1,1,1,2-Tetrachloroethane is a synthetic chemical used in manufacturing. It can enter water through industrial discharge and may cause liver and kidney damage.

1,1,1,2-Tetrachloroethane is a colorless, dense liquid with a sweet odor. It was historically used as a solvent and in the production of other chemicals. This compound can enter drinking water through industrial waste disposal or leaks from manufacturing sites. Environmental agencies typically measure its presence in parts per billion (ppb). While no longer widely used, it persists in the environment due to its slow degradation. Proper industrial waste management and water treatment are crucial for minimizing its occurrence in drinking water supplies.
