Why Has the E.P.A. Shifted on Toxic Chemicals? An Industry Insider Helps Call the Shots

 For years, the Environmental Protection Agency has struggled to prevent an ingredient once used in stain-resistant carpets and nonstick pans from contaminating drinking water.

The chemical, perfluorooctanoic acid, or PFOA, has been linked to kidney cancer, birth defects, immune system disorders and other serious health problems.

So scientists and administrators in the E.P.A.’s Office of Water were alarmed in late May when a top Trump administration appointee insisted upon the rewriting of a rule to make it harder to track the health consequences of the chemical, and therefore regulate it.

The revision was among more than a dozen demanded by the appointee, Nancy B. Beck, after she joined the E.P.A.’s toxic chemical unit in May as a top deputy. For the previous five years, she had been an executive at the American Chemistry Council, the chemical industry’s main trade association.

The changes directed by Dr. Beck may result in an “underestimation of the potential risks to human health and the environment” caused by PFOA and other so-called legacy chemicals no longer sold on the market, the Office of Water’s top official warned in a confidential internal memo .

The E.P.A.’s abrupt new direction on legacy chemicals is part of a broad initiative by the Trump administration to change the way the federal government evaluates health and environmental risks associated with hazardous chemicals, making it more aligned with the industry’s wishes.
