Effective sampling of SARS-CoV-2 is crucial for monitoring disinfection efficacy and effective environmental surveillance. This study evaluated sampling efficiency and limits of detection (LOD) of swab and stick sponge sampling methods for recovering infectious SARS-CoV-2 and vir...

RADAR is becoming an integral to HSRPs science and information sharing; therefore, the system must continue to address and expand the needs of our researchers and stakeholders. The updates proposed under this iteration would include the ability to simplify data upload and sharing...

Large-scale biological contamination incidents impacting indoor, outdoor, and underground areas will require extensive time, money, and resources to successfully decontaminate prior to re-occupancy. The ability to estimate the cost of decontaminating affected areas following such...

The COVID-19 pandemic has accelerated the need for proven effective surface antimicrobials, particularly those which offer prolonged protection through longer-term residual activity. There are many products registered by EPA as microbiostatic agents that inhibit the growth of odo...

Efficacy of cleaning methods against SARS-CoV-2 suspended in either 5% soil load (SARS-soil) or simulated saliva (SARS-SS) was evaluated immediately (hydrated virus, T0) or 2 hours post-contamination (dried virus, T2). Hard water dampened wiping (DW) of surfaces, resulted in 1.77...

Determining the effectiveness of new and commercially available disinfectants against SARS-CoV-2 or other viruses requires the ability to quantify recovered infectious virus in cell culture assays (Tissue Culture Infectious Dose 50% [TCID50]). However, the active ingredients in d...

The Remediation Data Repository (RADAR) is a searchable database for accessing multi-hazard research and operational data conducted by the U.S. EPA and other federal and international partners. The tool provides a central repository (i.e., database) that stores up-to-date data de...

Effective characterization of biothreat agents is a critical component of emergency response operations.  In the face of emerging pandemic threats, determining the most effective sampling methods is crucial to developing a common approach to monitoring disinfection efficacy and o...

Presentation slides include the status and progress of waste management for Fukushima Offsite Remediation. The presentation covers offsite contamination and remediation efforts and decontamination approaches by category. Waste Management is also discussed, including approach...

The EPA-approved disinfectant list features multiple products for use on high-touch surface materials, however the majority of these are registered for use only on non-porous materials.  Many high-touch surfaces fall between non-porous and porous materials. The current study...

The ability to implement full-scale disaster response exercises with minimal resources and maximum control and realism is of great interest to the U.S. Environmental Protection Agency (EPA) and the emergency response community. Virtual Reality (VR) holds great promise for providi...

Aims: This study aimed to provide operationally relevant SARS-CoV-2 surface disinfection efficacy information. Methods and Results: Disinfectants were evaluated against SARS-CoV-2 on material coupons and were tested using Spray (no-touch with contact time) and Spray & Wipe (wipe...

This presentation will examine how serious games are being used to enhance the US Environmental Protection Agency’s (US EPA’s) emergency response mission, by improving the ability of the emergency response community to quickly and effectively respond to a range of env...

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...

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...

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

Rapid decontamination following a biological terror incident is paramount for the return of a city’s operations and economy to normalcy. An outdoor urban biological agent incident may require remediation of thousands of vehicles. In this research, the utilization of widely availa...

This study examines the current literature on aerial photography, remote sensing, and ground-based sensor use for estimating waste and debris volume. While there is a growing body of research in this area, the application of Unmanned Aerial Systems (UAS) remote sensing in post-di...

This report summarizes novel air sampling research conducted for the multi-agency Analysis for Coastal Operational Resiliency (AnCOR) program which sought to develop and demonstrate capabilities and strategic guidelines to prepare the US for a wide-area release of a biological ag...

Introducing HSRP tools to support emergency response and some examples of tools for wildfire response at the Lab Enterprise Showcase organized by OSAPE

The Integrated Radiological Remediation Decision Support Tool (IRR-DST) was developed to help decision makers better understand potential options for decontamination and the consequences those options may have on remediation efforts (i.e., systems approach). The IRR-DST...

March 11, 2021, marked the 10-year anniversary of the accident at the Fukushima Daiichi Nuclear Power Plant in Japan which was caused by an initial earthquake and subsequent tsunami. This was the most significant accident at a nuclear power plant since the Chernobyl disaster...

Recovery is profoundly impacted by waste management issues and the strategies selected to manage them. The quantification, segregation, transportation, and storage of waste can be an arduous and costly undertaking. Furthermore, these processes are intricately linked with the deci...

The objective of this study was to assess the efficacy of selected commercially available decontaminant products and cleaning methods to disinfect coronaviruses from surfaces. Specifically, List N products that are effective on hard, non-porous materials were evaluated on challen...

Transport of contaminants from roadways to the environment is well known, although studies of technologies for preventing and managing this appear infrequently in the literature. This paper reviews technologies studied for radiological contaminants. In addition to nuclear facilit...
