Physicochemical and bacteriological status of drinking water in pedabida, agency area, andhra pradesh

The present study was undertaken to evaluate the water quality of the Pedabida panchayat of Ananthagiri mandal in Visakhapatnam district with affable means. The physicochemical and the microbial studies are most important regions by which we are able to test the portability of water. The isolation and characterization of the pathogenic microorganism from the water sample collected were the main emphasized area of the study. In this study drinking water samples were collected from a bore, a well and a stream for a period of one years i.e., from April 2011 to March 2012. The various constituents monitored include the physicochemical characters, the bacterial parameters like Total plate count (TPC), Most probable number (MPN) and isolation and identification of pathogenic bacteria. The physicochemical characters of all the three drinking water samples were within the recommended permissible level of WHO. The total plate count was above the WHO guidelines values (<10CFU’s/ml) in the three water samples studied and the highest count was during August. The bacteria isolated were E. coli, Salmonella, Shigella, Staphylococcus, Group D Streptococcus, Vibrio cholera and V. parahaemolyticus and Pseudomonas. The samples were inoculated and were incubated at 370C for 24 hrs or 48hrs.for appropriate bacterial growths. Thus we can use this study for the assessment of the water and to resolve the hygienic problems of the water.
