This $1,600,000 Project Grant award from the U.S. Environmental Protection Agency's Science to Achieve Results (STAR) Research Program (CFDA 66.509) aims to test engineering controls that could allow continued and beneficial use of biosolids on agricultural soil while sustaining PFAS-free agricultural products. The key activities include: (1) modeling PFAS solid-water coefficients and soil properties with/without powdered activated carbon, (2) developing machine learning models for PFAS...
This $1,598,849 Project Grant awarded by the U.S. Environmental Protection Agency's Science to Achieve Results (STAR) Research Program aims to understand per- and polyfluoroalkyl substances (PFAS) partitioning in wastewater treatment plant biosolids, accumulation in agricultural soils, and develop mitigation strategies. Key activities include: 1) sampling WWTPs nationwide to study PFAS loading and biosolid characteristics, 2) leveraging existing data to identify critical parameters for PFAS...
The National Science Foundation awarded a $119,998 Project Grant to the University of Arizona under the Engineering federal grant program (CFDA 47.041) to develop new sorbents that can stabilize per- and polyfluoroalkyl substances (PFAS) in sewage sludge. Approximately 55% of the 7.2 million dry metric tons of sewage sludge (biosolids) produced annually in the U.S. is applied as soil amendments and fertilizers in agriculture and land restoration. However, the increasing detection of PFAS in...
This federal Project Grant award, funded by the USDA National Institute of Food and Agriculture under the Agriculture and Food Research Initiative (CFDA 10.310), supports research to develop tools for detecting and reducing per- and polyfluoroalkyl substances (PFAS) contamination in bivalve seafood. The $300,000 award to the University of Delaware aims to enhance understanding of PFAS accumulation in bivalves, investigate environmental factors influencing PFAS uptake and elimination, and explore...
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 $800,051 federal Project Grant award from the U.S. Environmental Protection Agency's Science to Achieve Results (STAR) Research Program (CFDA 66.509) will support Temple University's research examining baseline levels of per- and polyfluoroalkyl substances (PFAS) in urban farming and gardening resources, as well as the bioavailability of PFAS in edible crops. The key activities of this 3-year project include: (1) quantifying the impact of soil, nutrient amendments, and irrigation water on...
This Project Grant award from the U.S. Environmental Protection Agency's Science to Achieve Results (STAR) Research Program (CFDA 66.509) will provide $1,600,000 to Texas Tech University System to evaluate the bioavailability and transport of per- and polyfluoroalkyl substances (PFAS) in agricultural environments. The key research activities include: (1) characterizing PFAS partitioning in plant cultivation and comparing with soil type and treatment, (2) evaluating PFAS uptake in fish through...
This $1,600,000.00 federal Project Grant award, funded by the Environmental Protection Agency's (EPA) Science to Achieve Results (STAR) Research Program (CFDA 66.509), will support Michigan State University's research to evaluate the fate, transport, and bioaccumulation of per- and polyfluoroalkyl substances (PFAS) on a Midwest crop-livestock farm that uses biosolid land application. The project aims to quantify PFAS precursor accumulation and develop protocols to screen and map PFAS...
This Project Grant award, valued at $300,000.00, was provided by the United States Department of Agriculture's National Institute of Food and Agriculture under the Agriculture and Food Research Initiative (CFDA 10.310) program. The project aims to explore the use of zinc oxide nanoparticles as a novel approach to manage and mitigate the effects of per- and poly-fluoroalkyl substances (PFAS) on agricultural crops, specifically alfalfa. The research will systematically assess how these...
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)...
