"Groundwater management has several advantages over other methods. It is generally cheaper than building dams or desalinating water. What's more, aquifers lose no water through evaporation, do not flood ecosystems, and in California they have capacity for between 17 and 26 times as much water as all of the state's reservoirs combined."

I've been saying this for years. When you watch the runoff from rain flow down the streets and end up in the ocean you know what a waste it is. It's a win,win idea.

Recharge pools could help quench future California droughts - environment - 14 May 2015 - New Scientist
 
Do you know if ground water purity is affected?
 
California has been using underground reservoirs for years.
 
First, you have to have enough water to recharge the pools. California probably leads the nation is water conservation, but, again, you have to have something to conserve.

There is plenty of run off that gets wasted by going into the ocean even from small rain storms.
 
While there can be efforts made to salvage some of that water, you might consider that even a major rainstorm only drops about 4" of water. And most drop from a trace to 1". 1" is not much in a major aquifer and the draw down by agriculteral wells would quickly deplete that.
