The generation of municipal solid waste (MSW) in the US is increasing, putting pressure on environmental and human health. Reducing waste generation and prioritizing waste management pathways alternative to landfilling could ease the environmental burden of MSW. USEPA has develop...

Field-level exercises with the purpose to assess remediation following the deliberate release of a highly toxic chemical in an indoor environment can be conducted using low(er) toxicity simulants if they are closely linked to the behavior of the toxic chemical itself. Experimenta...

The delivery of safe, potable water to communities is the primary objective of drinking water utilities. However, the quality of the water can deteriorate as it is transported from the treatment plant through the distribution system to the customers due to interactions with the p...

The Equitable Resilience Builder (ERB) is a downloadable application that supports communities in strengthening resilience to disasters and climate change, with a focus on equity. It engages users in a guided process to inclusively assess local hazards, equity, and resilience of ...

EPA’s Homeland Security Research Program conducts decontamination efficacy studies that identify technologies that can be used to clean surfaces, materials, or objects contaminated with chemical, biological, or radiological agents. This project consisted of an assessment of...

A release of a chemical warfare agent (CWA) will create an acute and significant exposure risk to the public as well as remediation contractors who would be tasked to cleanup a contaminated site. It would require decontamination of the contaminated area which may hold sensitive e...

Following the SAM update in FY22, and SCID update in FY23, maintenance might be needed on the website that may require contractor support. Restructuring continues from STRAP 3 to get the website and tools more manageable for internal EPA maintenance. Ongoing support for CMS, DMS ...

The COVID-19 pandemic has raised interest in using chemical air treatments as part of a strategy to reduce the risk of disease transmission, but more information is needed to characterize their efficacy at scales translatable to applied settings and to develop methods for evaluat...

1,4-dioxane is a likely human carcinogen and has been found in groundwater and drinking water supplies throughout the United States. Historically, 90% of 1,4-dioxane production was used as a stabilizer in chlorinated solvents, such as 1,1,1-trichloroethane (TCA). The physical and...

This subproduct is a conference presentation to be presented at a suitable scientific conference that summarizes preliminary results from a field evaluation of current EtO measurement methods for near source EtO monitoring. (More details will be added after subproduct is generate...

Residential wood and pellet stoves are important sources of volatile organic compounds (VOCs), particulate matter (PM), and other hazardous air pollutants (i.e., air toxics) that contribute to poor air quality. VOCs released during residential wood combustion (RWC) can react with...

This subproduct is a conference presentation covering ROCS linked to odor app and other odor/air toxics sensor measurements conducted in the Rubbertown area in Louisville, KY. (Abstract to be updated with details after subproduct has been generated).

Industrial and waste management facilities can emit air pollutants and odorous compounds from fugitive leaks, process malfunctions, and area sources that are difficult to predict, quantify, and manage. These sources can produce a range of environmental and life quality impacts an...

Chemicals in industrial and commercial products play crucial roles in the life quality of humankind. But these substances need proper management during their life cycle stages (e.g., manufacturing, use, end-of-life (EoL)) to minimize harmful effects on human health and the enviro...

The United States Environmental Protection Agency (EPA) Office of Research and Development (ORD) is optimizing preconcentration-based gas chromatography/mass spectrometry (GC/MS) analytical methods for determination of ultra-trace concentrations of ethylene oxide (EtO) in ambient...

Ranging from lower cost sensor networks to satellite imaging, advances in Next Generation Emission Measurement (NGEM) technologies are enabling new ways to measure methane emissions from landfills. Over the past decade, research groups have demonstrated multiple landfill measurem...

While per- and polyfluoroalkyl substances (PFAS) have been reported extensively in landfill leachate, discrete sources of leachate from within MSW landfills are not as well understood. Samples of gas condensate (GC) – a liquid formed when water vapor in landfill gas condenses – a...

The purpose of this research is to fundamentally investigate the measurement quality of condensable particulate matter (CPM) via both Method 202 and Other Test Method (OTM)-37 under controlled conditions by understanding both CPM formation mechanisms, and the dynamics that occur ...

Above ground storage tanks/terminals provide an essential link in the transportation of fuel between national infrastructure (e.g., pipelines) and local distribution points (e.g., gas stations). As part of normal operations, volatile components of refined gasoline/fuels (includin...

United States Environmental Protection Agency (EPA) Method 325A/B describes the collection (Method 325A) and analysis (Method 325B) of volatile air toxics compounds by passive or diffusive sampling on thermal desorption (TD) tubes. Method 325B lists diffusive uptake rates (DURs) ...

An abstract for the Air and Waste Management Association's Air Quality Measurements Method and Technology Conference. The proposed talk will discuss progress on the above Primary Research Project. 

Advancement in energy extraction technologies has driven unprecedented expansion of oil and natural gas (ONG) production in many regions of the U.S. Methane, ozone precursors, and hazardous air pollutants, such as benzene, are emitted as part of ongoing ONG production operations....

Improved understanding and control of methane and other air emissions from municipal solid waste landfills is an emerging priority in the U.S. and internationally. However, quantification of emissions from landfills represents one of the most difficult source emission measurement...

Ethylene oxide (EtO) is an important chemical feedstock and a hazardous air pollutant. There is growing interest in understanding and controlling EtO emission sources within chemical facilities to enhance worker safety and limit near-facility exposure potential. In addition to co...

BCP Ingredients is a chemical facility located in Verona, MO that works with significant quantities of ethylene oxide (EtO) as part of normal operations. EtO is a hazardous air pollutant and the citizens of Verona have expressed concerns to EPA Region 7 regarding potential EtO co...
