Water Supply Well Surveys, Potential Perfluoroalkyl Substance (PFAS) Sites at BRAC Installations.
TREVET was contracted by the Navy perform surveys of public water supply wells within 3-mile perimeters around and within 137 Base Realignment and Closure (BRAC) sites at 37 installations in 17 states and three U.S. territories. This requirement is in response to a U.S. EPA health advisory (HA) for managing public drinking water systems where potential PFAS are present. The most common historic use of PFAS by the DoD was for firefighting at airfields. Well data was collected and filtered to identify those with indications as possible drinking water and other water supply wells. Research was conducted on hydrogeologic setting and groundwater flow direction information was used to identify the closest downgradient public supply wells. A report with BRAC site maps and plotted well locations, well data, and site-specific summaries was delivered 30 days following contract award. Data and findings will support DoD’s efforts to prioritize sites that may require additional site investigation activity or remedial response, as appropriate.
