Abstract

The aim of this paper is to study the quality of drinking water of the Al-Ain and its surrounding, comparing it with the local and international standards. For this purpose, five samples of the different drinking water wells which supplying Al-Ain town were collected in February 2009. The physical analysis includes the following results: PH 7.07-7.50, Turbidity (N.T.U) 0.32-85. (Electrical conductivity) (µs/cm) 448+2310. Total dissolved Solids (mg/l) 263-1387. The results of the chemical analysis (mg/l) showed Alkalinity 246-266. Chlorides 63.82-364. Nitrates 16.72 – 117.48. Sulfate 137.5-500. Bicarbonate 218.3-324.5. Fluorides 0.52 – 1.55. Sodium 44.83-29.69, Potassium 1.95-20.25, Magnesium hardness (expressed as calcium carbonate) 84-204. Calcium hardness (expressed as calcium carbonate 174-518 and Total hardness) expressed as calcium carbonate 262-722. The study have shown that the drinking water of Al-Ain project is unsuitable for human requirement or use. The bacteriologic ally results show that most of the samples under study are bacteriological polluted with (Most probable number) (MPN) with degrees ranging from (100 and above).
