The Equitable Resilience Builder (ERB) is a newly released tool to support community resilience planning. ERB is a downloadable application that supports communities in strengthening resilience to disasters and climate change. It walks a core team of users through a guided proces...

Genomic biomarkers have the potential to reduce the need for conventional rodent cancer bioassays when used in a weight-of-evidence manner together with other classical and mechanistic information from shorter term studies. In a cross-sector initiative, our goal is to develop gen...

The US EPA wrote the New Approach Methods Work Plan in 2021 to 1. Develop NAMs to address information gaps, 2. Engage and communicate with stakeholders, 3. Establish scientific confidence and demonstrate application, 4. Develop baselines and metrics, and 5. Evaluate regulatory fl...

This is a presentation to Air Resource Advisors (ARAs) affiliated with the Interagency Wildland Fire Air Quality Response Program (IWFAQRP). ARAs are technical specialists who are deployed to wildfire incidents to provide smoke monitoring, modeling, and communications support. Th...

The fugitive emissions of volatile organic compounds (VOCs) from industrial processes are currently managed through in-person leak detection and repair (LDAR) efforts that are costly and occur periodically. These emissions are not rigorously accounted for in current emissions inv...

This is a presentation to the Water Treatment Interagency Working Group and is a summary of EPA/ORDs water sensor research effort, focusing on drinking water applications.&nbsp;

Reliable and comprehensive PFAS and PFAS-related emission measurement methods are needed for multiple purposes with some in use. Efficacy of combustion and non-combustion applications is important for all media and waste types with encouraging results and laboratory tests continu...

Residential wood and pellet stoves produce smoke that contains multiple pollutants such as particulate matter (PM), volatile organic compounds (VOCs), and a plethora of other hazardous air pollutants (HAPs) that can contribute to poor air quality. VOCs from residential wood combu...

Perfluorooctanoic acid (PFOA) and perfluorooctanoic sulfonic acid (PFOS) are two legacy per- and polyfluoroalkyl substance (PFAS). PFAS have been widely used in the past and commonly measured at various concentrations in many wastes and environmental media. Thermal treatment tech...

U.S. EPA released two free tools to help users visualize their air data. REal TIme Geospatial Data Viewer (RETIGO) is an easy to use, web-based tool which requires no coding skills and can be used with any type of measurement device. Users can visualize their data and compare it ...

Unmanned aircraft systems (UAS, or drones) have been used to characterize emissions from prescribed forest and grassland fires.&nbsp;

Water quality standards are important for protecting and restoring the condition of lakes, rivers, estuaries, and other water bodies in the United States. Given that nutrient pollution continues to be a widespread problem in aquatic systems, the development of numeric nutrient cr...

Microplastics are ubiquitous in the environment and present potential adverse effects on human and environmental health. EPA's Office of Research and Development is interested in developing sampling and analytical methods for microplastic detection, investigating their effects on...

Emerging contaminants of concern (ECCs), such as flame retardants and per- and poly-fluoroalkyl substances (PFAS), are frequently detected in various environmental compartments and biological matrices/species due to widespread use and release through different exposure pathways. ...

Describes health effects of PFOA and provides values for region and state use.

Describes the health effects of PFOS and provides values for region and state use.

The Small Communities - Big Challenges Competition was a ORD and OEJECR sponsored Challenge and Prize Competition that was open to local governments to highlight innovative and inclusive strategies for engaging with rural communities and collaboratively identifying environmental ...

Identifying reliable positive and negative control compounds is integral to determining the sensitivity and specificity of chemical assays. Our laboratory screens chemicals for developmental neurotoxicity potential using assays that assess larval zebrafish locomotor behavior in r...

Background: Mechanistic understanding of transient exposures that lead to adverse health outcomes will enhance our ability to recognize biological signatures of disease. Here, we measured the transcriptomic and epigenomic alterations due to exposure to the metabolic reprogramming...

Excess nutrients (nitrogen and phosphorus) in lakes can lead to eutrophication, hypoxia, and algal blooms that may harm aquatic life and people.&nbsp;&nbsp;Some U.S. states have established numeric water quality criteria for nutrients to protect surface waters.&nbsp;&nbsp;However...

The presentation prevents an overview of ORDS research on risk assessment and systems analysis of decentralized water reuse approaches to a group of graduate students in an interdisciplinary program on science, technology, engineering, and policy. The organizers are interest in p...

Presentation will be delivered at EPA webinar (Innovations in Environmental Science) and at ACS Fall Meeting. Overview of ongoing F3 research. Investigating the impacts of novel PFAS-free AFFF on environmental and human health is necessary to ensure they are safer, sustainable, a...

New chemical formulations are being tested to replace PFAS-containing fire-fighting foams in several applications, including systems designed to protect aviation fuels, weapons, chemical tankers, and large petroleum tanks. The current efforts are focused on identifying and synthe...

This is the presentation based on the abstract, ORD.0.0.0.382.   What does it take for a good scientific idea to survive the political lawmaking process? How can scientists and engineers contribute to this effort from inside the legislative branch? For the year 2022, the author h...
