What’s in Rancho Cucamonga’s water?

Water for Rancho Cucamonga is delivered by the Cucamonga Valley Water District, which combines local groundwater with imported supply to serve homes along the foothills of the San Gabriel Mountains. Sitting just below Mount Baldy, the community draws much of its water from basins recharged by mountain runoff, and that source is naturally hard and full of dissolved minerals. Add the chlorine used for disinfection and you get water that tastes different from town to town and leaves its mark on everything it touches. Families here regularly battle white scale on fixtures, cloudy glassware, and dry skin after showering. A PurAgain system removes up to 99% of these contaminants, so your household enjoys softer, cleaner, better tasting water day after day.

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