Evaluation of the Environmental Impacts of Water Disposal Associated With Crude Oil Production on El-Moghra Aquifer in Abu El-Gharadig Basin, South East Qattara Depression

Abstract

/year. This is due to the limited water resources compared with the water demands. The physical and chemical properties of the groundwater differ from surface water related to the environment in which it occurs. Groundwater is affected by surface activities, rainwater, seepage, irrigation water and drainage water and other effluents. Shortage of water sources in Egypt bring out the issue of using non-conventional water resources.Industrial activities represent the most hazardous source of ground water pollution and disposal lagoons for water associated with crude oil production represent the main source of pollution to Moghra aquifer in the study area. The large quantities of water drained daily to the un-lined disposal lagoons, facilitate the salt water intrusion to the aquifer layer. There are three main water disposal lagoons in the study area, the surface area of the main lagoons ranges from 0.08 to 2.08 Km
