| Abstract | The purpose of this document is to establish the basis for a PHG for DCM in drinking water. DCM is a synthetic volatile chemical without known natural sources. The production of DCM exceeds 200 million pounds annually in the United States (U.S.) and it is used in more than ten industries. In 1993, the U.S. EPA characterized DCM as the third most commonly used halogenated solvent based on 1991 data. DCM is used principally as a solvent in the removal of paint and grease; as a propellant for aerosolizing paints, automotive products, and insect sprays; and as a process solvent in the manufacture of foam polymers, pharmaceuticals and photographic film coatings. Other major uses are as a cleaner in electronic manufacturing, a degreening agent for citrus fruits, and a blowing agent in the production of urethane foam. Sources of DCM contamination in drinking water are mainly discharges from pharmaceutical and chemical factories. DCM has been detected in finished and raw water supplies in the U.S., and in groundwater wells used as drinking water sources in California at median concentrations ranging from 0.7 to 10 mg/L ppb). |
