Amir Reza Nemati, Behrooz Nemati, Mohammad Reza Pirestani

Abstract


In this study, the quality of groundwater resources of Saveh plain was investigated based on water quality index (WQI). WQI index is based on use of magnesium (Mg), sodium (Na), potassium (K), sulfate (SO4), chloride (Cl), Total solids (TDS), bicarbonate (HCO3), calcium (Ca) and pH which determines the class of water quality. The required qualitative data were collected from12 wells at Saveh plain and WQI index was calculated. Based on WQI index from the needed 12 wells, 2 wells were at High class, 5 wells were at the appropriate class, 4 wells in weak class and 1well in very weak class. Based on WQI, the more we move from West ,the groundwater quality reduces, in the way that the quality of ground water in western areas of plain are in High class and in the eastern areas of the plains are in the weak class.
