Abstract

This study was conducted to analyze well waters in seven regions, Hajar, Mughynia, Nuweiba, Rabigh, Al-Abwa, Mastourah, and Kilayyah, which lie along the valleys that discharge in the Red Sea in the Western Region of Saudi Arabia. This is to evaluate and determine whether the water of these wells is suitable for drinking and agricultural use. The study included determination of the major elements Ca, Na, K, Mg, P, F, the heavy metals, Fe, Cu, Zn, Al, Mn, Ba, and the toxic metals, Ni, Pb, Cd, Cr, Ag, Mo, Co, Be, V, Ar, Sb, Ti, and U concentration in the water of these wells. The elements Na, K, P increased in the groundwater following the passage of water from upper valley to lower valley, and the elements Ca, Na, Mg, and Cl concentration in well water are affected by their nearness to the Red Sea water, and the wells of Hajar, El-nugemia and Nuweiba have the least concentrations of these elements while those near the coast, Mastourah, Rabigh, Kilayyah, and Al-Abwa contain water with high concentrations of these elements. As for the water content of the major elements, all well waters are acceptable for drinking, except Mastourah with a high concentration of Na and Mg, and Rabigh and Al-Abwa with a high concentration of Ca. All wells' water is acceptable for drinking as regards their content of the heavy and toxic metal.
