A Bench-Scale Procedure for Evaluating Chlorine Bleach Inactivation of Bacillus Spores in Wash Water from a Cleanup of a Site with Biothreat Agents
(PUBLISHED REPORT) [Published : May 02, 2019]
This report describes a streamlined bench scale procedure which has been developed for testing the efficacy of chlorine bleach for the inactivation of Bacillus spores in wash water originating from a cleanup of a site contaminated with Bacillus anthracis spores.
Chlorine and monochloramine disinfection of Legionella pneumophila colonizing copper and PVC drinking water biofilms
(JOURNAL) [Published : Jan 25, 2019]
Building water systems (BWSs) promote the regrowth and survival of opportunistic pathogens, such as Legionella pneumophila, especially within biofilms (BFs), where most drinking water (DW) microbes reside. However, compared to their planktonic (PL) form, disinfection efficacy fo...
Evaluating Solid Sorbents for Recycling Wash Waters Containing Strontium and Calcium
(JOURNAL) [Published : Jan 01, 2019]
A radiological release from a radiological dispersal device (RDD) or an improvised nuclear device (IND) has the potential to contaminate a vast area both near the dispersal epicenter and via atmospheric deposition of small particles containing the more volatile contaminants. Rapi...

Decontamination of Bacillus Spores from Drinking Water Infrastructure with Physical Removal (Pigging)
(PUBLISHED REPORT) [Published : Sep 25, 2018]
This report summarizes the results of biological decontamination experiments performed at the WSTB focused on removing Bacillus globigii spores adhered to the inner surface of the 8-inch water pipe. B. globigii spores are a non-pathogenic surrogate for B. anthracis, which is the...
Electrolyte Selection and Microbial Toxicity for Electrochemical Oxidative Water Treatment Using a Boron-doped Diamond Anode to Support Site Specific Contamination Incident Response
(JOURNAL) [Published : Apr 06, 2018]
This journal article study addresses such concerns by demonstrating successful boron-doped diamond (BDD) electrochemical advanced oxidation process (AOP) pre-treatment for contaminated waters prior to discharge to wastewater treatment facilities.

Evaluation of and environmentally sustainable UV-assisted water treatment system for removal of Bacillus spores in water
(JOURNAL) [Published : Jun 29, 2018]
In both developing and industrialized nations, a growing number of contaminants are entering water supplies from human activities. In addition, the events of September 11, 2001, in the United States have raised concerns about the potential for intentional contamination of water s...
Persistence and Decontamination of Radioactive Cesium in a Model Drinking Water System
(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...
