Application of Water Quality Index to Monitor Groundwater Quality in Nagpur City
The present work is aimed at assessing the seasonal (pre-monsoon and post-monsoon) water quality index (WQI) for the groundwater of different areas of Nagpur city during the year 2006-2007. 15 locations (45 samples in each season) for three alternate weeks were studied for comprehensive, bacteriological and physico- chemical analysis. The WQI for these 15 locations ranges from 76 to 83 in pre-monsoon and 68 to 82 in post- monsoon season. Only 13% of the locations (two locations) showed the quality change from good to medium and other 87% showed variation in WQI but not change in water quality. The analysis reveals that the groundwater of few areas needs some treatment before consumption, and it also needs to be protected from the perils of contamination.
