Biogeochemical Interactions Affecting Bioavailability for in Situ Remediation - Progress in Research, Superfund Research Program - May 13 and 20, 2019. This webinar series features individual research projects funded by the NIEHS Superfund Research Program (SRP). In 2013, the SRP initiated a targeted research program to better understand how contaminants in the environment are affected by complex biological, geological, and chemical processes. By understanding these complex interactions, we are better equipped to optimize remediation strategies and, therefore, improve science-based decision making for site management, priority-setting, and remedy selection. The individual research project grants support problem-solving research on the mechanisms of biogeochemical interactions that may impact remediation of contaminated soil, sediment, surface water, or groundwater.

Draft Interim Recommendations for Addressing Groundwater Contaminated with PFOA and PFOS. The EPA is seeking public comment on a draft set of recommendations for cleaning up groundwater contaminated with PFOA and PFOS. When finalized, the recommendations will provide a starting point for making site-specific cleanup decisions. The guidance is based on the EPA's current scientific understanding of per- and polyfluoroalkyl substances (PFAS) toxicity and is intended to provide clear and consistent guidance for federal cleanup programs. This information may also be useful for state and tribal cleanup programs, and in carrying out other federal regulatory authorities. Comments are welcome on any part of the guidance, including the use of EPA's Lifetime Drinking Water Health Advisory level of 70 ng/L or parts per trillion as the recommended PRG for groundwater, or whether higher or lower values would be supported.
