Presentation Title

PFAS Remediation - As Assessment of Current Practices – What Works and Where are We Headed?

Stephen Rosansky, P.E., Senior Research Scientist, Battelle


This presentation will describe recent applications and advances in technologies to address treatment of low concentrations of PFAS at point of use and higher concentrations in environmental restoration site source zones as well as treatment of investigation derive waste (IDW) and waste streams generated by primary treatment technologies such as granular activated carbon, ion exchange, and reverse osmosis and treatment of investigation derived waste.  Current research and application of novel and promising technologies to address this highly recalcitrant group of contaminants in the areas of adsorption, thermal, separation, and redox manipulation technologies will be presented.


Mr. Rosansky is a Senior Research Scientist in Battelle’s Environmental Solutions business.  He has a B.S. in Chemical Engineering from The Ohio State University.  He has more than 25 years of experience managing and conducting environmental restoration projects with emphasis on innovative technologies for cost-effective remediation of sediment, soil and groundwater.  He has substantial experience in applying and evaluating technologies such as in-situ bioremediation, in-situ chemical oxidation, multiphase extraction, air sparging and soil vapor extraction, six-phase soil heating, steam injection and bioventing to treat a wide range of contaminants of concern.  He has provided technical consulting support for the design and implementation of innovative remedies to treat media contaminated with metals, chlorinated solvents, and light non-aqueous phase liquids for the Department of Defense, EPA, and international clients located throughout the world.  Mr. Rosansky has contributed to the development of a number of guidance documents for the U.S. Navy pertaining to the application of innovative environmental technologies.  He is Battelle’s practice area lead for in situ remediation and currently serves as co-chair of the 12th International Symposium on Remediation of Chlorinated and Recalcitrant Compounds to be held May 31 through June 4, 2020 in Portland, Oregon.
