Emergency Response Research Milestones
On this page, view by decade:
Since the beginning, our Agency has been grounded in science. EPA's emergency response research strengthens the resiliency of communities in the U.S. Our work provides water utility managers, on-scene coordinators, laboratory technicians, risk assessors, and emergency responders with the tools, methods, technology, and support to prepare for, respond to, and rapidly recover from all environmental disasters. Here are some of our most important research achievements.
2021 - Responders Use New Tool to Meet Cleanup Goals
A large-scale release of a biological or radiological (BR) agent can contaminate a wide area and require significant time and resources for recovery. To assist responders, EPA developed the Trade-Off Tool for Sampling (TOTS), an online resource that can be used to address site-specific objectives, meet clearance goals and avoid exceeding available resources for remediation of the site.
2021 - EPA Framework Supports Efforts to Understand the Impacts of Oil Spills
EPA conducted a study to develop a framework to integrate short-term models for operational oil spill forecasting used for emergency response and immediate cleanup efforts and longer-term models used for damage assessment and strategic planning. The framework can be used to assist decision-makers in seeing the full impact of an oil spill and consider indirect effects.
2021 - EPA Report Provides Information on Getting to Know Communities and Cultures Impacted by Contaminated Sites
EPA published a report that provides a social science-based methodology for learning about key characteristics and constituencies of communities, cultures and affected populations near contaminated sites. It includes steps and information sources to determine who lives near the sites, discusses how cleanup situations might affect which steps, and presents qualitative data management and analysis techniques.
2021 – EPA Provides Information on Cleaning Fentanyl from Responder Gear and Personal Protective Equipment
Illicit fentanyl use that results in the contamination of indoor environments is on the rise. Each incident creates an exposure risk to law enforcement, hazmat operators, and remediation contractors. EPA published a report that provides information on the efficacy of decontamination options for building materials and responder gear/PPE.
2021 – EPA Report Offers Ways to Detect Contaminants in Drinking Water With Sensor Technology
EPA published a report that provides an update to the 2009 report on water quality monitoring sensor technologies that can be used to detect contaminants in a drinking water distribution system. The information can help states and water utilities understand the homeland security benefits of online sensors used for day-to-day operations as well as the long-term maintenance needs and costs.
2021 - EPA Evaluates Electrostatic Sprayers for COVID-19 Disinfectant Application
Researchers evaluated innovative ways to disinfect spaces frequently touched by many people, such as the use of electrostatic sprayers and foggers. The use of these alternative methods has increased substantially with the COVID-19 outbreak. A journal article discussed the methods and results in which several types of electrostatic sprayers and foggers were evaluated for parameters such as spray charge, droplet size, and disinfection efficacy.
2021 - EPA Develops Rapid Test Method to Detect SARS-CoV-2 on Environmental Surface Samples
EPA researchers developed the Rapid Viability-reverse Transcriptase PCR method to quickly assess SARS-CoV-2 survival on real-world surfaces and to understand surface transmission. This new method can support epidemiology investigations and environmental surveillance in healthcare and non-healthcare facilities, and within a community.
2021 - EPA Research Supports Cleaning and Disinfecting of Personal Protective Equipment for Effective Reuse
Researchers evaluated the effectiveness of disinfection/cleaning technologies and commercial off-the-shelf products for specialized and non-specialized personal protective equipment (PPE) items for potential reuse during the COVID-19 pandemic. This information can help responders and front-line workers understand what type of disinfection/cleaning is most effective without the loss of integrity and relieve pressure on the supply chain, which has struggled to keep up with demand for PPE.
2021 - EPA Researchers Evaluate Residual Antimicrobial Coatings
Surfaces contaminated by SARS-CoV-2 that are frequently touched by many different people can pose a risk to public health because of the significant challenge for continuous cleaning and disinfection. Researchers evaluated a number of commercially available products for residual disinfection on surfaces over time and how durable the disinfection ability of the product is with normal use, including routine cleaning and natural weathering.
