A Review of the Resuspension of Radioactively Contaminated Particles by Vehicle and Pedestrian Traffic – Current Theory, Practice, Gaps, and Needs
(JOURNAL) [Published : Apr 15, 2024]
The resuspension of radioactively contaminated particles in a built environment, such as from urban surfaces like foliage, building exteriors, and roadways, is described empirically by current plume and dosimetry models used for hazard assessment and long-term risk purposes. When...
A Sensitivity Analysis on Parameters Related to Remediation Efforts Following a Wide-Area Biological Incident
(PUBLISHED REPORT) [Published : Sep 01, 2024]
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...

An overview of traditional emergency water treatment approaches includeing bulk water commercial and military systems and home Point-of-Use/Point-of-Entry systems is provided.  Additional information outlining recent EPA research on mobile emergency water treatment technolog...
Case Studies: Estimation of Waste and Debris Following a Radiological Incident
(PUBLISHED REPORT) [Published : Apr 01, 2024]
Waste and debris management presents considerable challenges during any large-scale disaster; additional challenges will exist during a wide-area radiological, or nuclear (CBRN) incident. In the context of a CBRN incident, waste refers to all materials generated as a result of an...
Comparison of liquid and filter sampling techniques for recovery of Bacillus spores and Escherichia coli from environmental water
(JOURNAL) [Published : Nov 15, 2024]
Historically, detecting water contamination has involved collecting and directly analyzing liquid samples, but recent advances in filter sampling methods offer numerous potential advantages. Emerging technologies, including environmental DNA (eDNA) samplers, could be used for rem...
Degradation of Immediate Precursors of Fentanyl and Fentalogs
(JOURNAL) [Published : Jul 01, 2024]
Remediation of clandestine laboratory and processing operations for fentanyl and its analogs (i.e., fentalogs) may involve application of oxidants, most commonly household hypochlorite bleach, to chemically degrade the fentanyl to enable disposition of the site. While the chemica...
Effects of aging of radioactive fallout on timely decontamination of concrete using low and mild pressure washing
(JOURNAL) [Published : Jul 30, 2024]
Timely decontamination will reduce the consequences of a radiological contamination event. For this purpose, pressure washing can be rapidly deployed, but its effectiveness will change if the interactions between the surface and radionuclides changes as the contamination “ages” u...
