Viability of the ground of Shithatha, western Iraqi plateau, for industrial and commercial uses via hydrochemistry analysis

Abstract

Iraqi western plateau is considered as one of the most resourceful areas of the middle east, that is not yet well explored, due to the many political disturbances and security issues. The viability of underground water for the various industrial, municipal, commercial and agricultural uses is examined for Shithatha, Karbala governorates as a representative for the western plateau via chemical and physical analysis of water samples that are taken from 9 wells and 3 springs all-around the study area during the wet and dry periods. Hydro chemical and statistical analysis for the field samples have proved that groundwater of the studied area is classified as slightly-brackish water and water hardness is very high. Also, the results of the analyses of trace elements in the groundwater of the study area have confirmed the contamination of groundwater with some elements such as (Fe, Cd, Pb, Ni) in concentrations that have exceeded the WHO and Iraqi national standards IQS, permissible limits. The application of Hydro-chemical formulae of Kurlouv and Piper, Schoeller, Stiff classifications have demonstrated that most samples of the study area have water type of (Na2SO4) while other samples have ranged between (MgSO4), and (NaCl) water type. The quality of groundwater is unsuitable for drinking and industrial purposes and it is almost suitable for irrigation purposes, but it is suitable for livestock, building and agricultural purposes because the salinity of the water is within the permissible limits when considering the nature of the soil.