2020 - After a 50-Year Partnership, EPA Wraps Up Presence on the University of Las Vegas Campus
EPA’s long and rich history on the campus of the University of Las Vegas, Nevada (UNLV) wrapped up on September 30, 2020. The 50-year scientific partnership between EPA and UNLV allowed researchers to develop new science that helped EPA respond to catastrophic national events, including radiation monitoring and cleanup of the Three Mile Island accident in 1979, mapping dust plumes from the collapse of the World Trade Center towers in 2001, and analyzing dispersant agents used for clean-up of the Deepwater Horizon oil spill in 2010.
2018 - EPA Helps the US Coast Guard Analyze the Resiliency of its Ships and Coastal Property
EPA collaborates on a full-scale demonstration and exercise project to prepare for potentially devastating contamination incidents. The project, called Analysis for Coastal Operational Resiliency (AnCOR) is designed to develop and demonstrate capabilities and strategic guidelines to prepare the nation for a wide-area release of a biological agent at US Coast Guard facilities and assets (e.g. ships). This program develops science-based results to support wide-area response and remediation decisions. AnCOR continues through 2022 and includes experiments from the laboratory bench scale through the pilot scale. It will conclude with a large-scale demonstration.
2017 - EPA Develops a Fentanyl Fact Sheet to Protect Emergency Responders
A small amount (~1 mg) of the dangerous opioid fentanyl can kill someone. That is why first responders are concerned about potential exposure while responding to emergencies. EPA researchers and staff worked together to develop the publicly available Fentanyl Fact Sheet. It gives EPA On-Scene Coordinators current information and is also useful for emergency medical technicians, hazmat teams, and law enforcement. In the process of developing the Fentanyl Fact Sheet, EPA experts also identified gaps associated with fentanyl remediation efforts, such as a lack of information on how to decontaminate structures and proper sampling to determine a safe level for re-occupancy. Without this information, fentanyl-contaminated properties are left condemned. EPA researchers are addressing these gaps so that information will be available to responders and can be used to facilitate a remediation strategy.
2017 - EPA’s Water Treatment Cart Helps Puerto Rico Recover from Hurricane Maria
In the aftermath of a disaster, people need access to safe and clean drinking water. EPA and the non-profit cooperative research and development agreement partner, WaterStep, develop an inexpensive and easy to operate water treatment cart featuring granulated activated carbon, ultraviolet disinfection and chlorine disinfection to rapidly treat heavily contaminated water. The Water-On-Wheels cart enables treatment for a wide range of natural and man-made contaminants quickly and effectively. Following Hurricane Maria in Puerto Rico, EPA deploys smaller versions of the water treatment technology to provide safe drinking water to over 200,000 residents.
2016 - EPA Co-leads Underground Transportation Restoration Project
Following a biological incident in a transportation hub such as a subway system, effective remediation of railcars, subway tunnels, and stations would require the use of various approaches to characterize, clean-up, and clear the contaminated area for reentry and reuse. The U.S. Department of Homeland Security initiated the Underground Transport Restoration Project in 2013 to improve the capability of transit systems to recover rapidly from a biological contamination incident. As part of the project, EPA researchers evaluated multiple methodologies for decontaminating subway system and railcars contaminated with anthrax. The study yielded valuable information on the types of materials most difficult to decontaminate and which decontamination chemicals were most effective.
Underground Transportation Restoration Project
2014 - EPA Launches the Water Security Test Bed
Advancing the science of decontaminating pipe systems and safely disposing of high-volumes of contaminated water are high priorities for EPA. Researchers develop the first large-scale water security test bed (WSTB), which is part of a full-scale drinking water distribution system. Researchers use the WSTB to evaluate infrastructure decontamination technologies previously tested by the EPA at the bench- and pilot-scale. The test bed allows for injection of contaminants that cannot be tested in municipal water facilities. EPA researchers can now evaluate decontamination methodologies to determine which are best suited for use by water utilities. The WSTB facility also enables testing of water treatment technologies for the effective management of the water that is discharged from the contaminated pipeline into a 28,000-gallon lagoon. In addition, decontamination methods for building plumbing and household appliances can be evaluated in an adjacent building.
