Decontamination of Drinking Water Distribution System Infrastructure after Contamination with Untreated Source Water
(PUBLISHED REPORT) [Published : May 31, 2020]
This report summarizes the results of infrastructure decontamination experiments performed at the WSTB. These experiments focused on simulating contamination of drinking water distribution pipes with untreated source water due to a treatment failure at a water treatment facility...
Fire Hydrant Flushing Treatment Diffusser and Effectiveness of Flushing Hydrants for Contamination Removal
(SUMMARY) [Published : Jul 31, 2020]
Flushing contaminated water out of the distribution system using the existing network of fire hydrants is considered the most probable first action in response to a drinking water system contamination incident. Hydrant Flushing and Chlorination experiments were conducted at the W...
Functional categories of microbial toxicity resulting from three advanced oxidation process treatments during management and disposal of contaminated water
(JOURNAL) [Published : Jan 20, 2020]
Contaminated waters could contain harmful chemicals, which present management and disposal challenges. This study investigates three The results indicate that AOP pre-treatment can be a viable strategy to facilitate drain disposal of contaminated waters, but that eco-toxicity may...

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...
Design, Testing, and Deployment of a Mobile Emergency Water Treatment System
(PUBLISHED REPORT) [Published : Jun 01, 2019]
This mobile treatment technology system in this study is referred to as the Water-On-Wheels (WOW) Cart. The mobile system originally consisted of a pre-filter, an on-site chlorine generator, and a pump attached to a dolly or frame with wheels. The frame also provided space to st...
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...

AN OVERVIEW OF THE WATER NETWORK TOOL FOR RESILIENCE (WNTR) - Canada
(PAPER IN NON-EPA PROCEEDINGS) [Published : Jul 25, 2018]
WNTR integrates hydraulic and water quality simulation, a wide range of damage and response options, and resilience metrics into a single software framework, allowing for end-to-end evaluation of water network resilience. WNTR includes capabilities to 1) generate and modify water...
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]
