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...

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...

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 the m...

This EPA report provides information on decontamination options for surfaces contaminated with a fourth generation (chemical) agent. Decontaminants and surfaces were selected based on expected higher material compatibility than e.g., corrosive bleach with materials associated wit...

Under the U.S. Environmental Protection Agency’s (EPA’s) Homeland Security Research Program (HSRP), research is being conducted necessary for identification of methods and technologies that can be used during hazardous materials remediation and cleanup efforts. The th...

The U.S. Environmental Protection Agency was developed to protect human health and the environment by ensuring the nation has clean air, land, and water. Towards this effort, the Agency provides scientific solutions through the development of analytical methods and risk-based hea...

Wide-area remediation following a B. anthracis (Ba) spore release presents many issues including balancing the limited resources available with the need to characterize contamination, conduct decontamination, and management of post-decontamination waste. Capabilities and an opera...

A large-scale release of a chemical, radiochemical, or biological (CBR) agent can result in wide-area contamination and would require significant time and resources for recovery. Several Environmental Protection Agency (EPA) Homeland Security Research Program (HSRP) decision supp...

This report addresses options to improve on the decontamination of permeable materials that are contaminated with a toxic chemical that has transferred into such material. Here, two surrogates of chemical warfare agents are considered to investigate the degree of transport, mater...

Presentation to attendees of the Operational Testing and Evaluation of Chemical Remediation Activities (OTECRA) visitor day  describing the connection between the bench scale research and this full-scale test. The purpose of this field test is to test and evaluate EPA remedi...

This technical brief provides decision makers with a practical summary of recent US EPA scientific information and data related to the technical challenges involved with remediating a fentanyl-contaminated indoor site. The research topics included in this summary are indoor build...

This report addresses the application of low concentration hydrogen peroxide vapor for the remediation of surfaces contaminated with the persistent chemical warfare agents VX and sulfur mustard (HD) and the pesticide (and chemical warfare agent surrogate) malathion. A low concent...

 In all, this presentation will familiarize the audience on the decision support tool’s overall versatility and breadth to which it can support objectives, strategies, and tactics not only for nuclear and radiological releases, but also chemical and biological threat a...

The significant increase in illegal use of the synthetic opioid fentanyl is leading to unintentional overdose fatalities. Spills of fentanyl where it is abused or prepared for illegal distribution can result in persistent contamination of areas. Remediation can be attempted throu...

Motivated by the COVID-19 pandemic, the United States Environmental Protection Agency (EPA) is conducting research to evaluate the efficacy of devices to inactivate SARS-CoV-2 on surfaces in addition or as an alternative to chemical-based disinfectants. Devices that emit ultravio...

To this end, this study partnered with a world-wide supplier of street sweepers to mimic the operation of their sweeper at the laboratory scale in order to study its capabilities and evaluate its efficacy against contaminated dust and dissolved forms of radioactive contamination....

The primary objective of this study was to quantify the dose incurred to workers performing a remediation recovery effort for roadways and buildings following a wide-area release event.

This presentation provides an overview of EPA’s potential role in a fentanyl consequence management response and contains the results from decontamination research that was initiated to fill select gaps identified during the development of EPA’s Fentanyl Fact Sheet fo...

A large-scale release of a chemical, radiochemical, or biological (CBR) agent can result in wide-area contamination and would require significant time and resources for recovery. Several Environmental Protection Agency (EPA) Homeland Security Research Program (HSRP) decision supp...

The U.S. Environmental Protection Agency’s Homeland Security Strategic Research Action Plan was established to advance EPA’s capabilities to recover from a wide-area contamination incident, and the study described in this report supports that objective. This small study evaluated...

Illicit use of the potent opioid fentanyl and its analogs (fentanyls) is on the rise in the US, leading to an epidemic of overdose deaths. As illicit use increases, more locations can be contaminated through the synthesis, mixing, and preparation for use. Because of worker safety...

This report assesses decontamination options for fentanyl contaminated building materials as well as responder gear and personal protective equipment related materials. This report builds on a previous fentanyl decontamination efficacy study that looked at other decontaminants. T...

Through an intelligent software wizard, the RRLT helps the user understand what types of equipment might be available to accomplish general and specific recovery mission activities based on environmental and operational constraints. The purpose of the RRLT is to increase the resi...

While some fast-response dispersion models can capture the effects of individual buildings, research is required to further refine urban characterizations, especially within the presence of a nonhomogeneous array of structures. This project leverages the configuration of building...

In the event of a chemical, biological, radiological, or nuclear (CBRN) wide-area incident, the U.S. Environmental Protection Agency (EPA) is responsible for clearance, waste disposal processes, and data collection and quality checks to advise decision-making. This research effor...
