Description:
Water quality degradation due to the growth of microorganisms Is an area of concern for many water utilities. urrently the nutrient status of drinking water is difficult to measure and can only be defined in relative terms. o date, the procedures developed for determining the amount of biodegradable material present in potable water have-utilized heterotrophic non-coliform bacteria as bioassay seed organisms. ethod for determining the growth potential of treated water for coliform bacteria was needed to assist in evaluation of the potential for coliform regrowth or colonization in treated water-systems. A procedure was developed which utilized coliform bacteria as the bioassay organisms for determining the ability of the water to support and promote growth of coliform bacteria. his procedure was compared with a reference assimilable organic carbon (AOC) bioassay.
