This technical summary report provides a review of the U.S. EPA Office of Research and Development’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...

This subproduct contains text and pictures for an update/extension of the EPA Emergency Response Research's Analysis for Coastal Operational Resiliency (AnCOR) webpage (https://www.epa.gov/emergency-response-research/analysis-coastal-operational-resiliency). It describes the wide...

An intentional and nefarious attack or unintentional release of a chemical warfare agent (CWA) is expected to trigger a significant effort to clean up a contaminated area. Such effort becomes more complex when considering the permeability of common indoor building materials to so...

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...

The timely decontamination of high-density urban areas is critical in the face of a terror event involving radioactive cesium (Cs), which has a 30- year half-life with an energetic 662 keV gamma ray released during decay. This technical brief is intended for local, state and fede...

The delivery of safe, potable water to communities is the primary objective of drinking water utilities. However, the quality of the water can deteriorate as it is transported from the treatment plant through the distribution system to the customers due to interactions with the p...

EPA ORD was awarded a funds-in multi year CRADA with the Canadian Government.  The CRADA is entitled Oil Spill Alternative Response Measures: Toxicity and Biodegradation of Treated Petroleum Oils. This is the Final Summary Report of ORD efforts. The Canadian government requires a...

This brief provides operating information based on reviewed field experience [1] and laboratory experiments [2-5]. While it discusses general safety, this technical brief does not discuss the safe operation of pressurized sprayer equipment to avoid physical hazards which are typi...

This report summarizes efforts to detect contamination from rainfall events using online water quality sensors. Stormwater has long been an area of concern when it comes to contaminant monitoring and potential remediation. Combined Sewer overflow (CSO) systems can collect rainwat...

The SCID is a companion document to the SAM document and will need to be updated to match the SAM 2022 document. Revisions continue from STRAP3. Supports ESAM.

EPA’s Homeland Security Research Program (HSRP) within the Office of Research and Development conducts research to aid in the response and recovery from radiological disasters. EPA is leading stormwater modeling studies that investigate how to simulate transport of radiolog...

This summary outlines the current progress US EPA’s Homeland Security Research Program (HSRP) has made through development of scientific products that support capabilities for non-spore-forming biological incident response. These products are meant to advance the body of sc...

Drinking water utilities face multiple challenges, including aging infrastructure, water quality concerns, pipe breaks, natural disasters, environmental emergencies, and terrorist attacks. All of these have the potential to disrupt service to customers and damage critical infrast...

The goal of this project was to streamline capabilities and identify improved data management tools to better fit the needs of the Department of Homeland Security (DHS), USCG, and EPA responders following a wide-area incident. This was accomplished by evaluating the current state...

This technical brief is a summary of US EPA research publications providing input to solving the technical challenges involved with remediating a large urban area following a contamination incident involving spores of B. anthracis, the causative biological agent for anthrax disea...

This summary outlines the Homeland Security Research Program (HS) Strategic Research Action Plan for the fiscal years 2023-2026. The StRAPs are designed to guide an ambitious research portfolio that delivers the science and engineering solutions the Agency needs to meet its goals...

Although SARS-CoV-2 is primarily an airborne risk, the COVID-19 pandemic also highlighted the need for self-disinfection surfaces that could withstand the demand of high occupant densities characteristic of public transportation systems. The aim of this study was to evaluate the ...

The spread of radiological contamination from rainfall events is well documented from both the Chernobyl and Fukushima nuclear disasters. However, the inclusion of stormwater modeling into local, state, and federal response planning and response is limited. The goal and purpose o...

The U.S. Environmental Protection Agency’s (EPA’s) Homeland Security Research Program (HSRP) conducts research to detect, respond to, and recover from the impacts of terrorist attacks, accidental contamination and natural disasters on the nation's water and wastewater infrastruct...

Data from soil decontamination testing with Burkholderia pseudomallei

This technical brief provides decision makers with a practical summary of recent US EPA scientific information and data related to the technical challenges involved with remediating a fentanyl-contaminated indoor site. The research topics included in this summary are indoor build...

This website update provides a summary of efficacy testing with the Knorr 3-Stage Air Filtration and Purification System in a large aerosol test chamber with a recirculating HVAC system. The unit's efficacy was evaluated against aerosolized MS2 (a bacteriophage).

The U.S. Environmental Protections Agency (EPA) is responsible for responding to environmental contamination incidents that affect human health and the environment. These emergency response efforts will require sampling of a contaminated area until remediation is complete. Sampli...

Managing the response to urban radiological terrorism requires advanced planning and rapid response to minimize health risks to residents and mitigate long-term impacts to municipal infrastructure and the environment.  A radiologic dispersal device can result in a widespread...

This report summarizes a research study on detection of contamination in source waters using on-line water quality sensors.  In this study, source water is untreated water from lakes or rivers.  This water will be treated to make potable drinking water.  Should an ...
