Ground Water Exploitation and its Relation to the Water Quality Deterioration Conditions of Sana'a Drinking Water Supply

Abstract

#Yemen such a developing arid country suffers a lot of water-related health problems. The predominant health problems are still the communal diseases, which result from identifiable features of the environment, such as lack of water, lack of a protected water supply, and inadequate waste disposal. Motivation for this study grew out of concern over groundwater drought and contamination in the Sana'a basin, Republic of Yemen, which have become recently some of the most important problems that require an intensive attention to be studied widely, and properly understood. Our paper is intended to study the chemical qualitative properties of Sana'a drinking water. Studies in this aspect received very little attention. The analyses of 31 water samples taken from different sources of Sana'a drinking water supply indicate unacceptable levels of various samples concerning the Fluoride, Nitrate, Iron, and Sulphate. This causes serious problems by exceeding the maximum tolerable concentration given by WHO and National guideline values. Meanwhile there are numerous numbers of water samples of different origin, which possesses acceptable levels of the given common parameters shown in tables, which decided the quality of our drinking water in Sana'a. The variations in concentrations of the above four ions may be attributed to the nature of the geological and chemical structure of the rocks and soil for each region, the depth of the wells, as well as the contamination due to the west water disposal.
