3.5` LANPAC® proven superior for removing PCE from groundwater in packed tower air strippers
Dry cleaning fluids have contaminated groundwater supplies in all areas of the United States. One of the most common contaminants is PCE (perchloroethylene or tetrachloroethylene, Cl2C=CCl2). As a suspected carcinogen, PCE must be removed from water to very low levels. The US EPA maximum contaminant level (MCL) for PCE in drinking water is 5 ppb (5 parts per billion, or 5 mg/L). States such as New Jersey have set MCLs as low as 1 ppb for PCE in public water supplies.
