Communities are searching for technologies to remove and destroy toxic per- and polyfluoroalkyl substances (PFAS), especially when these chemicals are in their drinking water. PFAS have been used in applications such as fire-fighting foam,&nbsp;cosmetics, water- and fire-resistan...

Recently, the U.S. Environmenttal Protection Agency (EPA) adopted a new approach to study and manage environmental problems. In the past, the agency's emphasis was on particular pollutants and their effects on individual species in air, land, and water. But the environment is not...

The SO2 Integrated Review Plan is the first document generated as part of the National Ambient Air Quality Standards (NAAQS) review process. The Plan presents background information, the schedule for the review, the process to be used in conducting the review, and the key policy-...

Causal structural models are used to capture knowledge of a problem domain through framing potential events as random variables and connections as causal arcs. Moreover, the properties of causal structural models foster additional insights on causal and inferential interactions a...

Argonne is building an intelligent computer application, the Radiological Recovery Logistics Tool (RRLT), to assist the understanding and allocation of resources for a mitigation and recovery effort. RRLT output will be a list of recommended methods and tools to accomplish the sp...

Legionella pneumophila (Lp) is an opportunistic pathogen that causes respiratory infections primarily through inhalation of contaminated aerosols. Lp can colonize premise plumbing systems due to favorable growth conditions found within those environments (e.g. lower disinfectant ...

The EPA is enhancing the nation&rsquo;s ability to respond to and recover from a chemical warfare agent (CWA) incident through research to develop environmental countermeasures and response exercises/training. Recently, researchers and responders were brought together to conduct ...

Contamination of surface waters often leads to drinking water contamination, degradation of aquatic biota and their habitat and ultimately the decline of the quality of life for both humans and animals. Pathogen contamination, as determined by bacterial fecal indicators, is the l...

The U.S. Environmental Protection Agency&rsquo;s (EPA) Homeland Security Research Program has been conducting research to evaluate the efficacy of air cleaning and treatment technologies against infectious bioaerosols. The COVID-19 pandemic has increased interest in these technol...

As Ecological risk assessments (ERA) move beyond organism-based determinations towards probabilistic population-level assessments, model complexity must be evaluated against the goals of the assessment, the information available to parameterize components with minimal dependence ...

As part of its ongoing efforts to support implementation of the Toxic Substance Control Act as revised by the Frank R. Lautenberg Chemical Safety for the 21st Century Act, EPA researchers are developing innovative methods to collect and predict exposure estimates for thousands of...

Changes in size at and time to metamorphosis indicate developmental effects in amphibians that could result in population-level impacts. Current risk assessment practice uses early life stage fish data when data for larval amphibians are not available. While fish are sufficiently...
