Assessing and Controlling Bacterial Regrowth in Distribution Systems

Abstract

Provides guidance on assessing the extent and relative importance of biofilm and biological activities on water quality deterioration in distribution systems. Demonstrates which methods and procedures effectively evaluate the potential for biological problems and identifies specific practices to control such problems. Published in 1989.
