Lead Levels in ZIP 77429

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

Lead Level: 1.5 ppb — Very Low

The 90th percentile lead level in 77429 is 1.5 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 77429 is rated Low. EPA models estimate a 16% 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.

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.
