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...

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...

Should biosolids be contaminated with an intentional malicious release or natural outbreak of Bacillus anthracis spores, a water resource recovery facility (WRRF) may need to consider if their treatment processes can sufficiently inactivate this pathogen. Three methods commonly e...

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 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...

Analytical methods exist to detect biothreat agents in environmental samples during a response to biological contamination incidents. However, the coastal zone facilities and assets of the United States Coast Guard (USCG), including response boats in diverse geographical areas an...

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...

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...

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...

Ricin is a highly toxic protein that is produced from the castor bean plant.  Incidents with using ricin as a terrorist weapon have become more commonplace in recent years. This study examined a technique (Low Concentration Hydrogen Peroxide Vapor; LCHPV) to decontaminate ma...

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...

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...

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 ...

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...

Clean up activities following wide-area release of a persistent biological agent has the potential to generate significant quantities of waste materials. Management of these large quantities of waste typically would involve movement of the materials from the point of generation t...

This presentation provides an overview of the Analysis for Coastal Operational Resiliency (AnCOR) program, an interagency effort to assess and improve capabilities and strategic guidelines to prepare the U.S. for a wide-area release of a biological agent, including mitigating imp...

Literature review report identifying articles that describe surrogates for Bacillus anthracis, enhancements to those surrogates that make them more suitable for environmental studies, and identification of potential further enhancements that could further increase thier detection...

This investigation examined the impact of four liquid sporicidal decontaminants (used for Bacillus anthracis (anthrax) spore inactivation) on metals, plastics and laminates.  In addition, the study evaluated the material compatibility with small equipment, i.e., electrical switch...

This technical brief is a summary of US EPA research publications providing input to solving the technical challenges involved with remediating a large urban area following a contamination incident involving spores of B. anthracis, the causative biological agent for anthrax disea...

This study was conducted to help the USCG recover rapidly following a biological contamination incident and return assets to duty. Determination of asset contamination status is necessary to make decisions regarding asset safety and deployability. The outcome of the study describ...

CESER/HSMMD is conducting research to investigate the reaerosolization of surrogate bacterial spores in the Aerosol Test Facility and through field tests to determine the most representative air sampling methods to use for detection (characterization) and clearance of large outdo...

Aims: The purpose of this study was to evaluate the decontamination efficacy of liquid formaldehyde solutions in various soil types against spores of Bacillus anthracis (B.a.) and potential surrogate spore Bacillus atrophaeus (B.g.). Methods and Results: B.a. and B.g. were inocu...

Sub-product reports the evaluation and development of sampling extraction and processing procedures for difficult matrices samples. Such samples may contain high organic and environmental material, which will be challenging to process and analyze using the existing bio agent samp...
