Description
The National Institute of Environmental Health Sciences (NIEHS) Superfund Research Program (SRP) produces a monthly Research Brief Podcast that highlights the research of SRP grantees. The SRP is a network of university grants that seek solutions to the complex health and environmental issues associated with the nation's hazardous waste sites. The research conducted by the SRP is a coordinated effort with the Environmental Protection Agency, which is the federal entity charged with cleaning up the worst hazardous waste sites in the country.

Nanoparticles Help Plants Clean Up “Forever Chemicals”
2025/10/22
Scientists funded by the NIEHS Superfund Research Program developed a novel material that enhances the ability of plants to remove PFAS from soil and water.
Dioxin-Like Compounds Shift the Balance of White Blood Cells
2025/08/27
Dioxin-like compounds can alter how white blood cells develop and do so in ways that current risk assessment methods fail to predict, according to a study from the Michigan State University Superfund Research Program Center.
Demonstrating a Pilot System to Electrochemically Remediate Groundwater
2025/06/11
Researchers partially funded by the NIEHS Superfund Research Program (SRP) designed a scaled-up electrochemical system that combines electricity with the mineral pyrite, a mineral commonly found in the environment, to continuously remove organic and heavy metal contaminants from groundwater for a year. The study was led by Akram Alshawabkeh, Ph.D., from the Northeastern University SRP Center, and Kitae Baek, Ph.D., from Jeonbuk National University in Korea.
Mechanism Linking Preconception Arsenic Exposure and Diabetes in Offspring Revealed
2025/05/14
Exposure to inorganic arsenic before conception can trigger changes in gene activity that are passed down to offspring and increase their risk of developing diabetes, according to a study in mice funded by an NIEHS individual research grant and by the NIEHS Superfund Research Program. These changes, known as epigenetic changes, alter how genes work without changing the genes themselves. In this study, the researchers looked at a type of change called CpG methylation.
Machine Learning Creates More Complete Picture of Groundwater Contamination
2025/04/02
Machine learning algorithms can fill gaps in sparse or incomplete groundwater datasets, according to researchers partially funded by the NIEHS Superfund Research Program. The study tested the ability of two algorithms to help scientists analyze co-occurring pollutants in groundwater by filling in missing field data points and was led by researchers from Arizona State University, Harvard University, and North Carolina State University.
Using a New Model to Identify Health-Impacting Metal Mixtures
2025/03/12
Researchers funded by the NIEHS Superfund Research Program, or SRP, developed the linear mixed-effects model – abbreviated as LMM – a framework for statistical analysis, to quickly and effectively estimate the effects of individual metals and metal mixtures on zebrafish larvae behaviors.
Machine Learning Predicts Efficiency of Micropollutant Removal
2025/02/19
Scientists at the NIEHS-funded North Carolina State University Superfund Research Program Center created machine learning models that can help predict how well granular activated carbon can clean up contaminated water. With his student Yoko Koyama, Detlef Knappe, Ph.D., developed models that consider properties of the micropollutants — such as PFAS and volatile organic compounds — specific characteristics of the water being treated, and features of different GAC types.
Model Predicts PFAS Buildup in Wild Animals
2025/01/08
Researchers funded by the NIEHS SRP developed a model that predicts how PFAS move and build up within food webs. The model lays the groundwork for screening the thousands of PFAS compounds that could potentially pose a risk for ecological or human health. PFAS are synthetic chemicals used in consumer products that are ubiquitous on the planet and in some cases harmful to humans and wildlife.
Combining Plants and Sunlight to Break Down Hazardous Compounds
2024/12/03
Researchers funded by the NIEHS Superfund Research Program designed a new material that effectively degrades harmful compounds, like PFAS, and bacteria. By combining the power of sunlight and a component of plants, called lignin, this approach harnesses sustainable and renewable resources to reduce exposures and protect health.
User-friendly Technology Detects NDMA in Water
2024/11/06
A new technology, developed by researchers at the NIEHS-funded Massachusetts Institute of Technology Superfund Research Program Center, can detect the contaminant N-nitrosodimethylamine (NDMA) in water. This breakthrough tool offers a quick way to monitor NDMA by triggering a visible color change when light interacts with the contaminated solution.
Passive Samplers Track PFAS, Show Contamination Reduction in Cape Fear River
2024/10/02
Common low-cost samplers may be an effective technology for tracking PFAS levels in aquatic environments, according to a study funded by the NIEHS Superfund Research Program (SRP). The research team found that frequently used passive sampling devices, which collect samples over time, can monitor how PFAS mitigation strategies affect PFAS levels along a stretch of the Cape Fear River in North Carolina. Erin Baker, Ph.D., a project leader at the Texas A&M SRP Center and part of the analytical core at the North Carolina State University SRP Center, led the team.
Early Life Exposures May Shape Infant Immune System
2024/09/04
Exposure to certain chemicals during early pregnancy may influence how a baby’s immune system develops, according to a study partly funded by the NIEHS Superfund Research Program (SRP). The scientists discovered that some per- and polyfluoroalkyl substances (PFAS) and metals may alter how an infant’s immune system responds to environmental triggers.
Pyrite Improves Electrochemical System for Removing a Chemical Mixture
2024/08/07
Adding a common mineral, pyrite, to an electrochemical system can simultaneously remove organic and heavy metal contaminants from groundwater, according to a study funded in part by the NIEHS Superfund Research Program (SRP). Led by Akram Alshawabkeh, Ph.D., researchers at the Northeastern University SRP Center found that combining two types of remediation techniques – one that relies on applying an electrical current to destroy contaminants and one that uses minerals to adsorb contaminants – removed pollutants more effectively than either strategy alone.
Environmental Factors Alter PFAS Removal by Specialized Nanomaterials
2024/07/10
Researchers funded by the NIEHS Superfund Research Program (SRP) revealed how characteristics of water treatment systems may alter the ability of novel nanomaterials to remove PFAS. Scientists should be aware of factors like water pH ' a measure of acidic or basic conditions ' or salt level to ensure that these nanomaterials effectively remove PFAS in aqueous environments, according to the team based at the State University of New York at Buffalo.
High Seafood Diet May Lead to Increased PFAS Exposure
2024/06/05
A study funded by the NIEHS Superfund Research Program (SRP) found that consuming some types of commercial seafood in high quantities may increase the risk of PFAS exposure. Led by Celia Chen, Ph.D., Kate Crawford, Ph.D., and Megan Romano, Ph.D., at Dartmouth College, the research team believes their findings can support the development of consumption guidelines to protect communities from further PFAS exposure.
