The Trouble with TCE

Trichloroethylene, or TCE, was a chemical used by tens of thousands of businesses in the United States. It was an affordable tool for many. Yet, TCE had been associated with important health risks, including cancer and autoimmune disease. TCE potentially posed other risks as well: some researchers argued that low doses of TCE caused deformities in fetal hearts, while others argued that there was not enough science to back up this claim.

Over twenty years, a vigorous debate encompassing academic, government and industry voices played out around just how toxic TCE was. The American chemical industry and TCE end-users used lobbying to advocate for their positions. A loose coalition of activists, academics and journalists promoted their own, different, perspectives on TCE. Developments in the TCE story were often communicated to the public through investigative reporting, a field of journalism facing economic crisis.

The U.S. government and its Environmental Protection Agency were responsible for assessing TCE’s toxicity, leading to secondary policy decisions around how the chemical should be regulated. Yet, by the end of 2020, controversy remained around whether successive governments had been untowardly influenced by special interests in their TCE decision-making. Which stance should the Biden administration take in regards to TCE? More broadly, which broader lessons could be drawn from the TCE case? In particular, should the influence of lobbying on regulations and policies be constrained in any way?
