After Years-Long Review, EPA Appears To Tighten TCE Risk Levels

摘要

After years of scientific review and debate, EPA's just-released draft study of the risks posed by the ubiquitous solvent trichloroethylene (TCE) appears to strengthen the non-cancer safety limits-while generally backing the cancer risk limits-that the agency first proposed in a controversial 2001 draft.rnOnce finalized, the risk assessment will likely form the basis for setting strict cleanup levels at scores of contaminated sites and drinking water aquifers across the country, and help to bring consistency to the different state approaches that have been developed as regulators awaited a final decision from EPA.
