Building occupants face diverse biological threats, from intentional attacks with biological agents (e.g., weaponized spores), to contagious diseases. As a result of the COVID-19 pandemic, there has been an increasing awareness of and interest in mitigation strategies for reducin...

The primary objective of the Analysis for Coastal Operational Resiliency (AnCOR) Systems for Helping Inform Practice and Protocol (SHIPP) training is to train USCG personnel and refine both existing and newly developed systems to bolster the USCG's ability to respond to biol...

The COVID-19 pandemic has raised interest in technologies that are intended to reduce concentrations of infectious aerosols, which can potentially reduce the risk of disease transmission and improve overall indoor air quality, through either pathogen capture or inactivation. It h...

Technologies that can reduce concentrations of airborne microorganisms through either particle capture or inactivation are important tools for reducing the risk of disease transmission and improving overall indoor air quality. The effectiveness of these technologies is tested in ...

This presentation provides an overview of EPA’s role in a fentanyl response and demonstrate sampling and decontamination approaches based on results from research that was initiated to fill select gaps identified during the development of EPA’s Fentanyl Fact Sheet for...

Following a chemical, biological, or radiological (CBR) incident, a safe corridor is needed for movement of military/civilian personnel and material through contaminated areas. To illustrate, secondary resuspension of radioactive particle contamination due to mechanical means, su...

A large-scale release of a biological agent such as Bacillus anthracis would require very complex and potentially daunting remediation efforts. Significant progress has been made in developing capabilities and preparedness for indoor biological contamination incident response. Ho...

EPA has been conducting systematic testing using a large-scale bioaerosol test chamber (3000 ft3) with a recirculating mock heating, ventilation, and air conditioning (HVAC) duct to evaluate the efficacy of these technologies against aerosolized bacteriophage MS2, as a surrogate ...

When an environmental catastrophe resulting in contamination occurs, whether from intentional incident such as a terrorist attack or an unintentional incident such as an industrial spill, emergency responders and decision-makers need timely and accurate data. This need for data c...

This document provides step-by-step instructions for the use of a 37-mm filter cassette (mixed cellulose ester [MCE] or a polytetrafluoroethylene [PTFE] filter), air sampling pump, and microvacuuming techniques to collect samples from porous surfaces potentially contami...

This report documents notes from a workshop held February 8th, 2024 in Raleigh, NC co-sponsored by North Carolina State University's Biological and Agricultural Engineering Extension program and The United States Environmental Protection Agency focused on the fate and transport o...

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...

This report describes the outcomes from the full-scale Operational Test and Evaluation of Chemical Remediation Activities (OTECRA) field study. OTECRA was conducted to operationally test and evaluate current capabilities to remediate an indoor environment following a simulated ch...

During StRAP 3 flushing of green infrastructure was studied to determine if spores would stay in permeable pavement and biofilters or if they could be removed. This subproduct is the dissemination of this research via a workshop co-sponsored with North Carolina State University's...

The personnel decontamination (decon) line is an essential part of emergency response efforts following a biological agent release for ensuring containment and minimizing exposure risk to potentially biohazardous materials on responder personal protective equipment (PPE). EPA has...

The impact of water and the wet-dry cycle was examined as a potential mitigation solution to pathogenic bacterial spore transport and inhalation risk via resuspension of spores from surfaces due to human activities. The natural occurrence of wet-dry cycles and the ease of applica...

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...

Report on the Wide Area Demonstration (WAD) under the Analysis for Coastal Operational Resiliency (AnCOR) project. The AnCOR WAD was conducted from May 2 through May 27, 2022. The test venue was located at Fort A.P. Hill (FAPH), Bowling Green, VA. All work will was conducted at F...

The COVID-19 pandemic illuminated gaps in viral disinfection data for personal protective equipment and materials typically laundered at home. In support of responders, decision makers, and the general public’s questions concerning the use of different cleaning methods, the Unite...

This report summarizes novel air sampling research conducted for the multi-agency Analysis for Coastal Operational Resiliency (AnCOR) program which sought to develop and demonstrate capabilities and strategic guidelines to prepare the US for a wide-area release of a biological ag...

This product is an interim data report for an ongoing project. The overall goal of this project is to provide the general public, emergency responders, and healthcare workers with initial information on the effectiveness of selected disinfection/cleaning technologies and commerci...
