Groundwater 101

What is Groundwater?

Groundwater is the water that is stored underground. Groundwater fills the spaces between soil particles like sands and gravels. The Chino Groundwater Basin is one of the largest groundwater basins in southern California. We rely on water from the Chino Groundwater Basin for over half of the water that we drink and use in our homes and outside in our yards.
