Key Contaminants Detected in Notre Dame
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Notre Dame's Housing Stock?
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Construction dates in Notre Dame center on a median of 1994, and the Census figures behind it describe when homes were built, not what materials they contain.
Most homes in Notre Dame were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.
Source: U.S. Census Bureau ACS B25034.
Protecting Children from Lead in Notre Dame
Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
No safe blood lead level in children has been identified, according to CDC, so an area average under 0.010 mg/L does not rule out exposure at home. In Notre Dame, 17% of homes were built before 1986.

What You Can Do in Notre Dame
- Test your water at home. City-level data shows averages - your tap may differ. Check the certification, price and turnaround time of any water test kit or lab service.
- Install a certified water filter. For Revised Total Coliform Rule, listed in the water-quality records for Notre Dame: if it is a rule or reporting requirement rather than a contaminant, ask your utility what the record involved; for bacteria, follow any boil-water notice from your utility; for a specific chemical contaminant, check whether a filter is certified to reduce it. Not every contaminant has a consumer filter certification.
- Check your home's plumbing. Homes built before 1986 may have lead solder in pipes. A licensed plumber can assess your risk.
- Review your water system's CCR. If you use a community water system, request its annual Consumer Confidence Report for system-level test results or find it online.
