1,1,1 Trichloroethane
Synthetic volatile organic compound originally developed as a less toxic substitute for other chlorinated industrial chemicals. It is currently used as a solvent and cleaning agent, and was previously an ingredient in household cleaning products, glues, and aerosol sprays. It is readily volatile, thus all routes of exposure (ingestion, inhalation and dermal) are relevant if one is exposed via drinking water. It has been detected in both surface water and groundwater.
