Cities May Completely Run Out Of Water Sooner Than You Think (Huff Post)

  • San Francisco Bay Area, California
    Unsurprisingly, much of California was shown to be at high risk for water shortage by Columbia University's recent study and the same region's watersheds were also stressed, according to CIRES. As the Bay Area continues to boom, there just may not be enough water for the future population of the region, according to a recent report from area non-profit group SPUR. SPUR reports that due to climate change, rising sea levels and earthquakes the region's water could be severely disrupted, reduced or even infiltrated by sea water. In 2010, the NRDC said that San Francisco and other regional cities in the Bay Area like San Jose and Oakland are "very likely" to experience a crisis due to water shortage within the next 50 years, according to 24/7 Wall St. San Francisco estimated population: 825,863 (San Francisco, 14th most populous city in the U.S.), Bay Area metro: 8,370,967 (5th most populous in U.S.)

    Los Angeles, California
    Columbia University's water scarcity study showed most of California, from San Diego all the way to Santa Barbara, at high risk for water problems. And CIRES' study showed much of the same areas with high to moderate stress on regional watersheds from the coast and all the way inland. Los Angeles relies on importing much of its water from the Colorado River system which has long provided the American West with water -- seven states in all that are home to almost 40 million people. But demands on the river are often cited as unsustainable, due to predicted population increases and climate change. A recent report from the U.S. Bureau of Reclamation predicts a water supply and demand gap in the Colorado River of about 3.2 million-acre feet by 2060 -- roughly five times the amount of water that Los Angeles uses in a year. L.A. was listed as the top American city running out of water by 24/7 Wall St. due to increasing population and drought as the city continues to increase water demands which are believed to be unsustainable. The Los Angeles-Long Beach-Santa Ana region of Southern California was ranked as 6th most at-risk city for water vulnerability issues, by University of Florida in 2012. Estimated population: 3,857,799 (2nd most populous city in the U.S.), metro: 16,400,000 (2nd most populous in U.S.).
