Abstract

Describes factors that influence the growth of microorganisms, particularly coliforms, in distribution systems. Determines the effect of physiology and substrate composition on coliform colonization; the influence of temperature, assimilable organic carbon concentration, disinfectant concentration, and pipewall material on microbial colonization; and field conditions that correlate with regrowth events. Validates a pipe line model to predict regrowth events. Published in 1996 as two reports: Factors Limiting Microbial Growth in Distribution Systems: Laboratory and Pilot-Scale Experiments and Factors Limiting Microbial Growth in Distribution Systems: Full-Scale Experiments.