2014 - EPA Provides Technical Support for Waste Contaminated with Ebola Virus
During the Ebola outbreak in 2014, EPA experts worked closely with the Centers for Disease and Prevention to publish recommendations on disinfectants for use against the Ebola virus because none were previously registered under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). Following the outbreak, EPA recognized the need for standing guidance on addressing emerging pathogens so that these incidents are not handled in an ad hoc manner. The scientific approach that was used to address Ebola virus was translated into new guidance for FIFRA registration of antimicrobial disinfectants targeting emerging pathogens based upon existing efficacy data on analogous pathogens.
2013 - The Bio-response Operational Testing and Evaluation Project Tests and Evaluates Decontamination Techniques
The Bio-response Operational Testing and Evaluation (BOTE) project is a multi-agency effort that tested and evaluated decontamination techniques for a biological incident. BOTE researchers evaluated three technologies for decontaminating a building by simulating an anthrax attack using nonpathogenic surrogate to Bacillus anthracis spores, which cause anthrax infection. Researchers collected data to compare the success and cost of the decontamination methods. The results have been used to help guide further decontamination research to ensure effective response to biological attacks.
2011 - EPA Supports the Cleanup of the Fukushima Daiichi Nuclear Accident
The release of radiological contamination at Japan’s Fukushima Daiichi nuclear plant becomes the largest nuclear disaster since Chernobyl in 1986. Japan requests help through its diplomatic contacts. The US Embassy Science Fellow Program provides a team of radiological decontamination experts, including one member from EPA. The team draws upon their experience with large-scale projects at Department of Energy and EPA to provide information, lessons learned, and suggestions of technologies to benefit the remediation efforts in Japan.
2011- EPA’s Methods Help the Fukushima Daiichi Emergency Responders
EPA’s Selected Analytical Methods (SAM) is a list of analytical methods that scientists use to analyze environmental samples in times of national emergency. When Fukushima’s Daiichi nuclear power plant releases radiological contamination after an earthquake and tsunami, EPA provides SAM data for two radioactive elements, cesium and iodine, to help emergency responders analyze samples taken from the nuclear power plant.
2010 - Researchers Use New Tool to Measure Contamination After Mock Dirty Bomb Attack
EPA researchers demonstrate their new Waste Estimation Support Tool (WEST) during a simulated "dirty bomb" attack. WEST assists the researchers with estimating the potential volume and radioactivity levels of waste generated by a radiological incident and subsequent decontamination efforts at a terrorist attack. The exercise, called Liberty RadEx, is the largest drill of its kind sponsored by EPA to test the country’s capability to clean up and help communities recover from a dirty bomb attack. The Pennsylvania Department of Environmental Protection and City of Philadelphia co-sponsored the five-day homeland security exercise in Philadelphia. Over 700 people from federal, state, and local agencies and private companies take part in the drill.
2009 - Researchers Use Ultrafiltration Device to Detect Microorganisms in Drinking Water
Moving and handling large volumes of potentially contaminated water is a safety concern for transportation and laboratory personnel and the public. To address these concerns, EPA researchers, in partnership with the Department of Energy’s Idaho National Laboratory, develop a rugged and automated field deployable sample concentration (ultrafiltration) device. The device can concentrate the microbes contained in a 26-gallon sample into a sample of fewer than 16 ounces, often in less than one hour. The smaller, concentrated sample is safer to transport to a lab.
2007 - EPA Releases EPANET Multi-Species Extension Software to Protect Water Systems
The original EPANET is a popular software program used to model hydraulic and water quality behavior of drinking water distribution systems. Its water quality component was limited to tracking the transport and fate of just a single chemical species, such as chlorine. The new EPANET-Multi-Species Extension (MSX) allows users to model any system of multiple, interacting chemical species. EPANET-MSX and EPA's other homeland security support tools reduce vulnerabilities in drinking water distribution systems in several ways. They prevent and better prepare water systems for terrorist attacks, minimize public health impacts and infrastructure damage, and enhance recovery efforts from contamination incidents.
2006 - Ann Arbor Uses EPA’s Toolkit to Detect Contamination in Drinking Water
The Threat Ensemble Vulnerability Assessment and Sensor Placement Optimization Toolkit (TEVA-SPOT) enables water utilities to optimize the locations of water quality sensors to improve detection of contamination. The City of Ann Arbor used TEVA-SPOT to find the best set of sensor locations within their drinking water distribution system to minimize average public health effects that would result from release of a chemical contaminant or biological agent. Many water utilities continue to use TEVA-SPOT to detect contamination.
