1 Introduction

1.1 Background and Purpose of Our Works

We have been commissioned by Wycombe District Council (the Council) to complete a site characterisation exercise and Detailed Quantitative Risk Assessment for the Bassetsbury allotment site, located off Bassetsbury Lane to the east of High Wycombe town centre.

During 2008 a limited ground investigation was completed at the site, commissioned jointly by the Council and a property developer, the St James Group Ltd. The results of this investigation identified concentrations of potential contaminants that exceeded generic screening criteria for residential end use in several of the soil samples analysed.

Subsequent soil investigations were commissioned at the site, which all identified further isolated soil samples containing concentrations of potential contaminants in excess of generic acceptance criteria for residential or allotment uses. On the basis of the works previously completed and the potential contamination issues identified, insurance cannot currently be secured for the site. As such the Council is unable to lease the plots to tenants for allotment use and was forced to close the site.

Having reviewed the various site data available and also considering the current issues we devised a strategy for the site based on completing a detailed site characterisation exercise and risk assessment. Our strategy was designed to achieve the following objectives:

Ø To complete a detailed characterisation of soil conditions across the actual allotment plots that the Council have historically based their leasehold agreements on. This was based on the assumption that potential risks posed to site users are predominantly derived from the soils in which they physically come into contact with and grow plants in;

Ø To remove possible ambiguity in site data by providing a highly robust sampling set;

Ø To generate sufficiently robust conclusions regarding each of the allotment plots such that clear decisions could be made with regard the future of the site. The ideal objective would be to secure provision of suitable (and affordable) insurance for ongoing allotment uses to Wycombe District Council to allow the future letting of leases to allotment holders. Conversely, in the event that significant contamination were encountered, to allow detailed and highly focused remedial options to be assessed; and finally

Ø To provide an assessment strategy for the site that is easy to understand and fully transparent to all parties. The use of an extensive grid based sampling strategy is easy for the layman to understand, preventing potential accusations of strategic assessment, and allows for easy visual presentation of site data.

Our detailed site characterisation and risk assessment strategy was presented to the Council in the form of a competitive tender for the detailed assessment of the Bassetsbury allotments site.

All the activities comprising this assessment were carried out in accordance with the procedures set out in our Quality Manual. Your attention is drawn to the Notice to Interested Parties included as Attachment One.

1.2 Scope of Our Works

The scope of works that we have completed was as follows:

Ø Construction of a network of shallow boreholes across each designated allotment plot at approximately 5m centres, resulting in the construction of approximately ten sampling locations per plot. A total of 184 boreholes were constructed to 1m depths across the site using our Terrier dynamic probing drill rig over the course of a two-week fieldwork phase. Soil samples were recovered at approximately 0.2-0.3m depths and at ~0.7m depths from each borehole.

Ø All sample locations were surveyed using GPS surveying equipment to allow the development of a detailed contamination distribution plot.

In12855 CL 002 Page 4


Ø Soil samples from each borehole were analysed for a suite of heavy metal compounds. Selected soil samples from every plot were analysed for polyaromatic hydrocarbons (PAHs) and additional samples were analysed for Total Organic Carbon (TOC) and pH. Our chemical analysis strategy was based on the results of the previous investigation works and identified contaminants.

Ø Statistical analysis of the comprehensive site data and completion of a Detailed Quantitative Risk Assessment for the site.

Ø Provision of this Site Characterisation and Detailed Quantitative Risk Assessment Report, detailing the findings of our assessment works.

2 Site Description and Setting

2.1 Site Description

The site is located at National Grid Reference 488092 191988 at approximately 65m above Ordnance Datum. It is situated on Bassetsbury Lane, approximately 1km to the south and east of High Wycombe town centre.

The site comprises an irregular shaped plot that has been historically allocated for allotment use. The site itself is generally level, although the surrounding land levels drop steeply from the western end, suggesting that the site levels have potentially been made up in the past. There are a total of twenty allotment plots that were leased to tenants by the Council, occupying the majority of the site. The eastern end of the site is used by the Council as a storage depot for various landscaping materials (aggregates, wood chippings etc) and also for composting of green wastes from other Council open space areas.

