Faecal contamination of water is more than 95 per cent of thermotolerant coliforms isolated from water are the gut organism escherichia coli, the presence of which is definitive proof of faecal contamination table 101 comparison of methods for analysis of coliform bacteria multiple fermentation tube technique membrane filter technique. Method 1604: total coliforms and escherichia coli in water by membrane filtration using a simultaneous detection technique e coli are those bacteria that produce blue colonies under (366 nm) (reference 168) 40 interferences and contamination 41 water samples containing colloidal or suspended particulate material can clog the. Total coliform and e coli (escherichia coli) are used as indicator organisms for fecal or sewage contamination detection of total coliform and e coli in water, food or surfaces usually points to poor hygiene and possible presence of pathogenic organisms.

As a result, testing for coliform bacteria can be a reasonable indication of whether other pathogenic bacteria are present total coliforms, fecal coliforms, and e coli the most basic test for bacterial contamination of a water supply is the test for total coliform bacteria. A specific subgroup of this collection is the fecal coliform bacteria, the most common member being escherichia coli (e coli) these organisms may be separated from the total coliform group by their ability to grow at elevated temperatures and are associated only with the fecal material of warm-blooded animals.
