Evaluation of Ground Water Quality in Al-Qush – Tel Kafe Area, North Mosul City

Authors:

Abstract

Al-Qush – Tel Kafe area located within the rain precipitate contour line 400mm./year. This average were suitable for agriculture, but many years with low precipitation may cause failure in the agriculture generation. This study suggests to exploit the ground water of shallow wells for drinking, domestic and irrigation in low precipitate periods. The chemical compositions and sodium content (SAR & Na%)are suitable for drinking and other domestic and agriculture uses, these parameters classified the water as moderate salinity, low sodium content and moderate damage for agriculture yields, except water of Zayton 1&2 wells which are saline water, damage for agriculture yields due to their reservoir rocks of evaporates in Fatha Formation.

Abstract
Al-Qush Tel Kafe area located within the rain precipitate contour
line 400mm./year. This average were suitable for agriculture, but
many years with low precipitation may cause failure in the agriculture
generation. This study suggests to exploit the ground water of shallow
wells for drinking, domestic and irrigation in low precipitate periods.
The chemical compositions and sodium content (SAR & Na%) are
suitable for drinking and other domestic and agriculture uses, these
parameters classified the water as moderate salinity, low sodium
content and moderate damage for agriculture yields, except water of
Zayton 1&2 wells which are saline water, damage for agriculture yields
due to their reservoir rocks of evaporates in Fatha Formation.
Article
Groundwater is an important resource, especially in areas where water resources do not meet the requirements of life. Therefore, population centers in areas far from rivers are linked to the quantity and quality of groundwater available. The study area represents a large part of the eastern part of Nineveh Governorate, which is dotted with small cities and villages with population and agricultural activity. The quantity and quality of groundwater are related to the nature of the reservoir rocks in the region, which are mainly represented by the Pila Spi Formation, composed of dolomite limestone, the Fat’ha Formation, composed of periodic successions of marl, limestone, and gypsum, and the Injana Formation, composed of periodic successions of sandstone, siltstone, and clay. The quality of the rocks exposed in the study area, especially at the feet of the Bashiqa and Ain Al-Safra mountains, and the ability of the minerals that make up them to dissolve in conditions of weathering and erosion also affect the water content of dissolved salts. The water quality index (WQI) was calculated to determine its suitability for civil use based on the physical (pH, E.C, T.D.S and T.H) and chemical (Ca2+, Mg2+, Na+, K+, HCO3-, SO42-, Cl- and NO3-) specifications. In light of this, the distribution of wells was determined according to their specifications. In general, there were six regions; The first in the northern part has excellent water, the second in the south has good water, the third in the south has unsuitable water, and the fourth area, which represents the area confined between the city of Mosul and Mount Bashiqa, has poor water quality, while the area adjacent to Ain Al-Sufra Mountain is classified as having good water quality, while The area located to the southwest towards the Tigris River is of very poor quality. There are sites for wells whose specifications vary according to the type of activity there.