A map showing the sites locality is shown as Figure One, below, and an aerial photograph showing the site layout is provided overleaf.

North

The north eastern boundary of the site is formed by a tree lined former railway embankment, beyond which is a large residential development (on former sewage works land). Directly north of the site (~150m) are commercial / retail warehouses

along London Road.

East Generally residential to the east and south east. London Road is present approximately 250m to the east, with various retail and commercial properties.

South Residential properties are located along the southern side of Bassetsbury Lane. Woodland beyond, with the land rising steeply.

West Residential properties to the west and south west. Levels drop beyond the north

western edge of the site by approximately 2-3m into an undeveloped area (nature reserve). There is a large pipeline to the immediate west of the site.

3 Review of Previous Environmental Investigation Data

3.1 Previous Environmental Investigation Works

Since the initial environmental investigation that highlighted potential contamination issues at the site was completed in 2008, several phases of environmental assessment and risk assessment have been completed. Works have been commissioned by the Council and also by the Bassetsbury Lane Allotment Group (BLAG), comprising the allotment holders themselves.

We were provided with copies of all the previous investigation and assessment reports. We have reviewed these documents and a brief summary of the works completed and conclusions reached is provided in the following table.

Sampling of top soil, root/tuber and shoot crops from selected allotments.

Analysis of samples for cadmium.

Comparison of results against published Soil Guideline Values and European Food Standards Agency values.

None of vegetation samples contained levels of cadmium in excess of relevant guidelines. Soils to plant transfer factors were therefore lower than the default CLEA guidance.

Concluded that the land is likely to be suitable for allotment use, with addition testing recommended for Plot 2.

Table Two: Summary of Previous Environmental Assessment Works – Bassetsbury Allotments (continued)

3.1.1 Comment on works completed to date

With respect to the works completed at the site to date, we would make the following comment:

Ø We consider the initial RSK report to represent a highly conservative assessment of site conditions. The conclusions reached and recommended remedial action appear excessively conservative given only eight soil samples were submitted for chemical testing. We also note that the investigation scope was to assess for residential redevelopment and all recommendations made focus solely on preparing the site for residential redevelopment. The conclusions of the report may therefore not be valid, as no assessment for allotment use was completed.

In12855 CL 002 Page 8


Ø Both the RSK and Jacobs assessment works included comparison of the chemical analysis results against 2002 Soil Guideline Values and/or Generic Acceptance Criteria generated from the original CLEA model, both of which have been replaced. The conclusions of these original 2009 reports are, therefore, effectively invalid.

Ø We would consider that the most detailed assessment of site conditions completed to date comprises the URS review. This includes assessment of chemical data from a total of 44 soil samples against updated Soil Guideline Values and/or Generic Acceptance Criteria derived using the 2009 CLEA guidance.

Ø We note that the conclusions of the Mayer review, URS assessment and Reading University study, while offered with caveats, generally indicate that the site is considered to be suitable for continued allotment use. We understand that it is the lack of definitive conclusion that resulted in the Council’s insurers withdrawing cover for the site.

Ø As the URS report points out, the data generated from all soil sampling completed since 2008 still only represents a total of 24 sampling locations across the entire site. This has been calculated to represent a sampling grid density of approximately 25m x 25m. Given the potential risks being posed to the allotment holders, we consider this sampling density is inadequate and directly results in the extremely conservative conclusions being drawn.

Ø We concur with the URS recommendation that additional site assessment should be completed at the site. Much of the assessment of contamination, and especially heavy metal contaminants, relies on statistical analysis of data to ensure a reasonable assessment of potential risk is being completed. With limited sampling numbers, any risk assessment inevitably becomes more conservative and potentially misleading. We therefore considered more robust sampling of the allotment plots would be the only way to provide any form of conclusive risk assessment for the site.

