1,1-Dichloroethane is a synthetic chemical used in manufacturing and as a solvent. It can enter water from industrial discharge and may cause liver and kidney damage.

1,1-Dichloroethane is a volatile organic compound primarily used as an industrial solvent and in chemical manufacturing. It can contaminate drinking water through improper disposal or leaks from industrial sites. Environmental agencies typically measure its presence in water using gas chromatography. While it breaks down relatively quickly in air, it can persist longer in groundwater. Exposure to high levels may impact liver and kidney function, though more research is needed on its long-term effects at low concentrations found in some drinking water supplies.
