Putting PFAS Investigations into Practice Using Appropriate Conceptual Site Models
Fabio Fortes, Environmental Engineer and Nick Barnes, P.E., Environmental Engineer, HSW Engineering, Inc.
Per- and polyfluoroalkyl substances (PFAS) have been widely used in a variety of products by almost all types of industries. It is known that strong connections exist between PFAS sources and facilities such as airports, wastewater treatment plants, landfill facilities, and certain industries. How do we know if other facilities have a potential unknown source of PFAS or if the site has been impacted by external sources? A detailed investigation approach is recommended to understand the local hydrogeologic characteristics, as well as inventory studies of surrounding properties to identify and understand potential historical or offsite sources. This presentation will summarize these points of concern during an investigation of potential PFAS sources that may contribute to environmental impacts at a target site, and development of a Conceptual Site Model for characterizing the occurrence and fate of PFAS in the environment.
