Contaminated Sites Investigations for Northeastern British Columbia and Northern Alberta

Since 1998, Highmark Environmental Services Ltd. has conducted approximately 500 Stage 2 PSIs (intrusive investigations). A Stage 2 PSI delineates contamination and determines the approach of independent remediation. A detailed site investigation (DSI) builds on the findings from a preliminary site investigation (PSI), and is designed, often iteratively, to characterize the nature and extent of contamination identified through preliminary investigations. A detailed site investigation provides the information needed to satisfy regulatory requirements. More importantly, they provide the information that enables comprehensive evaluation of remediation options and quantification of liability.
