Federal and local leaders said Monday they will work together on concerns tainted groundwater at Wright-Patterson could reach a city of Dayton well field.
U.S. Rep. Mike Turner, R-Dayton, said at a press conference Monday at Wright-Patterson existing or future legislation might help both the city of Dayton and the base as they deal with groundwater tainted from a firefighting foam contaminant.
Turner, Dayton Mayor Nan Whaley, Wright-Patterson installation commander Col. Bradley McDonald, Montgomery County Commissioner Deborah Lieberman and Dayton Development Coalition vice president Maurice McDonald had similar messages at the press conference at the Hope Hotel and Conference Center.
“I think it’s clear that we’re all on the same page,” Whaley said. “I think that that’s a very big deal.”
Wright-Patterson officials say they have reacted with urgency to concerns over tainted groundwater despite the city of Dayton’s demands asking for additional action to prevent the potential threat of groundwater contamination reaching the Huffman Dam well field.
But if upcoming expanded testing this summer determines a tainted groundwater plume is migrating off site, the Air Force will take additional actions, Wright-Patterson officials say. Groundwater on the base is believed to have been tainted by a contaminant in firefighting foam.
City, Ohio Environmental Protection Agency and Wright-Patterson officials say the drinking water is safe.
The city says monitoring wells at that Mad River location detected contamination of up to 1,260 parts per trillion of polyfluroalkyl substances (PFAS),which was found in an old formula of the firefighting foam. The U.S. EPA has set a health advisory threshold of 70 parts per trillion for lifetime exposure in drinking water.
For the first time, the city detected less than 10 parts per trillion of the contaminant last November at its Ottawa water treatment plant.
Dayton has asked for the support of neighboring communities to pressure Wright-Patterson to take action more quickly on concerns tied to the Huffman well field. The city also has asked the Air Force for nearly $1 million to defray the costs of environmental studies and testing related to Huffman well field concerns.
Among the demands Dayton has issued to Wright-Patterson: Install additional monitoring wells along the base boundary; relocate a Mad River storm water discharge point by about 200 feet so it won’t flow past a city intake; and sharing water data so the city can plan how to respond.
For more than two years, Wright-Patterson has addressed tainted groundwater concerns, base officials say.
Among the actions the base cited: Identifying where the firefighting foam was sprayed at training and crash sites on base; testing soil and groundwater for contamination and tracking possible pathways for tainted groundwater to migrate on and off base; temporarily shutting down two drinking water wells in 2016 that exceeded EPA advisory thresholds; and building a $2.7 million water treatment facility to resume pumping from those closed wells last June.
Wright-Patterson is replacing the old firefighting foam with a newer version officials have said is environmentally friendlier.
The Air Force investigation and mitigation efforts “are in full compliance” with state and federal laws, the base said in a statement.
“To ensure a comprehensive investigation into potential threats to community drinking water, the Air Force encouraged the city to investigate whether civilian fire training centers are impacting drinking water well fields and treatment plants,” the statement added.
Ohio EPA has ordered both Wright-Patterson and the city of Dayton to take action on the groundwater contamination.
PFAS contamination, at certain levels, can cause major health concerns. According to the U.S. EPA, human epidemiology and animal testing studies indicate high-level exposure to the contaminant may lead to testicular and liver cancer; changes in cholesterol; low birth weight in newborns; liver tissue damage; and effects on the immune system and thyroid.
The retardant that produces PFAS was sprayed at both Wright-Patterson and Dayton’s firefighting training center.
