Trichloroethylene (TCE) in Drinking Water
EPA limits, health effects, and what to do if your water is affected.
🩨 Health Effects
TCE is a likely human carcinogen associated with kidney cancer, liver cancer, and non-Hodgkin lymphoma. It can also cause liver, kidney, and nervous system damage. TCE is one of the most common groundwater contaminants at Superfund sites.
📍 Sources in Water
TCE was widely used as a metal degreaser in manufacturing and by the military. Commonly found at former military bases, manufacturing facilities, and dry cleaning sites. It readily leaches from contaminated soil into groundwater.
✅ What To Do
Activated carbon filters and air stripping effectively remove TCE. Reverse osmosis also works. Homes near contaminated industrial sites or military bases may be at heightened risk. Contact your utility if you suspect TCE contamination.
Check your tap water for Trichloroethylene (TCE)
Search your ZIP code to see if your water system has had Trichloroethylene (TCE) violations, plus lead testing results and an overall safety grade.
Search your ZIP code →Data from the EPA's Safe Drinking Water Information System (SDWIS). MCLs reflect minimum federal standards; some contaminants may pose health risks below these thresholds.
