Abstract:
Quantity and quality are two vectors of ground water management. While former refer to as resource and the latter refer to its usefulness. The analytical data of 314 ground water samples of Hyderabad city indicate that, in general, most of the chemical constituents are within permissible limits in majority of samples. The electrical conductivity (EC) of ground water in areas around chemical industries are beyond consumer's acceptance. The nitrate content in ground water far exceeded the permissible limits in about 60% of the total area. The presence of high nitrates is mostly attributed to domestic pollution like sewage and solid waste. About 85% of the samples fall under very hard category.74% of the samples have chloride within desirable limits. Except in small isolated patches, the flouride content in ground water is within permissible limits. The SAR and RSC values indicate that the ground water is mostly fit for irrigation.
