Lead Levels in ZIP 82002

EPA action level: 15 ppb | Public health goal: 0 ppb

Lead Level: 15.0 ppb — Approaching Action Level

The 90th percentile lead level in 82002 is 15.0 ppb, approaching the EPA action level of 15 ppb. When a water system's 90th percentile exceeds this threshold, the utility is required to take corrective action including public notification and infrastructure upgrades. Residents — especially those with children or in homes built before 1986 — should use a certified lead-reducing filter (NSF/ANSI 53 or 58) for drinking and cooking water.
Lead Level (90th percentile)
15.00 ppb (0.015 mg/L)
Lead Exposure Risk Rating
Unknown
Note: Lead levels above are the 90th percentile from EPA monitoring — meaning 90% of samples were at or below this level. Even "undetected" tap water lead doesn't account for lead leaching from home plumbing. If your home was built before 1986, individual tap testing is recommended.
