Presentation Overview:

The NIEHS Superfund Research Program (SRP) presents the second session in the Risk e-Learning series SRP Water Innovation - An Integrated Approach to Sustainable Solutions. Session II - Technologies for Water Remediation will feature SRP-funded projects related to remediation of hazardous substances in water. The presentations will highlight potential tools for reducing water contaminants, such as polychlorinated biphenyls, trichloroethylene, and other difficult to treat contaminants. Tools include enhanced membranes and in situ chemical treatment systems. Presenters will also discuss technology transfer opportunities and challenges.

Dibakar Bhattacharyya, Ph.D., and Lindell Ormsbee, Ph.D., from the University of Kentucky SRP Center will discuss their work on nanostructured membranes for water remediation. Membranes provide flexible technologies, and are extensively used for applications ranging from organics and virus removal to desalination. The integration of metal/metal oxide particles in membrane pore domain allow catalytic detoxification (for ex, PCBs, TCE) of water through both reductive and oxidative pathways. The presentation includes both lab-scale results and membrane scale-up and other translational activities needed for water remediation.

Alexis Carpenter, Ph.D., Chief Scientist at Triad Growth Partners and former Duke University SRP Center trainee will discuss her work on advanced composites for in situ remediation of groundwater and surface water. She is developing a range of composite materials for remediation of contaminated water with focus on tunability, low-cost, ease of use, and environmentally friendly materials. Discussion will focus on controlled release polymer structures (CRPS) for in situ chemical oxidation of chlorinated compounds in groundwater. She will also discuss recent work on novel composites for chemical reduction, sorption of heavy metals, and the opportunities for utilizing cellulose nanomaterials in water treatment technologies.

Thomas Bruton, a trainee at the University of California, Berkeley SRP Center, will discuss chemical oxidation of poly- and perfluoroalkyl substances in groundwater. Poly- and perfluoroalkyl substances (PFAS) have received increasing attention due to the ongoing discovery of groundwater contamination stemming from industrial facilities and sites where aqueous film-forming foam (AFFF) was used for firefighting. This presentation will provide an overview of research we have performed at UC Berkeley to develop chemical oxidation treatments for in situ remediation of PFAS. In situ chemical oxidation may prove to be a useful technique to manage PFAS plumes and protect municipal drinking water supply wells.
