Decision looming for Trump administration on first PFAS drinking water limits

In pain so bad he couldn’t stand, Chris Meek was rushed to the hospital with a life-threatening ruptured gallbladder. When he emerged from surgery, he learned he had kidney cancer that thankfully hadn’t yet spread.

Meek, a social studies teacher in Wilmington, North Carolina, was 47 at the time. But he remained confused for years about why, as someone seemingly not at risk, he had gotten cancer until Emily Donovan, a parent of students at his school, gave a guest talk about high levels of harmful forever chemicals known as PFAS in North Carolina’s environment. When Donovan mentioned kidney cancer, the possible cause of Meek’s diagnosis finally clicked.

Until then, Meek said, he “had no idea what PFAS was.”

Last year, the Environmental Protection Agency set the first federal drinking water limits for PFAS, or perfluoroalkyl and polyfluoroalkyl substances, finding they increased the risk of cardiovascular disease, certain cancers and babies being born with low birth weight.

In a decision with consequences for tens of millions of Americans, the Trump administration is expected to soon say whether it intends to stand by those strict standards and defend the limits against a water utility industry challenge in federal court.

In North Carolina, runoff from a Chemours plant contaminated the Cape Fear River, creating a crisis for cities like Wilmington that use it for drinking water. Amid public outcry, Wilmington effectively eliminated it from tap water.

Other U.S. communities — often near military bases or industrial sites — did the same when test results were frightening and public pressure, local leadership or state law forced PFAS-laden wells offline or prompted installation of expensive filtering systems, according to Mark White, drinking water global practice leader at the engineering firm CDM Smith.

The EPA said the PFAS found in North Carolina, often called GenX chemicals, can be toxic to the kidney. While other types of PFAS may raise kidney cancer risk, little research has focused on the link between kidney cancer and GenX, according to Sue Fenton, director of the Center for Human Health and the Environment at North Carolina State University. Chemours said evidence doesn’t support arguments that GenX at low levels is a health threat. The company has sharply reduced PFAS discharges.

So far, sampling has found nearly 12% of U.S. water utilities are above the recently set EPA limits, but most aren’t above by much. Forcing this group to reduce…
