A variety of water types collected from different stages of water treatment from different geographical areas were analyzed by bioassay for their ability to support the growth of coliform bacteria. The results of the analyses were compared with other water quality parameters. The nutrient status of the water, based upon the coliform bioassay, did not correlate with any of the measured water quality parameters except assimilable organic carbon (AOC). In general, the coliform growth response increased with increasing levels of AOC. Differences were seen between the coliform growth response and various treatment types, with significantly higher responses being associated with waters which had been exposed to ozonation. The coliform bioassay procedure provides a viable method for ascertaining the biological stability of drinking water supplies.
