Eielson AFB chose bituminous re-agglomerated activated carbon to address PFAS contamination.
PFOA and PFOS are part of a group of organic fluorinated substances (PFAS) that have been used to make water-, stain-, and grease-resistant products. PFOA and PFOS are also present in the firefighting foam used at airfields for accidents and training.
With guidance from the EPA to remove PFAS from the water supply, the base began looking for the most effective, cost-efficient solutions. After considering different options — like coconut-based activated carbon and an ion exchange single-pass system — Eielson decided to pursue bituminous re-agglomerated activated carbon. After testing, it was determined that Calgon Carbon’s FILTRASORB 400 and Model 10 GAC adsorption systems were the ideal choice for contaminant-free drinking water.
An ambitious delivery schedule, extreme temperatures, limited daylight, and a constrained footprint made for a challenging installation. However, Calgon Carbon’s experienced field service team delivered and completed the project without issue.
After installing two GAC Model 10 systems and seeing great success, the base added two additional systems in 2017. Since then, all levels of PFAS have been undetectable. WW
