Dayton intends to sue WPAFB By London Bishop DAYTON — The city of Dayton has notified Wright Patterson Air Force Base and the Department of Defense of an intent to file a lawsuit, alleging the installation is contaminating the city’s water supply. In a formal letter , the city said it will file the lawsuit in the next 60 days, unless Wright-Patt and the DoD take action to address “per-and polyfluoroalkyl (PFAS) substances” leaching from the installation site. According to Dayton City Manager Shelley Dickstein, the lawsuit is a last resort. “As the leading acquisition and development center in the U.S. Air Force, WPAFB is a beacon in our community. The City absolutely does not want to file this lawsuit,” she said.
