Abstract:

Groundwater is one of the most important sources of freshwater in Egypt, with specific reference to cities located away from the River Nile. Unlike surface water, groundwater is not directly subject to pollution. However, owing to its generally very low velocity, groundwater once contaminated will often remain so for many generations to come. Because the process of groundwater pollution is generally lengthy and also due to the low velocities of groundwater, contamination is more likely to be discovered after twenty or thirty years from its initiation so numerical models are vital to predict and study the behavior of contaminant movements under different conditions. In the Sadaat city, various natural and waste or sewage water are stored and spread on, or beneath land surface through oxidation ponds, where they are susceptible to percolation. This study presents the effect of the oxidation ponds on groundwater quality …