4 Site Characterisation Works

4.1 Site Characterisation - Design and Rationale

4.1.1 Key Objectives

We devised a strategy for the site based on completing a detailed site characterisation exercise and then undertaking a detailed risk assessment, effectively for each allotment plot, using the site data. Our strategy was designed to achieve the following objectives:

Ø To complete a detailed characterisation of soil conditions across the actual allotment plots that the Council have historically based their leasehold agreements on. This was based on the assumption that potential risks posed to site users are predominantly derived from the soils in which they physically come into contact with and grow plants in;

Ø To remove possible ambiguity in site data by providing a highly robust sampling set;

Ø To generate sufficiently robust conclusions regarding each of the allotment plots such that clear decisions could be made with regard the future of the site. The ideal objective would be to secure provision of suitable (and affordable) insurance for ongoing allotment uses to Wycombe District Council to allow the future letting of leases to allotment holders. Conversely, in the event that significant contamination were encountered, to allow detailed and highly focused remedial options to be assessed; and finally

Ø To provide an assessment strategy for the site that is easy to understand and fully transparent to all parties. The use of an extensive grid based sampling strategy is easy for the layman to understand, preventing potential accusations of strategic assessment, and allows for easy visual presentation of site data.

In12855 CL 002 Page 9


4.1.2 Investigation Strategy

Our proposed strategy for the initial site characterisation works comprised the detailed assessment of shallow soils across each specific allotment plot at the site by completing a comprehensive grid based sampling exercise. Our proposed methodology comprised:

Ø Construction of a network of shallow boreholes across each designated allotment plot at approximately 5m centres, resulting in approximately ten sampling locations per plot.

Ø All sample locations surveyed using GPS surveying equipment to allow the development of a detailed contamination distribution plot.

Ø Boreholes constructed to approximately 1.0m depths with soil samples recovered from each sampling location at depths of 0.2 – 0.3m (targeting top soils) and also from 0.7 - 0.8m (targeting underlying deeper soils and/or reported Made Ground material).

Ø Soil samples from each borehole to be analysed for a suite of heavy metal compounds. Selected soil samples from every plot were analysed for polyaromatic hydrocarbons (PAHs) and additional samples were analysed for Total Organic Carbon (TOC) and pH. Our chemical analysis strategy was based on the results of the previous investigation works and identified contaminants.

Ø The extensive site data obtained to be used to complete a Detailed Quantitative Risk Assessment for the site, effectively broken down to comprise an assessment of each individual plot.

4.2 Works Completed

We completed our site characterisation works at the site during a single phase of site work completed between the 7th May and the 17th May.

We understand that the site has been formally closed for allotment use since 2009. The site is, for the most part, heavily overgrown although there was evidence of continued allotment use on a number of the plots, with several showing signs of ongoing cultivation and maintenance.

We reviewed the existing site plans that we obtained from the previous reports and completed a detailed visual survey of the site to identify the plot boundaries based on the location of clear footpaths, storage sheds, raised beds, mature plants and evidence provided by former allotment holders / members of public who approached us during our works. We then surveyed the plot boundaries based on our field evidence and marked out proposed borehole locations.

We drilled a total of 184 shallow boreholes across the site using our tracked Terrier dynamic sampling drilling system. Soil cores were logged and sub-sampled on site and the borehole locations surveyed using our GPS surveying equipment.

A site plan showing the allotment plot boundaries that we allocated and the locations of our various boreholes is provided overleaf.

4.4 Discussion

Generally, the underlying geology we encountered across the site comprised a thin layer of top soil overlying Made Ground material of variable composition and quality. The thickness of top soil was generally recorded as 0.3m to 0.5m and we noted mixing of the underlying Made Ground with the shallow top soil in several locations (evidenced by the presence of brick fragments or other debris).

We encountered buried mass concrete or brick rubble in several areas of the site at shallow depth, preventing the construction of boreholes to 1m depth. We encountered visual and/or olfactory evidence of potential sources of contamination in a number of the boreholes we constructed. Tarmac fragments and black stained sands (possible tarry) were identified in the underlying Made Ground materials in many of the boreholes, with clinker and/or ash material also encountered occasionally. A site plan showing the locations where visual evidence of potential contamination and/or mass concrete was encountered is provided overleaf as Figure Two.

