One summer day in 2017, a front-page story in the StarNews of Wilmington, North Carolina, shook up the lives of hundreds of thousands of people. The drinking water system, it said, was polluted with a contaminant commonly known as GenX, part of the family of “forever” PFAS chemicals.

It came from a Chemours plant in Fayetteville, near the winding Cape Fear River. Few knew about the contaminated water until the article described the discoveries of scientists from the Environmental Protection Agency and a state university. Given that certain types of PFAS have been linked to cancer, there was widespread anxiety over its potential danger.

In the onslaught of legal action and activism that followed, the EPA during President Donald Trump’s first term took an assertive stance, vowing to combat the spread of PFAS nationwide.

In its big-picture PFAS action plan from 2019, the agency said it would attack this complex problem on multiple fronts. It would, for example, consider limiting the presence of two of the best-known compounds — PFOA and PFOS — in drinking water. And, it said, it would find out more about the potential harm of GenX, which was virtually unregulated.

By the time Trump was sworn in for his second term, many of the plan’s suggestions had been put in place. After his first administration said PFOA and PFOS in drinking water should be regulated, standards were finalized under President Joe Biden. Four other types of PFAS, including GenX, were also tagged with limits.

But now, the second Trump administration is pulling back. The EPA said in May that it will delay enforcement on the drinking water limits for PFOA and PFOS until 2031, and it will rescind and reconsider the limits on the other four. Among those who challenged the standards in court is Chemours, which has argued that the EPA, under Biden, “used flawed science and didn’t follow proper rulemaking procedures” for GenX.

These EPA decisions under Trump are part of a slew of delays and course changes to PFAS policies that had been supported in his first term. Even though his earlier EPA pursued a measure that would help hold polluters accountable for cleaning up PFAS, the EPA of his second term has not yet committed to it. The agency also slowed down a process for finding out how industries have used the chemicals, a step prompted by a law signed by Trump in 2019.

At the same time, the EPA is hampering its ability to research pollutants — the kind of research that made it possible for its own scientists to investigate GenX. As the Trump administration seeks severe reductions in the EPA’s budget, the agency has terminated grants for PFAS studies and paralyzed its scientists with spending restrictions.

Pointing to earlier announcements on its approach to the chemicals, the EPA told ProPublica that it’s “committed to addressing PFAS in drinking water and ensuring that regulations issued under the Safe Drinking Water Act follow the law, follow the science, and can be implemented by water systems to strengthen public health protections.”

“If anything,” the agency added, “the Trump administration’s historic PFAS plan in 2019 laid the groundwork for the first steps to comprehensively address this contamination across media and we will continue to do so this term.”
