Using Appropriate Conceptual Site Models and Phased Approaches in PFAS Investigations

Nicholas Barnes, P.E., Environmental Engineer, Verdantas

Information regarding the presence or use  of PFAS in certain products and industries is readily available and there are known to be strong connections between PFAS sources and facilities such as airports, wastewater treatment plants, landfill facilities, and certain manufacturing or other PFAS-using industries. How do we know if other facilities have a potential unknown source of PFAS or if a site has been impacted by external sources?  This presentation will explore unsuspected sources, providing a deeper dive into PFAS contribution from industries not directly affiliated with PFAS manufacturing or use. Case studies will be presented to provide a phased and detailed investigation approach to determine the specific conceptual site model for PFAS contamination at unsuspected sites and understand potential PFAS sources from historical or offsite sources.

Nicholas Barnes, P.E., is an Environmental Engineer at Verdantas. with over 15 years of experience in the assessment and remediation of environmental contamination. He has extensive experience in the evaluation and selection of remedial action cleanup strategies for a range of contaminants and has led PFAS characterization activities at numerous waste cleanup sites.
