Hexachlorobenzene, a synthetic organic chemical, is a white crystalline solid. It does not occur naturally in the environment. Currently there are no commercial uses of hexachlorobenzene in the United States. It was used as a fungicide and to make fireworks and ammunition. Although it is not currently used commercially in the United States, hexachlorobenzene was widely used as a pesticide until 1965. It was also used in the production of rubber and wood preservatives. It breaks down very slowly and still persists in the environment. Small particles stick to soil and remain in sediments in the bottoms of water bodies; it accumulates in plants, grasses, fish, marine animals, birds and animals.
Some people who drink water containing hexachlorobenzene well in excess of the maximum contaminant level (MCL) for many years could experience liver or kidney problems; reproductive difficulties; increased risk of cancer.
MCL ADVISORY - ACTION IS HIGHLY RECOMMENDED
Hexachlorobenzene levels were detected in your water sample to exceed the maximum contaminant level (MCL).
ACTION IS OPTIONAL
Hexachlorobenzene levels were detected in your water sample but do not exceed the maximum contaminant level.
