"Too Much Salt: Water Desalination Plants Harm Environment: U.N."

"OSLO - Almost 16,000 desalination plants worldwide produce bigger-than-expected flows of highly salty waste water and toxic chemicals that are damaging the environment, a U.N.-backed study said on Monday.

Desalination plants pump out 142 million cubic meters (5 billion cubic feet) of salty brine every day, 50 percent more than previous estimates, to produce 95 million cubic meters of fresh water, the study said.

About 55 percent of the brine is produced in desalination plants processing seawater in Saudi Arabia, the United Arab Emirates and Qatar, according to the study by the U.N. University’s Canadian-based Institute for Water, Environment and Health (UNU-INWEH)."
