A multimillion-dollar federal study on toxic chemicals in drinking water across the country is facing delays because of a dispute within the Trump administration, according to several people involved in the study or who have knowledge of the process.
The dispute has implications for more than half a dozen communities where drinking water has been heavily contaminated with per- and polyfluoroalkyl substances (PFAS). Concerns about the chemicals have exploded nationally in recent years, following decades of PFAS use in products including non-stick cookware, water-resistant clothing, food packaging, carpets and military firefighting foams. Scientists say significant delays could limit the effectiveness of the study.
The unregulated chemicals are known to exist at some level in the drinking water of tens of millions of Americans, with one estimate placing the number as high as 110 million. The chemicals are also the subject of “Dark Waters,” a film released in November starring Mark Ruffalo and Anne Hathaway.
