Tips for reporting on 'forever chemical' can make a tricky job easier

PFAS are present in 45% of U.S. tap water.

Given the enduring presence of "forever chemicals," or PFAS, in the nation's soil and water, journalists will be covering and uncovering them for years to come. Because reporting on PFAS can be tricky, Rachel Layne of Editor & Publisher interviewed a panel of experts and condensed tips to make reporting on the topic more doable.

Here are her experts: Kelly Smalling, a research chemist at the U.S. Geological Survey; Linda Birnbaum, the former director of the National Institute of Environmental Health Sciences and the National Toxicology Program; E.A. Crunden, a chemicals and waste reporter for Politico's E&E News who covers PFAS and its regulation closely; Barbara Moran, a climate and environment correspondent at WBUR in Boston who has reported extensively on PFAS; Rebecca Fuoco, the director of science communications at Green Science Policy Institute; and Jamie DeWitt, a professor of pharmacology and toxicology at East Carolina University who follows PFAS closely.

Start with the basics. Journalists also should know and note why PFAS are nicknamed "forever chemicals." Manmade PFAS compounds don't degrade under typical conditions in the environment or the body. . . In recent decades, certain kinds of PFAS chemicals have been linked to serious health issues, including potentially higher risk for some cancers, autoimmune diseases, thyroid issues, liver disease, fetal complications, vaccine resistance and high cholesterol, among other concerns."

Note PFAS regulation on a national and local level. In March, the Environmental Protection Agency took a major step by proposing limits on six kinds of PFAS in drinking water under the national Safe Water Drinking Act. If enacted, the rule would cover the first new contaminant be the first new national standards under the act since the 1990s.

Study up, learn the terminology and how to use it. "Reporters should not buy into saying 12,000+ chemicals 'cause cancer'; that simply has not been proven yet, and research is limited," Crunden explains. "But good PFAS journalism should see you comfortably empowered to say at least two chemicals are strongly linked to cancer, and that there are concerns about the broader family, which also pose a number of other health issues." Note that toxins are the correct term for naturally occurring poisonous substances, Crunden explained. PFAS are manmade, which makes them toxicants, not toxins. "Toxic chemicals" would also be an accurate way to describe PFAS.

Keep your accuracy radar on high and double-check what sources say. You can find tips on how to characterize research findings accurately in this tip sheet from "The Journalist's Resource." Even scientists can make mistakes, especially those not steeped in PFAS research, says Jamie DeWitt.

Befriend a toxicologist. Find a public health, public works or university toxicologist familiar with PFAS and ask to sit down with them, DeWitt, Crunden and Moran recommend — especially one who specializes in drinking water.

Monitor academic research, keeping in mind that much of it never makes it into the news media. A good practice is to create alerts on services like PubMed and Eureka Alert! Many scientific studies are published behind a firewall. But journalists often can get access to scientific papers for free – if they know how to ask. This piece from The Journalist's Resource outlines how to set up free accounts with several top academic journal publishers.

Go to a public water board or local government meeting where PFAS is being discussed, or attend state hearings. As with any topic, some of the best story ideas come from meeting people you wouldn't normally encounter just working the phones or doing online research, Moran says. The National Conference of State Legislatures has state-by-state information on PFAS and drinking water. The map and key issue page from the advocacy group Environmental Working Group are also good places to start.
