Case Studies for Selecting a PFAS Treatment Approach in Drinking Water
Aaron Getchell, CPG, P.G., Senior Geologist and Lori Kappen, Senior Project Engineer, Gannett Fleming, Inc.
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.
Mr. Getchell is an AIPG CPG and a PG in five southeastern states with more than 20 years of professional experience dealing with Brownfields redevelopment sites, contamination assessments, environmental due diligence, remedial action, and risk-based closure. Mr. Getchell earned a Bachelor’s degree in Geology from Eastern Kentucky University, completed a six-week geology field course through Bowling Green State University, and regularly participates in professional development for continuing education.
Ms. Kappen is a Senior Project Engineer with Gannett Fleming, Inc. and has 18 years of experience as a consultant, working with clients to assess water treatment facility performance, provide recommendations for improvement, and develop a basis of design concept.
