Here's a direct link to the EPA's 2001 Document: Trichloroethylene Health Risk Assessment: Synthesis and Characterization (external review draft)

From the EPA's abstract:

This assessment presents EPA's most current evaluation of the potential health risks from exposure to trichloroethylene (TCE). TCE exposure is associated with several adverse health effects, including neurotoxicity, immunotoxicity, developmental toxicity, liver toxicity, kidney toxicity, endocrine effects, and several forms of cancer. Mechanistic research indicates that TCE-induced carcinogenesis is complex, involving multiple carcinogenic metabolites acting through multiple modes of action. Under EPA's proposed (1996, 1999) cancer guidelines, TCE can be characterized as "highly likely to produce cancer in humans."

Update:

I'm trying to find the published responses to this document. I know the Halogenated Solvents Industry (along with several others, if I recall correctly) filed a rather lengthy response. If anyone knows where I can find these, please email me.
