According to Jay Famiglietti, senior water scientist at he NASA Jet Propulsion Laboratory, California has only a year to go before water from its reservoirs gets totally depleted.
Citing NASA data, Famiglietti said the state’s water supply has been declining steadily since 2002, the year it began monitoring its water supply with satellites.
Not only has water been heavily used for farming and landscaping purposes, among other things, but drought has also contributed immensely to its shrinking groundwater supply.
Famiglietti’s has called for an immediate rationing of water, including for domestic, municipal, agricultural and industrial uses.
He said the public needs to become more involved with setting priorities for water usage. “Water is our most important, commonly owned resource, but the public remains detached from discussions and decisions.”
Other than rationing what will really ensure continuous water supply is the construction of desalination plants.
San Diego is said to be building the largest ocean desalination plant in the Western Hemisphere.
The $1-billion project will deliver 50 million gallons of drinking water a day and is scheduled to open in 2016.
California had the driest January this year since record-keeping began in 1895, with groundwater and snowpack levels at all-time lows.
Californians use an average of 181 gallons of water each day and a total of around 2.5 trillion gallons a year.
