Abstract

Water samples collected during routine flushing of dead-end mains were analyzed for bacterial count by using both pour plate and spread plate procedures. Results from these analyses were compared statistically. The pour plate procedure was neither as accurate nor as precise as the spread plate procedure for enumerating the heterotrophic plate count population.
