EPA Publications about PFAS Research
U.S. EPA Science Inventory.

EPA's Science Inventory is a searchable database containing citations and abstracts of publications and presentations prepared by EPA staff.

Per- and Polyfluoroalkyl Substances (PFASs) in Your Environment
U.S. EPA website.

The home page links to information on PFOA, PFOS, and all other PFASs and PFCs.

Interest Groups

Association of State and Territorial Solid Waste Management Officials.

The purpose of this webpage is to provide the ASTSWMO membership with information on perfluoroalkyl and polyfluoroalkyl substances (PFASs), also known as perfluorinated chemicals, which are emerging contaminants of concern. The identification and cleanup of these contaminants may pose unique challenges in state cleanup programs.

Per- and Polyfluoroalkyl Substances and Your Health
Agency for Toxic Substances and Disease Registry (ATSDR).

ATSDR is involved at PFAS-related sites, either directly or through assisting state and federal partners. The Agency also has drafted fact sheets and a toxicological profile of perfluoroalkyl chemicals.

Perfluorinated Chemicals (PFCs)
National Institute of Environmental Health Sciences (NIEHS).

This webpage has links to general information on PFCs, what NIEHS is doing, and research in progress.


Advances in Perfluoroalkyl Chemicals (PFCs) Characterization and Remediation

Since FY11, SERDP and ESTCP have sponsored projects seeking to develop a better understanding of the occurrence, fate and transport, potential remedial treatment, and toxicological effects of potentially harmful polyfluoroalkyl substances (PFASs). SERDP and ESTCP post updates of the PFAS research projects they sponsor to this webpage with links to additional information.

Assistant Secretary of the Navy Energy, Installations, & Environment

Department of Navy policies, general information, and additional resources on perfluorinated compounds and perfluoroalkyl substances are provided.

C8 Science Panel
The Science Panel Website, 2013.

During 2005-2013, the C8 Science Panel carried out exposure and health studies in the Mid-Ohio Valley communities, which had been potentially affected by the releases of PFOA (or C8) emitted since the 1950s from the Washington Works plant in Parkersburg, West Virginia. They assessed the links between C8 exposure and a number of diseases. The C8 Science Panel has completed its work and no longer exists; this website summarizes the results.

Factsheets: PFOS and PFOA
The Expert Centre PFOS, Website sponsored by RWS Leefomgeving (the Netherlands) and OVAM (Flanders), 2016.

This site hosts a collection of factsheets about PFOS and PFOA. The factsheets are made by the Expert Centre PFOS, which aims to connect emerging contaminant issues with the fields of policy and legislation, science, stakeholders and problem owners, and business communities. Factsheets about PFOS and PFOA that are available in English include an introduction to the properties; production — use — sources; toxicology; behavior in soil and water; and an extensive bibliography.

U.S. Air Force Civil Engineering Center

The Air Force response to PFOS and PFOA, includes general information, infographics, and fact sheets.

The three presentations in this webinar include "DoD Chemical and Material Risk Management Program: Emerging Risks" (Yaroschak); "State of Knowledge on Per- and Polyfluoroalkyl Substances (PFASs) at Military Sites" (Field); and "Treatment of 1,4-Dioxane and Chlorinated Solvents Using Sustained Slow Release Chemical Oxidant Cylinders" (Evans).

Per- and Polyfluoroalkyl Substances (PFASs): Analytical and Characterization Frontiers
TerMaath, S., J. Field, and C. Higgins.
SERDP & ESTCP Webinar Series, 28 Jan 2016.

The three presentations in this webinar include "PFAS: An Air Force Perspective" (TerMaath); "Characterizing Fluorochemicals in AFFF-Contaminated Groundwater at Military Sites" (Field); and "Understanding the Transport of Perfluorochemicals in Groundwater at AFFF-Impacted Sites" (Higgins).

Perfluorinated Chemicals: Analytics, Occurrence, and Treatment
Shoemaker, J., M. Mills, and T. Speth.
Challenges and Treatment Solutions for Small Water Systems, 27 September 2016

With an emphasis on PFOA and PFOS, the first of three talks on perfluorinated compounds covers the approach, performance data, holding time studies, and contamination issues for EPA's analytical method. The second talk focuses on source water issues, including the impact of wastewater effluents. The third talk covers what is known from the literature regarding PFOA and PFOS treatment for the technologies commonly employed by drinking water facilities.

Bruton, Thomas.
CLU-IN Webinar, NIEHS Superfund Research Program (Sponsor), 20 June 2016.

This presentation provides an overview of research performed at UC Berkeley to develop chemical oxidation treatments for in situ PFAS remediation, which may prove to be a useful technique to manage PFAS plumes and protect municipal drinking water supply wells.
