Is Sierra Vista Tap Water Safe to Drink?
Read that carefully, because "above a health goal" is the phrase people misread. For many substances the goal is zero, so it can mean "found at all" rather than "too much" — the number that matters is the distance to the enforceable limit, and the table below shows both. Where a finding warrants it, match a certified filter to that contaminant rather than to a "removes 99%" claim.
The data below shows test results from 7 water utilities serving 58,109 people in the Sierra Vista area. Water quality testing is conducted regularly and reported to the EPA. This report was last updated 2024-10-22.
