Lead Levels in ZIP 65673

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

Lead Level: 1.0 ppb — Very Low

The 90th percentile lead level in 65673 is 1.0 ppb, well below the EPA action level of 15 ppb. While this is a reassuring result, the EPA's public health goal for lead is actually zero — no amount of lead is considered completely safe, particularly for children under 6 and pregnant women. Running your tap for 30 seconds before use and using a certified NSF/ANSI 53 filter adds an extra layer of protection.
Lead Level (90th percentile)
1.00 ppb (0.001 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.
