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 $262,158 Project Grant award from the National Science Foundation's Division of Chemical, Bioengineering, Environmental, and Transport Systems (CBET) will fund research at the South Dakota School of Mines and Technology to develop advanced oxidation processes for controlling the formation of iodinated disinfection byproducts (I-DBPs) in drinking water treatment. The key objectives are to: 1) investigate the use of advanced oxidation processes like ferrate, ozone, and UV to optimize the...
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...
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...
This federal Project Grant award from the National Science Foundation's Engineering program (CFDA 47.041) provides $253,000 to the University of South Carolina to conduct a multi-part research study on a new class of disinfection by-products called halocyclopentadienes (HCPDs) found in drinking water. The key objectives are to: 1) assess the national occurrence of HCPDs in drinking water, 2) determine factors influencing HCPD formation, and 3) investigate the genotoxicity (potential cancer risk)...
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 $500,000 project grant awarded by the National Science Foundation's (NSF) Engineering program (CFDA 47.041) aims to engineer drinking water biofilms to achieve long-term biological stability and resistance to invasion, especially by pathogens. The project will use bench-scale experiments and a unique plumbing testing facility to control initial biofilm colonization, assess long-term biofilm stability, and explore models of biofilm-water interactions. The goal is to establish a competitive...
This $440,135 National Science Foundation Project Grant supports research at The Johns Hopkins University to develop a novel approach for identifying toxic byproducts and their precursors in drinking water treated with chemical oxidants. Funded under the NSF Engineering program (CFDA 47.041), the five-year award will support the principal investigator's research objectives to create a microbead-based reactivity-directed analysis assay for detecting organic electrophiles in water matrices and...
