water standard, though it is below the World Health Organisation drinking water standard (for short-term exposure), of 3 mg / litre. The concentration of nitrate as NO2 in groundwater is therefore not considered to pose a risk to the site.

The concentration of manganese recorded at the site is extremely high (4.6 mg / litre). It is some ninety-two times the UK drinking water standard. This is likely to be due to the presence of a Sewage Treatment Works (STW) near the site, which is a common cause of elevated manganese concentrations in groundwater. The World Health Organisation drinking water (absolute) maximum recommended concentration is 4 mg / litre. It is noted that the concentration of manganese above 4 mg / litre may significantly affect the appearance, taste

Grange GeoConsulting 13 NMC Nomenca Ltd Phase 2 Intrusive Works at Land adjacent to Stoke Lane, Stoke Bardolph, Burton Joyce, Nottingham R17026

or odour of the water. The concentration at the site exceeds the World Health Organisation drinking water standard. Although this concentration is not considered to be a risk to the proposed Severn Trent upgrade works, it is recommended that consideration is given to the investigation of elevated manganese concentrations in the vicinity of the STW, by Severn Trent Water.

5.0 CONCLUSIONS AND RECOMMENDATIONS

5.1 Ground Conditions

The ground conditions across the site, as proven during the intrusive works, are in general accordance with the published geological literature. Limited thicknesses of Made Ground overlie Superficial Deposits of Alluvium (which contained a thin layer of Peat) and the Holme Pierrepont Sand and Gravel Member.

5.2 Groundwater

A groundwater strike was recorded at 3m bgl during drilling in WS1, with the water level rising to 2.2m bgl after 20 minutes. A groundwater monitoring piezometer was installed to 3.3m bgl.

5.3 Contamination Testing

The soil sample taken did not record concentrations of contaminants exceeding the relevant GACs and did not contain asbestos.

The sample of groundwater taken from WS1 was not found to contain any contaminant concentrations exceeding the Environmental Quality Stands although three exceedances of the UK drinking water standards were recorded.

Although the highly-elevated concentration of manganese recorded in the groundwater at the site is not considered to be a risk to the proposed Severn Trent upgrade works, it is recommended that consideration is given to the investigation of elevated manganese concentrations in the vicinity of the STW by Severn Trent Water.

There is not considered to be a risk from contamination at the site.

It is recommended that appropriate Health & Safety precautions, dust control and PPE are adopted during any future earthworks on site.

RISK ASSESSMENT RATIONALE

The work presented in this report has been carried out in general accordance with recognised best practice as detailed in guidance documents such as in BS5930:1999 and BS10175:2001. Important aspects of the risk assessment process are transparency and justification. The rationale behind the risk assessments presented is given in this appendix.

A preliminary risk assessment is made of both geotechnical and geo-environmental hazards identified at the desk study stage and confirmed (or amended) at the ground investigation stage. This is based on a simple matrix of probability of occurrence versus the consequence, as explained below. In the case of geo-environmental hazards, the risk assessment process proceeds to the next level, the generic risk assessment, in which actual contaminant concentrations are considered.

Preliminary Risk Assessment (Geotechnical Risk Register)

The preliminary geotechnical risk register is compiled in accordance with the Highways Agency Design Manual for Roads and Bridges HD/02. This requires an estimation of the probability of an event happening multiplied by the impact or consequences of that event. Five levels of probability and impact are given scores and these are multiplied to give a risk rating and a qualitative risk level is assigned as in Table A, based on the terminology of Clayton (2001).

Table A: Geotechnical Risk Rating Assessment of Geotechnical Risks (Risk Register)

Probability (P) Impact (I) Impact in terms Risk Rating (R = Risk Level of cost or time (% P x I) of construction cost or time) Very likely (5) Very High (5) >25% 17 to 25 Intolerable Likely (4) High (4) 10 to 25% 13 to 16 Intolerable Probable (3) Medium (3) 4 to 10% 9 to 12 Substantial Unlikely (2) Low (2) 1 to 4% 5 to 8 Tolerable Negligible (1) Very Low (1) <1% 1 to 4 Trivial

Preliminary Risk Assessment (Geoenvironmental Consequences and Probability)

The Preliminary Risk Assessment includes a geo-environmental Hazard Identification, which seeks to list all the suspected contaminant sources, the receptors that might be harmed by those sources and the pathways via which the sources might reach the receptors to cause the harm. The source-pathway-receptor concept is known as a pollution linkage, and only when a linkage is complete is there any possibility of risk of harm arising.