From our observations, it would appear that the site levels have been made up in the past using imported Made Ground materials of a relatively industrial nature.

In12885 CL 002 Page 19


4.5 Chemical Analysis – Soil Samples

Based on the previous investigation data and contaminants identified at the site, we submitted the following soil samples for chemical analysis:

Ø A total of 346 soil samples were submitted for analysis for a suite of heavy metal compounds comprising arsenic, barium, beryllium, water soluble boron, cadmium, chromium, copper, lead, mercury, nickel, selenium, vanadium and zinc.

Ø A total of 96 soil samples were submitted for analysis for Polyaromatic Hydrocarbons (PAH);

Ø A total of 40 soil samples were submitted for Total Organic Carbon (TOC) and pH.

We have used the results of our chemical analysis to undertake our detailed risk assessment for the site. Full laboratory analysis certificates are provided at Attachment Two.

5 Conceptual Site Model

5.1 Introduction

We have used the data reviewed above to construct a conceptual site model, shown graphically in Figure Three below.

Figure Three: Conceptual Site Model for Allotment Site

In12885 CL 002 Page 20


5.2 Sources

The chemical analysis results recorded by this and previous investigations (Refs.1, 2, 4) identified elevated concentrations of various heavy metals and PAHs in shallow soil at the site.

5.3 Receptors

The aim of this investigation is to determine whether the site is suitable for ongoing use as allotments, following current industry guidance and methodologies. The receptors considered in our assessment are therefore allotment owners/users, including any children who may visit the allotments on a regular basis.

5.4 Pathways

Information from previous reports indicates that Bassetsbury Allotments is a ‘typical’ allotment site and we have no information to indicate otherwise. As such we consider that the site can be reasonably represented by the CLEA allotment land use scenario detailed in report SR3 (Ref.9).

We have identified the following potentially viable source-pathway-receptor linkages at the site.

Source Receptor Pathway

Consumption of fruit and vegetables grown on the allotment

Dermal contact, ingestion of and inhalation of soil and dust

Elevated concentrations of the various heavy metals and PAHs identified in soil

Allotment owners and accompanying children

Inhalation of vapours in outdoor air

6 Data Screening

6.1 Assessment Criteria

Our assessment of the potential risk posed by soils to allotment holders requires comparison of recorded concentrations against an acceptable or critical concentration. We have used the following sources in order of preference as for our critical concentration:

Ø Environment Agency Soil Guideline Values;

Ø LQM CIEH Generic Assessment Criteria (GACs);

The GAC for benzo(a)pyrene is sensitive to the amount of organic matter in the soil. We have therefore analysed a total of 40 soil samples from across the site for Total Organic Carbon content in order to ensure that our assessment was completely relevant to the site.

The average value for total organic carbon recorded in site samples is 2.1%. This is roughly equivalent to 3.6% soil organic matter. As GAC values have been calculated for 1%, 2.5% and 6% soil organic matter, we have therefore used the published GACs for soil organic matter of 2.5% for benzo(a)pyrene.

The selected criteria for each contaminant are presented in Table Five below.

6.2 Initial Review of Analytical Data

We have carried out an initial review of site data. This allows us to screen out any contaminants or plots which are unlikely to pose a significant risk to allotment users.

We have combined our analytical data with the previous results provided within reports by RSK (Ref.1), Jacobs (Ref.2) and URS (Ref.4) to create a single data set.

In12885 CL 002 Page 21


The recorded concentrations of each contaminant have been compared with the relevant critical concentration. Where all recorded concentrations are below the critical concentration the contaminant is considered to pose no significant long-term risk to allotment users and no further assessment is required.

Where concentrations exceeding the critical concentration have been recorded, this does not necessarily mean there is a risk to allotment holders, but further assessment is required to determine whether the recorded concentrations pose a potential risk to allotment users.

