Previous evidence has suggested an association between consumption of unfiltered water from Loch Lomond, Scotland, and cryptosporidiosis. Before November 1999, this water had been only microstrained and disinfected with chlorine; however, since that time, physical treatment of the water (coagulation, rapid gravity filtration) has been added. To determine risk factors, including drinking water, ...

Two media were developed that allowed both a total coliform count and an Escherichia coli count to be determined on the same medium after 24 h of incubation at 35 degrees C. The new media were tested along with two standard media on 10 surface water and 7 sewage samples. The experimental media yielded equivalent or higher counts relative to the standard media and recovered more specifically the...

Water is a necessary part of life, but without proper filtration, it could cause problems such as illness or death. While citizens of developed countries may take the water that flows from their taps for granted, many parts of the world do not have access to clean water. A small village in Thailand called Nong Bua is one such community that is hindered by the quality of their water supply. Nong...

This study demonstrates that an induced bank filter (IBF) system can treat raw water polluted with Escherichia coli (E. coli) bacteria. Similar to riverbank filtration (RBF), or reversed relies on natural processes clean water, including through layers of allochthone alluvial sediments and a bioactive layer forms top the after ripening period. At site, located in Southwestern India, villagers r...
