1,1,2-Trichloroethane is a synthetic solvent used in industry. It can contaminate groundwater through improper disposal. Exposure may damage liver and kidneys.

1,1,2-Trichloroethane is a colorless, sweet-smelling liquid primarily used as an industrial solvent and chemical intermediate. It can enter drinking water sources through improper disposal practices or leaks from industrial sites. This compound is measured in parts per billion (ppb) in water samples. While not as common as some other chlorinated solvents, its presence in groundwater is a concern due to its persistence in the environment. The EPA has set a maximum contaminant level goal of 3 ppb for this chemical in drinking water to protect public health.
