Sessions Description
Dynamic investigation approaches allow for flexibility during site characterization to manage decision uncertainty. The nature and extent of PFAS compounds are directly related to their release mechanisms (e.g., spraying of firefighting foam, aerial dispersion from an industrial facility, sewer discharges, or seepage from a landfill) that interact with the physical elements of the conceptual site model (CSM) (e.g., land use, topography, hydrology, stratigraphy, migration mechanisms, and transport pathways). Unique properties of PFAS further influence their fate and distribution. Consequently, insight and clarity are achieved by combining a robust three-dimensional CSM with knowledge of PFAS release and transport characteristics. The CSM …

Sessions Description
This presentation originates from a recent case study involving an accidental release of a sprinkler system in an airplane hangar, which discharged aqueous film-forming foam (AFFF) containing per- and polyfluoroalkyl substances (PFAS). The AFFF used was Ansulite 3%, a product among several other next generation AFFFs that came to market labelled as an environmentally friendly alternative to PFOS-based AFFF. It is understood that C6-based AFFF have consisted mostly of some variation with primarily 6:2 fluorotelomer betaine (6:2 FTAB), and secondarily 6:2 fluorotelomer sulfonate (6:2 FTS).In recent years these PFOS-alternative AFFF have also started being phased out by some agencies around …

Sessions Description
The FCSAP Expert Support Departments (ESDs) are working together to create an Interim FCSAP PFAS Guidance to be used to assess federal PFAS contaminated sites. An overview of what this document will contain will be shared. During this session, ESDs are interested in receiving feedback from custodians and/or consultants managing PFAS sites regarding their needs and current gaps. This feedback will be used to further develop the content of the guidance document in progress. A brief overview of environmental criteria will also be presented during this session followed by Q&As.

Sessions Description
This panel features four presentations by analytical laboratories followed by Q&As. The presentations will cover the entire process from sampling preparation to analytical data review including: best practices for PFAS sampling, how to select from multiple analytical methods for various environmental media including targeted and non-targeted analyses, as well as QA/QC and interpretation of laboratory data.
Speakers
Mary Ellen Starodub
National Risk Assessment Lead, AECOM Canada
Sessions Description
Key characteristics of PFAS when developing a problem formulation for risk assessment and the inherent uncertainties involved, under the current framework for risk management of contaminated sites in Canada, will be examined. Risk assessment of PFAS will be discussed in the context of Canada’s State of PFAS report and Risk Management Plan, and the available guidance and tools by Health Canada (including HC’s recent drinking water objective for PFAS as a class of contaminants), Environment and Climate Change Canada (ECCC), the Canadian Council of Ministers of the Environment (CCME), and other jurisdictions. A comparison will be presented of risk assessment …

Regulatory attention continues to grow around per- and polyfluoroalkyl substances (PFAS). Initially, much focus was on drinking water because that was recognized as the largest and most readily addressable human health exposure pathway. But, as research has expanded and more sites with drinking water issues are successfully addressed through treatment and remediation, …