2005 - EPA Researchers Deploy New Tool for Hurricane Katrina Response
Hurricane Katrina generates a tremendous amount of waste and causes catastrophic damage in Florida and Louisiana. EPA researchers use the Incident Waste Assessment and Tonnage Estimator (I-WASTE) tool they developed to help make decisions on disposal of waste during the cleanup. I-WASTE helps to organize large amounts of information related to managing waste resulting from incidents of national significance such as contaminated buildings and natural disasters. It provides a waste volume estimator as well as information on shipping and disposal facilities.
2005 - EPA Supports Anthrax Cleanup with Laboratory Data
A US Department of Defense laboratory inadvertently sends samples of live anthrax spores to many local and state labs. Many of these labs are not equipped or approved to receive such hazardous samples. Further, the shipments have potentially been occurring for many years and staff have been handling these samples in labs unequipped for the hazard. The Centers for Disease Control and Prevention activates its Emergency Operations Center and requests that experts from EPA join their staff to provide guidance on decontamination. Acceptable decontamination options are based largely on EPA laboratory test data. A total of 69 laboratories located in 19 states and six countries are ultimately affected. All of the labs are cleaned up quickly and effectively with EPA's guidance and technical support, avoiding the potential of serious illness and death.
2005 - EPA Hosts the First International Decontamination Research Conference
The International Decontamination Research and Development Conference brings together experts from around the world to share best practices, and research findings, and to discuss ongoing research needs. The conference continues to cover the decontamination processes and technologies, cutting edge research and development, and lessons learned concerning biological, chemical and radiological contamination.
2004 - EPA Releases Methods to Analyze Samples During Homeland Security Events
In the aftermath of the terrorist attacks of Sept. 11, 2001, EPA identifies the need to have a list of pre-evaluated analytical methods to be used by all laboratories when analyzing homeland security incident samples. Having consistent methods reduces confusion, permits sharing of sample load among laboratories, improves data comparability, simplifies the task of outsourcing analytical support to commercial laboratories, and improves validating results, analyzing data and making decisions. To meet this need, EPA publishes The Selected Analytical Methods manual and website to describe methodologies that EPA and its contractors can employ to analyze environmental samples in times of national emergency.
2004 - EPA Founds the National Homeland Security Research Center
Following the terrorist events of Sept. 11, 2001, EPA’s mission expands beyond safeguarding the natural environment (i.e., air, water, and land) from traditional sources of pollution. In 2004, EPA forms the National Homeland Security Research Center to conduct research that answers scientific questions to support homeland security. EPA's Homeland Security Research Program continues to provide science and technology needed to effectively respond to, and recover from, natural or manmade disasters.
2001 - EPA Supports Fumigation of Anthrax at a Postal Facility
A letter containing anthrax spores contaminates the 14 million square foot Brentwood post office in Washington, DC. Two postal employees die from exposure to the anthrax. Despite early cleansing operations that focus on the specific areas of contamination, anthrax is found to have spread throughout the building. The US Postal Service (USPS) decides to fumigate the entire building to inactivate the remaining spores. EPA researchers oversee and provide advice on the fumigation including reviewing numerous documents on tests and trials of different components of the scrubbing system to ensure the fumigation is successful and does not result in releases that could be harmful to the public. EPA’s work allows the USPS to obtain Federal Insecticide, Fungicide, and Rodenticide Act Crisis Exemptions needed to perform the fumigation.
2001 - EPA Develops a Method to Find Asbestos-Contaminated Dust from the World Trade Center
The collapse of the World Trade Center (WTC) towers on Sept. 11, 2001 covers much of New York City in dust and rubble that includes asbestos. The dust also penetrates buildings. Public health officials raise concerns about the health effects from exposure to the dust. EPA and their partners at the United States Geological Survey develop an analytical method to distinguish WTC dust from dust from other sources. This helps scientists supporting the World Trade Center Expert Technical Review Panel determine the extent of contamination from WTC dust.
