Suitability of Groundwater Quality with Precipitation in the Western Part of Indo-Gangetic Plain, Uttar Pradesh

Abstract

In this study, the study area has been classified into two parts as the city area and the critical area on the basis of different uses and demands. About two decades groundwater samples were collected and analyzed for the drinking and irrigation water quality parameters such as water quality index (WQI) and sodium absorption ratio (SAR) respectively. A graph has been plotted amongst water quality index, SAR values, and precipitation. It shows that WQI of critical area and city area is directly proportional to SAR values while the precipitation has a reverse correlation with the SAR and WQI for both the areas at a certain range. The response of precipitation and parameters is not the same for both the areas because the availability of open area is high in critical areas while very low in the city area. Each groundwater sample was also analyzed for both the parameters and also compared with the standards of World Health Organization, 2017, and Bureau of Indian Standards, 2012. Therefore it can be suggested that a proper drainage network and water harvesting structures should be constructed for the heavy rain period and lean period respectively for the sustainable groundwater resources.
