Seventy samples of groundwater were collected from different parts of Yavatmal District, India and analyzed. The results of this analysis were compared with the WHO water quality standards. The groundwater quality in this district showed slightly seasonal variation while the data computed in Water Quality Index (WQI) calculator. The WQI was varied from 73.0 to 80.2 during pre monsoon and 68.7 to 72.4 in post monsoon season, which showed slightly seasonal variation. This may be attributed to surface runoff and percolation process. The results showed that, the water in these areas are bacteriologically not safe and need treatment before it is used for drinking.
