Abstract:
An assessment of water quality, heavy metals and coliform content in drinking water samples from mining and non-mining areas of Hospet and Sandur talukas of Ballari district was carried out. The physico-chemical variables such as pH (7.2), total dissolved solids (179mg/l), total hardness (61 mg/l), calcium (19.5 mg/l), magnesium (5.1mg/l), sulphate (19mg/l) and nitrate (0.2mg/l) contents in mining area were slightly higher compared to water samples of non-mining area, but both were in the acceptable level of Bureau of Indian standards (BIS) and Indian Council of Medical Research (ICMR).The chloride and fluoride contents were present in both water samples of mining and non-mining areas did not differ (24mg/l and 0.2mg/l) and were within the desirable limits of Bureau of Indian standards (BIS) and Indian Council of Medical Research (ICMR) (30mg/l and 1.0 mg/l respectively).The heavy metals such as cadmium, arsenic, lead, mercury, zinc and copper were not detected in both the water samples. Though the traces of iron was detected in water samples of mining area (0.16 mg/l) but were within in the desirable limits. Total coliforms content of water from mining and non-mining area were within the desirable limits of BIS and ICMR (1MPN/100ml).
