The Air Force Civil Engineer Center began a second

The Air Force Civil Engineer Center began a second round of drinking water sampling at the former Wurtsmith Air Force Base, Michigan, Aug. 1, 2017. The Air Force is re-sampling 54 private drinking water wells and two municipal wells near the installation to determine if perfluorooctanoic and perfluorooctanesulfonic acids, or PFOS and PFOA, levels have changed since 2015. Conducting follow-on sampling during peak pumping season allows the Air Force to evaluate seasonal variations. Sampling will be complete by the end of the month and AFCEC will notify well owners of validated results. (U.S. Air Force photo by Breanne Humphreys).
