Abstract

The aim of this pilot study is to investigate the quality of well water in Ahad Rofidah of Assir, Kingdom of Saudi Arabia. Six samples were collected for the physical and chemical analysis during the month of April 2008. The results of the chemical analysis (mg/L) were: Magnesium hardness 4.52 - 1488, Calcium hardness 5.04 - 26,57 Total hardness 84,0 - 268.0, Total Alkalinity 50.0 - 240, Chlorides 100 - 1600, Nitrates 88.0 – 176,0, Sodium 86.0 – 90 1.0, Potassium 76 - 43.1, Bicarbonates 50 - 124, Sulfates 145 - 1200, and Total Dissolved Solids 314-1179, pH 7.09- 7.66, Electrical Conductivity (ms/cm) 1636-2360. A comparison between the obtained results with those of the national and international standards indicates that the water of these wells is not appropriate for drinking, nevertheless, it can be used for other purposes, such as household and irrigation uses. It is recommended that a detailed study on the quality of groundwater to be carried out in the region.
