TCE (trichloroethylene)
Toxins · Chlorinated solvent
High exposure concern
Bottom line
Read Off Label rates TCE (trichloroethylene) a HIGH exposure concern (8.0/10) based on strong evidence of high harm magnitude and high occupational/exposed exposure prevalence.
EPA December 2024 final rule banning most TCE uses under TSCA — major regulatory action.
This entry describes an exposure rather than an added intervention.
What the evidence says
EPA December 2024 final rule banning most TCE uses under TSCA — major regulatory action. Vapor intrusion (groundwater contamination entering homes through sub-slab) is an often-overlooked exposure route. Parkinson's association (Goldman 2023) has gained substantial evidence — Camp Lejeune cohort showed elevated PD risk. **Status corrected 2026-08-29 — the row said "banned Dec 2024" and skipped what happened next.** The 2024 TSCA risk-management rule was challenged immediately: the Fifth Circuit granted a temporary stay on 13 Jan 2025, petitions were consolidated and transferred to the Third Circuit, which kept the stay on 16 Jan 2025 — then **lifted it on 28 March 2025 for every part of the rule except the TSCA §6(g) exemption provisions**. The prohibition on the majority of industrial and commercial uses accordingly took effect **15 September 2025**. EPA issued an interim final rule in September 2025 extending compliance dates for critical-infrastructure and national-security uses (TCE as a processing aid in nuclear fuel manufacture, and certain processors discharging to wastewater), and postponed the §6(g) exemption requirements to February 2026. Net: the ban is real and in force, with narrow carve-outs — not the clean single-date ban the row implied.
Mechanism
Industrial degreasing solvent; widespread groundwater contaminant near industrial/military sites (Camp Lejeune); IARC Group 1; established Parkinson's risk signal
Reported exposure / mitigation context
EPA Superfund maps; drinking water testing near industrial sites; vapor intrusion mitigation in affected homes
