Evaluation of Existing Treatment Facilities for Processing Wastewater Impacted by PFAS
|
| Description: | 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.

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