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...

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...

This website update provides a summary of efficacy testing with the Knorr 3-Stage Air Filtration and Purification System in a large aerosol test chamber with a recirculating HVAC system. The unit's efficacy was evaluated against aerosolized MS2 (a bacteriophage).

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...

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...

Under the U.S. Environmental Protection Agency&rsquo;s (EPA&rsquo;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...

Presentation and sampling procedure handouts to be used during sampler virtual training for AnCOR WAD demonstration. As part of the AnCOR project, a wide area demonstration (WAD) of decontamination of USCG assets in an urban area with a Bacillus anthracis surrogate will take plac...

Data report on UV disinfection results of materials contaminated with SARS-CoV-2 or two potential surrogates thereof. Data report is intended for publication on the ORD CoVID -19 environmental research webpage

This website update provides a summary of efficacy testing with the RGF Photohydroionization® (PHI) technology in a large aerosol test chamber with a recirculating HVAC system. The unit's efficacy was evaluated against aerosolized MS2 (a bacteriophage).

Second update to the ORD CoVID-19 Environmental Research website on UVC disinfection.

Although SARS-CoV-2 is primarily an airborne risk, the COVID-19 pandemic also highlighted the need for self-disinfection surfaces that could withstand the demand of high occupant densities characteristic of public transportation systems. The aim of this study was to evaluate the ...

Journal article; Aims: To obtain data on the efficacy of two ultraviolet light (UVC) technologies for inactivation of Bacillus anthracis Ames and Bacillus atrophaeus spores on surfaces.

The results of this research will provide the EPA response community as well as other Federal, State, Tribal and Local agencies on tools to decontaminate porous materials in the indoor environment that are contaminated with CWAs. Report on bench-scale experimental evaluation of p...

Presentation to FDA on surface disinfection by UVC light during meeting with EPA including OCSPP

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...

The COVID-19 pandemic has highlighted the role that airborne transmission can play in the spread of disease. Consequently, there has been an increasing focus on technologies that claim to reduce or eliminate aerosolized pathogens in indoor occupied spaces. There are many differen...

This technical brief compiles data from several recent U.S. Environmental Protection Agency (EPA) bench-scale studies which assessed the fate and transport of these two chemicals into porous and/or permeable materials. This summary provides decision¿makers with practical informat...

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...

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...

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...

This research will help states, tribes, local, and territorial governments, including public health agencies, guide homeowners, business owners, and workplace managers to reduce the risk of exposure to SARS-CoV-2. Abstract on EPA Research to Support Reducing Environmental Transmi...

Reducing the risk of exposure to SARS-CoV-2, the virus that causes COVID-19, relies on effective cleaning and disinfection, along with public health strategies like testing and social distancing. Recent studies have indicated that exposure to aerosolized SARS-CoV-2 can facilitate...

EPA has conducted numous laboratory studies to evaluate cleaning, disinfection, air cleaning, and other approaches for reducing exposure to SARS-CoV-2. This presentation will summarize those research efforts and the high-level findings.

Presentation to the International Ultraviolet Association on the UV disinfection rserach agaisnt SARS-CoV-2 virus on relevant surfaces

This presentation provides an overview of EPA&rsquo;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&rsquo;s Fentanyl Fact Sheet fo...
