Abstract

Water is a crucial constituent to sustain life on earth. For millions of rural and urban areas, the tube well water is the source for domestic use. According to one of the surveys, ground water accounts for the 50% of urban water requirement.

Water Quality Index is developed for all the samples considering various parameters like pH, Temperature, Total Suspended Solids, Turbidity, Total Dissolved Solids, Total Hardness, Electrical Conductivity, Sodium, Potassium, Ca, Mg, Cl, HCO3, CO3, NO3, F, SO4, PO4, Cr+6, Fe, Cu, Pb, Ni, Zn. The quality of water found is excellent and suitable for drinking purpose.
