ABSTRACT
The present study was undertaken to evaluate the water quality of the
Addatheega Village Gantyada mandal, Vizianagaram dist. 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 5 sources i.e., three
different bores, a well and a spring. 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 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.
