The inhabitants of the Gaza Strip depend heavily on underground resources for their water supplies. This is due, partly, to the scarcity of rain falls in that region and, also, to the limited number (three) of streams and the inadequate quantities of water which can be drawn from them. Chemical analysis of the water (for irrigation and domestic purposes) obtained from several wells and the comparison of the results, with those previously performed, on the same wells, showed, conclusively, that there exist a gradual change in the quality of water attainable from these wells. This has been attributed, to the intrusion of the Mediterranean salty water into the main aquifer (Plio-Pleistocene aquifer) of the area.
