  Al-Ahsa Oasis in one of the oldest and largest irrigated agriculture in Saudi Arabia. The main source of irrigation water is the groundwater extracted from different aquifers (Neogene, Al-Khobar and Dammam). The main objective of this study was to determine the impact of water quality of Dammam aquifer on well casing and other related equipments used for pumping water. The groundwater salinity ranged between 1.81-7.36 dS m-1 at various locations in the Oasis. The high salinity of groundwater may reduce the problems of corrosion by forming protected layers from some salts such as calcium carbonate (CaCO3). The DO values ranged from 3.9-5.6 mg L-1 in the groundwater in Al-Ahsa Oasis. The SI values ranged from -0.1 to -0.5 in the northern sector, -0.4 to 0.3 in the central sector and -0.4 to 0.5 in the eastern sector. The SI values indicated non-existence of corrosion problems to well casing under the present conditions. The research findings suggest that well equipments (casings, pumps, water supply networks) should be manufactured free of corrosion problems to avoid huge income losses to the farming community. It is also suggested that well drilling should be carried in those areas where rock formation is solid and the solubility of geological material of aquifer is very low. Lastly, it is suggested that application of excess fertilizers, insecticides and pesticides should be minimized to avoid deterioration of groundwater water quality thus resulting in improving the corrosion process of well equipments.
