Decontamination of Bacillus Spores from Drinking Water Infrastructure with Physical Removal (Pigging) and Assessment of Pipe Relining Technologies
(PUBLISHED REPORT) [Published : Sep 16, 2019]
(PUBLISHED REPORT) [Published : Sep 16, 2019]
The objectives of this project were to evaluate the effectiveness of: (1) a physical scouring (pigging) technology for removing Bacillus globigii spores following intentional contamination of the Water Security Test Bed (WSTB). First responders and decision makers managing a wate...
Full-Scale Decontamination of Bacillus Spores from Drinking Water Infrastructure
(SUMMARY) [Published : May 22, 2019]
(SUMMARY) [Published : May 22, 2019]
The drinking water distribution system is vulnerable to contamination, which presents challenges to maintaining good water quality and ensuring water availability. Decontamination of drinking water systems, following an intentional contamination incident or a natural disaster, is...
Numerical Model for Decontamination of Organic Contaminants in Polyethylene Drinking Water Pipes in Premise Plumbing by Flushing
(JOURNAL) [Published : Jul 01, 2019]
(JOURNAL) [Published : Jul 01, 2019]
Polymeric materials such as polyethylene and polypropylene are used extensively for drinking water applications. These materials are subject to permeation by organic compounds, such as those found in petroleum products and industrial chemicals, which can result in water quality i...
Quantifying hydraulic and water quality uncertainty to inform sampling of drinking water distribution systems
(JOURNAL) [Published : Jan 01, 2019]
(JOURNAL) [Published : Jan 01, 2019]
Sampling of drinking water distribution systems is performed to satisfy regulatory requirements but also to respond to customer complaints or emergency situations. Water distribution system modeling techniques can be used to plan and inform sampling strategies; however, a high de...

Decontamination of Bacillus Spores from Drinking Water Infrastructure with Physical Removal (Pigging)
(PUBLISHED REPORT) [Published : Sep 25, 2018]
(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...

Adsorption of Malathion onto Copper and Iron Surfaces Relevant to Water Infrastructure
(JOURNAL) [Published : Nov 01, 2017]
(JOURNAL) [Published : Nov 01, 2017]
This study investigated the adsorption of malathion to copper and iron surfaces including pipe specimens similar to those in drinking water infrastructure.
CANARY Eases Water Quality Event Detection
(JOURNAL) [Published : Apr 01, 2017]
(JOURNAL) [Published : Apr 01, 2017]
CANARY is a free EPA software product used to enhance the detection of contamination incidents in distribution systems (i.e. Event Detection System) using typical water quality sensors such as those measuring free chlorine, total organic carbon, and electrical conductivity. Worki...
Decontamination of Bacillus spores adhered to iron and cement-mortar drinking water infrastructure in a model system using disinfectants
(JOURNAL) [Published : Feb 01, 2017]
(JOURNAL) [Published : Feb 01, 2017]
Bacillus spores are persistent on common drinking water infrastructure surfaces such as corroded iron and cement-mortar. Due to their resistance to disinfection, inactivation of spores can be used as a benchmark for decontamination of biological agents from drinking water infrast...
