Use of RO membranes to remove PFOS, PFAS, GenX, and Dioxane from drinking water obtained from a surface water supply (Cape Fear River). Contaminants of concerns are present in water supply due to discharge of compounds to the river and current conventional treatment does not remove them. The wo-stage RO membrane pilot test demonstrated the ability of RO membranes to remove a high percentage of PFOS (>85%), PFOA (>80%), GenX (>90%), and 1,4 Dioxane (>90%) from the feed water to levels that were often below the analytical detection limits. RO also removed Acetaminophen; Atrazine; caffeine; DEET; Lidocaine; 2,4, D (herbicide); Ibuprofen; and other COC from the water.
