PCE Release Characterization and Remedial Action Design for a Dry Cleaners Site in Menlo Park

We completed a site characterization investigation that confirmed the presence of chlorinated volatile organic compounds (cVOCs), primarily tetrachloroethylene (PCE) in soil vapor above California Human Health Screening Levels (CHHSLs), in groundwater above drinking water Maximum Contaminant Levels (MCLs), and in soils at low concentrations. Subsequently, WHA devised a Remedial Action Plan and ran a pilot test for soil vapor extraction (SVE) at the property. The goal of SVE pilot testing was to determine via if this technology is feasible for the remediation of, and/or the mitigation of vapor intrusion by, chlorinated volatile organic compounds (cVOCs) or other COCs previously detected in vadose zone soil and soil vapor at the property.
