This five-year, $106,348 Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) will fund research to advance the understanding of thin-film-mediated retention and mass-transfer processes for surface-active contaminants in subsurface environments. The principal investigator and collaborators at the University of Arizona will combine thin-film theory, experimental characterization, and multiscale modeling to develop a cross-scale framework incorporating new...
This Project Grant award of $285,878 from the National Science Foundation's Geosciences Program (CFDA 47.050) will support research at the University of Wisconsin-Madison to investigate how fractures in underground rock formations impact the movement of water, solutes, and colloids through the subsurface. The key research objectives are to: 1) Quantify flow channelization and fracture-matrix exchange in fractured rock cores using advanced imaging; 2) Measure and model differences between...
The University of Arizona was awarded a $155,247 Project Grant from the National Science Foundation Division of Chemical, Bioengineering, Environmental, and Transport Systems under the Geosciences federal grant program (CFDA 47.050). The grant will support collaborative research to conduct in situ laboratory imaging and modeling of per- and polyfluoroalkyl substance (PFAS) transport and fate in variably saturated heterogeneous porous media from July 15, 2021 to June 30, 2024. The research aims...
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 University of Wisconsin-Madison received a three-year, $326,446 Project Grant from the National Science Foundation Division of Earth Sciences under the Geosciences program (CFDA 47.050). The grant will fund research from August 2021 through July 2024 to identify the role of dissolved organic matter composition in complete and partial photooxidation in diverse lakes. As part of the Geosciences program's goal to expand understanding of the integrated Earth system through basic research, this...
This Project Grant from the U.S. Geological Survey, under the Assistance to State Water Resources Research Institutes federal program (CFDA 15.805), provides $500,000 to the University of Wisconsin-Madison from December 2022 through December 2025. The funding supports research to quantify per- and polyfluoroalkyl substances (PFAS) bioaccumulation and potential health impacts in economically important plants and animals associated with aquatic ecosystems in ceded territories of the Great Lakes...
This three-year project grant from the National Science Foundation's Geosciences program (CFDA 47.050) provides $254,618 to the Colorado School of Mines to conduct research towards understanding the atmospheric fate of per- and poly-fluorinated alkyl substances (PFAS). The research team will quantify thermodynamic properties influencing PFAS phase partitioning, estimate atmospheric lifetimes against hydroxyl radical chemistry through multiple oxidation flow reactor experiments, and develop...
The University of Wisconsin-Madison received a two-year, $250,000 Project Grant from the National Science Foundation Division of Chemical, Bioengineering, Environmental, and Transport Systems under the Engineering (47.041) federal grant program. The grant funds research to develop inexpensive and rapid detection of per- and polyfluoroalkyl substances in drinking water supplies. The university will functionalize gold nanoparticles with macrocycles to detect these chemicals, which can be harmful...
This $963,000 Project Grant award from the National Institute of Standards and Technology (NIST) under the Congressionally-Identified Projects program (CFDA 11.617) will enable the University of Wisconsin-Madison (UW-Madison) to advance its PFAS Center of Excellence analytical capabilities. The grant will fund the acquisition of a liquid chromatograph high-resolution mass spectrometer (LC-HRMS) and an automated solid phase extractor (Auto-SPE) for the university's Core for Advanced Water...
