EPA Research

EPA Research in the States

EPA researchers are conducting innovative, anticipatory research and applying their expertise to a range of environmental challenges including helping states and communities make informed decisions about environmental issues they face. You can view some of that research here. EPA research supports all states. This page features select stories to highlight how EPA research benefits states.

States colored blue in the map below have stories showcased here, and gray states do not have stories featured on this page.

Research across States

  • Mapping Mercury in the Western U.S.

    The western United States is disproportionately impacted by mercury pollution due to historic metals mining, natural geologic processes, local emissions, and trans-pacific transportation. Scientists from ORD and Regions 8, 9, and 10 partnered with the US Geological Survey and the National Park Service to gather decades of site-specific mercury data to create a comprehensive mercury cycling model. Regional and state officials are using this model to make remediation decisions at mercury-impacted impacted sites and evaluate proposals for new mining sites.

  • Optimizing Drinking Water Treatment Practices

    Algal toxins pose a significant challenge for water treatment plants due to their unique ability to spread rapidly within a drinking water supply. ORD and Region 5 collaborated with public water utilities along Lake Erie to identify the best approaches for removing algal toxins through drinking water treatment processes. The project team provided utilities and regulators across the US with technical recommendations for reducing the spread of algal toxins by changing the water pH and the order of adding treatment ingredients.
