FOREWORD
General Conditions Relating To Site Investigation
This investigation has been devised to generally comply with the relevant principles and requirements
of B.S.10175:2011+A1:2013 ‘Investigation of potentially contaminated sites - Code of practice’,
science report SC050021/SR3 ‘Updated Technical Background to the CLEA Model’ (Environment
Agency, 2008), and Contaminated Land Report 11 ‘Model procedures for the management of
contaminated land’ (Department for Environment, Food and Rural Affairs and the Environment
Agency, 2004). The recommendations made and opinions expressed in this report are based on the
information obtained from the sources described using a methodology intended to provide
reasonable consistency and robustness.
The opinions expressed in this report are based on the ground conditions revealed by the site works,
together with an assessment of the site and of laboratory test results. Whilst opinions may be
expressed relating to sub-soil conditions in parts of the site not investigated, for example between
exploratory positions, these are only for guidance and no liability can be accepted for their accuracy.
Boring and sampling procedures are undertaken in accordance with B.S.5930:1999+A2:2010 ‘Code
of Practice for Site Investigations’. Likewise in situ and laboratory testing complies with B.S.1377:1990
‘Methods of Tests for Soils for Civil Engineering Purposes’, unless stated otherwise in the text.
Chemical Testing has been undertaken by UKAS accredited laboratory.
The groundwater conditions entered on the boring records are those observed at the time of
investigation. The normal rate of boring usually does not permit the recording of an equilibrium water
level for any one water strike. Moreover, groundwater levels are subject to seasonal variation or
changes in local drainage conditions.
Some items of the investigation have been provided by third parties and whilst Harrison Group have
no reason to doubt the accuracy, the items relied on have not been verified. No responsibility can be
accepted for errors within third party items presented in this report.
This report is produced for the benefit of the client alone. No responsibility can be accepted for any
consequences of this information being passed to a third party who may act upon its
contents/recommendations.

SITE INVESTIGATION REPORT
FOR A SITE AT
YARMOUTH ROAD, BLOFIELD
1 TERMS OF REFERENCE & INTRODUCTION
The work covered by this report was undertaken on behalf of A J & R Smith prior to the planned
residential development of the site, shown on appended drawing GN18104-DR001 and located off
Yarmouth Road, Blofield, Norfolk. The centre of the site can be identified by National Grid Reference
632890, 309560.
This report was designed to aid in the planning process, specifically to Broadland District Council
planning application 201111303.
An initial phase one desk study report (contaminated land investigation) has previously been undertaken
for this site by MLM Environmental (722770/R2 dated September 2010). This assessed a very low risk
from contamination although stated that the local authority may require some limited soil sampling and
testing to provide further assessment.
Broadland District Council had reviewed this report and subsequently requested that some further
intrusive investigation be undertaken for a small parcel of the site (southern site area) where it had been
previously used as a car parking area for a ‘pick-your-own’ site. This report refers only to this area
(shown within the red investigation boundary on the attached drawings) and encompasses the findings
of the ground investigation fieldwork, soil chemical testing and further assessment of the risk from
contamination.
The investigation is in accordance with Harrison Group Environmental Limited’s quotation dated 23rd
January 2014 with an emailed instruction from the client dated 24th
January 2014.
The investigation was carried out using available published documentation and MLM Environmental
Preliminary Contamination Assessment Report, in association with an in-situ investigation.
2 BACKGROUND INFORMATION
The environmental setting background information (geology, hydrology, hydrogeology and database
information) and site history have been researched as part of this report. A summary of the
environmental and geological setting is given in the following sections.