The Hazard Identification evaluates all the possible pollution linkages in tabular form. Professional judgement is then used to evaluate which of these pollution linkages may be considered as plausible. Plausible pollution linkages are unacceptable risks in terms of the current contaminated land regime legal framework and require either remediation or further assessment. These are normally addressed via intrusive ground investigation and the chemical analysis of soil and water samples.

Where no plausible linkage identified, the linkage is classed as ‘no linkage’ in the summary table and no further action is required. If a linkage is plausible, a comparison is made of consequence against probability in general accordance with the guidance given in CIRIA Report C552 (Rudland et al 2001). Classification of consequences and probability are given in CIRIA C552 Tables 6.3 and 6.4, respectively, but there are several inconsistencies in the original Table 6.3, in particular relating to ‘significant harm or significant possibility of significant harm’ (SH/SPOSH). Consequently, the table has been updated by Grange Geo in line with current practice and is given in Table B below. Also added are scores from 1 to 4 for each category.

NMC Nomenca Ltd Phase 2 Intrusive Works at Land adjacent to Stoke Lane, Stoke Bardolph, Burton Joyce, Nottingham R17026

The basis of the classification is that ‘severe’ and ‘major’ are likely to result in SH/SPOSH as defined by the EPA 1990, Part 2A, with ‘severe’ resulting in acute harm. ‘Moderate’ lies below the level of SH/SPOSH but above the level of ‘no harm’ as implied by the relevant Generic assessment criterion (GAC, see below). Minor lies below the ‘no harm’ level.

Table B: Classification of Consequences of Geoenvironmental Risks Classification of Consequences for Geoenvironmental Risks Classification Definition Examples Severe Concentration of contaminants is Human health: short-term (acute) effects likely to result in (4 points) likely to (or is known from significant harm. E.g. high conc. of cyanide at the surface previous data to) exceed that of an informal recreational area. indicative of unacceptable intake or contact. Planting: complete and rapid die-back of landscaped areas. I.e. >>SH/SPOSH, concentrations are high enough to cause acute Controlled waters: short-term pollution, e.g. major spillage (short-term) effects. into controlled water.

Buildings etc.: catastrophic damage, e.g. explosion causing collapse.

Ecosystems: short-term risk to an ecosystem or organism forming part of that ecosystem in a designated protected area, e.g. by contamination spillage.

Site workers: risk assessment required to determine PPE and this may involve USEPA Level A, B or C protection. Major Concentration of contaminants is Human health: long-term (chronic) effects likely to result (3 points) likely to (or is known from in significant harm. E.g. high conc. of contaminants close previous data to) exceed that to the surface of a development site. indicative of unacceptable intake or contact. Planting: stressed or dead plants in landscaped areas.

I.e. >SH/SPOSH. Controlled waters: pollution of sensitive water resources, e.g. leaching into major or minor aquifers or rivers.

Buildings etc.: damage renders unsafe to occupy.

Ecosystems: death of species in an ecosystem in a designated protected area, e.g. by contamination spillage.

Site workers: risk assessment required to determine PPE and this may involve USEPA Level B, C or D protection. Moderate Concentration of contaminants is Human health: harm but probably not significant harm (2 points) likely to (or is known from unless particularly sensitive individual within the receptor previous data to) exceed that group. May be aesthetic/olfactory impacts. indicative of no harm but not unacceptable intake or contact. Planting: damage to plants in landscaped areas, e.g. stunted growth, discoloration. I.e. >SVG/GAC but

Buildings etc.: damage to sensitive buildings etc.

Ecosystems: minor change in an ecosystem in a designated protected area, but not significant harm.

Site workers: risk assessment required to determine PPE and this may involve USEPA Level C or D protection.

Classification of Consequences for Geoenvironmental Risks Classification Definition Examples Minor Concentration of contaminants is No measurable effects, but simple PPE required (USEPA (1 point) likely to (or is known from Level D protection, i.e. overalls, boots, goggles, hard hat). previous data to) be less than that indicative of no harm.

I.e.

CIRIA Table 6.4 is reproduced as Table C below, but also with the addition of scores from 1 to 4. This provides an estimate of the probability that the event described by the pollution linkage will occur. For example, the likelihood that pollution of groundwater will occur by leaching of metals into the aquifer.

