What’s in West Covina’s water?

Set against the South Hills in the eastern San Gabriel Valley, West Covina receives a blend of Main San Gabriel Basin groundwater and imported water drawn from the Colorado River and Northern California. Both sources arrive hard, and the imported share is treated with chloramine, a combination that produces persistent scale and a mild chemical taste. Homeowners across the city notice mineral spots on glassware, buildup around fixtures, and hair that feels rougher than it should. Over time that scale quietly damages dishwashers, water heaters, and coffee makers. A PurAgain system strips out up to 99% of these contaminants, delivering soft, clean water that is easier on every appliance in the house.

The only way to know exactly what’s in your West Covina water is to test it, and that in-home test is free.
