Sodium ion concentration in the ground water varies from 7.82 to 448 mg/l with an average
value of 124.41 mg/l . The calcium ion concentration varies from 20 mg/l to 320 mg/l with an average value of 109 mg/l. All the samples are with the permissible limits. Potassium concentration is comparatively low. Bicarbonate, the dominant anion in the study area,
varies between 30.5 mg/l and 750 mg/l (average 431mg/l). chlorides occur in all natural waters in widely varying concentrations. The chloride content normally increases as the mineral content increases (Sawyer and Mccarty 1978). Chloride varies from 88.75 mg/l to 1109
mg/l (average 327 mg/l).
