Webinar Overview: During this presentation, we will discuss a holistic overview of the evolving PFAS regulatory landscape and discuss how these shifts underscore the urgent need for the implementation of scalable, sustainable, and science-based solutions to cost-effectively manage PFAS in a manner protective of both human health and the environment.
PFAS has increased remediation liability by an estimated $120B to $175B. This is due to the low toxicity thresholds for PFAS including PFOS/PFOA at part per trillion concentrations for future residents. While most remediation sites are located at facilities that will remain under owner control for the foreseeable future and therefore may not require remediation to residential standards, the soil-to-groundwater pathway increases the potential for connected offsite receptors/users of groundwater. Therefore, the projected remediation costs are associated with these parts per trillion groundwater drinking standards. We will discuss potential risk management strategies to prioritize remediation through the use of mass discharge assessments.
Finally, anthropogenic sources of PFAS can create precipitation, soil, sediment, surface water and groundwater that also exceed health-based criteria. These “background” sources need to be considered as part of the remediation goals development as cleanup to be below background in not required under CERCLA and most, if not all, state cleanup programs.
We will also present case studies demonstrating successful PFAS source identification. These case studies will illustrate how high-resolution spatial data, forensic signatures, and targeted sampling approaches can inform strategic decision-making and reduce unnecessary treatment burdens.
