There are currently outbreaks of African Swine Fever Virus (ASFv) in Asia and Europe. ASFv has recently been confirmed in The Dominican Republic, the first ASFv outbreak in the Western Hemisphere in 80 years. ASFv is a hemorrhagic fever virus which only affects pigs. The U.S. Dep...

This paper discusses development of a computer-based tool that allows practitioners to leverage the Analytical Hierarchy Process (AHP), a well-established method of MCDA, to select remediation technologies based on their effectiveness and their compatibility with the practitioner...

States and localities are looking for ways to integrate climate resilience and environmental justice into how they prepare, respond, mitigate, and recover from disasters. These efforts require effective and inclusive engagement with many broad constituencies. The research present...

Chemical dispersant formulations typically provide maximum oil dispersion in waters between 30-40 ppt (parts per thousand) salt content, which encompasses typical ocean salinity (~34 ppt). As a result, most laboratory studies of oil dispersion effectiveness (DE) are conducted at ...

Introduction:  Many aqueous film forming foam (AFFF) delivery systems in aircraft hangars and firefighting vehicles may require thorough cleaning to avoid ongoing environmental impacts from residual per- and polyfluoroalkyl substances (PFAS) within those systems. Though replaceme...

&nbsp;In all, this presentation will familiarize the audience on the decision support tool&rsquo;s overall versatility and breadth to which it can support objectives, strategies, and tactics not only for nuclear and radiological releases, but also chemical and biological threat a...

A rapid analytical method for detection of infectious (live) SARS-CoV-2 in environmental surface samples (e.g., swabs) was needed to better understand the surface transmission of this virus and to support environmental epidemiological investigations. To address this need, a proof...

Presenataion includes discussion of CDC/EPA guidance on cleaning and disinfeciton of surfaces, research results on cleanign and disinfecton efficacy, research on antimicrobial coatings, and EPA FIFRA guidance.

Presentation on results for cleaning and disinfection methods against SARS-CoV-2.

Controlled resuspension experiments were performed to understand how the rate of Bacillus spore resuspension changes over time and under the influence of variable meteorological conditions. Two coupon types (concrete and asphalt, 66 of each type) representing surfaces typically f...

The COVID-19 pandemic has highlighted the role that airborne transmission can play in the spread of disease. Consequently, there has been an increasing focus on technologies that claim to reduce or eliminate aerosolized pathogens in indoor occupied spaces. There are many differen...

Evaluation of surface sampling methods for USCG assets, following a biological contamination incident.&nbsp;

To this end, this study partnered with a world-wide supplier of street sweepers to mimic the operation of their sweeper at the laboratory scale in order to study its capabilities and evaluate its efficacy against contaminated dust and dissolved forms of radioactive contamination....

Management of waste from wide-area radiological incidents will be complicated by several major issues: 1) the potentially enormous quantities of solid and aqueous waste, lightly contaminated with one or more radionuclides, that will need to be properly managed; 2) the profound im...

Remediation and removal actions, otherwise known as &ldquo;cleanup,&rdquo; at contaminated sites takes place in diverse socio-cultural contexts. It may involve working with communities that have different ethnic identities, languages, histories, values, and ideologies. Research h...

As salt marshes migrate upland due to sea level rise, they will encounter many kinds of coastal development and infrastructure. Hazardous and contaminated sites (HCSs) -- facilities and infrastructure that store, use, or release toxic substances -- are particularly concerning obs...

 The objective of this research is to gain a better understanding of the various DWDM decision points, actors, and social conflicts. By mapping these variables across disaster types, community types, and waste material types, we will 1) add to social science theory regarding deci...

This is a presentation on social science research on disaster waste and debris management decision-making.

Aims: To obtain quantitative efficacy data of two ultraviolet light (UVC) technologies for surface inactivation of Bacillus anthracis Ames and Bacillus atrophaeus spores. Methods and Results: Spores were deposited onto test coupons and controls of four different materials, via l...

The primary objectives of this project were to evaluate the disinfection performance, reliability, and energy use requirements of two small-scale UV-C LED water disinfection units (e.g., 10 gallons per minute (gpm) rated sizes) for a variety of test conditions. Test conditions in...

Urban areas create complex wind flow patterns that can affect contaminant dispersion downwind of a harmful release. This can result in challenging&nbsp;situations for local officials or emergency responders who must plan for or remediate infrastructure after major chemical, biolo...

Drinking water systems in Santa Rosa and Paradise, California both experienced persistent benzene contamination following drinking water distribution system damage from wildfires. Uptake and release of benzene by polyethylene materials, such as polyethylene pipes, in the water sy...

The purpose of this experiment is to develop a system of deployable sensor stations that will remotely record various water quantity parameters and report these values back to a central server. All data collected was transmitted to the EPA&rsquo;s data collection and viewing serv...
