Water is one of the nature’s most important gifts to mankind. Groundwater supposed to be the safest source of water can also be a carrier of many diseases. Its quality depends on the goodness of recharged water, atmospheric precipitation, inland surface water and sub-surface geochemical processes. In the present study, a comparative analysis were carried out on the physical and bacteriological quality of well water samples collected from ten different locations of Kanakkary Panchayath, Kottayam district, Kerala state. The pH of water samples collected ranged from 5.24 to 7.13. The results showed that the MPN values of samples collected from five areas exceeds the World Health Organization (WHO) standards and these when subjected to confirmatory and biochemical tests showed that Escherichia coli was present only in one sample. Out of ten well water samples, three samples showed the presence of Salmonella typhi and six showed the presence of Vibrio cholerae. The Biological Oxygen Demand (BOD) values of all samples except 2 exceed the WHO standards whereas the Total Dissolved Solids (TDS) values were all as per the standards.
