Suspected source: Firefighting foam used at Fort McCoy
Three fire training burn pits are the sources of high PFOS concentrations in surrounding groundwater. Concentrations are as high as 120 µg/l – more than 1,700 times the EPA advisory level of 0.07 µg/l.
CSWAB formally petitioned the state to begin the rule-making process for PFOA and PFOS in September 2017. On March 2, 2018, Wisconsin DNR sent a letter to WDPH asking for state health-based groundwater standards for PFOA/PFOS.
