Former Sewer Plant

FREY was retained by a real estate developer to provide environmental consulting and oversight of the demolition, assessment, and remediation of a former sewer plant. Regulatory oversight was provided by the Department of Toxic Substance Control (DTSC). The DTSC typically requires rigorous standards for sampling and analysis for environmental compliance. FREY collected and analyzed nearly 700 soil samples from the 60 acre site. FREY concluded that approximately 35 acres of mainly surficial soil was contaminated with polychlorinated biphenyls (PCBs) and dioxins. FREY estimated that nearly 200,000 tons of soil would need to be excavated and transported off-site for disposal to accommodate future residential home development.
