Stage 1 Preliminary Site Investigation (PSI)
Highmark Environmental Services conducts historical reviews of sites for liability assessments and real estate transactions, as part of Certificate of Restoration (CoR) Part 1 assessments, and as preliminary assessments on contaminated site investigations. A Stage 1 PSI typically includes files searches, reviews of historical documentation, a study of aerial photographs, personnel interviews, and site reconnaissance.
Stage 2 Preliminary Site Investigations (PSI)
and Detailed Site Investigations (DSI)
Since 1998, Highmark Environmental Services has conducted approximately 1200 Stage 2 PSIs (intrusive investigations). A Stage 2 PSI delineates contamination and determines the approach of independent remediation. A detailed site investigation builds on the findings from a preliminary site investigation, 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.
Independent Remediation
Highmark Environmental Services has remediated numerous sites using in situ treatment, risk management, bioremediation, natural attenuation, and excavation and hauling. Site investigations and remediation make up a large proportion of the work that Highmark Environmental Services performs.
Groundwater Well Installation & Monitoring
Highmark Environmental Services installs and monitors groundwater wells where groundwater impacts may have occurred or to determine whether drinking water criteria apply to a site. Highmark Environmental Services also performs rising head tests and collects groundwater samples from wells.
Electro Magnetic (EM) Surveys
Highmark Environmental Services conducts electromagnetic scans during contaminated site investigations using EM scans: EM31 (deep scan) and/or EM38 (shallow scan). An EM scan identifies the locations and intensity of conductive contamination, such as salts.
