Presentation Title

Case Studies for Selecting a PFAS Treatment Approach in Drinking Water

Anthony Hoffman, P.E., Southeast Area Manager and Lori Kappen, Senior Project Engineer, Gannett Fleming, Inc.

Abstract

Per- and poly-fluoroalkyl substances (PFAS) are emerging contaminants that have entered the public consciousness recently when low levels of these contaminants were discovered in numerous drinking water supplies across the US, and as sampling continues more drinking water supplies are added to the list. We will review and discuss three case studies that include water supply systems impacted with PFAS to explore multiple aspects that impact selection and design of a PFAS treatment system.  Issues that will be considered in this presentation include the types and concentrations of PFAS present and other source water quality parameters and contaminants, available space and other site constraints, ancillary facilities and equipment needed to support the treatment process, waste handling, competing or additive contaminants, system hydraulics, permitting, and capital and operating cost impacts.
