cis-1,2-Dichloroethylene is an odorless organic liquid that has two slightly different forms, a "cis" form and a "trans" form. Both the cis and trans forms — usually as a mixture — are used as a solvent for waxes and resins; in the extraction of rubber; as a refrigerant; in the manufacture of pharmaceuticals and artificial pearls; in the extraction of oils and fats from fish and meat; and in making other organics. The major source of cis-1,2-dichloroethylene in drinking water is discharge from industrial chemical factories.
Some people who drink water containing cis-1,2-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
cis-1,2-Dichloroethylene levels were detected in your water sample to exceed the maximum contaminant level (MCL).
ACTION IS OPTIONAL
cis-1,2-Dichloroethylene levels were detected in your water sample but do not exceed the maximum contaminant level.
