Status:ANNUAL WORKPLAN-ACTIVE SITE Lead agency:DEPT OF TOXIC SUBSTANCES CONTROL Background: The Lodi Central Plume Area (LCPA) site is located within the Lodi Area of Contamination (LAC) which occupies approximately 1542 acres centered on the intersection of School Street and Lodi Avenue in downtown Lodi, California. Contaminated groundwater was identified by the City of Lodi (City) in 1989,when they detected tetrachloroethene(PCE)and trichloroethene(TCE) at concentrations above the California Maximum Contaminant Levels (MCLS) in two of the City's municipal drinking water supply wells. The groundwater contamination is thought to have been due to on-site releases and wastewater discharges to the sanitary sewer from up to 43 locations throughout the City. DTSC's current Lodi Groundwater Project (Calsites ID 39990001) began in May of 1997 when DTSC executed the Comprehensive Joint Cooperative Agreement(Agreement)with the City for Investigation and abatement of the VOC contamination in Lodi. Through the Agreement,DTSC allowed the City to begin pursuing judicial action against PRP's to fully characterize and remediate the Site. DTSC issued the LCPA Imminent and Substantial Endangerment and Remedial Action Order(Docket No.I&SE 02/03-024)to PRPs on 5/30/03. DTSC took this action because the City of Lodi has not yet been successful in compelling the PRPs to investigate and remediate the Site,and because of DTSC's concern with significant threats of expanding groundwater contamination,additional impacts to supply wells,and the potential for VOC vapor intrusion from contaminated soil and groundwater to indoor air.
