This Project Grant award, with a total funding amount of $620,000.00, was provided by the U.S. Geological Survey (USGS) under the Assistance to State Water Resources Research Institutes program (CFDA 15.805). The purpose of the project is to investigate how daily environmental fluctuations, or "diel cycling", impact the fate of per- and polyfluoroalkyl substance (PFAS) precursors in a unique, diatom-dominated constructed wetland. The interdisciplinary research approach combines field...

The researchers will monitor a suite of PFAS in an experimental...
The US Geological Survey, through its Assistance to State Water Resources Research Institutes federal grant program (CFDA 15.805), awarded Purdue University $487,497 for its project titled "PFAS Precursor Bioaccumulation and Biotransformation in Agriculturally Impacted Wetland Food Webs." The project will study the in vivo transformation and ecological effects of polyfluoroalkyl and perfluoroalkyl substance (PFAS) precursors in wetlands located in Indiana. Specifically, the researchers...
This $558,203 federal Project Grant awarded by the U.S. Geological Survey under the Assistance to State Water Resources Research Institutes program (CFDA 15.805) supports research at Purdue University to study the bioaccumulation and biotransformation of per- and polyfluoroalkyl substances (PFAS) in aquatic environments. Key project activities include: Integrating microfluidic sensors for rapid PFAS detection, field sampling of biofilms and macroinvertebrates, identifying factors influencing...
This $558,346 Project Grant awarded by the U.S. Geological Survey under the Assistance to State Water Resources Research Institutes program (CFDA 15.805) supports research at the University of Nebraska on the release, adsorption, and biotransformation of per- and polyfluoroalkyl substances (PFAS) at the water-sediment interface in agricultural watersheds. The key objectives are to: 1) measure the kinetics of PFAS release from decomposed biosolids and adsorption to sediments under anaerobic...
This $500,000 project grant from the US Geological Survey under the Assistance to State Water Resources Research Institutes federal grant program (CFDA 15.805) will fund a multi-year study at the University of New Hampshire investigating per- and polyfluoroalkyl substances (PFAS) in New Hampshire lake ecosystems. The study aims to determine concentrations and profiles of 40 PFAS compounds, including precursors and terminal compounds, in sediments, water, and benthic and pelagic organisms in...
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 Project Grant award from the U.S. Geological Survey (USGS) under the Assistance to State Water Resources Research Institutes program (CFDA 15.805) provides $558,345.00 to Purdue University to investigate the distribution, fate, and impacts of per- and polyfluoroalkyl substances (PFAS) in the Lake Michigan ecosystem. The project will assess PFAS accumulation in tissues of various fish species through lab experiments and field sampling, as well as measure biochemical and transcriptomic...
This Project Grant award of $622,873.00 from the U.S. Geological Survey's Water Resources Research Act (WRRA) Program (CFDA 15.805) will fund a research project at Purdue University to investigate the bioaccumulation and effects of per- and polyfluoroalkyl substances (PFAS) on largemouth bass reproduction. The project aims to characterize PFAS levels in ponds receiving biosolid runoff, determine if PFAS exposure impacts bass reproduction under field conditions, elucidate underlying molecular...
This $558,005 Project Grant award from the U.S. Geological Survey under the Assistance to State Water Resources Research Institutes program (CFDA 15.805) will fund a 3-year study on the occurrence, bioaccumulation, and biomagnification of per- and polyfluoroalkyl substances (PFAS) in natural and constructed wetlands.
The key objectives are to: 1) understand if PFAS concentrations increase through the wetland food chain and evaluate the ability of wetlands to remove these chemicals; 2) determine if wetland sediment is an internal source of PFAS and how this affects resident biota; and 3) assess the persistence and bioavailability of PFAS in wetland sediments. The research team will collect and analyze water, sediment, and biota samples from multiple wetland sites to generate data for these goals. The expected outcomes include a better understanding of environmental PFAS risks in wetlands and improved strategies for managing PFAS contamination. This work will inform policies and practices to protect human and ecological health in areas with PFAS-impacted wetlands.
