A new nationwide study has unearthed the huge hidden potential of tapping into salty aquifers as a way to relieve the growing pressure on freshwater supplies across the United States.×458&w=550&h=458&adk=2458254856&raru=1&bc=1&pv=2&vis=1&wgl=1&asnt=0-14763460143825615402&dff=Arial%2C%20Helvetica%2C%20sans-serif&is_amp=3&amp_v=1493855940942&d_imp=1&dt=1494169618953&ifi=1&adf=730195093&c=448031009825&output=html&nhd=0&iu=8730621137&eid=117152671%2C2088462&biw=1024&bih=647&adx=237&ady=322&u_aw=1024&u_ah=768&u_cd=32&u_w=1024&u_h=768&u_tz=600&u_his=1&oid=2&brdim=0%2C0%2C0%2C0%2C1024%2C0%2C1024%2C647%2C1024%2C647&isw=1024&ish=647&pfx=0& into data from the country’s 60 major aquifers, the U.S. Geological Survey reports that the amount of brackish – or slightly salty –  is more than 35 times the amount of fresh groundwater used in the United States each year.Supplies exist in every state except New Hampshire and Rhode Island, with the largest reserves in the central U.S. In the Golden State, the California Coastal Basin and Central Valley aquifers together contain close to 7 billion acre-feet of brackish , which if desalinated could provide enough water for the state’s needs for the next 160 years.
