Trichloroethylene
Solvent that is used primarily for metal degreasing applications, as an intermediate for the manufacture of other chemicals, as an industrial solvent, and in dry cleaning and textile operations. TCE is the most commonly reported organic contaminant in drinking water and is readily volatile, thus all routes of exposure (ingestion, inhalation and dermal) are relevant if one is exposed via drinking water. The EPA has deemed trichloroethylene as 'likely to be carcinogenic to humans' by all routes of exposure based on the association between TCE exposure and kidney cancer. At low concentrations, TCE can adversely impact the immune system and development outcomes.
Health Guideline Level (HGL)
0 ppb
Maximum level that poses minimal health risk based on the latest science
Health Effects
Health protective levels for trichloroethylene in drinking water have been set by the EPA based on TCE's carcinogenicity (specifically kidney cancer). Both human and animal studies show that the immune system and fetal development are sensitive endpoints with respect to TCE exposure. Acute exposures unlikely encountered in drinking water can result in effects to the central nervous system, kidney, liver, and male reproductive system.
Affected Organs & Systems:
Common Sources
- Main source of trichloroethylene in source waters is contamination by industrial waste streams
- May also be present in groundwater as a breakdown product of the compound tetrachloroethylene
How to Remove It
Water filters certified under the following NSF standards are effective at removing Trichloroethylene:
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
Trichloroethylene is classified as a VOCs contaminant.
This contaminant primarily affects the developmental, immune-system, and other systems.
