In this webinar we were pleased to have as a special guest speaker Jeff Hale, Practice Leader - Emerging Contaminants at Woodard and Curran. His presentation discussed attaining PFAS criteria in groundwater. He was joined by Dr. Kristen Thoreson, Vice President of Quality and Process Improvement at REGENESIS, who discussed the latest developments about colloidal activated carbon's use in the remediation industry as a low-cost method of eliminating PFAS risk.
Highlights of this free webinar:
-
Examination of the practicability of attaining PFAS criteria in groundwater and the distance from source at which these regulatory criteria are attained
-
Empirical fate & transport modeling using available data sources demonstrates expected distances to attainment of regulatory criteria
-
Use of colloidal activate carbon to eliminate risk of PFAS contamination in groundwater
Regulatory jurisdictions are establishing increasingly stringent, health-based criteria for per and polyfluoroalkyl substances (PFAS) in groundwater with the aim of protecting receptors at the point of exposure. The practicability of attaining these criteria in groundwater and the distance from source at which these regulatory criteria are attained without intervention have received little evaluation. Empirical fate & transport modeling using available data sources demonstrates expected distances to attainment, as well as the sensitivity of that attainment distance to various regulatory criteria and guidance values. The statistical distribution of these PFAS data sets also informs the approach and practicability of potential groundwater remedies.
