Groundwater Quality Index Mapping using Geoinformatics Approach
In present study, water quality index has been used for evaluation of the groundwater quality of Gurugram district. Water samples were collected from 31 sites in post-monsoon and pre-monsoon seasons for the year 2013-14. Eight water quality parameters namely pH, alkalinity, hardness, chloride, total dissolved solids, electrical conductivity, nitrate and fluoride were used for calculation of water quality index. These eight parameters contribute maximum for determining the drinking water quality. The figured WQI shows that 19% of water test falls in the 'good' to 'medium' water class in the pre-rainstorm though 29% in post-storm. Then again, 81% of water tests fall in the 'Bad' to 'Very Bad' classification in pre-rainstorm while 71% in post-storm showing that the water isn't reasonable for direct utilization and require treatment. After treatment, the water can be utilized for drinking purpose. In this study Groundwater Quality Index Map has been prepared using Geoinformatics. This map is very useful for easy and quick understanding of water quality.
