The Water Security Test Bed (WSTB) is a full-scale representation of a drinking water distribution pipe that conveys potable water. It is the product of a partnership between Idaho National Laboratory (INL) and the Environmental Protection Agency (EPA).  Currently, the syste...

Most emergency water treatment systems are large and expensive tractor-trailer mounted systems. They can be complicated to operate and maintain (high pressures and concentrated wastes) given their reliance on reverse osmosis water treatment technology. An emergency water treatmen...

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...

This presentation discusses the efficacy of flushing, disinfection, pipe wall scouring, and relining of drinking water pipes and household appliances contaminated with Bacillus globigii, an anthrax surrogate utilizing the full-scale USEPA Water Security Test Bed (WSTB) located ne...

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...

Presentation at the WEF Knowledge Development Forum on Intelligent Water Technology Solutions

Treatment Train: •Up to 10 gallons per minute •Pre-filtration to reduce turbidity and improve disinfection •Two media filtration/adsorption tanks for targeted chemical or radiological contaminant removal (e.g. Granular Activated Carbon or Ion Exchange) •UV LED for additional ...

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...

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...

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...
