Remediation: The Journal of Environmental Cleanup Costs, Technologies, and Techniques is a quarterly journal that focuses on how to diagnose problems at hazardous waste disposal sites as well as how to select the best, most cost-effective technologies for cleanup. Each issue features articles by experts on issues including evaluating the costs of uncertainly in risk assessment, determining how clean is clean, using bioremediation successfully and cost-effectively, negotiating remediation contracts, treating hazardous wastes, and understanding regulatory issues.

Abstract

This paper summarizes key information on topics of contemporary interest in human and ecological per- and polyfluoroalkyl substance (PFAS) risk assessment, which were discussed at the PFAS Experts Symposium 2. For human health, the discussion focused on the toxicologic and epidemiologic endpoints and exposure assumptions that contribute to differences in PFAS regulatory criteria. For ecological risk, the discussion assessed the current state of the science available to support ecological screening levels and identified key data gaps and uncertainties in our understanding of ecological exposure and toxicity. Finally, the paper summarizes a panel discussion that addressed the challenges and uncertainties of regulating PFAS as a class.
