Chemical concentration versus time (CvT) data is commonly used to characterize the toxicokinetic (TK) properties of chemical substances. However, obtaining in vivo CvT data requires scientific labor and use of animal subjects. To reduce or eliminate new animal testing, it remains...

This subproduct contains text and pictures for an update/extension of the EPA Emergency Response Research's Analysis for Coastal Operational Resiliency (AnCOR) webpage (https://www.epa.gov/emergency-response-research/analysis-coastal-operational-resiliency). It describes the wide...

The U.S. Environmental Protection Agency’s Storm Water Management Model (SWMM) was used to evaluate the potential concentrations and migration pathways of spores spread by urban stormwater following a hypothetical biological agent terrorist attack or accidental pathogen rel...

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 U.S. Environmental Protection Agency (EPA) strives to protect human health and the environment from adverse impacts resulting from incidents involving biological outbreaks or the intentional release of threat agents. Over the last 15 years several interagency efforts have bee...

This study characterized Bacillus globigii (BG) as a Bacillus anthracis Sterne (BAS) surrogate for wastewater treatment-related studies of UV inactivation, adsorption onto powdered activated carbon (PAC), and bioaerosol emission. The inactivation of BG was faster than that of BAS...

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...

The Analysis for Coastal Operational Resiliency (AnCOR) program is an interagency collaboration between the U.S. Environmental Protection Agency (EPA), the Department of Homeland Security (DHS), and the United States Coast Guard (USCG). The overall purpose of this multiagency pro...

Large-scale biological contamination incidents pose unique yet significant challenges to remediation operations. Previous incidents have demonstrated the utility of readily available commercial and municipal equipment for conducting remediation tasks. Pre-identification and evalu...

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

The Water Security Test Bed (WSTB) is a full-scale representation of a drinking water distribution pipe that conveys potable water. It is the product of a partnership between Idaho National Laboratory (INL) and the Environmental Protection Agency (EPA).  Currently, the syste...

Bacillus anthracis and other environmentally persistent pathogens pose a significant threat to human and environmental health. If contamination is spread over a wide area (e.g., resulting from a bioterrorism or biowarfare incident), readily deployable and scalable sample collecti...

Surface decontamination is a method of using wash water to decontaminated surfaces preventing transmission of biological contaminants that can pose potential health risks to responders and the public. However, the risks associated with handling used wash water are largely unknown...

The project team evaluated the device at multiple wavelengths to assess optimal performance under specific conditions for select contaminants and a suite of contaminants.  This collaboration focused on the following:  - Reactor optimization and flow scale-up,  - Mo...

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 study examined the washoff of Bacillus globigii (Bg) spores from concrete, asphalt, and grass surfaces by stormwater.  Bg is a nonpathogenic surrogate for Bacillus anthracis, which is a biological select agent. Areas (2.74 m x 7.62 m) of concrete, grass, and asphalt were ino...

Rapid decontamination following a biological terror incident is paramount for the return of a city’s operations and economy to normalcy. An outdoor urban biological agent incident may require remediation of thousands of vehicles. In this research, the utilization of widely availa...

Drinking water storage tanks serve several important functions, which include but are not limited to providing an adequate water supply in the case of firefighting emergencies, power outages, water main breaks, or other system failures. The water level elevation in storage tanks ...

This summary outlines the current progress US EPA’s Homeland Security Research Program (HSRP) has made through development of scientific products that support capabilities for non-spore-forming biological incident response. These products are meant to advance the body of sc...

Waste is produced at all stages of the response and recovery (including decontamination) following a biological contamination incident. Types of materials that generate a significant proportion of the waste at every stage of the response include personal protective equipment (PPE...

Bacillus anthracis, the causative agent of inhalation anthrax, is one of the most highly studied biological threat agents. Significant gaps remain related to the remediation of a wide area following such biological release. This extends to the remediation of critical assets owned...

This presentation will examine how serious games are being used to enhance the US Environmental Protection Agency’s (US EPA’s) emergency response mission, by improving the ability of the emergency response community to quickly and effectively respond to a range of env...

Background: Site decontamination following a biological contamination event can expose first responders to dangerous microbial agents present. To deploy appropriate site mitigation strategies, microbiological agents present must be identified to ensure proper precautions are take...

To assist in emergency preparedness for a biological agent terrorist attack or accidental pathogen release, potential contaminant levels and migration pathways of spores spread by urban stormwater were evaluated using a Stormwater Management Model (SWMM) of U.S. Coast Guard Base ...
