What’s in San Ysidro’s water?

Right at the international border, San Ysidro is served by the Otay Water District, which buys treated and desalinated water from the San Diego County Water Authority to supply this southernmost corner of the county. That water leans on imported Colorado River and Northern California sources, so it reaches local homes carrying a heavy mineral load and disinfectant taste. Residents commonly notice hard-water spots on dishes, scale creeping over faucets, and skin and hair left dry after bathing. Those minerals also settle inside water heaters and washing machines, quietly driving up repair and energy costs. A PurAgain system filters the supply as it enters the home and removes up to 99% of contaminants, giving families noticeably cleaner and softer water.

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