What’s in Coronado’s water?
Coronado, in San Diego County, relies on roughly 85% imported, chloramine-treated water, leaving a persistent chlorine taste and mineral hardness that builds up on your fixtures and inside your plumbing and appliances.
A Puragain Water system removes up to 99% of those contaminants — chlorine, hardness minerals, lead, PFAS and more — so the water your family drinks, cooks with, and showers in is genuinely clean. The only way to know what’s in yours is to test it, and that test is free.
