Water is the most important component of life. Natural sources affecting quality of water are lithological, climatic, hydrological, topographical and atmospheric factors. Pollutants accumulate in the water bodies because of extensive economic and social growth resulting in the variation of quality of the source of water.To determine drinking quality, groundwater samples from different locations of the study area are drawn as per APHA and tested as per the standards given by APHA and IS. Samples are tested for various parameters such as pH, TDS, total hardness, total alkalinity, Ca2+, Mg2+, Cl- , F-, SO42-and NO3- ions. Using values of various parameters, water quality index (WQI) of the study area is determined.
