A Stochastic Model for Evaluating Interconnected Critical Infrastructure Decontamination and Recovery (PRESENTATION)
Large-scale chemical, biological, radiological, and nuclear (CBRN) incidents have the potential to impact a wide area that would include core infrastructure assets. In such an event, the impact may extend beyond directly affected infrastructure sectors due to the interconnected n...
A case study of cesium sorption onto concrete materials and evaluation of wash agents: Implications for wide area recovery (JOURNAL)
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...
A comparison of building effects simulations in different atmospheric dispersion models with detailed sonic measurements from the Jack Rabbit II field experiment (PRESENTATION)
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...
Assessment of Non-Destructive Decontamination Methodologies for Mixed Porous Surfaces: Aging of Technology under High Humidity and UV Conditions (PRESENTATION)
Power Point presentation: EPA’s Office of Research and Development and Battelle have conducted experimental work to evaluate the efficacy and applicability of several radiological decontamination technologies for deployment in response to a wide-area event, such as a radiologica...
Design, Testing, and Deployment of a Mobile Emergency Water Treatment System (PUBLISHED REPORT)
This mobile treatment technology system in this study is referred to as the Water-On-Wheels (WOW) Cart. The mobile system originally consisted of a pre-filter, an on-site chlorine generator, and a pump attached to a dolly or frame with wheels. The frame also provided space to st...
Disaster Waste Management (WM) Tools - Improving Their Effectiveness While Minimizing Resource Needs (PRESENTATION)
In response to these needs, several EPA programs and regions have developed WM and sustainable materials management (SMM) related decision support and planning tools. These tools support decisions like where to dispose or recycle the waste and debris, where to stage the waste, a...
EPA’s Integrated Rad Remediation Decision Support Tool (IRRD-ST) to Optimize Radiological Cleanup Decisions (PRESENTATION)
As part of its mission to protect human health and the environment, the U.S. Environmental Protection Agency (EPA) conducts characterization efforts to understand the type, extent, and level of contamination resulting from a chemical, biological, or radiological (CBR) incidents. ...
Efficacy and Compatibility of Decontamination Options for Sensitive Equipment-Related Materials Contaminated with Persistent Chemical Warfare Agents (PUBLISHED REPORT)
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...
Evaluation of Environmental Fentanyl Contamination and Sampling Effects for Remediating Affected Areas (PRESENTATION)
Fentanyl contamination is widespread from illegal production and usage in urban settings, like houses, apartments, buildings, and cars. After contamination occurs, the affected areas will need to be remediated so that they can be returned to service within the communities. The pr...
Experimental approaches to inform stormwater modeling during emergency response and recovery- Poster (PRESENTATION)
Following a terrorist attack or natural disaster, contamination could be spread broadly throughout the environment. The intentional or accidental release of chemical, biological, or radiological (CBR) agents is particularly concerning in large cities, where densely populated area...
