1,1-Dichloroethylene is an organic liquid with a mild, sweet, chloroform-like odor. Virtually all 1,1-dichloroethylene is used in making adhesives, synthetic fibers, refrigerants, food packaging and coating resins such as the saran types. The major source of 1,1-dichloroethylene in drinking water is discharge from industrial chemical factories.
Some people who drink water containing 1,1-dichloroethylene well in excess of the maximum contaminant level (MCL) for many years could experience problems with their liver.
MCL ADVISORY - ACTION IS HIGHLY RECOMMENDED
1,1-Dichloroethylene levels were detected in your water sample to exceed the maximum contaminant level (MCL).
ACTION IS OPTIONAL
1,1-Dichloroethylene levels were detected in your water sample but do not exceed the maximum contaminant level.
