When Eielson Air Force Base, located in the interior of Alaska, found high levels of perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) in their drinking water, they needed a solution that was effective, cost-efficient, and operable in extreme temperatures. Calgon Carbon’s Model 10 adsorption system, filled with FILTRASORB 400 granular activated carbon (GAC), was determined to be the best option.
Eielson AFB occupies more than 63,000 acres of land about 26 miles southeast of Fairbanks and about 110 miles south of the Arctic Circle. Eielson Proper has more than 10,000 assigned personnel. The base sources its drinking water from groundwater and uses pressurized greensand filters to remove high levels of iron and manganese.
