Monitoring and managing groundwater quality is of major environmental distress. Inadequate availability of surface water makes people dependent on groundwater to accomplish their needs. Hence, it cannot be optimally used and sustained unless the quality is assessed. Quality assessment, can be done using water quality index (WQI), is a mathematical expression applied to transform large quantity of data into a single number which indicates the level of water quality. The present study is intended to evaluate the quality and suitability of groundwater for potable use during 2019–2020. The study evaluates the physico-chemical parameters, such as EC, TDS, pH, alkalinity, Ca, Fe, NH4, NO2, NO3, Cl and PO4 remained used for the assessment. Geographical coordinates were obtained using GPS receiver for continuous monitoring. The results revealed that the WQI of groundwater at the focused area is 28.84 and stipulates that the water is good for drinking purpose as comes under excellent category. The study delivers comprehensive depiction which is easily interpretable in lieu of the decision makers for better planning and management of water resources along with their development methods are elaborated.
