This tech brief will summaize the available information on the persistence of biological and radiological agents on wastewater (collection system) infrastructure and decontamination information (if available). It will also summarize data on the fate of radionulcides in wastewater...

Understanding the migration path of pollutants is critical to protecting human and environmental welfare, particularly in population-dense settings with a high fraction of impervious materials that contribute to potentially high pollutant wash off. This research measured the rem...

In support of improving simulated training, EPA is evaluating the use of three-dimensional commercial-off-the-shelf (3D COTS) game engines for facilitating modeling, training, and exercise efforts for CBRN incidents. Today’s 3D COTS game engines rival (if not exceed) the capabili...

The User Guide and corresponding Template Tool are provided to facilitate generation of an outline that can be used to develop sampling and analysis plans (SAPs) in support of exercises, research studies or remediation activities following a contamination incident involving patho...

As part of the response and recovery operations following a wide-area biological contamination incident, such as an aerosol release of Bacillus anthracis, environmental sampling will play a prominent role in response activities. This need for environmental sampling will extend to...

Through an intelligent software wizard, the RRLT helps the user understand what types of equipment might be available to accomplish general and specific recovery mission activities based on environmental and operational constraints. The purpose of the RRLT is to increase the resi...

Presentation to the International Ultraviolet Association on the UV disinfection rserach agaisnt SARS-CoV-2 virus on relevant surfaces

In the event of a chemical, biological, radiological, or nuclear (CBRN) wide-area incident, the U.S. Environmental Protection Agency (EPA) is responsible for clearance, waste disposal processes, and data collection and quality checks to advise decision-making. This research effor...

Although great progress has been made to advance the scientific understanding of oil spills, tools for integrated assessment modeling of the long-term impacts on ecosystems, socioeconomics and human health are lacking. The objective of this study was to develop a conceptual frame...

In this report, sampling and analysis method ranges of recovery efficiency (RE), limit of detections (LOD), and false negative rates (FNR) for environmental matrices and analysis methods will be summarized and used to illustrate their effects on the interpretation of sampling res...

A wide-area release of a persistent biological agent such as Bacillus anthracis (Ba) and subsequent response and recovery activities will likely generate large quantities of waste that will require treatment and disposal. It is likely that most of the waste will be packaged in ba...

The management of response and recovery operations from a biological contamination incident is complicated by the fact that contamination may spread following the incident and subsequent initial extent-of-contamination characterization efforts due to impacts of wind, precipitatio...

Management of waste from biological and radiological incidents is complicated by the fact that decontamination decisions have a profound impact on the characteristics of resulting waste streams. Wide-area biological and radiological incidents could produce massive quantities of w...

Most emergency water treatment systems are large and expensive tractor-trailer mounted systems. They can be complicated to operate and maintain (high pressures and concentrated wastes) given their reliance on reverse osmosis water treatment technology. An emergency water treatmen...

Combined slides from all CESER/HSMMD PIs that conduct research under AnCOR for the APril 27/28 Quarterly meeting with DHS and USCG

The primary objectives of this project research effort were to analyze the potential for application of an aggressive air sampling (AAS) technique for measurement of spores resulting from a dissemination of a biological agent, Bacillus anthracis (Ba), in an indoor environment and...

Bacillus anthracis, the causative agent for anthrax, is a dangerous pathogen to humans and has a history as a bioterrorism agent. While sampling methods have been developed and evaluated for characterizing and clearing contaminated indoor sites, the performance of these sampling ...

The purpose of this study was to determine the impacts of PAA fog and LCHPV on representative indoor materials and electronic equipment. The fogging of PAA solution caused visually observed appearance changes (e.g., discoloration, oxidation, residue) on the copper, low-carbon ste...

Atmospheric dispersion modeling is one tool that can be used for effective emergency preparation or response from hazardous chemical, biological, radiological, nuclear, and explosive (CBRNe) releases, especially in urban areas where population densities are high and wind flow bec...

The phages were inoculated onto six material types (both porous and nonporous), with and without the presence of human whole blood. The inoculated materials were then exposed to either a high or low concentration of HPV, and the phages were recovered from the materials at several...

The purpose of this study was to evaluate the effects of altered environmental conditions on the persistence of Francisella tularensis bacteria and Venezuelan Equine Encephalitis virus, on two material types. Results from this study provide information for inactivation of non-spo...

Francisella tularensis is a fastidious, Gram-negative coccobacillus and the causative agent of tularemia. To access viability yet overcome lengthy incubation periods, a culture-based PCR method was used to detect early growth of the lowest possible number of F. tularensis cells....

This product is an interim data report for an ongoing project. The overall goal of this project is to provide the general public, emergency responders, and healthcare workers with initial information on the effectiveness of selected disinfection/cleaning technologies and commerci...

Recently engineered nanomaterials (ENMs) have been increasingly used to remove contaminants from surface water but also to remediate soil and groundwater contaminated with organic/inorganic pollutants via advanced oxidation and chemical reduction, sorption, complexation, and (co)...

Development of numerical models to predict stormwater-mediated transport of pathogenic spores in the environment depends on an understanding of adhesion forces that dictate detachment after rain events. Zeta potential values were measured for Bacillus globgii and Bacillus thuring...
