What’s in Cerritos’s water?
Cerritos runs a municipal water system that pulls from the Central Groundwater Basin, supplemented by imported water, to serve this well-planned community near the Orange County line. Because much of the supply is local groundwater, it arrives hard and mineral rich, treated with a disinfectant residual for safety. Residents commonly deal with scale on fixtures, cloudy spots on glassware, and the tight, dry feeling that lingers on skin and hair after a shower. Over time the minerals collect inside water heaters and dishwashers, making them less efficient. PurAgain filtration removes up to 99% of contaminants, giving families cleaner, softer water at every faucet.
The only way to know exactly what’s in your Cerritos water is to test it, and that in-home test is free.
