Dead Sea 342 parts per thousand (in 2002), and a temperature that swung between and . Underneath a zone of transition, the lowest level of the Dead Sea had waters of a consistent temperature and complete saturation of sodium chloride (NaCl). Since the water near the bottom is saturated, the salt precipitates out of solution onto the sea floor. Beginning in the 1960s, water inflow to the Dead Sea from the Jordan River was reduced as a result of large-scale irrigation and generally low rainfall. By 1975, the upper water layer was saltier than the lower layer. Nevertheless, the upper layer remained
Red Sea–Dead Sea Water Conveyance used by Jordan and the Palestinians. Concerns regarding Israel's nuclear facility are irrelevant as the Dimona reactor is cooled by heavy, not normal (i.e., light) water. Under the current proposal, water sufficient only to prevent the Dead Sea from dehydrating will flow through the system, preventing salt water flow into wells. The World Bank study recommended re-routing the conduit to avoid the geological faults of the Araba Valley. Red Sea–Dead Sea Water Conveyance The Red Sea–Dead Sea Conveyance, sometimes called the Two Seas Canal, is a planned pipeline that runs from the coastal city of Aqaba by the Red Sea
