The United States Environmental Protection Agency (US EPA) conducts extensive research to enhance the scientific foundation for national environmental decision-making. In this context, US EPA has developed COMET (City-based Optimization Model for Energy Technologies) to capture t...

The 2007 NAS report on Toxicity Testing for the 21st Century was a watershed moment for toxicology. Since then, the discussion is no longer whether to change but how and how fast? With knowledge in the life sciences doubling every seven years, we now have four times more understa...

Suffolk County, New York is the eastern-most county on New York’s Long Island and is surrounded on all sides by coastal embayments impaired due to excess loading of nitrogen. Sources of nitrogen include atmospheric deposition and loading via groundwater from agricultural an...

EPA/ORD developed City-based Optimization Model for Energy Technologies (COMET) which is designed to examine energy consumption and management scenarios under various environmental policy scenarios implemented at city- and state-level. Initial application of the COMET is piloted ...

Scientists in the United States and Canada have collaborated on the Cross-Appalachian Tracer Experiment (CAPTEX '83) using the perfluorocarbon tracer to simulate the long-range transport of pollutants in the atmosphere. The experiments, conducted in September and October of 1983 ...

This report provides a comprehensive overview of the literature review and technology screening conducted for critical mineral (CM) extraction from mine wastes and mining-influenced waters (MIW). The primary objectives were to identify and evaluate technologies that could potenti...

Sodium fluoroacetate is a highly lethal pesticide, which is registered for use to control livestock. It does not have a known antidote and is stable in potable water. If a water contamination incident with this pesticide were to occur, a fast, robust analytical method would be ne...

The Adaptation Design Tool of the Corals & Climate Adaptation Planning project has been developed to help coral reef managers incorporate climate-smart design into their plans, programs, and projects at any stage of planning and implementation. It can be used to incorporate c...

The technology profile was developed to provide contaminated site staff with insights on the potential use of phytotechnologies at contaminated sites. 

The Scenarios and Interpretive Science Coordinating Group (SISCG) is an interagency coordinating group, supporting the U.S. Global Change Research Program (USGCRP). The SISCG convened the Towards Scenarios of U.S. Demographic Change Workshop in Rockville, Maryland on June 23 and ...

We reviewed the available social-ecological, hydrological, and geochemical literature for the ecological systems of the San Juan Bay Estuary (SJBE), a site in the Environmental Protection Agency’s National Estuarine Program. The objective of the review is to gather in one place a...

Like many coastal communities, the City of Crisfield, Maryland, is experiencing increased inundation due to sea level rise (SLR), land subsidence, and intensifying extratropical storms. The U.S. Environmental Protection Agency (EPA) Office of Research and Development (ORD) has pa...

In this document, the Modeling Advisory Group notes that overall, is was impressed with the SFEI science team and the pace of progress on model development, validation, and application. The report notes that model validation is iterative exercise, so the MAG proviedes findings an...

We present an applied study estimating beach visitation in southern California, USA using data dervied from mobile device location data. As an emerging tool for visitation analysis, these data provide the ability to monitor visitation and large scale and fine geographic and tempo...

A free and publicly open virtual workshop was held in September 2024 to communicate EPA’s Homeland Security Research Program’s (HSRP) work on modeling stormwater transport of radionuclides. Since stormwater modelers do not often work with scenarios pertaining to radioactivity, th...

Building from our field studies in Missoula, MT and Hoopa, CA (including building inspections) and our work with the ASHRAE (formerly the American Society of Heating, Refrigerating, and Air-Conditioning Engineers) Committee developing ASHRAE Guideline 44-2024: Protecting Building...

This report will describe the methods for creating factors for representing embodied carbon in carbon dioxide equivalents for U.S. imports by commodity and region. The factors are derived using a coupled model approach from the EXIOBASE v3 multi-regional input-output model.
