PFAS testing delayed due to coronavirus concerns

摘要

Collection and sampling of a class of highly toxic chemicals are on hold in certain areas because of the coronavirus pandemic. As state governors enact strict lockdowns and the Centers for Disease Control and Prevention stresses social distancing, some testing of per- and polyfluoroalkyl substances, or PFAS, is delayed until the spread of the virus is contained and it's safe to travel. PFAS are a class of about 7,000 chemicals that were once used for Teflon cookware and firefighting foam. Studies now link the chemicals to multiple health problems, including thyroid issues and some cancers. Ohio EPA suspended testing on March 16 because of COVID-19 but was able to collect 229 out of 245 samples from schools and day cares, said the agency's Deputy Director of Communication Heidi Griesmer. "This measure is being taken due to the closure of many businesses and buildings where getting access to samples will not be possible," Griesmer said. She said the samples were prioritized "because they serve sensitive populations of children." Griesmer said that Ohio EPA will review the results from samples taken before March 16. PFAS contamination has been found in the Ohio River, and the state hosts several military bases contaminated with PFAS-laden foam.
