EVALUATION OF SUBSURFACE WATER QUALITY BY ESTIMATION OF PHYSICO- CHEMICAL PARAMETERS - A CASE STUDY

摘要

To meet the increasing water demands, reliance on groundwater has been rapidly increasing, especially in the arid and semiarid regions. Overexploitation of groundwater leads to deterioration of groundwater quality. The present study was undertaken toascertain groundwater quality in view of the potability. Groundwater samples at various locations were collected and analysed for some selected physico-chemical parameters such as pH, Specific Conductance, TDS, hardness, total alkalinity, chlorides, calcium, nitrates and sulphates. Except pH, all the collected percentage of samples are above the desirable limits. Correlation coefficient among selected water quality parameters were computed. Recommendations were made to improve the groundwater quality.
