Abstract: Ground water from many municipal water wells in California has been degraded by tetrachloroethylene (PCE) at concentrations above the drinking water standard. Investigations conducted by the state have shown much of the PCE contamination was caused by wastewater discharges from dry cleaners to sanitary sewer systems. Local or state legislation is needed to halt such discharges to the sewer, and a statewide fund is needed to help small dry cleaning businesses pay for ground water cleanup.
