Abstract

Tigris River considers the main resource of water for Mosul city, therefore it is of great importance to evaluate its quality continuously. In this study, chemical and physical properties of Tigris River had been studied within Nineveh governorate during the year (2012) by using the average values for ten selected sites. Computing of Water Quality Index (WQI) was done by using Weight Average (WAV) method. In spite of the large amount of the wastewater disposed into the river, the results indicated that Water Quality (WQ) in all the studied sites was suitable for irrigation purposes. For drinking purposes, only the first northern four sites were in need to simple treatment, while the following remaining sites need conventional treatment. The efficiency of the three main Water Treatment Plants (WTPs) on Tigris River were computed according to a new (WQI) that include new additional parameters and different relative weights. These three plants are; Mosul new left side (WTP), Mosul right side monotheist (WTP), and Mosul old left side (WTP). The efficiency results were (70, 62, 55)% respectively. The Low efficiency of the old plant was due to the high effluent concentrations of turbidity, SO4, total hardness, and TDS.

Abstract

Large areas of BASHEQA region haven't any source of surface water, at the same time, there are large quantities of olives trees and crops depend in its irrigating on Ground Water (GW) as a main source. So it is important to evaluate its (GW) for different uses. In this study the (GW) of 32 wells had been examined in the college of environmental science and technology laboratories to assess its Water Quality (WQ) for drinking, irrigation, and livestock purposes. Average twelve parameters (pH, Ca, Mg, Na, HCO3, SO4, Cl, NO3, EC, TDS, SAR, TH) data in the period 2008-2009 had been applied in three methods through computing Water Quality Indices (WQIS). The first method was the Weighted Average (WAV). The second one was that adopted by Ministry of Nature and Environment (MNE) of Mongolia, while the last one was the Canadian Council of Ministers of the Environment (CCME). The (WQIs) of the three methods results had been compared to assess the suitability of the best one. Although the statistical analysis indicated that there are no significant differences between both (CCME) and (WAV) methods, the (WAV) data had been used in this study as it gave more restrictive control. The analysis of (WQIs) using (WAM) method indicated that (25, 69, 88)% of (GW) are good for drinking, irrigation, and livestock purposes respectively.
