A commercial laboratory occupied this Property and solvents were disposed into an outside underground sump behind the building. The sump and contaminated soil were removed (LTCP # 2).
Trichloroethene (TCE) impacted groundwater spread down-gradient to adjacent parcels. ERAS installed monitoring wells to determine the extent of contamination (LTCP # 3 and 4). ERAS also collected sub-slab vapor samples inside an adjacent building that indicated no threat to indoor air. The RWQCB granted case closure under the LTCP.
