Poly- and perfluoroalkyl substances (PFAS) in groundwater: An overview of chemistry, sources, fate/transport, and remediation.

Abstract:
Dr. Guelfo will present on how poly- and perfluoroalkyl substances (PFAS) have faced increased scrutiny by federal and state regulatory agencies, impacted populations, mainstream media, and social media. For example, the EPA recently issued lifetime health advisories for perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) in drinking water of 0.7 μg/L. Some states have opted to regulate PFOS, PFOA, and additional PFAS in drinking water at similar or lower levels, emphasizing a need for a complete understanding of sources, fate/transport, and toxicology as well as effective tools for groundwater remediation. PFAS are compounds with unique chemistry that can include surfactant properties, resistance to degradation, and both hydro- and lipophobicity. As a result they have been used in a variety of consumer and industrial products including non-stick cookware, food paper packaging products, stain repellant sprays, and firefighting foams. These same properties also lead to the extreme recalcitrance of some PFAS in the environment. This recalcitrance coupled with widespread use has led to global low-level PFAS distribution, with more elevated concentrations in groundwater measured near some sources such as manufacturing facilities and fire training areas. Once released, fate and transport will be governed by processes such as sorption and precursor transformation and may be influenced by the presence of contaminant mixtures. To date, studies of conventional in situ methods such as chemical oxidation have found these approaches incapable of full destruction of the wide range of PFAS found in subsurface environments, so ex situ techniques may be more appropriate for addressing immediate remediation requirements. Studies of PFAS at the lab, bench, and field scale provide insights into the current state of science and biggest challenges still faced in understanding fate, transport, and remediation of this unique class of compounds.

 

 

2016 Seminars

 

From Membrane Biofouling Control to Aquaporin Channels
Isabel Escobar, PhD, from the University of Kentucky
Wednesday, January 13, 2016
Download Presentation

Dr. Escobar recently joined the University of Kentucky’s Department of Chemical and Material Engineering. Previously she was a professor and associate Dean for Research Development and Outreach for the College of Engineering at the University of Toledo. Her main research emphasis is on sustainable water treatment.  She develops novel membrane technologies to treat a range of environmental contaminants. During the 2014 water crisis in Lake Erie (algal blooms and the impact on regional water supply), she worked closely with officials and made numerous media appearances addressing concerns over water safety.


 

Hope Lee, PhD, from the Pacific Northwest National Laboratory
Wednesday, February 17, 2016

Dr. Lee is formally trained in environmental microbiology and oceanography. Hope has specialized in the development and validation of microbial characterization and monitoring tools for use in environmental remediation for the past 12 years, and her work includes diverse clients including the US Air Force, Army, Navy, DOE, EPA, and private industry. She is an active member of ITRC and is currently serving as a technical lead for the Environmental Diagnostics Team.


 

Frank Loeffler, PhD, MS, from the University of Tennessee
Wednesday, April 20, 2016

Dr. Loeffler’s research centers on discovering microorganisms with novel properties to clean the environment, counter damage done to ecosystems by human activity, and improve environmental health. He examines how naturally occurring bacteria can eliminate or reduce the risk from pollutants including chlorinated solvents, radioactive wastes and greenhouse gases. His research also investigates new kinds of bacteria in an effort to develop innovative technologies for environmental monitoring and protection.

 


2015 Seminars

Update on the Sewer Gas to Indoor Air Pathway for Vapor Intrusion Sites

Kelly Pennell, PhD
Tuesday, December 1, 2015
Download Handout

Sewer lines and other infrastructure conduits can serve as “alternative” pathways for chemicals to be transported from hazardous waste sites to other locations. This presentation focused on sewers as one alternative pathway for transporting contaminated water and vapors long distances. Recently regulatory agencies have been placing increase emphasis on this pathway; and, it was specifically highlighted in the USEPA Finalized Vapor Intrusion Guidance, which was released in June 2015. The conceptual model for the sewer-gas-to-indoor-air-pathway was presented. Factors that are suspected to influence exposure risks were highlighted and ongoing numerical modeling efforts were discussed. Preliminary details of a GIS tool were also included in the presentation.  The GIS tool combines known sewer characteristics with hazardous waste site information and considers the potential for certain buildings to have a greater potential for this exposure pathway to exist.
