The biological safety of distribution systems following UV disinfection in rural areas in Beijing, China
In rural areas, UV disinfection has a great potential for drinking water treatment because of the ability to achieve target disinfection levels and the ease of operation and maintenance; however, UV disinfection provides no disinfection residual to the water distribution system. This study examines the biological safety of rural water distribution systems following UV disinfection. The results ...

A sensitive presence/absence test kit for detection of coliforms in drinking water
Coliforms are the most widely accepted bacterial indicator of fecal pollution in water. Several commercially available portable kits make it possible to carry out on-site water quality testing, but are usually costly and often require technical expertise to operate. In developing countries like India, presence/absence test kits like the H2S test kits are commonly used for routine ...

Project - Fenton Leads the Way in Water Testing - City of Fenton (USA)
Fenton is a classic rural American city nestled approximately 65 miles north of Detroit in the state of Michigan. Although not one of the bigger metropolises’ in the US, Fenton takes pride in its use of new technologies to better serve its residents. One Example would be the State-of-the-Art Water Treatment Facility, in which current staff helped start-up. When Superintendent Stephen Guy ...

Microbiological quality of ice and ice machines used in food establishments
The ice used in the food industry has to be safe and the water used in ice production should have the quality of drinking water. The consumption of contaminated ice directly or indirectly may be a vehicle for transmission of pathogenic bacteria to humans producing outbreaks of gastrointestinal diseases. The objective of this study was to monitor the microbiological quality of ice, the water ...

Development and validation of a FISH-based method for the detection and quantification of
E. coli and coliform bacteria in water samplesMonitoring of microbiological contaminants in water supplies requires fast and sensitive methods for the specific detection of indicator organisms or pathogens. We developed a protocol for the simultaneous detection of E. coli and coliform bacteria based on the Fluorescence in situ Hybridization (FISH) technology. This protocol consists of two approaches. The first allows the direct detection of ...

Comparison of MI, Chromocult® coliform, and Compass CC chromogenic culture-based methods to detect Escherichia coli and total coliforms in water using 16S rRNA sequencing for colony identification
The MI, Chromocult® coliform, and Compass CC chromogenic culture-based methods used to assess water quality by the detection of Escherichia coli and total coliforms were compared in terms of their specificity and sensitivity, using 16S rRNA sequencing for colony identification. A sewage water sample was divided in 2-μL subsamples for testing by all three culture-based methods. All growing ...
