Retained by the purchaser (large biotech company) to conduct appropriate environmental assessments of the buildings and property to identify recognized environmental conditions, and determine associated risks and corrective action costs. Research facility consisted of seven buildings, with six of the buildings having significant laboratory space. Entire facility occupied 80 acres, developed in the late 1960’s. Previous facility operations caused chemical releases to property soil and groundwater. Numerous environmental investigations and remediation activities were completed on property with oversight from the California Department of Toxic Substances Control (DTSC). Property included wetland areas, and potential for endangered or specially protected wildlife and habitats.

Initial environmental assessment activities included review of extensive existing environmental investigation and remediation documentation (including an asbestos survey), comprehensive review of facility construction and operational documentation, interviews of key facility staff, thorough facility inspection, and review of environmental agency records. Findings required conduction of environmental sampling in the buildings and a soil and groundwater investigation, including installation of groundwater monitoring wells. Building environmental sampling included wipe sampling and analyses of laboratory hood exhaust ducts and certain floor surfaces. Results of environmental assessment activities documented in two written reports, and factored into the purchase agreement with seller.
