This project was designed to evaluate biologically mediated corrosion and changes in water quality in municipal water distribution systems. Methods employed included a national questionnaire survey, analysis of field samples and laboratory studies. The questionnaire confirmed the vast majority of all utilities surveyed had water quality problems related to the distribution system. Actual analysis of selected samples indicated that generally there was an increase in the number of heterotrophic bacteria in samples taken from locations where water quality complaints were numerous. Studies on steel, copper and PVC pipes showed that steel pipes exhibited greater sediment accumulation, but the number of bacteria per unit area of pipe surface was essentially the same for all three pipe systems. The addition of microorganisms isolated from pipe loop systems increased the rate of corrosion.
