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.

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)
