The Department of Defense, specifically the Department of the Air Force, is conducting market research to identify qualified testing laboratories capable of analyzing PFAS levels in water at Shaw Air Force Base in South Carolina. The objective is to perform quarterly testing of unfinished water withdrawn from three sample ports of a newly installed water filtration system, utilizing Purofine PFA694E, to monitor the rate of exhaustion of the filtration media. This testing is crucial for ensuring the effectiveness of the water purification system and maintaining compliance with environmental standards.
