Bahar Al-Najaf basin is located in the western part of Al-Najaf governorate, center of Iraq. This work was aimed to determine the water sources for marshes, water discharges and factors which causing to the rise and low of the water level in these marshes.Five sources recharge for the marshes water were detected; rainwater, Al-Dammam confined aquifer flowing wells, sieve factures, water of springs and the irrigation water.The hydrochemistry analysis was investigated for all water sources of marshes using major and minor elements (Ca, Na, K, Mg, Cl, SO4, NO3, HCO3 and Br) and field measurements such as (T, pH, EC, TDS). The hydrochemical results shows that the all sources of water are not suitable for drinking water, while it’s classified as a good to permissible water for irrigation except water of marshes. Water quality standards for livestock is vary from very good water type in the irrigation streams to the can be used in a water marshes.