As discussed in our objectives, we have assessed the data for each allotment plot separately. For the contaminants identified in Table Five as requiring further investigation, we have determined which individual plots are contain concentrations of each compound in excess of the critical concentration. These plots and contaminants have then been assessed further in our detailed quantitative risk assessment.

For each plot, the marked contaminants require further investigation to determine whether they pose a potential risk to allotment users. Other plots/contaminants are not considered to pose a significant risk to allotment users.

7 Detailed Quantitative Risk Assessment

7.1 Methodology

The aim of our risk assessment is to determine whether the allotment plots are ‘safe’ to use, and to provide sufficiently robust evidence of this, which will enable the Council to obtain suitable insurance cover for on-going use of the site for allotments.

In assessing contaminants at a site, we are generally interested in the mean, or average, concentration of contaminants, as this provides a reasonable guide to the amount of exposure that an individual will experience over a long period of time.

In12885 CL 002 Page 23


As we can’t examine every part of the soil to determine the true mean concentration, we have to rely on sampling data to provide an estimate of the mean concentration. We then use statistical analysis to determine, based on the site data we have collected, the likelihood that the true mean concentration of the contaminant is above or below the certain ‘critical concentration’.

We have carried out statistical analysis in line with current UK guidance (Ref.11). This is undertaken in the following stages:

i. Consider the legal context of the assessment, which determines the approach we take to assessing the data.

ii. Review whether the data is suitable for statistical testing to be applied. Statistical tests should only be applied to data that is representative of the whole of the area of interest.

iii. Create a suitable data set. To do this we need to look at a number of factors:

Ø Identification of samples with non-detect values. If these make up a large proportion of the data set they can skew the results of the statistical testing and therefore a decision must be made regarding what value to assign to non-detect samples.

Ø Identification of outliers (data points that lie outside the normal distribution range for the site) and consideration of how to deal with these. There may be several reasons for an outlier: a) it may be the results of an error in analysis or transcription, b) it may indicate that there are two ‘populations’ of soil at the site (e.g. an area of higher concentrations and an area of low concentrations), or c) it may be an extreme value in the actual range of concentrations on site.

The guidance indicates that unless there is clear evidence to show the outlier is due to an error or a separate soil population, outliers should be assumed to be part of the range of concentrations on site that site users may be exposed to and should be included in the analysis. We have used a test called the Grubb Test, detailed in the guidance, to identify outliers.

Ø Determining the distribution of the dataset. Statistical tests make assumptions about how the dataset is distributed. For this assessment, we need to determine whether data is normally distributed or not. We have done this using ‘probability plots’ of the dataset.

iv. Apply the relevant statistical test. The guidance indicates that if the dataset is normally distributed, a test called the one-sample ‘t-test’ should be used, otherwise a test called the ‘Chebychev test’ should be used.

iv. Evaluate the outcome of the statistical testing.

7.2 Legal Context and Approach

The guidance sets out two possible approaches to completing statistical assessment of contaminants at a site, which reflect the reason for the assessment:

i. The planning scenario. This test is about showing there is a high probability that the true mean contaminant concentration on site is below the critical concentration. This approach is aimed at protecting site users from harm.

ii. To determine whether land falls within the scope of Part 2A of the Environmental Protection Act 1990. This test is about showing there is a high probability that the true mean concentration is above the critical concentration. This approach is aimed at identifying ‘contaminated land’ as defined by the Act.

In a previous assessment URS (Ref.4) selected the Part 2A approach as appropriate because no land use change was proposed and no planning permission was required at the site. However this approach is aimed at determining whether land is ‘contaminated’, but does not consider whether it is suitable for the proposed end use.

At this site we are not trying to determine whether there is a high probability that the land can be classified as contaminated, rather we are trying to determine whether it is safe to be used as allotments and therefore we consider the ‘planning’ scenario to be appropriate at this site.

In12885 CL 002 Page 24


If the site passes, we can be confident that allotment holders are not being put at significant risk and that there should be sufficient evidence to enable the Council to obtain insurance, which will allow the allotments to continued to be used.

The planning scenario approach examines the key question: Is there sufficient evidence that the true mean concentration of the contaminant is less than the critical concentration?

