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.
