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
Properties of water the bottom of frozen-over fresh water lakes and rivers. As the surface of salt water begins to freeze (at −1.9 °C for normal salinity seawater, 3.5%) the ice that forms is essentially salt-free, with about the same density as freshwater ice. This ice floats on the surface, and the salt that is "frozen out" adds to the salinity and density of the sea water just below it, in a process known as "brine rejection". This denser salt water sinks by convection and the replacing seawater is subject to the same process. This produces essentially freshwater ice at −1.9 °C on
