The objective of this presentation is to present a novel approach for classifying PFAS contamination under the National Classification System for Contaminated Sites in order to generate a more accurate representation of contaminant migration, potential for exposure to human and ecological receptors and priority for further action.

The objective of this presentation is to review surface water criteria for the protection of marine environments derived for PFAS in other jurisdictions, review publicly available data where migration of PFAS from upland sites to marine environments is occurring and outline a decision-framework for evaluating risks from upland sites to marine environments.
