State and federal officials say they expect to make headway this year on an underground chemical plume expanding from a former Air Force base.
The chemicals (perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) are linked to firefighter training on the former Wurtsmith Air Force Base. The firefighters used the foaming chemicals to extinguish jet fuel fires starting in the 1960s. The base closed in the 1990s. But while Wurtsmith’s been closed for decades, the chemical plume continues spreading through the groundwater into local wells and nearby open water.
