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...

On May 8-10, 2018, the U.S. Environmental Protection Agency’s (EPA’s) Office of Research and Development’s National Homeland Security Research Center (ORD/NHSRC) hosted the 10th U.S. EPA International Decontamination Research and Development Conference at the EPA facilities in Re...

This report describes a streamlined bench scale procedure which has been developed for testing the efficacy of chlorine bleach for the inactivation of Bacillus spores in wash water originating from a cleanup of a site contaminated with Bacillus anthracis spores.

The sorption and desorption properties of radionuclides onto common building materials such as concrete are critical factors in the improvement of techniques for mitigating a release of nuclear or radiological material to the urban environment. A potential option for the early p...

Atmospheric dispersion models have frequently been used around complex industrial sites or in urban areas where building effects are predominant. Urban structures tend to considerably modify the local flow, potentially impacting concentrations from hazardous releases. These dispe...

This presentation will address capability gaps related to sampling, fate & transport, decontamination, data management, and waste management. Local and state responders can benefit from this research with new information and tools to ensure community resilience to a wide area bi...

The Underground Transport Restoration (UTR) Operational Technology Demonstration (OTD) was a full-scale study focused on remediation of a subway system after contamination with a Bacillus anthracis (Ba) surrogate (Bacillus atrophaeus, subspecies globigii [Bg]). The study involved...

Under U.S. Environmental Protection Agency’s Homeland Security Research Program (US EPA HSRP), the National Homeland Security Research Center conducts research necessary to identify methods and technologies that can be used for the decontamination of equipment and surfaces contam...

This effort sought to assess the impact of potential real-world interferents (RWIs) present in Sponge-Stick and Vacuum Cassettes (VCF) samples on current culture and molecular analysis methods. Having an assessment of the impact, if any, will help EPA understand limitations of th...

This technology evaluation report included use of low-tech decontamination methods on surfaces common to outdoor residential environments and included evaluating the decontamination efficacy, method constraints, safety concerns, feasibility, waste generation, potential exposure, ...

In the present study, we quantified how well an activated carbon (AC) sample maintained its adsorption capacity for Methyl bromide (MeBr) over several adsorption/desorption cycles, using three different gas conditions. During the adsorption phase, the AC was exposed to a feed gas...

High pressure decontamination of certain surface building materials is concluded to be a promising rapid, readily available response technique, with the data from this study informing its practical implementation. Removal efficacy of radionuclides from concrete are high when perf...

The effect of sporicidal fumigation with methyl bromide or methyl iodide on the functionality of electronic equipment was evaluated using desktop computers as surrogates for valuable electronic equipment under target conditions of 200–250 mg/L fumigant for 48 hours at 24–30 °C an...

EPA’s National Homeland Security Research Center (NHSRC) coordinated a one-day workshop on Vehicle Waste Management and Disposal, which was held on Monday, November 13, 2017, at EPA’s Potomac Yard South located in Arlington, Virginia. The workshop brought together officials from ...

Francisella tularensis, the bacterium that causes Tularemia infection, is a high-priority bioterrorism agent. There is no step‐by‐step analytical protocol for detection of Francisella tularensis in environmental samples that can be used by the EPA’s Environmental Response Laborat...

This brief provides a summary of two recent U.S. Environmental Protection Agency (EPA) bench-scale studies assessing the persistence of VX on various building material surfaces. This overview provides decision‐makers with practical information on the expected persistence of VX fo...

The potential exposures and exposure pathways were compared for various options to support decision-making in the event of a radiological emergency to provide an in-depth evaluation based on understanding of ionizing radiation and radiation exposure, conceptual models of potentia...

Although the military has been developing decontamination methods for their purposes for decades, research conducted or funded by nondefense government agencies with a focus on the decontamination of civilian facilities had been minimal prior to 2001. That changed following the i...

Following a biological contamination incident, the spatial extent of the contamination should be determined using established sampling and analytical methods such as culture or RV-PCR. A previous study demonstrated that a sampling strategy involving native air samplers could be i...

Technical Brief

Improving the way in which information is shared amongst decision makers, scientists, and responders, as well as models and decision support systems, is critical to the success of any response or recovery operation. Current data sharing capabilities exist; however, the ability to...

An analytical method was optimized for MS2 recovery from simulated agricultural surfaces. Considerations included selection of a neutralizer and extraction buffer, determination of analytical holding time, and MS2 survivability on surfaces with and without grime. The decontaminat...

Presentation; The study was devised to connect emergency management and homeland security offices at the city, state, and federal agencies and discuss the availability and potential response capabilities of equipment reserves.

This presentation provides the EPA/NHSRC perspective on the UK Novichok incidents from 2018 with a focus on the waste management of the created waste. The slides for The 37th International Conference on Thermal Treatment Technologies & Hazardous Waste Combustors, League City, TX

The Weather Data Tool is a command line interface application written in Python that facilitates the acquisition of time series precipitation data from national Forecast and Historical weather data providers; and generates an output file to be consumed by the EPA Storm Water Mana...
