Phase 2 - Geo-Environmental
Site Investigation
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.
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) |

Testing is carried out by a third party UCAS
accredited laboratory.
Reporting:
After the Information has been collected a report
is assembled, which includes the factual data collected, and
recommendations for further action (if necessary). SWEL uses DEFRAs CLEA
Model to assess risk to near by receptors.
