Water Supply Crisis Facing 36 States

"At least 36 states are expected to face water shortages within the next five years, according to U.S. government estimates. Available freshwater supplies are dwindling across the country due to rising temperatures and droughts, while increasing sprawl, population and inefficient resource usage are leading to rising demand.

Rising temperatures due to global warming have increased evaporation rates across the country and reduced the availability of important water sources. One of these is the Sierra Nevada snowpack, which supplies a significant portion of California's water. Across the West, similar trends are expected to reduce flows of the Colorado River, which supplies water for seven states.

Meanwhile, rising sea levels are expected to cause saltwater to infiltrate freshwater aquifers in coastal states, rendering that water unusable.

Other threatened regions include the Midwest, where the Great Lakes are shrinking, and upstate New York, where reservoir levels have fallen to record lows. Georgia's crisis has already arrived, and Florida's is expected to hit soon."
