This National Science Foundation Project Grant of $312,596 awarded on October 1, 2022 will support research at San Diego State University to develop an innovative "trap and destroy" water treatment technology for per- and polyfluoroalkyl substances (PFAS). The university will work to optimize adsorptive photocatalysts that can selectively absorb PFAS from water and then destroy the compounds using ultraviolet or solar light. Key deliverables under the 24-month award include...
This Project Grant award from the National Science Foundation's (NSF) Engineering program (CFDA 47.041) provides $241,750 to the University of Missouri System to study the transformation mechanisms and products of per- and polyfluoroalkyl substances (PFAS) during drinking water disinfection processes. The research will investigate how PFAS, an emerging group of pollutants found in drinking water, react with common disinfectants like chlorine and ozone. By integrating experimental results with...
The National Science Foundation (NSF) awarded a $499,997 Project Grant under the Engineering program (CFDA 47.041) to the Regents of the University of Michigan to fund research aimed at advancing the use of persulfate and powdered activated carbon for in situ capture and destruction of per- and polyfluoroalkyl substances (PFAS) contaminating groundwater. The 3-year project will: 1) evaluate reaction kinetics for PFAS degradation using the persulfate/activated carbon treatment process, 2)...
The National Science Foundation has awarded a $275,000 Project Grant to Water Illumination Inc., a small minority-owned business, to develop a tunable deep ultraviolet (UV)-based technology for the destruction of per- and polyfluoroalkyl substances (PFAS) in drinking water. This grant, funded under the NSF Technology, Innovation, and Partnerships (CFDA 47.084) program, aims to create a cost-effective, chemical-free water treatment system capable of nearly complete PFAS elimination without...
This $600,000 Project Grant award, funded by the National Science Foundation's (NSF) Mathematical and Physical Sciences program (CFDA 47.049), supports research by the University of California, Riverside on the mechanisms of dechlorination and defluorination of per- and polyfluoroalkyl substances (PFAS), also known as "forever chemicals." The 3-year project aims to study the molecular transformation and mitigation strategies for these emerging environmental contaminants. The research...
This $221,627 Project Grant awarded by the National Science Foundation (NSF) Engineering program (CFDA 47.041) to the Regents of the University of Minnesota focuses on investigating the transformation mechanisms and products of per- and polyfluoroalkyl substances (PFAS) during conventional drinking water disinfection processes. The research aims to determine how PFAS and their precursors react with common disinfectants like chlorine, chloramine, bromine, and ozone, in order to inform the...
The National Science Foundation (NSF) Division of Chemical, Bioengineering, Environmental, and Transport Systems awarded a $301,130 project grant to The Research Foundation for the State University of New York (SUNY) to study the molecular and nanoscale structure and interactions of per- and polyfluoroalkyl substances (PFAS) in aqueous solutions, at interfaces, and with other surfactants. The research aims to develop fundamental knowledge that supports improved water quality and the design of...
This $499,988 Project Grant award from the National Science Foundation's (NSF) Engineering program (CFDA 47.041) seeks to develop and validate an integrated sorption-photocatalytic process for the ex-situ treatment and remediation of groundwater contaminated by mixtures of per- and polyfluoroalkyl substances (PFAS) and chlorinated solvents like trichloroethylene (TCE) and tetrachloroethylene (PCE). The principal investigator and research team at Southern Illinois University Carbondale will...
The National Science Foundation (NSF) awarded a $458,143 CAREER program grant to George Mason University to investigate the fate, transport, and reactivity of per- and polyfluoroalkyl substances (PFAS) in drinking water distribution systems (DWDS). The goal is to evaluate the abiotic and biotic transformations of PFAS in DWDS, including in storage facilities and through biofilms, to advance solutions for PFAS drinking water contamination. The project will integrate field studies with...
This National Science Foundation (NSF) project grant, awarded under the Engineering program (CFDA 47.041), aims to elucidate the performance and mechanisms of nanofiltration (NF) for removing (ultra)short-chain per- and polyfluoroalkyl substances (PFAS) from contaminated water. The $227,460 award, effective September 1, 2024, will support an integrated experimental and computational approach to investigate key challenges in using NF for PFAS remediation, including evaluating removal...
