Trichloroethylene (TCE) in Drinking Water: Health Risks, Sources, and How to Remove It
Trichloroethylene (TCE) is an organic chemical contaminant regulated in public drinking water. The U.S. Environmental Protection Agency has set its Maximum Contaminant Level (MCL) at 5 μg/L to limit exposure. Monitoring for TCE helps ensure that public water systems remain within safe limits.
Health Effects
Exposure to Trichloroethylene (TCE) in drinking water can lead to health concerns. Consuming water contaminated with this chemical is associated with liver problems and an increased risk of cancer. Minimizing exposure is important for protecting long-term health.
How Trichloroethylene (TCE) Gets Into Tap Water
Trichloroethylene (TCE) is released into the environment primarily through industrial activities. Common sources of contamination include industrial discharge and runoff or infiltration from metal degreasing operations. These processes can allow the chemical to enter water supplies.
How to Remove Trichloroethylene (TCE) From Your Water
Effective treatment methods are available to reduce Trichloroethylene (TCE) levels in drinking water. Granular activated carbon and packed tower aeration are standard technologies used to treat and remove this contaminant. Utilizing these systems helps ensure water safety.
Should You Test Your Water?
You can check for the presence of Trichloroethylene (TCE) by reviewing your water utility's annual consumer confidence report or searching on WaterQ. If you use a private well in an area with industrial history, testing your water is a prudent step. You can also look up your local water system on WaterQ or check the Trichloroethylene (TCE) data page for reported levels in your area.
