Environmental contractors sample the groundwater from former fire training area #2 at former Wurtsmith Air Force Base, Michigan, several times a month to monitor PFOS/PFOA levels after groundwater passes through various treatment systems. The Air Force installed a Granular Activated Carbon pump and treat system to cut off contaminant discharges from the FTA into Clark’s Marsh in April 2015. Water pumped through the GAC system is sampled once a month. Once a week, the Air Force pulls samples from three remediation systems that are part of a pilot study collecting data to evaluate system performance. These samples are sent to the University of Georgia and Oregon State University where chemical analysis are conducted. (Photo by Breanne Humphreys/ Air Force Photo Released)
