Lead Levels in ZIP 48097

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

Lead Level: 7.0 ppb — Below Action Level

The 90th percentile lead level in 48097 is 7.0 ppb, below the EPA action level of 15 ppb but above what many health experts consider ideal. The CDC and EPA both affirm there is no safe level of lead exposure for children. Families with young children or pregnant women should consider a certified NSF/ANSI 53 water filter, and request lead testing of their home's tap water.

Lead exposure risk in 48097 is rated High. EPA models estimate a 61% 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.
