A variety of water types collected from different geographical areas at different stages of water treatment were analyzed for their ability to support the growth of coliform bacteria. Based on this coliform bioassay, the nutrient status of the water did not correlate with any of the measured water quality parameters except assimilable organic carbon. Significantly higher coliform growth responses were associated with waters that had been exposed to ozonation. The authors conclude that the coliform bioassay procedure is a viable method for ascertaining the biological stability of drinking water supplies.
