    Abstract
    Groundwater suitability for irrigation uses in Shithatha area which is located in the west of Karbala
    governorates is determined by analysing groundwater samples of 15 wells distributed in the area, for
    two periods. Results indicated that all water samples are colourless, salty taste and with rotten egg smell
    that maybe caused by the effect of hydrogen sulfide, slightly-brackish except (W5 and W14) is classified
    as brackish water, also the samples are classified as excessively mineralized water, on the other hand
    the groundwater in the studied area is classified as very hard water depending on the total hardness
    values. The most prevalent water type is (NaCl), (CaSO
    4) and (CaCl2). The predominated water types
    are "earth alkaline water with increased portions of alkalis with prevailing sulfate and chloride" and
    "Alkaline water with prevailing sulfate and chloride". After comparing the ionic concentrations with the
    water quality standards for irrigation purposes, it is suitable for growing most types of crops, also its
    suitable depending on the sodium adsorption ratio (SAR), Soluble Sodium Percentage (Na%) and the
    Residual Sodium Carbonate (RSC)
