The US Environmental Protection Agency&rsquo;s newly released tool, the Equitable Resilience Builder (ERB), guides practitioners through a resilience planning process that provides support for communities in the face of climate change and disasters. The ERB process is specificall...

Dispersion models, which are important tools for efficient routine releases and emergency response preparation scenarios, typically incorporate logarithmic wind speed profiles when simulating flow and downwind dispersion. This may be acceptable for regions with low surface roughn...

Tracking the subsea oil plume during the 2010 Deepwater Horizon Oil Spill (DWH) was conducted using in situ fluorescence via vertical profilers (n=1,157) and discrete sample chemical analyses (n=7,665). During monitoring efforts, discrete samples provided a coarse picture of the ...

Management of waste from radiological incidents is complicated by the fact that decontamination decisions have a profound impact on the characteristics of resulting waste streams. Wide-area radiological incidents could produce massive quantities of waste that might need to be tre...

Photo-induced toxicity of petroleum products and polycyclic aromatic compounds (PACs) is the enhanced toxicity caused by their interaction with ultraviolet radiation and occurs by two distinct mechanisms: photosensitization and photomodification. Laboratory approaches for designi...

This is a presentation for the Energy Exchange Conference in Cincinnati, OH Oct. 25-27.&nbsp; This presentation will discuss premise plumbing infrastructure remediation technologies that could assist home and building owners in removing contaminants immediately following a disast...

Organic contaminants such as benzene can enter drinking water systems through several mechanisms such as oil spills, industrial accidents, and natural disasters. Recently, benzene contamination has been discovered in drinking water systems affected by wildfires in California. Exa...

Two underwater oil detection technologies have been developed: (1) A Remote Environmental Monitoring UnitS (REMUS-600) AUV equipped with fluorescence and backscatter SeaOWL UV-A (Oil-in-Water Locator; Sea-Bird Scientific WET Labs Inc.), holographic imager (HoloCam; SeaScan, Inc),...

Historically, visual observation is an emergency responder’s first ‘tool’ in identifying spilled oil. Optical detection has since expanded to include a myriad of signals from space, aircraft, drone, vessel and submersible platforms that can provide critical information for decisi...

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.

Large-scale disasters have the potential to generate a significant amount of waste. For example, Hurricane Katrina and the Joplin Missouri tornado resulted in 100 million and 1.5 million cubic yards of waste, respectively. Man-made chemical, biological, radiological, or nuclear (...

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...
