Lead Levels in ZIP 64158

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

Lead Level: 2.1 ppb — Very Low

The 90th percentile lead level in 64158 is 2.1 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 exposure risk in 64158 is rated Low. EPA models estimate a 19% probability of lead exposure risk in this ZIP code based on housing age, infrastructure age, and water system data. This rating reflects newer infrastructure, lower housing age, and/or low detected lead levels. Standard precautions — flushing taps before use, using filtered water for infants — are still recommended.
