Conceptual Site Models and Phased Approaches in PFAS Investigations
Information regarding the presence or use of PFAS in certain products and industries is readily available. 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 recorded presentation explores unsuspected sources, providing a deeper dive into PFAS contribution from industries not directly affiliated with PFAS manufacturing or use. Case studies are 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.
