Wright-Patterson has lifted a months-long drinking water advisory imposed for pregnant women and infants because of groundwater contamination concerns, according to base officials.
Water sample tests showed levels of two compounds found in a firefighting foam were below the lifetime exposure threshold of 70 parts per trillion set by the U.S. Environmental Protection Agency, according to Wright-Patterson spokeswoman Marie Vanover.
The advisory was lifted Thursday, Vanover said Friday. Base officials said sampling has consistently showed drinking water is safe to drink.
Wright-Patterson also has stopped distribution of bottled water to the at-risk population, which started after the Ohio EPA ordered two drinking water wells closed in May because of contamination concerns.
The wells were shut down when the U.S. EPA lowered threshold standards for perfluorooctanesulfonic acid (PFOS) and perfluorooctanic acid (PFOA), two compounds found in aqueous film forming foam, also known as AFFF.
Those drinking water wells in Area A will remain closed, Vanover said.
The base had distributed more than 8,000 bottles of water to pregnant or lactating women and bottle-fed infants and patients at Wright-Patterson Air Force Base during the advisory.
