Abstract

Groundwater quality is of prime importance in determining its suitability for various human activity  such as irrigation, therefore, groundwater samples are collected from selective wells in Anah city and subjected to hydrochemical analysis in order to measure the concentrations of the major ions, in addition to the Electrical Conductivity, pH, Total Dissolved Solids, Soluble Sodium Percentage (Na%), and Sodium Adsorption Ratio)SAR( to assess the suitability of groundwater for irrigation. Results showed that the groundwater in Anah city is characterized by excellent to good SAR with good Na% and accepted value of pH for irrigation, whereas, values of Electrical Conductivity and Total Dissolved Solids were not acceptable due to the rising of salinity (SO4 and Cl). According to Piper diagram, the type of water is Earth alkaline.