Our Null Hypothesis (H0) can therefore be stated as: The true mean contaminant concentration is equal to, or greater than, the critical concentration.

Therefore our Alternative Hypothesis (H1) is stated as: The true mean contaminant concentration is less than the critical concentration.

We have conducted tests at the 95% confidence level as recommended in the guidance. This means the chance of the decision being wrong is less than 5%, providing confidence for both insurers and allotment users that use of the site is suitable for use as allotments.

7.3 Creation of Data Sets

7.3.1 Data suitability

Our sampling strategy was designed to provide systematic and unbiased sampling data which is therefore suitable for use in the statistical tests outlined in the UK guidance (Ref.11).

7.3.2 Data Sets

As discussed above, data has been grouped by allotment plot and includes both our analytical data and that provided in the three reports references in Table 2 (Ref.1, 2 and 4). Where further assessment is required and sufficient data points are available, data has been sub-divided within each plot into shallower and deeper data sets within each plot to reflect the two soil horizons identified on site.

7.3.3 Dealing with non-detect data

Non-detects (where concentrations of a given contaminant were not detected in excess of the relevant laboratory method detection limit) comprise less than 15% of the majority of data-sets. For these data-sets we consider it appropriate to assign a value of half the detection limit to the non-detect results, in accordance with the CL:AIRE/CIEH guidance (Ref.11).

For data-sets where non-detects comprise more than 15%, notably benzo(a)pyrene in one plot and cadmium in all plots, we have assigned a value of half the detection limit to the non-detects, but have carried out a sensitivity analysis to determine the robustness of the statistical testing for the data set.

7.3.4 Dealing with outliers

The following table summarises the plots in which we identified outliers.

Contaminant Plots with outliers Plots with no Outliers

Table Seven: Location of Identified Outliers

In12885 CL 002 Page 25


The CL:AIRE/CIEH guidance recommends that outliers should only be excluded from a dataset where they are clearly the result of an identifiable error or where data indicates that there is more than one soil population within the dataset.

We have found no significant evidence in the site observations and sample descriptions to support removal of these outliers from the relevant data sets. Moreover, the fact that outliers are present in the majority of data-sets for cadmium, copper lead, zinc and benzo(a)pyrene suggest that these values are not errors but are a feature of the contaminant distribution at the site.

Therefore in line with the guidance we consider that the higher concentrations represent part of the normal range of concentrations that receptors may be exposed to and have not been removed from data-sets.

7.3.5 Data Distribution

The distribution of data and statistical tests used are shown in the statistical data sheets included in Attachment Three.

7.4 Results and Evaluation

We carried out an assessment using the full data-set for each allotment plot. The results, summarised in Table Eight below, indicate that cadmium, vanadium and benzo(a)pyrene pose a significant risk in a large number of plots across the site. Other contaminants posed a risk in a number of individual plots.

Whilst contaminants present in individual plots could potentially be dealt with by carrying out localised remedial work at the site, the more widespread contaminants would indicate that the site as a whole is unlikely to be suitable for use as allotments. We therefore focused further assessment on these contaminants to determine whether it was possible to draw alternative conclusions regarding the risk posed.

The statistical worksheets are included in Attachment Three.

7.4.1 Assessment of Separate Soil Layers

To further investigate the risk posed by cadmium and vanadium and to determine whether we could draw alternative conclusions, we reassessed the data by looking at the topsoil data and made ground data separately.

The results of the reassessment are included in Table Eight, overleaf. As can be seen from the data, the reassessment had very little effect of the overall results, indicating that cadmium and, in particular, vanadium is present throughout both soil layers at relatively high concentrations.

We did not complete a more detailed reassessment of the benzo(a)pyrene data using the two soil layers approach, as we have much smaller data-sets for each plot.

7.4.2 Sensitivity Analysis for Non-Detects

All of the data sets for cadmium and two of the data-sets for benzo(a)pyrene contained a large percentages of non-detects. In our initial assessment we assigned a value of 50% of the limit of detection to all non-detect samples.

