The study area was undertaken in the Kudligi taluk located in the Bellary district, Karnataka, India. The taluk consists mainly of pink and grey granite. The granites and their associated rocks constitute a portion of the Dharwar system.The assessment of water quality for its suitability for agricultural and domestic purposes was carried out. The results of chemical analysis for the major ions of 48 water samples collected from the study area of Kudligi taluk have been evaluated. The quality analysis was performed through the estimation of calcium, magnesium, sodium, potassium, iron, zinc, manganese, carbonate, bicarbonate, sulphate, chloride, fluoride, nitrate, total alkalinity, total dissolved solids, turbidity, pH, electrical conductance and total hardness. Based on the analysis, certain parameters like sodium adsorption ratio, percent sodium and magnesium ratio were calculated. The hydrochemical pattern diagram helps in hydrochemical facies classification. The trilinear diagram of shows that the majority of samples fall in Na-K-HCO3 facies followed by Ca-Mg-Cl-SO4 and Na-K-Cl-SO4 facies. In the present study, 75% of water samples can be classified as good for irrigation because most of the water samples (36/48) fall in C2S1, C2S2, C3S1, C3S2 & C3 S3 categories on the diagram. The remaining samples fall in C3S4, C4S1, C4S2, C4S3 and C4S4, not suitable for irrigation purposes as per USSL classification. The presence of E-coli in only seven dug wells indicated potential and dangerous fecal contaminations, which require immediate attention. Fluoride was most dominant ion responsible for contamination of the ground water. Fluoride concentration in 5 samples was above the permissible limit and in 9 samples showed above the excessive limit. The study indicates the need for periodic monitoring of ground water in the study area.

INTERNATIONAL JOURNAL OF PHARMACY & LIFE SCIENCES (Int. J. of Pharm. Life Sci.) Status of Groundwater Quality of Kudligi Taluk Area in Bellary district, Karnataka, India

The physico-chem and microbiol parameters of water samples from some selected areas of 15 districts in Karnataka were investigated A total of 47 water samples were collected over a period of five months Most of the physico-chem parameters are within the permissible limits of BIS and WHO stds for drinking water However, some samples show pH lower than the normal limit The fluoride content in Hassan district was very high One of the samples from Chitradurga contained very high of Nitrite content than the desirable limit Water samples were subjected to microbiol anal also Some samples were found to be highly contaminated with conforms while some other samples were suitable for human consumption Therefore, it was concluded that a few water samples were unsuitable for drinking purpose [on SciFinder(R)]
