Carbon tetrachloride is a clear heavy organic liquid with a sweet aromatic odor similar to chloroform. Most carbon tetrachloride is used to make chlorofluorocarbon propellants and refrigerants, though this has been declining steadily. It has also been used as a dry cleaning agent and fire extinguisher; in making nylons; as a solvent for rubber cement, soaps, insecticides, etc. The major sources of carbon tetrochloride in drinking water are discharge from chemical plants and other industrial activities.
Some people who drink water containing carbon tetrachloride well in excess of the maximum contaminant level (MCL) for many years could experience problems with their liver and may have an increased risk of getting cancer.
MCL ADVISORY - ACTION IS HIGHLY RECOMMENDED
Carbon tetrachloride levels were detected in your water sample to exceed the maximum contaminant level (MCL).
ACTION IS OPTIONAL
Carbon tetrachloride levels were detected in your water sample but do not exceed the maximum contaminant level.
