The United States is on the verge of a national crisis that could mean the end of clean, cheap water.

Hundreds of cities and towns are at risk of sudden and severe shortages, either because available water is not safe to drink or because there simply isn’t enough of it.

The situation has grown so dire the U.S. Office of the Director of National Intelligence now ranks water scarcity as a major threat to national security alongside terrorism.

California Gov. Jerry Brown (D) announced strict new curbs on state water use Wednesday to combat a worsening drought affecting more than 50 million people in the western United States.

The executive order imposes mandatory water reductions across California to reduce water usage by 25 percent.

SACRAMENTO, Calif. -- Reservoirs are running dry, the Capitol's lawn has turned brown, and farmers have left hundreds of thousands of acres unplanted.

Even so, many Californians aren't taking the drought seriously. State water regulators are trying to change that by imposing fines up to $500 a day for wasting water.

The State Water Resources Control Board acted Tuesday amid warnings that conditions could get worse if it doesn't rain this winter.

Devastating Drought Continues to Plague California

                   

California’s Central Valley—prime agricultural land—is being hit the hardest by the state-wide drought which could cause catastrophic losses to crops and food supply.

As California enters its third consecutive dry winter, with no sign of moisture on the horizon, fears are growing over increased wildfire activity, agricultural losses and additional stress placed on already strained water supplies.

The city of Los Angeles has received only 3.6 inches of rain this year—far below its average of 14.91 inches, USA Today reported. And San Francisco is experiencing its driest year since record keeping began in 1849. As of November, the city had only received 3.95 inches of rain since the year began.

Enormous Fire Threatens Water Supply for San Francisco and Parts of East Bay

Hetch Hetchy Aqueduct

eastbayexpress.com - by Robert Gammon - August 23, 2013

The massive Rim Fire is closing in on Hetch Hetchy Reservoir in Yosemite National Park and is threatening the main water supply for the City of San Francisco and numerous other Bay Area communities. As of this morning, the fast-moving blaze was about 2.5 miles from Hetch Hetchy, according to a map created by the US Forest Service. If the enormous fire reaches the tinder-dry forests surrounding the reservoir, it could pollute the freshwater with huge amounts of ash. That’s bad news for San Franciscans and other communities that depend on Hetch Hetchy because the reservoir is not equipped with a water-filtration system.

Desalination Losing Ground as a Solution to California’s Chronic Water Shortage

submitted by Samuel Bendett

Homeland Security News Wire - September 26, 2012

According to the July 2011 census, more than thirty-seven million people live in the state of California, increasing the pressure on the state’s water sources. Desalinating sea water as a solution to the scarcity of fresh water is not a new technology — it has been around for more than four decades — but it has more recently been considered as a way to address California’s chronic, and growing, water shortage.

The Seattle Times reports that the idea has run into problems, and rising construction costs, energy requirements for running desalination plants, and legal challenges have limited desalination in California to only one plant producing drinking water.

Going Grey, and Loving it

Greywater is water from your bathroom sinks, showers, tubs, and washing machines. It is not water that has come into contact with feces, either from the toilet or from washing diapers.

Greywater may contain traces of dirt, food, grease, hair, and certain household cleaning products. While greywater may look “dirty,” it is a safe and even beneficial source of irrigation water in a yard.

Groundwater Depletion in Texas, California Threatens US Food Security

submitted by Samuel Bendett

Groundwater depletion has been most severe in the purple areas indicated on these maps of (A) the High Plains and (B) California's Central Valley. These heavily affected areas are concentrated in parts of the Texas Panhandle, western Kansas, and the Tulare Basin in California's Central Valley. Changes in groundwater levels in (A) are adapted from a 2009 report by the U.S. Geological Survey and in (B) from a 1989 report by the USGS.

Homeland Security News Wire - May 29, 2012

The U.S. food supply may be vulnerable to rapid groundwater depletion from irrigated agriculture; for example, from 2006 to 2009, farmers in the south of California’s Central Valley depleted enough groundwater to fill the U.S. largest man-made reservoir, Lake Mead near Las Vegas — a level of groundwater depletion that is unsustainable at current recharge rates
