As required by law, Dayton sent a formal letter to base and DoD officials in late March informing them of their intent to sue no later than May 4, unless they agreed to work with the city to mitigate the contamination problem. The Air Force previously declined the arrangement ― known as a tolling agreement ― that would have allowed continued cooperative work on the contamination problem while extending the time the city has to file a lawsuit under federal law, Dickstein said in April.
It’s disappointing that DoD twice declined the city’s offer for the tolling agreement, she said Monday.
Base officials in April disputed the city’s claims that PFAS from the installation is threatening Dayton’s drinking water supply. The groundwater near the base boundary is below the U.S. Environmental Protection Agency’s recommended action levels, the base said at the time.
The Air Force also conducts quarterly sentry well sampling to track any changing levels and regularly shares the information with the city, base officials said last month.
Dayton is seeking damages that range from $10 million to as much as $300 million, based on whether the DoD and Wright-Patt are willing to implement various treatment options to stop the alleged ongoing contamination, according to the lawsuit.
PFAS, dubbed “forever chemicals” for their longevity, can be found in firefighting foam, water-repellent fabrics, nonstick products, waxes, polishes and some food packaging, according to the U.S. EPA. Studies suggest that exposure to the chemical might affect pregnancy, increase cholesterol levels and cause some forms of cancer, according to the Centers for Disease Control and Prevention.
Babies born to mothers exposed to PFAS can be exposed during pregnancy and while breastfeeding. The chemicals can also decrease vaccine response in children, the CDC said.
Low levels of the contaminants were detected in 24 Southwest Ohio public water systems, including Areas A and B at Wright-Patt, according to the Ohio Environmental Protection Agency, which conducted a statewide study in 2020. All but one public water system in the region ― Aullwood Audubon Farm Discovery Center ― were below the federal recommended level of 70 parts per trillion.
