What's in Milwaukee's Water?

Milwaukee's drinking water comes from Milwaukee Water Works, which serves the metro area's 1,600,000 residents. While the utility meets most federal EPA standards, meeting the minimum legal requirement doesn't always mean the water is as clean as you'd want for your family.

Why lead Matters

Lead exposure is especially dangerous for children under 6. Even low levels can cause developmental delays, learning difficulties, and behavioral problems. There is no safe level of lead exposure for children.

This is especially important for families with young children, pregnant women, or anyone with a compromised immune system. Children absorb contaminants at higher rates than adults, and their developing bodies are more vulnerable to the effects.

Check Your Specific Address

Water quality can vary within Milwaukee depending on which part of the distribution system serves your home, the age of your pipes, and whether you have lead service lines. I recommend two steps:

  1. Use our free Water Quality Lookup tool - Enter your ZIP code here to check EPA violation records for your specific area.
  2. Test your tap water - A home water test kit like Tap Score ($150-200) will tell you exactly what's in the water coming out of your faucet, which can be different from what the utility reports.
