Evaluation of Existing Treatment Facilities for Processing Wastewater Impacted by PFAS


Research conducted as part of ACRP 173: “Use and Potential Impacts of AFFF Containing PFASs at Airports” (2017), revealed that some airports use existing glycol-water and/or fuel-water separation systems for pretreatment of wastewater impacted by Per- and polyfluoroalkyl substances (PFASs), prior to sending discharged foam solutions to a wastewater treatment facility. The efficacy of these systems in removing aqueous film forming foams (AFFFs) has not been studied, and it is not known whether changes to these systems could results in adequate AFFF removal. Further research is also recommended to evaluate volume criteria for disposal in local water treatment facilities. Most local municipal or airport-specific water treatment plants may not be effective in processing large volumes of runoff impacted by PFASs following training, testing activities, or emergency response. The research will help airports assess the effectiveness and viability of disposing of waste-impacted by PFASs (i.e., discharged AFFF/water mixtures) using existing facilities.


The objective is to develop a guidebook for how airports can use existing treatment facilities to adequately remove AFFF from wastewater.
