In developing countries, a large portion of the population, suffers from health problems associated with either lack of drinking water or due to the presence of microbiological contamination in the water. To have an understanding about the drinking water quality, 4 drinking water samples were collected, out of which 3 were from Shimati Indira Gandhi College campus, Trichy and 1 from common municipal water tank near Karur bye-pass road, Trichy. It was found that the temperature of the water collected from all 4 sites were within the permissible limit as per IS: 10500. The fluctuation of pH in the samples is from 7.32 to 7.53 and the turbidity ranged from 2.31 to 2.56 NTU which was within the prescribed limit for drinking water. Among the 4 samples collected water collected from the municipal tank showed high incidence of bacteria compared to all the 3 samples. Isolated colonies were subjected for identification by macroscopy, microscopy and biochemical tests. Water samples 1 & 2 were considered as potable and water sample 3 & 4 were non-potable by MPN technique. Among all the vessels used copper was found to be effective for storing water since it exhibited antibacterial property against E.coli and Klebsiella sp, tested.
