Аннотация: The parameters such as PH, TDS, EC are analyzed by using portable instruments where as major Cations like Sodium, Potassium, Calcium and Magnesium are analyzed by photo spectrometer and Ion chromatography. All the Anions are analyzed in the laboratory by titration methods. From the chemical analysis of the ground water it is found that as per the Indian standards, only one sample is exceeding the permissible limit of 1000 mg/l for TDS and 2 samples are exceeding the permissible limit of Fluoride. However number of samples are exceeding the desirable limits for many individual ions such as 11 samples are exceeding in sodium concentration, 10 samples are exceeding in Calcium and Magnesium concentrations, 11 samples are exceeding in Carbonate concentration, and 9 samples are exceeding in bi- carbonate concentration. Therefore it is better to drink ground water after some treatment only. Overall central portion of the basin is some what good for drinking water. When Residual Sodium Carbonate (RSC) is taken into consideration only 3 samples are with in the limit i.e , 2.5. 5 samples are having RSC values less than 10 and the rest of 5 samples are having greater than 10.
Ключевые слова: analysis of the ground water, RSC, Sodium Absorption Ratio, TDS, EC
