摘要：This paper intends to evaluate the ground water quality with reference to drinking purpose in the Chintamani taluk, Chikkaballapur district, Karnataka. The total area occupied is about 884 Km2 and underlain by Archaean rocks. 34 ground water samples from dug wells and bore wells were collected in the year 2014 and analyzed for Hydrogen Ion concentration (pH), Total dissolved solids (TDS), Total Hardness (TH), cations (Ca2+, Mg2+, Na+, K+) and anions (HCO3-, CO3-, SO42-, Cl-, NO3-, F-, PO43-). A comparison of the ground water quality in relation to drinking water standards was made. Results show that, pH values of ground water range from 7.0 to 8.4 with an average of about 7.7, suggesting their alkaline nature and are considered to be suitable for drinking purpose. In the study area total hardness ranges from 50 to 740 mg/l with an average of about 287.9 mg/l. 41% of samples fall under Hard category and 35 % of the samples fall under very hard category. Hence, there is a need for softening of these two categories of water, if it is to be used for drinking purpose. Most of the samples are within the permissible limits as per the standards proposed by BIS (2004). Pipes trilinear plot reveals that majority of the ground water samples are alkali rich than alkaline earths (65%) followed by the strong acids rich than weak acids (62 %),implying that they are suitable for drinking purpose except very few samples which exceeds the permissible limit.
