2018 EPA International Decontamination Research and Development Conference (SUMMARY)
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...
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...
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...
Control of Emissions from Combustion of Cesium-Contaminated Biomass via Sorbent Injection (PRESENTATION)
In the aftermath of a wide-area radiological contamination incident, there is the potential for the generation of significant quantities of contaminated biomass waste. For example, the 2011 nuclear power plant accident at the Fukushima Daiichi plant in Japan resulted in an estima...
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. ...
Evaluating Solid Sorbents for Recycling Wash Waters Containing Strontium and Calcium (JOURNAL)
A radiological release from a radiological dispersal device (RDD) or an improvised nuclear device (IND) has the potential to contaminate a vast area both near the dispersal epicenter and via atmospheric deposition of small particles containing the more volatile contaminants. Rapi...
Evaluation of Low-Tech Outdoor Decontamination Methods Following Wide Area Radiological/Nuclear Incidents (PUBLISHED REPORT)
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, ...
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...
Laboratory Analytical Waste Management and Disposal Information Document Companion to Selected Analytical Methods for Environmental Remediation and Recovery (SAM) (PUBLISHED REPORT)
This document addresses management of laboratory analytical waste unique to remediation activities following a homeland security incident when SAM methods would be applied, and assumes that specific environmental sample types (i.e., water, soil, surfaces wipes, air particulates a...
Logistics Modeling of a Wide Area Decontamination Operation using Wash Down Techniques (PRESENTATION)
This presentation discusses is a framework to evaluate the timeline of available decontamination strategies based on resource availability and operating limitations.
Management and Disposal of Vehicles Following a Wide-Area Incident (PRESENTATION)
Large-scale natural disasters have the potential to generate a significant amount of waste. Man-made chemical, biological, radiological and nuclear (CBRN) incidents, either by way of terrorism, war, or accident, have the potential to generate as much or more waste. Furthermore, f...
Potential Local to Regional Scale Impacts from Wildfire Re-emission of Hypothetical Radiological Contamination Incidents (PRESENTATION)
An Eulerian 3D photochemical transport model was used to estimate potential ambient impacts of Cesium-137 re-emission due to wildfire following hypothetical radiological release scenarios followed by subsequent contamination of forested areas in Denver, CO and Los Angeles, CA. La...
