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 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...

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...

Radiological release incidents can potentially contaminate wide areas with radiological materials and decontamination efforts are typically focused on populated areas leaving radionuclides in forested areas for long periods of time. Large wildfires in contaminated forested areas ...

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...

Enhancing rapid remediation strategies is paramount for recovery after a large-scale nuclear contamination event in an urban environment. Some current strategies recommend use of readily available equipment, materials, and facilities to expedite recovery. For example, applying pr...

Virus adsorption to colloidal particles is an important issue in the water quality community. Namely, if viruses can quickly and strongly associate to colloids, this can potentially lead to significant implications for management of biohazardous wastes at water resource recovery ...

Presentation

This product is a book chapter intended for an edited volume on disasters and culture. It stems from a plenary panel at the 2018 Society for Applied Anthropology meetings, where the four panelists (now co-authors) addressed the four questions that frame the chapter. The intended ...

In the aftermath of a wide-area radiological contamination incident in an urban setting, there is the potential for generation of significant quantities of contaminated biomass waste. These wastes are likely candidates for incineration as a means of volume reduction, due to the c...

This study aims to understand the effect of the rapid decontamination methods of high pressure washing and washing with salt additives on the penetration of radionuclides into concrete. To this end, we first identified how penetration profiles of Cs-137, Sr-85, and Eu-152 evolve ...

Sensitivity analyses on the system parameters revealed simple relationships between the bed design and the expected breakthrough of cesium, allowing us to generate a concise set of look-up tables to aid the early responders.

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...

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...

Develop readily available and scalable technologies and software tools to support water and wastewater infrastructure decontamination and the treatment of contaminated water. Develop and verify plans for all phases of environmental cleanup for facilities, equipment, and the env...

In an increasingly connected world, integrating a One Health approach is needed to better assess risks posed by biothreat agents and for developing effective, environmentally-sustainable response strategies. One Health recognizes the interaction and interconnectedness of human, a...

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.

Understanding the survival mechanisms of Legionella within building water systems (BWSs) is challenging due to varying engineering, operational, and water quality characteristics unique to each system. Disinfectant residual and detection of the amoeba hosts, Acanthamoeba spp. an...

Presentation on EPA's activities supporting USDA for animal carcass disposal

The presentation will describe the air monitoring EPA is doing for the grinding project for African Swine Fever preparedness.

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...

In the aftermath of a wide-area radiological contamination incident in an urban setting, there is the potential for generation of significant quantities of contaminated biomass waste. These wastes are likely candidates for incineration as a means of volume reduction, due to the c...

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
