This $349,044 Project Grant award from the National Science Foundation's Engineering program (CFDA 47.041) supports collaborative research to compare the concentrations and toxicity contributions of different classes of disinfection byproducts (DBPs) formed during drinking water treatment. The key objectives are to: 1) Compare DBP formation and toxicity between chlorine/chloramine disinfection and granular activated carbon treatment followed by chlorination; 2) Assess how water source, age,...
This National Science Foundation (NSF) CFDA 47.041 Engineering program award to Villanova University provides $199,991 to advance the understanding of how bromine (Br) and iodine (I) variability in drinking water sources contribute to the formation of disinfection byproducts (DBPs). The project aims to: 1) develop geospatial and statistical methods to assess iodine inputs to drinking water sources, and 2) perform targeted source water sampling to assess the spatial and temporal variability of...
The National Science Foundation (NSF) awarded a $221,627 Project Grant under its Engineering program (CFDA 47.041) to the Regents of the University of Minnesota to conduct research on the transformation mechanisms and products of per- and polyfluoroalkyl substances (PFAS) during drinking water disinfection processes. The 3-year project, beginning August 1, 2024, will investigate how PFAS compounds react with common disinfectants like chlorine and ozone. This research aims to improve...
The National Science Foundation awarded a $280,000 Project Grant to the Texas A&M University System Health Science Center under the NSF Engineering (CFDA #47.041) program. The grant supports a 3-year collaborative research project to advance the fundamental understanding of using visible light to activate peroxydisulfate and generate sulfate radicals for the degradation and mineralization of organic micropollutants in water treatment and wastewater reclamation. The project aims to measure...
This National Science Foundation (NSF) Project Grant award under CFDA 47.041, Engineering, provides $241,750 to the University of Missouri System to research the transformation mechanisms and products of per- and polyfluoroalkyl substances (PFAS) during water disinfection processes. The 3-year project, running from August 2024 to July 2027, aims to determine how PFAS and their precursors react with common disinfectants like chlorine and ozone during drinking water treatment. The research...
This Project Grant from the National Science Foundation's Division of Chemical, Bioengineering, Environmental, and Transport Systems provides $150,000 to support the development of quantitative tools to assess the mechanisms and potential of UV-activated persulfate radicals for treating per- and polyfluoroalkyl substances (PFAS) in water. With a completion date of July 31, 2024, this award under the Engineering (47.041) federal grant program will fund research at the California State...
This Project Grant awarded by the National Science Foundation (NSF) Division of Chemical, Bioengineering, Environmental, and Transport Systems (CFDA 47.041 - Engineering) supports research at South Dakota State University to develop advanced oxidation processes (AOPs) for controlling iodinated disinfection byproducts (I-DBPs) in drinking water. The $209,472 award will fund a 3-year collaborative effort to investigate the use of oxidants like ferrate, ozone, and UV photolysis to efficiently convert iodine and iodinated compounds into iodate, a non-toxic form. The project aims to integrate these AOPs with conventional water treatment processes to minimize the formation of both I-DBPs and regulated disinfection byproducts. The research will also involve developing analytical methods to measure iodine species and I-DBPs. In addition, the project will provide education and training opportunities for graduate and undergraduate students, including mentoring female students and engaging international students.
