This study aimed to develop passive samplers to detect PFAS in the field. Preliminary tests identified a suitable medium, which was then run through a series of adsorption experiments for 15 PFAS analytes. Equilibrium was achieved in <7 days for most of the analytes. Observed adsorption behavior varied significantly between the analytes, with longer chain compounds and sulfonates demonstrating higher sorption than shorter chains analytes and carboxylates. Sorption of PFAS onto the passive sampler was also affected by the water pH, ionic strength, and dissolved organic matter. The passive samplers will be field-tested on two Canadian sites with historical PFAS contamination in both groundwater and surface water. The presentation included a discussion of benefits, limitations, and future refinement needs of the technology and its applicability in site investigation and risk assessment. http://rpic-ibic.ca/images/2019_FCSRW/presentations/Passive_Sampling_of_PFAS-_Technology_Development_and_Applications_to_Site_and_Risk_Management_.pdf Longer abstract available by clicking on Stream 4a at http://rpic-ibic.ca/en/events/2019-federal-contaminated-sites-fcs-regional-workshops/2019-rpic-fcs-regional-workshop/2019-rpic-fcs-regional-workshop-oral-abstracts/2019-rpic-fcs-regional-workshop-stream-4a-innovation-research-and-development-pfas-assessment
