Three thin streams of water fall into a row of steel sinks at Orange County Water District’s Groundwater Replenishment System facility in Fountain Valley: one crystal clear, one slightly yellowed, one a brackish brown-black.
Don’t drink the yellow water, and stay away from the black water. The clear water? Totally fine, even if it tastes a little flat from lack of minerals. And if you live in north or central Orange County, you are already drinking the clear water, with 70 million gallons pumped underground every day as part of the Groundwater Replenishment System.
But soon nearly double that amount will be injected underground thanks to a $143 million expansion.
