Arab–Israeli peace projects regional problems of acute shortage of clean fresh water in Jordan, and the rapid contraction of the Dead Sea. A new desalination plant to be built near the Jordanian tourist resort of Aqaba would convert salt water from the Red Sea into fresh water for use in southern Israel and southern Jordan; each region would get eight billion to 13 billion gallons a year. This process would produces about as much brine as a waste product; the brine would be piped more than 100 miles to help replenish the Dead Sea, already known for its high salt content. This would
Salt been laid down over the millennia from the evaporation of seas and lakes. These are either mined directly, producing rock salt, or are extracted in solution by pumping water into the deposit. In either case, the salt may be purified by mechanical evaporation of brine. Traditionally, this was done in shallow open pans which were heated to increase the rate of evaporation. More recently, the process is performed in pans under vacuum. The raw salt is refined to purify it and improve its storage and handling characteristics. This usually involves recrystallization during which a brine solution is treated with chemicals
