A probability-based sampling design can be used to create statistically defensible sampling plans. However, these plans may have sampling collection and/or processing demands that exceed allotted resources. Targeted sampling designs, also referred to as judgmental sampling, use p...

This technical summary report provides a review of the U.S. EPA Office of Research and Development&rsquo;s (ORD) laboratory studies that evaluated the efficacy of decontamination techniques to neutralize ricin on a variety of different surfaces. The tests referenced in this summa...

Global positioning systems (GPS) provide users with positioning, navigation, and timing services. However, this resource is limited when it comes to gathering information and guidance for interior spaces: GPS signals communicate with satellites and do not move easily through soli...

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

Battelle and EPA evaluated the effectiveness of UAV platforms to perform volumetric measurements of various types of debris (e.g., biomass such as fallen vegetation, stacks of building material, and other debris) using &nbsp;lidar and structure from motion (SfM) photogrammetry. T...

Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that have been in use since the 1940s in a wide array of consumer products. PFAS are persistent in the environment and bioaccumulate. Thermal treatment methods are currently applied to a variety of mater...

The purpose of this work is to provide data and information to refine existing guidance about how to flush per- and polyfluoroalkyl substances (PFAS) from firefighting systems, specifically hangar systems and Aircraft Rescue and Firefighting (ARFF) vehicles. It is relevant to the...

Radioactive fallout could have debilitating effects on drinking water and wastewater systems. At least some drinking water system operators have plans to mitigate the effects of a contaminated water source, but most, if not all, wastewater operators have no such plans.&nbsp; Both...

Legionella pneumophila (Lp) is an opportunistic drinking water pathogen that can cause infections through the inhalation of Lp-containing aerosols. Lp can occur in premise plumbing systems as these systems often have low disinfection residual, high surface area-to-volume ratios, ...

The threat of cascading and compounding disasters in low-income and underrepresented communities with hazardous and polluting sites makes urgent the need to build resilience. The Equitable Resilience Builder (ERB) is a new tool designed for situations where capacity and resources...

Report on the Wide Area Demonstration (WAD) under the Analysis for Coastal Operational Resiliency (AnCOR) project. The AnCOR WAD was conducted from May 2 through May 27, 2022. The test venue was located at Fort A.P. Hill (FAPH), Bowling Green, VA. All work will was conducted at F...

Drinking water storage tanks serve several important functions, which include but are not limited to providing an adequate water supply in the case of firefighting emergencies, power outages, water main breaks, or other system failures. The water level elevation in storage tanks ...

The purpose of this research was to determine the viability of installing low-cost storm sewer retrofit devices in multiple locations within an urban watershed.  A major component of this was the necessity for designing, fabricating, and operation of such retrofits which are not ...

This is a power point presentation that summarizes the potential for phototoxicity of crude and refined oils. The presentation will cover the phototoxic components of oil, mechanisms of petroleum phototoxicity, and the environmental and biological modulation of phototoxicity.

The U.S. Environmental Protection Agency, Office of Research and Development, Homeland Security Research Program (HSRP) aims to increase United States&rsquo; capabilities to prepare for and respond to releases of oil and hazardous substances into the environment. HSRP&rsquo;s inn...

The U.S. EPA&rsquo;s Homeland Security Research Program (HSRP) is charged with protecting human health and the environment from accidental and intentional releases of toxic chemicals and other threat agents. Such chemical agents include Fourth Generation Agents (FGAs), which repr...

The presentation provides the updated information on the progress of Fukushima environmental remediation from the 2011 nuclear power plant accident.

Systems engineering can encapsulate many areas of design and production.&nbsp; A prudent course is to consider the environmental effects in design, construction, operation, product manufacturing and use, and end of life.&nbsp; To consider these effects requires information about ...

The compatibility of dense non-aqueous phase liquids (DNAPLs), trichloroethylene (TCE), methylene chloride (MC), and creosote with commercially available sodium bentonite pellets was evaluated using stainless steel, double-ring, falling-head permeameters. The Hydraulic conductiv...

The Pawcatuck River flows through Westerly, Rhode Island before discharging into Little Narragansett Bay. The Pawcatuck River has a long history of pollution associated with textile and dye manufacturing due to historic mill operations along the riverbank. Operations at the Bradf...

This report highlights the importance of effective data management in disaster response, specifically focusing on environmental sampling. In today's data-driven world, data management is crucial for decision-making, coordination, and systems thinking in disaster scenarios. Effici...

This report summarizes the results of infrastructure decontamination experiments performed at the WSTB.&nbsp; These experiments focused on simulating contamination of drinking water distribution pipes with a commonly available insecticide formulation containing malathion.&nbsp; M...

Waste is produced at all stages of the response and recovery (including decontamination) following a biological contamination incident. Types of materials that generate a significant proportion of the waste at every stage of the response include personal protective equipment (PPE...

Wildfire risks and losses have increased over the last 100 years, associated with population expansion, land use and management practices, and global climate change. While there have been extensive efforts at modeling the probability and severity of wildfires, there have been few...

The Analysis for Coastal Operational Resiliency (AnCOR) program is an interagency collaboration between the U.S. Environmental Protection Agency (EPA), the Department of Homeland Security (DHS), and the United States Coast Guard (USCG). The overall purpose of this multiagency pro...
