Lead Levels in ZIP 70076

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

Lead Data Not Available

Lead testing data was not found in EPA records for ZIP code 70076. This may occur with very small systems or systems that report under a parent utility. Contact GRAMERCY WATERWORKS directly to request lead testing results or a copy of their Consumer Confidence Report.

Lead exposure risk in 70076 is rated High. EPA models estimate a 65% probability of lead exposure risk in this ZIP code based on housing age, infrastructure age, and water system data. This typically reflects older housing stock built before 1986 (when lead pipes were banned), aging distribution infrastructure, or detected lead levels in water samples. Families should prioritize getting their tap water tested independently and installing a certified lead-reducing filter.

Lead Exposure Risk Rating

Lead Exposure Probability

EPA model estimate based on housing age and infrastructure

65%
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.
