Lead Levels in ZIP 53565

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

Lead Level: 37.0 ppb — EXCEEDS EPA Action Level

The 90th percentile lead level in 53565 is 37.0 ppb, which EXCEEDS the EPA action level of 15 ppb. This is a serious concern. The water utility is legally required to notify residents, identify the source of contamination, and take corrective action. Do not give this water to infants, children, or pregnant women without first passing it through a certified NSF/ANSI 53 water filter. Contact Mineral Point Waterworks immediately for current guidance, or call the EPA Safe Drinking Water Hotline at 1-800-426-4791.

Lead exposure risk in 53565 is rated High. EPA models estimate a 70% 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.

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.
