(Radio Iowa) – A new study finds military sites in Iowa and around the country have so-called “forever chemicals” known as PFAS in their groundwater which exceed new E-P-A health guidelines. The toxic compounds found in firefighting foam are linked to cancer and birth defects. The Environmental Working Group’s Jared Hayes says two-thirds of U-S military sites have PFAS contamination that violates standards that were set in June.

Hayes says, “This contamination doesn’t end at the base line and it has been shown to get into the communities across the U.S., into their drinking water and their wells of homes and nearby communities.” The EPA has lowered health advisory levels of two PFAS compounds from 70 parts per trillion to near zero. The Environmental Working Group report finds more than 260 military sites have groundwater levels of PFAS above the new threshold, including three military sites in Iowa. David Cwiertny, an environmental engineer at the University of Iowa, says the new health advisories are like when your car’s “check engine” light goes on. 

“When your car is flashing a red light at you, you don’t just keep driving,” Cwiertny says, “you figure out what’s wrong and ideally, if you have the resources, you invest it to fix it.” Among the three Iowa military sites with confirmed contamination, the Iowa Army Ammunition Plant in southeast Iowa has PFAS levels that would’ve been acceptable under the EPA’s previous health advisory, but now exceed new guidelines.

The author of the study says communities near military bases with unsafe PFAS levels should be given clean drinking water.
