Investigate Hydrochemical Properties of Arnaveh Spring

The current paper aims at investigating the hydrochemical properties of Arnaveh spring water resources. This spring is used for drinking and agriculture and is located in Shirin Dareh catchment. The paper collected and investigated samples values of EC, TDS and main ions. The Piper and Chad diagrams showed that the water type was Ca-Mg-HCO۳ and Ca-Mg-SO۴. The average electrical conductivity of the samples is about ۹۰۰ micromoles per centimetre, with insignificant spatial and depth change. According to the SAR factor, water quality is optimal for agriculture and according to the WQI index, the quality of drinking water is in the good range
