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...

Aims: This study aimed to provide operationally relevant SARS-CoV-2 surface disinfection efficacy information. Methods and Results: Disinfectants were evaluated against SARS-CoV-2 on material coupons and were tested using Spray (no-touch with contact time) and Spray & Wipe (wipe...

Landfill gas (LFG) extraction wellhead data were compared to understand the range of observations due to unique conditions at five elevated temperature landfills (ETLFs) in the US. Correlations of CH4 and CO2 show distinct compositional indicators for 1. typical operation, 2. sub...

Burn pits are a method of open-air waste management that was common during military operations in Iraq, Afghanistan, and other regions in Southwest Asia. Veterans returning from deployment have reported respiratory symptoms, potentially from exposure to burn pit smoke, yet compre...

This presentation describes the development of a decision support tool, the Priority Response Environmental Screening Tool (PRESTO), that was designed to provide a framework for analyzing geospatial information. The objective of a PRESTO analysis is to assist the U.S. Environment...

Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that have been in use since the 1940s in a wide array of consumer products. PFAS are persistent in the environment and bioaccumulate. Thermal treatment methods are currently applied to a variety of mater...

This presentation is Part 2 consumption-based GHG emissions inventory for the state of Maine. This presentation is focused on results of the study, interpretation, and identifying opportunities for further exploration.

Extreme weather events make it critical for communities to plan for effectively managing large quantities of disaster waste and debris while maintaining their ability to receive everyday municipal waste. Recent disasters – floods, hurricanes, earthquakes, tsunamis, fires, v...

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’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 ...

The U.S. Environmental Protection Agency’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...

The Gulf of Mexico receives inputs from numerous tributaries that discharge natural organic matter (NOM) and other natural photosensitizers to its coastal beaches. Much of this NOM is colored dissolved organic matter (CDOM) which affects photoreactions of contaminants by light at...

The U.S. Environmental Protection Agency and Sandia National Laboratories have developed the Water Network Tool for Resilience (WNTR) to quantify resilience of drinking water distribution systems. WNTR is a Python package designed to simulate disaster scenarios and analyze impact...

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 ...

EPA is developing a regulation for perchlorate in drinking water. As part the regulatory process EPA must develop a Maximum Contaminant Level Goal (MCLG). FDA and EPA scientists developed a biologically based dose-response (BBDR) model to assist in deriving the MCLG. This mode...

EPA is developing approaches to inform the derivation of a Maximum Contaminant Level Goal (MCLG) for perchlorate in drinking water under the Safe Drinking Water Act. EPA previously conducted an independent, external, scientific peer review of the draft biologically-based dose-res...

Ricin is a highly toxic protein, capable of inhibiting protein synthesis within cells, and is produced from the beans of the Ricinus communis (castor bean) plant. Numerous recent incidents involving ricin have occurred, many in the form of mailed letters resulting in both buildin...

The U.S. Environmental Protection Agency (EPA) Engineering Issue Papers (EIPs) are a series of technology transfer documents that summarize the latest information on selected waste treatment and site remediation technologies and related issues and present it in a conveniently acc...

Drinking water utilities are vulnerable to both human-caused and natural disasters that can impact the system infrastructure and the delivery of potable water to consumers. Resilience analysis can help utilities identify high-risk areas in their system and understand how to bette...

Many aqueous film forming foam (AFFF) delivery systems in aircraft hangars and firefighting vehicles may require thorough cleaning to avoid ongoing environmental impacts from residual per- and polyfluoroalkyl substances (PFAS) within those systems. Though replacement AFFF formula...
