What solution is Santa Clara County using to recharge their aquifers?
surface water

Can aquifers be replenished?
Aquifers can be replenished artificially. For example, large volumes of ground water used for air conditioning are returned to aquifers through recharge wells on Long Island, New York.
How does underground water get replenished?
Groundwater supplies are replenished, or recharged, by rain and snow melt that seeps down into the cracks and crevices beneath the land’s surface. In some areas of the world, people face serious water shortages because groundwater is used faster than it is naturally replenished.
