Hydrochemical evaluation of groundwater in the Sharbazir district in the Sulaymaniyah Governorate/Iraq

Abstract

     This study is concerned with evaluating the validity of the groundwater in the Sharabazir district in the Sulaymaniyah / Iraq Governorate for multi -consumption (human, animal, agricultural, industrial), The water samples were taken from (11) wells during two seasons of (2022), which represented the winter season with January, while it was monitored the month of August, the summer season, Quality analyzes have been conducted (Physical and Chemical) has in laboratories (Ministry of Science and Technology / Laboratory Department) and in (Karbala Governorate Health Directorate / Karbala Health Laboratory),  These analyzes included ions (EC, TDS, PH, T.H, Ca, MG, NA, K, CL, SO4, No3, HCO3), then the sodium addation rate (SAR) was calculated, And the percentage of sodium (NA%) to compare it with the global standard specifications. The study concluded that the qualitative hydrological properties in the Sharbazir district vary in time and space in the study area, The study also showed that all samples taken of groundwater are suitable for human consumption, while all samples and both seasons are within the classification (S1 Sodium) in relation to the value of (SAR),  And its water is appropriate to irrigate most crops and for almost most of the soil varieties except for the very sensitive crops for sodium, As for the TTOD classification and the American salinity laboratory, all well samples were suitable for agricultural consumption, While all the studied samples were valid for animal consumption after comparing them with the required global measurements according to the Crist and Lowry classification, With regard to industrial consumption, all well samples were valid for all industries according to the classification of (Salvato) classification and for both seasons (except for the paper industry) that were outside the borders of both seasons because of the high concentrations of chemical variables.
