This document provides step-by-step instructions for the use of swabs, wipes, and sponge-sticks to collect samples from surfaces potentially contaminated with microbiological agents. It is intended to be used in conjunction with the analytical methods listed in U.S. Environmental...

&nbsp;In all, this presentation will familiarize the audience on the decision support tool&rsquo;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...

This study investigated formaldehyde decontamination efficacy against dried Bacillus spores on porous and non-porous test surfaces, under various environmental conditions. This knowledge will help responders determine effective formaldehyde exposure parameters in to decontaminat...

In the event of a wide-area release of Bacillus anthracis spores, soils and other outdoor materials may become contaminated with the biological agent. A study was conducted to assess the in-situ remediation of soil using a dry thermal treatment approach to inactivate a B. anthrac...

Summary of EPA ORD HSRP's research to build wide-area response capabilities for biological incidents.The attached product is the powerpoint slides that will be used to present at the UK Modelling of Cleaning and Disinfection Workshop, on April 20-22, 2021. The meeting is a virtua...

A rapid analytical method for detection of infectious (live) SARS-CoV-2 in environmental surface samples (e.g., swabs) was needed to better understand the surface transmission of this virus and to support environmental epidemiological investigations. To address this need, a proof...

HSRP performs applied research that delivers relevant and timely methods, tools, data, technologies, and technical expertise in support of federal, regional, state, tribal, water systems, and local community resilience. HSRP has engaged partners to identify the high priority home...

Large-scale disasters have the potential to generate a significant amount of waste. For example, Hurricane Katrina and the Joplin Missouri tornado resulted in 100 million and 1.5 million cubic yards of waste, respectively. Man-made chemical, biological, radiological, or nuclear (...

Controlled resuspension experiments were performed to understand how the rate of Bacillus spore resuspension changes over time and under the influence of variable meteorological conditions. Two coupon types (concrete and asphalt, 66 of each type) representing surfaces typically f...

Technical report documenting surface sample collection by traditional methods (sponge wipe, vacuum cassettes) on surfaces common to US Coast Guard assets, over a 6-month duration. Culture- and molecular-based analysis methods were evaluated for sensitivity from these samples. In ...

This product is a final report on the project on “Evaluation of Analytical Methods for Detection of Bacillus anthracis Surrogate Spores: Compatibility with Real-World Maritime Environmental Samples Collected from the U.S. Coast Guard (USCG) Assets and Facilities.” In this effort,...

Evaluation of surface sampling methods for USCG assets, following a biological contamination incident.&nbsp;

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....

Introduction. This effort investigated formaldehyde vapor characteristics under various environmental conditions by the analyses of air samples collected over a time-course. This knowledge will help responders achieve desired formaldehyde exposure parameters for decontamination ...

This study evaluated the effect of two biocontaminant surrogates on the activity and performance of activated sludge. In the presence of bacteriophage MS2 at 3.2 × 108 PFU/ml, the peak respiration rates varied between 9.1 and 10.5 mg O2/gVSS/hr, generally similar to the rates obs...

Homeland Security Research program overview and emerging challenge research projects. Advance EPA’s capabilities and those of our state, tribal, and local partners to respond to and recover from wide-area contamination incidents Improve the ability of water utilities to prevent, ...

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...

Aims: To obtain quantitative efficacy data of two ultraviolet light (UVC) technologies for surface inactivation of Bacillus anthracis Ames and Bacillus atrophaeus spores. Methods and Results: Spores were deposited onto test coupons and controls of four different materials, via l...

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 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...

The goal of the literature review was to observe the methods by which other researchers have attempted to model interconnected infrastructure systems. A series of books and journal articles on the subject of modeling complex systems of systems (SoS) and interconnected critical in...

This report summarizes the current scientific literature on remediation-related activities associated with US Coast Guard vessels and other assets. It also provides descriptions of research gaps and needs for consideration by US Coast Guard and other federal agencies to improve o...

Urban areas create complex wind flow patterns that can affect contaminant dispersion downwind of a harmful release. This can result in challenging&nbsp;situations for local officials or emergency responders who must plan for or remediate infrastructure after major chemical, biolo...

This is a power point presentation that summarizes the potential for phototoxicity of crude and refined oils. The presentation will cover the phototoxic components of oil, mechanisms of petroleum phototoxicity, and the environmental and biological modulation of phototoxicity.

This presentation is a compliation of overview and highlights of homeland security research areas in preparation of for chemical, biological, and radiological wide area incidents.
