PFAS, or per- and polyfluoroalkyl substances, refer to a class of synthetic organic chemicals that are of environmental and human health concern in soil and water at exceedingly low, parts per trillion concentrations, are bioaccumulative, and can persist for decades in the environment. They have been widely used in many products, processes and sectors of the economy - their presence has been well documented at airports, military bases, manufacturing plants and solid waste facilities, among others. The types of PFAS used and found in the environment can vary considerably among these different sectors, and the release mechanisms can also vary widely. Consequently, their fate and transport through the subsurface can be challenging to decipher. Site management and remediation options must be tailored to address the specific chemical conditions presented by the PFAS type within the hydrogeologic and geochemical environment.

In this three-part series, you will learn about the similarities and differences among PFAS sources and environmental impacts in the infrastructure, manufacturing and waste sectors of our economy. Through case studies, you will see how site-specific characteristics and PFAS analytical data interpretation can be used to successfully characterize and differentiate PFAS sources and plumes. You will gain insights on site management and remediation decision-making in response to the type and extent of PFAS impacts, the presence of co-contaminants, and complex environmental matrices.

This three-part webinar series on PFAS will cover the following areas:

* Critical considerations and insights about PFAS investigations

* International regulations and the Canadian federal contaminated sites perspective

* PFAS uses and sources in the infrastructure, manufacturing and waste sectors

* Source and plume characterization and differentiation

* Case Studies - Effective site characterization strategies and best practice

Organized around 3 one-hour sessions:
