Aug 6, 2025 · An evaluation of treatment options for emerging contaminants, specifically PFAS, as well as an operational evaluation of the existing treatment plant. Bench-scale testing of powdered activated carbon (PAC) products for PFAS removal will be conducted. This testing will provide insight on the effectiveness of PAC for PFAS treatment. In addition, rapid small scale column tests (RSSCT) will be performed on one or more granular activated carbon (GAC) / ion exchange (IX) / alternative media options. This will provide information on the preferred option for post-filtration PFAS treatment. · $287k
