PFAS presents many challenges. Among these are the thousands of potential contaminants, high solubility in water, common resistance to degradation and treatment by wastewater treatment plants, limited understanding of breakdown products, and toxicity at parts per trillion levels. Yet, much has been learned in how to manage, mitigate, and remediate contaminated sites that can be applied to PFAS. The panelists will discuss how we can apply lessons learned over the years with other contaminants to PFAS.

The lack of a federal standard regarding PFAS has created challenges at all levels of government. This presentation will address the most current legislative options being discussed, as well as some of the most interesting developments on the PFAS remediation side.

PFAS has quickly become the MTBE of this decade. Since the federal government has not currently established toxicity level and minimum standards, most states are struggling with this challenge in addition to ensuring safe potable water supplies and overseeing cleanup efforts in areas the contaminant has been discovered. Panel members from state, local, legal, and laboratory perspectives will share their experiences with the PFAS issue and paths forward to deal with these challenges.
