ABSTRACT

The Kaveri River quality at Kudige, Kushalnagar was studied by using physico-chemical and bacteriological parameters. Twenty physico-chemical and five bacteriological parameters were performed for water samples at three different seasons namely summer (Feb. – May), monsoon (June – Sept.) and winter (Oct. – Jan.) from Feb., 2009 to Jan., 2011. From the present research work, it was found that the statistical analysis of seasonal physico-chemical and bacteriological parameters are maximum and minimum during monsoon season of both the years. From Feb., 2009 to Jan., 2011, the COD ranges from 71.00 – 1124.00 mg/l were recorded above excessive limit prescribed by standard WHO. The magnesium of 33.66 mg/l was recorded in winter season (Sept., 2009 – Jan., 2010), 34.36 mg/l was recorded in summer season (Feb., 2009 – May, 2009) and 35.13 mg/l was recorded during summer season (Feb., 2010 – May, 2010) respectively. The statistical analysis of seasonal bacteriological parameters recorded high density of bacterial counts of 296.00 CFU/ml during summer season from Feb., 2010 to May, 2010. The MPN count of Kudige water samples found to ≥1600 MPN/100ml, in all the seasons from Feb., 2009 to Jan., 2011. Salmonella sp and Shigella spwere isolated on SS- Agar media and colony counts ranged between 1.0 – 6.0 colonies/100ml respectively. Maximum count of Shigella sp (6.0 colonies/100ml) were recorded compared to Salmonella sp. Correlation study for both seasonal physico-chemical and bacteriological parameters are carried out using standard statistical method, results were recorded and tabulated.