Table C: Classification of Probability of Geoenvironmental Risks Classification of Probability of Geoenvironmental Risks Classification Definition High There is a pollution linkage and an event that either appears very likely in the short (4 points) term and almost inevitable over the long term, or there is evidence at the receptor of harm or pollution. Medium There is a pollution linkage and all the elements are present and in the right place, (3 points) which means that it is probable that an event will occur.

Circumstances are such that an event in not inevitable, but possible in the short term and likely over the long term. Low There is a pollution linkage and circumstances are possible under which an event (2 points) could occur.

However, it is no means certain that even over a longer period such event could take place, and is less likely in the shorter term. Unlikely There is a pollution linkage but circumstances are such that it is improbable that an (1 point) event would occur even in the very long term.

The perceived level of risk for each pathway is then derived from the probability versus consequences matrix, modified after CIRIA C552 Table 6.5, given in Table D below. The scores are summed accordingly and the result assigned a risk level by dividing the range between the minimum score of 1 and the maximum score of 16 equally into 5 categories i.e. 1 to <4 is very low risk, 4 to <7 is low risk, 7 to <10 is moderate risk, 10 to <13 is high risk and 13 to 16 is very high risk.

Table D: Qualitative Risk Level from Consequence and Probability Consequence product Severe (4) Major (3) Moderate (2) Minor (1)

16 = Very high High (4) 12 = High risk 8 = Moderate risk 4 = Low risk risk Medium 12 = High risk 9 = Moderate risk 6 = Low risk 3 = Very low risk (3) Low (2) 8 = Moderate risk 6 = Low risk 4 = Low risk 2 = Very low risk Probability Unlikely 4 = Low risk 3 = Very low risk 2 = Very low risk 1 = Very low risk (1)

This approach assumes an equivalence between probability and consequences and ignores the difficulty that can arise where to probability of occurrence appears to be almost negligible but the consequences are very severe. In such conditions, there is a degree of subjectivity in assessing the level of risk and it could be low, moderate or high. Such risks may require specialist consideration beyond the scope of this standard report.

A description of the classified risks and the likely action required can be determined from Table E.

NMC Nomenca Ltd Phase 2 Intrusive Works at Land adjacent to Stoke Lane, Stoke Bardolph, Burton Joyce, Nottingham R17026

Table E: Description of the Classified Risks and Likely Action Required Description of Classified Risks and Likely Action Required Very High Risk A significant pollution linkage, including actual evidence of significant harm or significant possibility and significant harm, is clearly identifiable at the site (e.g. from visual or documentary evidence) under current conditions, with potential for legal and/or financial consequences for the site owner or other Responsible Person. Remediation advisable based on acute impacts being likely. Immediate action should be considered. High Risk A pollution linkage is identifiable at the site under current and future use conditions. Although likely, there is no obvious actual evidence of significant harm or significant possibility and significant harm under current conditions. Extent of risk is therefore subject to confirmation by investigation and risk assessment and most likely to be deemed significant. Remediation required for redevelopment and may also be required under Part 2A for existing receptors. Moderate Risk A pollution linkage is identifiable at the site under current and future use conditions. However, it is not likely to be a significant linkage under current conditions. Actual extent of risk subject to confirmation by additional investigation and risk assessment and most likely to lie between no possibility of harm (under current conditions) and significant possibility of significant harm (under conditions created by new use). Remediation may be required for redevelopment. Low risk Potential pathways and receptors exist but history of contaminative use or site conditions indicates that contamination is likely to be of limited extent and below the level of no possibility of harm. Precautionary investigations and risk assessment advisable on change of use. Very Low Risk No pollution linkage likely to exist under current or future conditions. Site not capable of being determined under Part 2A (in accordance with PPS23) where the Local Authority inspects the site. No further action recommended.

Contaminant Analysis of Samples

CLR 8 (Environment Agency 2002b), the DoE Industry Profile documents and ISO10381-5 provide good summaries of priority pollutants for UK sites. Additionally, the Environment Agency has produced a list of priority pollutants for ecological risk assessment in a consultation document (Environment Agency 2003a). These documents have been used, with the findings of the Phase 1 investigation, to scope the analyses of chemicals of potential concern.

Grange Geo considers there to be a minimum requirement for soil chemical analysis, even for Greenfield sites, to satisfy the ‘suitable for use’ criterion of the planning regime. The GACs adopted by Grange Geo for the Site are given in the following table.

There is no safe acceptable level for asbestos in soils, detect or non-detect is recorded with asbestos quantification undertaken on samples found to contain asbestos.
