Persistence of Surrogates for High Consequence Viral and Bacterial Pathogens in a Pilot-Scale Activated Sludge Treatment System
(JOURNAL) [Published : Oct 07, 2022]
(JOURNAL) [Published : Oct 07, 2022]
This study utilizes organism viability to evaluate the persistence of three pathogen surrogates in bio-contaminated wastewater using a pilot-scale activated sludge treatment (AST) system, operated to perform like a large-scale wastewater treatment process.
The persistence of high...

Bioaerosol Emissions of Bacillus anthracis Surrogate Spores from Aqueous Media
(PRESENTATION) [Presented : Oct 21, 2021]
(PRESENTATION) [Presented : Oct 21, 2021]
We studied bioaerosol release using Bacillus globigii spores at three scales as well as the effectiveness of the potential bioaerosol mitigation strategy, free-floating carrier media (FFCM), to suppress bioaerosol emission. We studied both physical and diffusion aeration me...
Informing remediation of benzene contamination in drinking water distribution systems through multi-criteria decision analysis
(JOURNAL) [Published : Nov 01, 2021]
(JOURNAL) [Published : Nov 01, 2021]
During WSD's review of its recent "Decontamination Preparedness and Assessment Strategy", reviewers requested a "how-to" tool for completing some technical aspects of the strategy, specifically those related to selecting technologies for water treatment and system decontamination...
Persistence of Surrogate Radionuclides on Wastewater Collection System Infrastructure
(PUBLISHED REPORT) [Published : Mar 31, 2021]
(PUBLISHED REPORT) [Published : Mar 31, 2021]
EPA Report; Results for cesium and cobalt showed that metal adhesion to conditioned infrastructure materials was undetectable. Strontium was detected on concrete coupons at levels above the method detection limit. However, further analyses of the concrete suggested that stront...

Persistence and Decontamination of Radioactive Cesium in a Model Drinking Water System
(PUBLISHED REPORT) [Published : Jul 17, 2018]
(PUBLISHED REPORT) [Published : Jul 17, 2018]
The objective of this report was to evaluate the persistence of radioactive cesium-137 (Cs-137), on concrete-lined, copper, and polyvinyl chloride (PVC) pipe, and possible decontamination approaches. During this study, conditions within operational drinking water pipes were simul...
The effectiveness of disinfection and flushing procedures to prevent coliform persistence in aircraft water systems
(JOURNAL) [Published : Dec 24, 2018]
(JOURNAL) [Published : Dec 24, 2018]
Maintaining safe water on board commercial aircraft is critical to the safety of passengers and compliance with regulations. The conclusions from this study can help commercial air carriers deliver safe water by indicating that coliform bacteria are not persistent on aircraft plu...
