Adrienne Nemura, P.E. (MI, NC, OH) presented on the U.S. EPA's new Action Plan for Per- and Polyfluoroalkyl Substances (PFAS) for the U.S. Conference of Mayors' Water Council (MWC) in Columbus, Ohio on Friday March 29, 2019 with another update on October 25, 2019 in Napa, California.
Adrienne is a Principal Water Resources Engineer based in Ohio with nearly 35 years of experience focused on helping clients identify cost-effective and sustainable solutions to meet their water quality goals. She has worked for more than 40 cities and wastewater utilities and also state and federal regulatory agencies, industrial facilities, airports, attorneys, consulting firms, non-profit organizations, and trade associations.
The primary purpose of the Mayors Water Council (MWC) is to assist local governments in providing high quality water resources in a cost-effective manner. The MWC provides a forum for local governments to share information on water technology, management methods, operational experience, and financing of infrastructure development. The MWC monitors and responds, as appropriate, to federal legislative, regulatory or policy proposals affecting the delivery of municipal water services. The MWC also provides a forum to assist local government in exploring competition and public-private partnership approaches, and alternative methods of financing water infrastructure development.
Presentation DescriptionAdrienne Nemura, a scientific consultant with Geosyntec, gave a comprehensive description of EPA's new Action Plan on PFAS. Adrienne summarized that the class of chemicals at issue have wide reaching availability in manufactured products, anywhere from Teflon coating to fire suppression foam. She stated that numerous cases of public health impacts have been attributed to the variety of products with the PFAS/PFOA chemical constituents. EPA has moved the industry to voluntary removal of the class of compounds in U.S. manufacturing and products, but many imported products contain the same substances. In the meantime, the water quality standards being set for these chemicals are very conservative while EPA conducts the appropriate health studies. For example, one drinking water health advisory level, which is being used as a surface water quality standard, was set at a level equivalent to a consumer drinking 1,400 L [6,000 cups] of water per day from a contaminated tap for their entire life. Additionally, compared to known toxics such as chlordane, dioxin, etc., the newer forms of PFAS have shorter half-lives in the human body. One problem though, these chemicals are routinely found in human blood and tissue when tested.
