If there is a Site History that indicates industrial usage then it may
be necessary to carry out a Phase 2 Site Investigation. This involves
taking soil samples from site and sending them to a laboratory for
testing. A Site Contamination Assessment Report can then be assembled.
Example Site Investigation
If test results are in compliance with limits outlined under Part IIA of
the Environment Act then no further action is needed. If however limits
for contaminants are breached then further
remedial action will be
needed.
Sampling:
Samples can be taken from site in a
number of ways including Trial Pits (machine or hand-dug), or by
percussion sampling methods. For retrieval of geotechnical
samples, or installation of monitoring wells more advanced equipment may be needed.
Whilst the equipment is on site, it is wise to take further
samples for geotechnical testing, this can be arranged by
Southwest Environmental. (Soil strength values and
Classification etc)

EA releases "Guiding Principles for Land Contamination"
Te EA has released a collection of "guidance that replaces our
document ’Environment Agency requirements for land contamination
reports’." The guidance is aimed at land owners, specialists and
consultants and clarifies the governments stance on dealing with
the large areas of contaminated land in the UK.
At Southwest Environmental Limited we pride
ourselves on providing quality data, Only approved Site
Investigation Contractors will undertake works on site. BH
Positioning will be carried out by qualified surveyors to ensure
accurate elevations. Chain of Custody will be maintained for all
soil samples between site and labs.
Testing is carried out by a third party UCAS accredited laboratory.
SWEL uses a detailed Suite Tests to determine which contaminants
are present in the soil samples.
On site GAS Monitoring may also be performed, which will measure
both the composition and quantity of gas emanating from the
ground.
Testing for VOCs cam also be arranged.

includes the factual data collected, and recommendations for further
action (if necessary). SWEL uses DEFRAs
CLEA Model to assess risk to
near by receptors.
