Lead Service Lines in Decatur, IL

What we know about lead in Decatur's water systems

Decatur and the surrounding area are served by 8 public water systems that together reach about 85,666 people. The largest is the City of Decatur system, which supplies water to roughly 76,122 residents.

Lead enters drinking water primarily through lead service lines—the pipes that connect the water main under the street to homes. These lines were commonly installed before 1986, when federal regulations restricted their use. Whether your home has a lead service line depends on when it was built and where you live within the city.

Currently, no lead service lines have been identified in Decatur's inventories. However, the absence of reported cases does not mean there are none; many water systems are still in the early stages of mapping their infrastructure. Some homes may have galvanized steel pipes (which can corrode and release lead) or unknown pipe materials that require further investigation.

How to find out what's in your home

Your water utility maintains records of service line materials, though these records can be incomplete. Start by contacting your local water system—the City of Decatur system serves most residents, but verify which utility serves your address first.

Ask specifically:

• What material is the service line to my property?
• Do you have records for my address, or is it listed as unknown?
• If unknown, how can I get my line tested or identified?

If your utility cannot confirm your service line is lead-free, you may want to have it tested. A water quality test can detect lead levels in your tap water. You can also request a simple visual inspection of the line where it enters your home (though this doesn't always reveal the full picture).

Why this matters

Lead exposure, especially for children under 6, can affect brain development and learning. Even small amounts matter. If you have young children or are pregnant, this is worth investigating promptly.

The CDC recommends that anyone with a potential lead service line flush their taps before drinking or cooking with tap water, and consider using a water filter certified to remove lead while you gather more information.

Next steps for residents

• Contact your water utility to ask about your service line material. Use the system name that serves your address.
• Request your service line record or schedule an inspection if records are unavailable.
• Get your water tested if you're concerned; your utility or a local health department can guide you.
• Talk to your doctor if anyone in your household—especially children under 6—may have been exposed.