We then carried out sensitivity analysis for the data-sets containing a high percentage of non-detects, assigning a value of 10% of the limit of detection to non-detect samples to determine whether this generated an alternative results.

The results for cadmium in Plot Five changed from a marginal pass to a marginal fail. All other results were unchanged, suggesting that our original chosen criteria for non-detect data was generally suitable.

1 We have insufficient data points in each dataset for benzo(a)pyrene to split the dataset further into shallow and deep layers.

7.5 Zoning and Contaminant Distribution

For those contaminants that have been identified as posing a risk in a large number of the plots, specifically cadmium, vanadium and benzo(a)pyrene we have plotted the distribution of contaminants across the site. The plots are shown in Figure Four to Six on the following pages.

The aim was to identify any areas of the site where contaminant concentrations are lower then average with a view to possibly re-zoning the site and relocating allotment plots in less contaminated areas.

Figure Six: Vanadium Concentration Plots in Shallow and Deep Soil

In12885 CL 002 Page 30


As can be seen from the contamination distribution plots:

Ø Cadmium is primarily present across northern and western areas of the site. However other contaminants are present in high concentrations relative to the critical criteria across much of the site.

Ø Vanadium, in particular, was recorded at concentrations in excess of the critical criteria in 75% of samples indicating a widespread problem, not limited to specific areas of the site. Vanadium is present in both shallow and deep soil across the majority of the site, with higher concentrations present in the shallow soil.

Ø The plots indicate the benzo(a)pyrene concentrations in shallow soil pose a risk only on the eastern part of the site. However, in deeper soils, benzo(a)pyrene concentrations were generally found to poses a risk across the rest of the site. This is almost certainly due to the tarmac component of the underlying Made Ground material that we encountered across the site.

Generally, the areas of impact of the various contaminants overlap and we have not been able to identify any areas of the site where concentrations of all compounds are below the critical concentrations. On the basis of our assessment of contamination distribution, we conclude that re-zoning land uses on the site will not enable us to identify suitable plots for allotment use.

8 Discussion and Conclusions

8.1 Possible Sources of Identified Contaminants

We have reviewed potential sources of the key contaminants we have identified at the site.

Contaminant Natural Sources Anthropogenic Sources

Vanadium Weathering of vanadium rich rocks. Found at ~15mg/kg primarily in the Americans, Africa and Australasia

Widespread industrial use, mainly metallurgic and metal work industry, also burning of fossil fuels and disposal of ash.

Cadmium Include volcanic activity an forest fires

By product from processing of zinc, it is also used in batteries, pigments and a range of other industrial uses.

Other contaminants which were present across the site include copper and zinc which are also often associated with metal smelting activities.

Benzo(a)pyrene Natural fossil fuel depots, usually found at depth. Volcanic eruptions and forest fires.

Coal, tar, asphalt, roofing tar. Aluminium iron and steel production.

Also produced by the incomplete combustion of organic materials.

Table Nine: Possible Sources of Contaminants of Concern

We consider that all of the key contaminants identified are connected to metal production or processing, which may indicate the source of the underlying Made Ground material that we encountered. However, as the contaminants are associated with a wide range of industrial and commercial processed the exact source cannot be identified.

On balance, and taking into account the appearance of the Made Ground material we encountered (visible ash and tarry material encountered, along with mass concrete and brick) we consider it most likely that the contaminants identified result from anthropogenic sources.

In12885 CL 002 Page 31


8.2 Statistical Assessment

Our statistical assessment identified at least one contaminant on every allotment plot that was determined to pose a significant risk to allotment users.

As we noted previously, statistical outliers were identified in a large number of datasets. In some cases the outlier was the only reason the plot ‘failed’ the assessment. However as these outliers were recorded in a large number of plots they appear to be part of the distribution of the contaminant concentrations and therefore cannot be excluded as isolated hotspots.

