Evaluation of Groundwater Quality and its Usability in the Teeb Hydro geological Basin, East Iraq

Abstract

Teeb Hydrogeological Basin is locating in east part of Iraq. The studied area is characterized by the presence of confined and unconfined aquifers which are represented by Tertiary (Mukdadiya Formation ) and Quaternary deposits respectively. The climate is classified as dry to semidry. The general flow direction of groundwater is concordance with the topography from north-northeast to south-south west. Groundwater hydrochemical study in the basin depends upon (18) well samples where major cations and anions were obtained. The hydrochemical properties include the study of (pH, EC, TDS), the type of groundwater is sodium sulfate (Na SO4 ). The groundwater is generally of suitable chemical quality for livestock, irrigation, and unsuitable for drinking purpose.
