EPA Implements Ban on Toxic Chemical Trichloroethylene

The U.S. Environmental Protection Agency implemented a ban on the manufacture, importation, and processing of trichloroethylene (TCE) in March 2025. The rule had been delayed by a previous administration's regulatory review memorandum.

Health Risks of TCE Exposure

Trichloroethylene is a volatile organic compound previously used in industrial applications including dry cleaning, household cleaners, paint removers, and decaffeinated coffee.

Exposure to TCE has been associated with increased risks of Parkinson's disease, miscarriages, congenital heart defects, and cancers including kidney, liver, and non-Hodgkin lymphoma. Research from the University of Rochester Medical Center suggests TCE may contribute to Parkinson's disease, though exposure often occurs decades before symptoms appear.

The chemical can leach into the environment, potentially affecting people without occupational exposure.

Historical Background and Use

TCE was first synthesized in the 19th century as an industrial solvent. The chemical was used in various consumer products throughout the 20th century.

Contaminated water at Marine Corps Base Camp Lejeune led to litigation alleging TCE exposure contributed to Parkinson's disease and other health conditions in the surrounding community.

Ongoing Regulatory Actions

The EPA continues to conduct risk evaluations and propose regulations for toxic chemicals, particularly those that have been underreported in occupational settings.
