| Abstract |
The turbidity standard for water quality was evaluated in relation to total particle counts, heterotrophic plate counts and epifluorescence direct cell counts of three different municipal drinking-waters. Turbidity and particle counts were directly proportional. There was no predictable relationship between bacteriological quality and turbidity or particle counts. Heterotrophic plate counts underestimated epifluorescence direct cell counts by a factor of at least 500. Water quality degradation occurred in municipal drinking-water systems because of intermittent short duration events that resulted in high turbidity, particle counts and heterotrophic plate counts. Further, for all parameters measured variability increased with distance traveled within a pipe except for ground water. |