For example, in the case of benzo(a)pyrene many of the outliers were most likely associated with tarmac fragments which were observed in shallow soil across many parts of the site. This would therefore indicate that the source of benzo(a)pyrene is widespread (i.e. tarmac fragments are fairly evenly distributed throughout the soil) and it is unlikely that this source can be removed by selected excavation.

We have used industry standard Soil Guideline Values and General Assessment Criteria to complete our risk assessment. As noted in the HPA review of previous assessment reports (Ref.5), these criteria are based on a soil organic matter of 2.5% and a soil type of sandy loam. As this is not fully reflective of site conditions, the HPA recommended that further work might be required derive more site specific criteria. The HPA made a number of other additional suggestions that could provide more site specific assessment criteria.

However, given the extent of the contamination, both in terms of wide distribution across the site and high concentrations relative to published compliance criteria, we do not consider there is any benefit to carrying out more detailed and site specific analysis as any change in individual outcomes is likely to be marginal and not likely to effect the overall conclusions we have drawn regarding the suitability of the site for allotment use.

8.3 Conclusions

On the basis of the findings of our investigation and detailed risk assessment, we consider that the site is not suitable for use as allotments.

Due to the nature of the underlying Made Ground material and based on the distribution of contaminants we have encountered we also conclude that there is unlikely to be a cost effective remediation solution for the site.

We do not consider re-zoning of site use and/or localised remedial excavation and replacement of shallow soils will be sufficient to provide adequate protection to future allotment holders. Suitable remediation strategies would require extensive excavation of the contaminated soils and/or Made Ground, placement of capping layers and importation of suitably inert top soils to a thickness sufficient to allow plant growth.

NOTICE TO INTERESTED PARTIES The purpose of our target levels is to determine site-specific concentrations of soil and/or groundwater that will not pose a toxicological risk to identified on-site and off-site receptors.

Where stated in this report, we have used information supplied by third parties. While we have evaluated as far as possible the validity of this information, we cannot guarantee its accuracy in any way whatsoever.

When examining the voracity of the base data used in our assessment, we would make the following comments. No investigation technique is capable of completely identifying all of the contaminants that might be present in the soil or groundwater under a site. Where specified in our report, we have examined the ground by constructing a number of boreholes and/or trial pits. We recovered samples of soil and/or groundwater from available exposures. The depth and spacing of our sampling locations were selected to ensure with a reasonable probability that they would be representative of the actual conditions across the whole site.

Soil is, however, intrinsically variable and the spread of contaminants within the soil is therefore subject to a degree of non-uniformity. For these reasons no sampling technique can completely eliminate the possibility of obtaining samples that are not representative of the actual conditions. Our sampling techniques have simply reduced the possibility to an acceptable level.

Groundwater levels and soil vapour levels that we report were accurate at the time of the investigation. Groundwater and soil vapour levels are variable. Long term monitoring may be required to ensure that the levels recorded during our investigation are representative of long term and possible ‘worst case’ conditions.

This investigation was carried out to assess the significance of contamination resulting from use of the site as identified in this report. Unless we have indicated otherwise, no assessment of the potential impact of any other previous uses has been made. No investigation was carried out to determine whether or not any deleterious or hazardous materials have been used in the construction of the buildings present on the site.

We do not accept any responsibility for the cost of remedial works or other costs incurred in whatever way whatsoever as a result of any omissions, errors or other shortcomings in this report unless we have been given reasonable opportunity to verify ourselves that such faults exist and we have been given a reasonable opportunity to carry out works to remedy such faults ourselves using the most practicable means available to us. We do not accept liability for any consequential losses incurred by you while we carry out any remedial works we deem necessary. This report has been prepared for Wycombe District Council. Use of, and reliance on, this report by other third parties will be at such third parties own risk, and we are unable to accept any liability or responsibility to third parties. Neither the whole nor any part of this report, or any reference to it, may be included in any published document circular or statement or published in any way without our prior written approval.

Notes - not for inclusion in print outSee Appendix B1 for test

Select appropriate value of Tcrit for n value from Table B1

Do probability plot without outliers if necessary and decide which to use…..If plot is non-normal does this matter - do we have enough data to determien this - what does
