1,1,1,2 Tetrachloroethane
Synthetic volatile organic compound (VOC). It was formerly used as an industrial solvent, and to produce pesticides, bleaches, and paints, but currently has no known uses besides as an intermediate in the production of other chemicals. 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 wastewater, drinking water, groundwater, and surface water near contaminated sites. It evaporates easily from surface water, so it is more likely to be detected in groundwater sources.
Health Guideline Level (HGL)
0.574 ppb
Maximum level that poses minimal health risk based on the latest science
Health Effects
Health protective benchmarks for 1,1,1,2-tetrachloroethane in drinking water are based on potential liver and kidney toxicity. The EPA classifies it as a possible human carcinogen.
Affected Organs & Systems:
Common Sources
- Not naturally occurring, so its detection in the environment and source water is the result of human activity
- May enter the environment and drinking water sources through release from industrial manufacturers that produce chemicals for which it is an intermediate
How to Remove It
Water filters certified under the following NSF standards are effective at removing 1,1,1,2 Tetrachloroethane:
Health Guideline Level
The HGL represents the maximum level that poses minimal health risk based on the latest scientific research. It's often more protective than federal legal limits.
Contaminant Type
