Is California sitting on the solution to its drought?

Researchers believe there's more water under California than previously thought. The state is in the fifth year of a drought.

Californians: A solution to the drought may be under your feet, according to a study from Stanford scientists.

Thousands of feet beneath the surface of the state’s Central Valley, one of the world’s biggest agricultural hubs, there may be up to 2,700 cubic kilometers of usable groundwater — nearly three times more than the amount previously thought.

“It’s not often that you find a ‘water windfall,’ but we just did,” said study co-author Robert Jackson, a professor at Stanford. “There’s far more fresh water and usable water than we expected.”

Another one of the study’s authors said the findings would be relevant in other places where there are water shortages — including Texas, China and Australia.

California is in the fifth year of a major drought, according to state officials. State and local authorities have imposed strict regulations in an effort to conserve water, while also levying fines on violators to enforce conservation efforts.

The drought has affected much of the country, as California grows more than a third of America’s vegetables and two-thirds of its fruit and nuts.

Farmers have already started looking to underground springs to feed their crops, so the windfall may be welcome news.

The dangers

The discovery is not a panacea, however.

Drilling for water so deep is expensive and can be hazardous.

It may add to the gradual sinking of the land already taking place in the Central Valley, according to a statement from Stanford.

“Groundwater pumping from shallow aquifers has already caused some regions to drop by tens of feet,” the researchers said.

Those deep groundwater resources are also vulnerable to contamination from oil and gas — oil and gas drilling occurs in up to 30% of the sites where deep groundwater is located — as well as from other human activities, like hydraulic fracturing, according to the study.

“We might need to use this water in a decade, so it’s definitely worth protecting,” said Mary Kang, another one of the study’s co-authors.

Still, Kang and Jackson believe that just because fracking has occurred, it doesn’t mean the water has been ruined.

“What we are saying is that no one is monitoring deep aquifers,” Kang said. “No one’s following them through time to see how and if the water quality is changing.”

    This is horribly stupid, if the central valley is already sinking why on earth would you remove more ground water? Israel has NO fresh water and no allies nearby to get water from. They use desalinization and it has worked great for a long time. STOP trying to take the cheap way out.

      Not only that, Metal but when you deplete that water, the soil compresses and the land sinks. For pete’s sake they just ran the story of Beijing having this happen. Too many people for the land/water to sustain.
