FRTR Fall 2024 General Meeting: Source Differentiation and Risk Assessments for Sites Impacted by PFAS

The FRTR 2024 Fall General Meeting provides an opportunity to share the latest developments in PFAS source differentiation and identification techniques applied to site remediation, as well as an update on advances in human health and ecological risk assessment. The meeting will highlight sitespecific case studies where source differentiation technologies helped in identifying sites requiring further investigation and remediation. Emerging contaminants and issues have presented new challenges for risk assessment of both ecological and human health concerns. Therefore, meeting presentations will focus on new technical approaches to conduct site-specific risk assessments for PFAS when toxicological data, enforceable standards and similar information are limited.

Kent Glover, Ph.D., U.S. Air Force Civil Engineer Center (AFCEC) (kent.glover@us.af.mil)
Dr. Glover has been involved in groundwater and vadose zone remediation since the early 1980s. Currently, he is the Air Force Subject Matter Expert (SME) for Remediation Systems and provides technical leadership in remedy selection, implementation, performance evaluation and optimization. He also provides expertise in numerical modeling of contaminant fate and transport, and remediation of non-aqueous phase liquids. Before coming to the Air Force in 2010, he was a Principal Scientist for several engineering firms providing consulting services to private sector and governmental clients. From 1976 until 1989, he served in the U.S. Geological Survey as a hydrologist for groundwater contamination and water resources projects across the western United States. He holds a Ph.D. and M.S. in Environmental Science and Engineering from Colorado School of Mines and a B.S. in Watershed Science from Colorado State University.

Zachary Puchacz, Mead and Hunt
Zachary Puchacz has a combined 22 years of airport management and aviation consulting experience. His career began as an intern at the Kalamazoo/Battle Creek International Airport while earning a degree in Aviation Science and Administration from Western Michigan University. After graduating, Zachary became an airport operations coordinator at Teterboro Airport and later an airport operations officer at the Capital Region International Airport in Lansing, Michigan.

His experience with aqueous film forming foams (AFFF) as an airport firefighter while working in airport operations contributed to the research published in ACRP Research Report 173, Use and Potential Impacts of AFFF Containing PFASs at Airports, and ACRP Research Report 255, PFAS Source Differentiation Guide for Airports. Since the publication of these reports, Zachary has assisted airports nationwide in their strategies to address PFAS and transition to fluorine-free foams.

Linda Gaines, Ph.D., U.S. Environmental Protection Agency (Gaines.linda@Epa.gov)
Linda Gaines is an environmental engineer and environmental health scientist. Previously, she worked as a consultant performing environmental site assessments and water and wastewater work. She then worked for the Texas Commission on Environmental Quality writing Title IV and V air permits and later RCRA hazardous waste permits. After earning her Professional Engineer's license, she went back to school for her Ph.D. to focus on environmental health, and now works in the Superfund Science Policy Branch in the area of human health risk assessments. She maintains the Superfund Chemical Database Matrix (SCDM) and the Regional Screening Levels (RSLs). The majority of her time is spent as the Superfund subject matter expert for per- and polyfluoroalkyl substances (PFAS).

Paul Carroll, AFCEC (paul.carroll.1@us.af.mil)
