Geotechnical and Contamination Investigations

Following a Phase I Desk Study and on producing a Conceptual Site Model it may be necessary to undertake an intrusive Phase II Investigation.

A Phase II Investigation can take many forms from simple sample collection to detailed intrusive investigations. Contamination Investigations are often completed for development sites which require compliance with planning conditions relating to contaminated land issues. For potential site acquisition/investment, the Phase II investigation provides a degree of assurance about potential soil and groundwater contamination issues to allow detailed risk and liability assessment to be undertaken.

We have experience of many types of former industrial sites including tanneries, petrol filling stations, breweries, vehicle repair garages, plating works and engineering workshops.

We can provide the following services:

Site investigation strategies
Attendance on site to complete intrusive investigations
In situ soil sampling
Groundwater / surface water sampling.
Scheduling laboratory testing

Tier 1 & Tier 2 Human Health Risk Assessment Reports.
Controlled water Risk Assessment
Preparation of factual and interpretive reports
Liaison with Environment Agency and Local Authority Contaminated Land Officers

Following a contamination investigation ACS will be able to provide you with details of remedial requirements that may be needed for the site. Our experienced Geo-Environmental Engineers will be able to produce a Remediation Method Statement for your site to outline what is necessary. Following this, we also are capable of producing a Validation Report. Validation Reports are typically the final step in a contaminated land investigation and will prepared to discharge a contaminated land planning condition.

Geotechnical Investigations

As well as contamination investigations, ACS also offer an extensive range of investigation techniques to provide the required geotechnical parameters for any development. The selection of investigatory method will often depend on site access, local geology and can often be carried out in buildings and factories and limited headroom situations.
