Seasonal Variation In Water Quality Index Of Ground Water Of Osian Region, Jodhpur India

Abstract

The present study is carried out to assess the water quality index (WQI) for the ground water of Osian Region of Jodhpur district to examine the suitability of water for drinking and irrigation purposes. For this, ten water samples were collected during pre- monsoon and post-monsoon seasons in the month of June and November 2013 respectively. The samples were analyzed for the physico chemical parameters like pH, Conductivity, total dissolved salts (TDS), total hardness (TH), calcium, magnesium, nitrate, chloride, sulphate, etc. Water quality index provides a single number to express the overall quality of water at a certain location and time based on several water quality parameters. WQI help us to convert the complex water quality data in to simple information which can be understandable and useable by the public. The value of water quality index obtained in present study ranges from 68.9 to 146.3 in pre monsoon and 64.8 and 143.5 in post monsoon seasons respectively.
