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.

Abstract

This research has been carried out to determine the quality and use of water of Bawashaswar Dam based on the physical and chemical parameters. Twelve water samples were taken from different locations within the dam's reservoir; then, analyzed for physical and chemical parameters such as pH, electrical conductivity (EC), total hardness (TH), chloride (Cl-), sulphate (SO42-), bicarbonate (HCO3-) nitrites (NO3-), total dissolved solids (TDS), magnesium (Mg2+), calcium (Ca2+), sodium (Na+), and potassium (K+). The concentrations of these constituents were measured and interpreted with some water quality indices such as sodium adsorption ratio (SAR), residual sodium carbonate (RSC), magnesium hazard (MH%), and Kelly’s ratio (KR). Compared with irrigation water standards and water quality for fisheries life, the characteristics of water in the reservoir revealed that the most measured parameters were acceptable. However, high values of turbidity, TDS and RSC in some sites basis on drinking water standards revealed that water in the dam needs proper treatment before distribution for public consumption.

يهدف البحث إلى تحديد مؤشر جودة المياه لبحيرة سد باوه شاسوار في مدينة كفري اعتماداً على الخصائص الفيزيائية والكيميائية. حيث تم أخذ العينات من اثنى عشرة مواقعاً مختلفاً من البحيرة . وقد تم تم إجراء التحاليل الفيزيائية والكيميائية لمياه البحيرة مثل النترات، العكارة، الاوكسجين الذائب، الناقلية الكهربائية، درجة الحموضة، مجموع المواد الصلبة الذائبة، إضافة الى بعض الأيونات السالبة والموجبة. تم تمثيل النتائج ومقارنتها مع القيم المسموحة لمياه الشرب والزراعة وتربية الاسماك وفق المواصفات القياسية لمنظمة الصحة العالمية. أظهرت النتائج أن معظم مؤشرات نوعية المياه كانت ضمن الحدود المقبولة، إلا ان النتائج اظهرت قيماً عالية من العكورة، مجموع المواد الصلبة الذائبة، وكاربونات الصوديوم المتبقية. وبناءاً على نتائج المؤشرات تبين أن المياه لا يمكن استخدامها للشرب مباشرة بل تحتاج إلى عمليات المعالجة المناسبة قبل التوزيع للاستهلاك العام.
