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...

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...

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...

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...

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...

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...

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...

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

Report

The report is intended to be applicable to consequence management activities that EPA will be involved with and will require waste characterization. This best practices document is intended to be general and all-hazards in nature, applicable to a multitude of settings, and to pro...

Ricin is a highly-toxic compound derived from castor plant beans. Several incidents involving contamination of structures due to ricin production or dissemination have occurred in recent years. The goal of this study was to determine whether ricin bioactivity could be attenuated ...

This journal article examines EPANET, which is widely employed to simulate water quality in water distribution systems. However, the time-driven simulation approach used to determine concentrations of water-quality constituents provides accurate results, in general, only for smal...

If a terrorist event or natural disaster causes a wide area of land to be contaminated with chemical, biological, or radiological particulates, emergency responders need a rapid way to determine where to sample and decontaminate prior to clearing the area. A comprehensive stormwa...

This report is on the development of a wet-vacuum method to sample medium to large areas for chemicals. The purpose of this project was to provide responding agencies with information on the effectiveness of a wet-vacuum sampling approach for the collection of toxic industrial ch...
