What’s in San Luis Rey’s water?

The San Luis Rey community sits in the historic river valley of the same name on Oceanside's inland edge, where homes receive City of Oceanside water blending desalted local groundwater with imported regional supply. Groundwater pulled from the valley basin tends to carry extra dissolved minerals, which keeps the tap water here on the hard side and often gives it a distinct mineral taste. Families notice scale rings inside kettles, spotting on freshly washed glasses, and skin that feels dry after showering. Left untreated, those minerals accumulate in plumbing and appliances year after year. A PurAgain system removes up to 99% of contaminants, delivering cleaner, softer water that is gentler on both your home and your family.

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