What’s in Tustin’s water?

Tustin, recognizable by the towering former Marine base blimp hangars, supplies its residents through a city water system that combines Orange County groundwater with imported water from Metropolitan's Colorado River and State Water Project sources. The imported component brings noticeable hardness, and even the local basin water carries enough dissolved mineral to leave its mark. Around town, that means scale accumulating in water heaters, spots on rinsed dishes, and a filmy feel after a shower. Chloramine disinfection adds a taste that many Tustin families would rather not have in their morning coffee. With a PurAgain filtration and conditioning system removing up to 99% of contaminants, your water finally feels and tastes the way it should.

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