PFOS/PFOA Well Inventory

Hana as part of its JV (Hana-Bay West 8(a) JV) is assessing off-base PFAS impacts to drinking water at military installations across the US. Hana has completed comprehensive research including historical research, hydrogeologic evaluations, and well research within surrounding areas of the installations. Well research included evaluation of historical maps of the areas, coordination with local municipalities and state agencies, and utilizing online databases. All the well information was compiled into a database linked to GIS database for the ability of pulling up well information and locations on a map in real time. This allowed for the data to be manipulated for the identification of wells within a target area with the ability to export well information for that area. This project also includes Hana support to reach out to homeowners that have drinking water wells within the target areas. This includes mailings, phone correspondence, and in person visits. Once the property owner grants access the wells are sampled. Should the concentrations of PFAS in the well exceed the U.S. Environmental Protection Agency’s Lifetime Health Advisory Level, Hana will coordinate the delivery of bottled water until a more permanent option is available to mitigate the potential risk to residents from exposure to PFAS.
