This is the second phase of ground investigation and follows a Phase I Desk Study. It allows up to date data to be gathered on ground conditions and the contaminative status of the soils and groundwater underlying the site. BWB use intrusive investigation techniques, in situ testing and laboratory analyses, the results of which are then used to qualify identified constraints or opportunities associated with the contaminative status of the site within the context of the project.
Once the Phase 1 and 2 investigations of a site have been completed, BWB offer an in-house capability to assess the risks posed to human health in line with the CLEA Framework, based on the determined contaminative status of the site. BWB have used the CLEA Framework to derive generic site assessment criteria (GSAC) values for a range of inorganic and organic contaminants in order to assess whether contaminant concentrations recorded on site pose unacceptable risks to human health receptors based on the proposed site end use.
