TREATMENT OF PERFLUORINATED ALKYL SUBSTANCES IN WASH WATER USING GRANULAR ACTIVATED CARBON AND MIXED-MEDIA

EPA 600-R-17-175, 44 pp, 2017

This report summarizes the results from testing conducted to evaluate the treatment of large volumes of water containing perfluorinated alkyl substances (PFASs), specifically treatment for water contaminated by aqueous film forming foam (AFFF) used in firefighting. The AFFF selected for this study was a product widely used historically, and it contained PFOA and PFOS. Treatment of the AFFF-contaminated water was investigated using Calgon Filtrasorb® 600 granular activated carbon (GAC) and Ziltek RemBind™ mixed media. The contaminated water was pumped through treatment media and then emptied into bladder tanks. The goal was to assess the respective performance of the two products to reduce the PFAS concentration before disposal of the water (e.g., in a sewer). https://nepis.epa.gov/Exe/ZyPURL.cgi?Dockey=P100U1IG.txt
