FRTR Fall 2024 General Meeting: Source Differentiation and Risk Assessments for Sites Impacted by PFAS
Sponsored by: Federal Remediation Technologies Roundtable
The FRTR 2024 Fall General Meeting provides an opportunity to share the latest developments in PFAS source differentiation and identification techniques applied to site remediation, as well as an update on advances in human health and ecological risk assessment. The meeting will highlight site-specific case studies where source differentiation technologies helped in identifying sites requiring further investigation and remediation. Emerging contaminants and issues have presented new challenges for risk assessment of both ecological and human health concerns. Therefore, meeting presentations will focus on new technical approaches to conduct site-specific risk assessments for PFAS when toxicological data, enforceable standards and similar information are limited.
