Lead Service Lines in Waukegan, IL

Waukegan serves about 115,600 residents across 174 water systems. The city's lead service line inventory status is currently incomplete—data on known lead lines, galvanized pipes, and unknown line materials have not yet been reported to state records.

What you need to know

Lead service lines are pipes that connect your home to the city's water main. If your line is lead, drinking water can pick up lead over time—especially if water sits in pipes overnight or if the water is corrosive. Lead exposure is a real health concern, particularly for young children and pregnant people.

Waukegan's largest water utility is the City of Waukegan system, which serves 87,149 people. Because inventory data isn't yet available, you won't find a public list showing which homes have lead lines. This doesn't mean your water is unsafe—it means the utility hasn't yet published its findings.

How to find out if you have a lead service line

Contact the City of Waukegan Water Department directly. Ask them:

  • Whether your property has a known lead service line
  • If records are incomplete, whether they can inspect your line or send you testing information
  • About water testing kits or sampling programs

The utility can often look this up based on your address and the age of your home. (Homes built before 1986 are higher risk, since federal lead bans in plumbing didn't take effect until that year.)

Testing your water

If you're concerned, you can get your water tested by a certified lab. The EPA recommends testing the first draw of water from your tap (after the water has sat 6+ hours). Some utilities offer free or discounted testing—ask when you call.

If lead is detected, the simplest immediate steps are using a certified filter, flushing your tap before drinking, or using bottled water for drinking and cooking, especially for young children.

Next steps for residents

  • Call the City of Waukegan Water Department with your address and ask about your service line status and testing options
  • Get your water tested by a certified lab if you suspect lead exposure
  • Consult your pediatrician if you have concerns about a child's lead exposure; they can order a blood test if warranted
  • Visit the EPA's lead page for more information on testing, treatment, and health effects
