EPA Releases Final Health Assessment for Trichloroethylene

3:34 PM MDT | September 28, 2011 | Kara Sissell

EPA has released its final health hazard assessment for trichloroethylene (TCE), characterizing it as “carcinogenic to humans and as a human noncancer health hazard.”  The assessment is part of EPA’s Integrated Risk Information System (IRIS) which conducts scientific reviews that underpin many of the agency’s regulatory decisions. The TCE assessment is also important to industry because it has the potential to influence a wide array of personal injury lawsuits and Superfund cleanup decisions. EPA’s release of the TCE assessment...

Comments (1) for EPA Releases Final Health Assessment for Trichloroethylene
I am happy to see the update and EPA News release of 'The Final Health Assessment for TCE'. It has been over forty years since Woburn, MA and I now have Grandchildren. Now I wish the the Obama administrations would get it right on greenhouse gas emission decisions on the environment.

As a scientist and former environmental consultant who was instrumental in the whistle blowing at Woburn, MA. and having personally worked on the Woburn site I take this as a positive step for all Americans. It is time for Americans to take our country back from the special interests and Corporations.

In the 1970s I was the scientist at Arthur D. Little, Inc Cambridge, Ma that caused the red flags to go up at the EPA over chemical contamination in Woburn, Massachusetts. Samples taken by me on an EPA contract that assessed salt and deicing practices and their ultimate disposition in the environment turned up the contamination. The sites I had selected for sampling were the Aberjona River and Horn Pond. Both sites were sampled by me weekly for many months. TCE (Trichloroethylene solvent) was not the intent of the study. I accidentally stumbled upon an array of chemical contaminates.

The EPA deicing study was conducted before cities and towns had to cover and store their road salts properly and led to the discovery of contaminated public drinking water wells with salt, gasoline, oil and other chemical contaminants. No one had ever looked for chemical contamination in that city prior to this study ground water contamination was an emerging field. At around the same time a student ( Fred DeFeo ) from Tuft's University was also investigating in Woburn. DeFeo wrote a research paper on contamination that he also found. Our lab results at ADL on the deicing contract went to EPA and sent up the red flags along with DeFeo providing additional research. Grace Chemical ended up being the fall guy for the Chlorinated solvents but was not totally responsible. There were many sources of contaminants over many decades all the way back to the old Beggs and Cobb tanneries.