The site is located within a groundwater source protection zone (SPZ) 3,
indicating it lies within the total catchment. An outer zone, SPZ 2, lies
approximately 1km to the south, and an SPZ 1 1.4km to the south,
indicating the direction of groundwater flow may be to the south.
The nearest surface water feature is the River Wensum flowing east,
located over 1.5km to the south. There are no significant surface water
features within 250m of the site.
The site is not considered to be at risk from flooding.
Table 1: Background Information
2.2 Site History
The history of the overall site has been previously summarised in the Preliminary Contamination
Assessment Report by MLM Environmental. The larger site area was summarised as being used as
arable farm land with no previous development within the time zone studied. A haulage depot and car
dealership was noted located immediately to the west of the site although were assessed to be of very
low contamination risk to the site.
Recent correspondence the local authority has revealed that the area to be investigated (a small portion
of the southern site) has more historically been used as a temporary car park for a ‘pick-your-own’ site.
3 HAZARD IDENTIFICATION AND ASSESSMENT
Contamination hazard identification had been previously undertaken by MLM Environmental Preliminary
Contamination Assessment Report undertaken using source-pathway-receptor principles. The overall
risk to human health and other environmental receptors from the contamination sources identified
(fertilisers and pesticides from agricultural use and hydrocarbon compounds and organic vapours from
off-site sources) was considered very low.
The MLM report did not make mention of the potential contamination risk from the on-site car parking for
the former ‘pick-your-own’ activities. The associated contamination hazard from car-parking includes
hydrocarbons and organic vapours from fuel or oil leaks and spills from the parked cars. Although this
remains a low risk it was considered prudent to undertake some limited site investigation of this car
parking area to further assess this risk. This investigation is presented in the following section.
4 SITE INVESTIGATION FINDINGS AND RESULTS
4.1 Fieldwork Findings
Fieldwork was undertaken on 24th
January 2014 and included five hand augered boreholes (HA1-HA5),
the locations of which are identified on drawing GN18104-DR002. Hand auger records can be found
appended, which detail the soil profile encountered and the sampling regime.
It was initially proposed to undertake machine excavated trial pitting. However, upon commencement of
fieldwork, further information was provided detailing a future archaeological investigation at the site, and
therefore this necessitated replacing large scale pitting with hand augered boreholes.
In general, the site was underlain by made ground to approximately 0.8-1.0m, comprising dark brown
and dark grey gravelly sandy silty clay, with anthropogenic content including concrete and brick. This
corroborates the earlier suspicion that the site may include variable depths of made ground including
soils remaining from the disused car park. Natural soils were described as pale brown to brown silty clay
Harrison Group Environmental Limited
Report No GN18104_SI
www.harrisongroupuk.com February 2014 6
to termination depth of the boreholes between 1.5-1.9m, and are considered representative of the
Happisburgh Glacigenic Formation (Diamicton).
4.2 Soil Chemical Analysis and Assessment
Two samples of the made ground soils, HA1 ES2 (0.7-0.9m) and HA5 ES1 (0.0-0.2m), were submitted to
a UKAS/MCERTS accredited laboratory for a general suite of analytes including metals, PAH
compounds, hydrocarbons and an asbestos screen.
For an initial screening of soil chemical test results with regard to long-term human health risks, the
results have been compared to Site Assessment Criteria (SAC)/ Soil Guidance Value (SGV) as detailed in
table 2 below. Screening values have been published for a limited number of analytes by the EA for
standard land uses, including commercial and residential land use (with and without gardens). The
SGV/SAC for residential with plant uptake has been conservatively used.
Where contaminant concentrations are below the appropriate published figures, we can be confident
that no significant risk exists for the identified receptors. Where they exceed, a significant risk does not
necessarily exist, but more detailed assessment may be warranted to quantify the risk.

Table 2: Contamination Test Result Summary
Chemical test results illustrated concentrations of contaminants to be well below the conservative
screening criteria employed. Asbestos fibres were not detected in the two samples analysed.
4.3 Summary and Implications
The basic requirement for redevelopment standards in the UK is that land should be ‘suitable for use’ or
‘fit for purpose’, rather than apply a blanket ‘clean’ or ‘all uses policy’. It is important to consider the
limited nature of this investigation, and the possibility of as yet unknown contaminant sources existing.
The nature of the site history and uses we are aware of from our desk-based assessment and the
Preliminary Contamination Assessment Report conducted by MLM Environmental led to the preliminary
risk assessment of a generally very low risk from historic contamination. We highlighted the limited
potential for leaks and spills of fuels and oils which may have resulted from parked cars on the site.
We were requested to undertake a limited amount of sampling and analysis by the client and the
detected concentrations of metals, hydrocarbons and PAH compounds were below the levels of
concern. Harrison Group Environmental consider the material encountered to be chemically suitable for
use in residential development setting, and therefore does not to present an unacceptable risk to human
health or groundwater.
Whilst the site was thought suitable for development from the perspective of the potential for
contaminated land, we encourage ground and construction workers to be vigilant for the possibility for
further contamination thus far unidentified. Should visual or olfactory evidence be encountered, the
advice of a suitably qualified geoenvironmental engineer should be sought to discuss the appropriate
action with the local authority.
We recommend that the view of the Regulator be sought on the findings of this report, as part of the
planning process.
Harrison group Environmental Limited would be pleased to offer further assistance with the
recommended woks if requested, and if the client or regulators have any comments or questions we
would be glad to discuss them.
