This technical brief reviews the bench-, pilot-, and field-scale decontamination research conducted by EPA under the Underground Transport Restoration (UTR) project. This summarizes the findings most applicable for operational use in decontamination methods for railcar and relate...

This report summarizes the results of biological decontamination experiments performed at the WSTB focused on removing Bacillus globigii spores adhered to the inner surface of the 8-inch water pipe. B. globigii spores are a non-pathogenic surrogate for B. anthracis, which is the...

Report on the decontamination efficacy of low levels of hydrogen peroxide vapor (HPV) was evaluated on common building materials (glass, bare pine wood, carpet, painted wallboard paper, unpainted concrete, and ceiling tile) contaminated with Ba spores.

A large-scale outdoor biological disaster requires a better understanding of how rainfall and water-based decontamination measures would transport contaminants. Over the last few years, the United States Environmental Protection Agency’s (EPA’s) Homeland Security Research Program...

Slide Presentation -Francisella tularensis is a Category One select agent and causes Tularemia infection. It can survive for a long time in water. The RV-PCR method will help rapid detection during an intentional (bioterrorism) or accidental contamination of drinking water system...

This project focused on identifying the bacteria that are the potential sources of positive total coliform assays, on locating potential hotspots for bacterial colonization within aircraft plumbing materials, and on investigating the effectiveness of the airline industry’s curren...

This technical brief reports the results of two recent studies that aimed to increase our understanding and capabilities with regards to decontamination of outdoor areas following a biological incident. These data help responders develop remediation plans following outdoor contam...

This report by the U.S. Environmental Protection Agency’s (EPA’s) Homeland Security Research Program (HSRP) strives to provide expertise and products that can be widely used to prevent, prepare for, and recover from public health and environmental emergencies arising from terrori...

This report chronicles the study undertaken to evaluate the decontamination efficacy of diperadipic acid, under application conditions that were found to be effective for pH-adjusted bleach (a common sporicidal liquid). The results showed that diperadipic acid demonstrated >6 Lo...

Personnel decontamination is an integral part of any emergency response. This report discusses a decontamination project that evaluated the decontamination efficacy and physical migration (transport) of Bacillus spores and operational efficiency of two types of sprayer technologi...

This report focus for fixed site surface decontamination and cleanup, two distinct options among liquid disinfectants include pH-adjusted bleach (pAB) and Spor-Klenz® (S-K; per-acetic/peroxide formulations). Efficacy of these two sterilants in lab-scale studies has been well-docu...

In both developing and industrialized nations, a growing number of contaminants are entering water supplies from human activities. In addition, the events of September 11, 2001, in the United States have raised concerns about the potential for intentional contamination of water s...

Historically, street sweeping primarily has been conducted to remove the regular buildup of litter and trash along urban streets. Recent developments in sweeper technology, such as regenerative sweepers and “dustless sweepers”, enable municipalities and transportation departments...

Report—Exposure estimates were performed to rank the various livestock carcass management options relative to one another for a hypothetical site and mortality scenario from a potential biological incident. Assessment included an ordinal scale ranking (ranking of individual condi...

Report--Provides information and a screening tool to perform an exposure assessment for emerging pathogens in wastewater systems

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 ...

Poster -To elucidate the prevalence of naturally occurring B.anthracis, USEPA NHSRC scientists teamed with scientists from the USGS Mineral Resources Program scientist to analyze soil samples from 4,770 sites as part of the North American Soil Geochemical Landscapes Project. USEP...

Poster - EPA’s Homeland Security Research Program is collaborating both across the agency (with several regions and offices) and outside the agency to develop an online tool, the MicroSAP, which aims to assist users with development of Sampling and Analysis Plans (SAPs). The tool...

Report

In the event of a release of a biological agent in an urban area, a wide range of surfaces may be contaminated, including indoor surfaces in homes and businesses. This research was conducted to identify and evaluate low-technology (low-tech) remediation methods that could be used...

Report

Report: An informational companion to the MicroSAP tool which includes considerations for sampling, analysis, and data interpretation that users might include in a sampling and analysis plan being developed for a microbiological contamination incident.
