Abstract
Water is essential to sustain life, and availability of safe drinking water is very important. Ground water and surface water are the two main
sources of drinking water in Egypt. Surface water and ground water are
the two main sources of drinking water in Egypt. Although Egypt has the
great Nile River, which is the main resource of water, Egypt depends on
ground water as a secondary resource for drinking water. Ground water is
used for drinking by more than 50% of the people in the world, including
almost everyone who lives in rural areas and to irrigate some agricultural
areas in the Delta region, and in Egypt as an essential source for some
cultivated lands to which the Nile water is not reachable. In many regions
of Egypt, the ground water is widely used for drinking and other domestic
purposes.
