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. This allows for 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.

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