Monitoring of ground water quality in the province of district Dehradun, (Uttarakhand), India

Abstract

The present study focused on the groundwater in Dehradun city to assess the quality of groundwater for determining its suitability for drinking and agricultural purposes. Groundwater samples were collected monthly from four sites of Dehradun city. Comparison of physic-chemical parameters with WHO (world health organization) and I.S (Indian Standards) revealed that, the status of groundwater is better for drinking purposes. Results indicate that physico-chemical parameters such as Temperature, EC, TDS, BOD, COD, Total Alkalinity, Total Hardness, Chloride, Sodium and Potassium were slightly increased at Site III and IV, while pH and DO were decreased. Correlation coefficient value indicates high positive and negative relationships (p<0.05 level) and also show significant positive and negative relationship between the GW quality parameters and different sites. The present study revealed water quality of all the four sites (I-IV) were better and safe and monitoring of ground water quality periodically, prevent further contamination.
