- This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant of $198,334 awarded to the University of Alabama will develop innovative models to enhance the ability to trace the origins of reactive pollutants in aquifers, a process known as backward tracking (BWT). The project will address limitations of traditional BWT methods that assume standard, or "Fickian," diffusion, by incorporating non-Fickian diffusion models to better represent the complex, nonlinear...
- This $499,988 Project Grant award from the National Science Foundation's (NSF) Engineering program (CFDA 47.041) seeks to develop and validate an integrated sorption-photocatalytic process for the ex-situ treatment and remediation of groundwater contaminated by mixtures of per- and polyfluoroalkyl substances (PFAS) and chlorinated solvents like trichloroethylene (TCE) and tetrachloroethylene (PCE). The principal investigator and research team at Southern Illinois University Carbondale will...
- 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 National Science Foundation (NSF) awarded a $499,942 Integrative Activities (CFDA 47.083) project grant to Central State University (CSU) to develop a novel computational framework for groundwater contamination forecasting. The project aims to create computationally efficient multiscale and statistical strategies for sampling subsurface properties to improve predictive models of water quality. The award will involve several CSU undergraduate students working with graduate students at the...
- This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award totaling $427,296 aims to advance the understanding of solute dispersion in unsaturated porous media, which has critical implications for processes like nutrient and contaminant transport in the vadose zone. The research project, awarded to the Trustees of the Stevens Institute of Technology, will leverage pore-scale numerical simulation, microfluidics, and 3D printing technologies to study how complex...
- This $235,137 project grant from the National Science Foundation (NSF) Office of Integrative Activities supports participation in a multi-country research initiative on sustainable conjunctive management of soil and groundwater resources. The award funds a U.S. research team contribution to a larger collaborative project selected through the Belmont Forum, a consortium representing over 55 countries focused on global environmental change challenges. The research will involve seven...
- This $180,267 federal Project Grant award from the National Science Foundation (NSF) Geosciences Program (CFDA 47.050) aims to investigate the impact of climate change on karst groundwater resources using advanced deep-learning techniques. The research, led by Sam Houston State University, will develop innovative deep-learning models to analyze comprehensive data from U.S. karst aquifers and integrate climate projection data to forecast the future status of these critical groundwater resources...
- The University of Florida was awarded a $999,721 Project Grant from the National Science Foundation's Geosciences Program (CFDA 47.050) to develop strategies to counter the effects of rising sea levels, climate change, urban sprawl, and farming on coastal groundwater supplies. The project will focus on the following key activities: Developing decision-support tools and recommending nature-based solutions to reduce groundwater hazards such as saltwater intrusion and flooding in low-lying, densely...
- This Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) provides $303,703 to develop a novel approach for characterizing hydrostratigraphy using water level data collected from multi-level monitoring wells. The University of Iowa will collect water level measurements every 10 seconds from 10 to 15 depths in monitoring wells located at a contaminated groundwater site. Analyzing the response of water levels to rainfall and pumping changes will help delineate the...
The National Science Foundation (NSF) awarded a $359,703 Project Grant under the Geosciences program (CFDA 47.050) to the University of Alabama for a research project titled "COLLABORATIVE RESEARCH: MODELING REACTIVE, DENSITY-DRIVEN GROUNDWATER FLOW TO IMPROVE CONTAMINANT REMEDIATION". This 3-year project, running from September 2025 to August 2028, will investigate novel methods for improving the efficiency and effectiveness of injecting chemical solutions underground to degrade groundwater contaminants. The research will leverage natural fluid movements induced by density variations to enhance mixing between treatment chemicals and pollutants in complex aquifer systems. The project will utilize laboratory experiments, mathematical modeling, and high-performance numerical simulations to study multi-species reactive transport in homogeneous and heterogeneous groundwater environments. In addition to advancing scientific understanding, the project will provide graduate and postdoctoral training, develop open-source groundwater modeling tools, and facilitate collaboration between academic researchers and an industry partner to transfer innovative remediation technologies into practice.
