JOLIET Lead Service Line Inventory

What you need to know

JOLIET serves approximately 160,000 residents and draws its water from groundwater sources. The utility has not yet published a complete inventory of lead service lines in their system.

Lead service lines are pipes made of lead that carry water from the main water line in the street to your home. If your service line is made of lead, water sitting in that pipe can pick up lead—especially if the water is corrosive or hasn't been used for several hours. Lead exposure is a serious health concern, particularly for children and pregnant people.

What JOLIET has (and hasn't) done

JOLIET has not yet made a public lead service line inventory available. This means:

• You cannot currently search online to find out if your address has a lead service line
• The utility has not reported how many lead, galvanized, or non-lead lines are in the system
• There is no published timeline for completing the inventory

Federal law (the Lead and Copper Rule) requires all water systems to maintain and regularly update an inventory of service lines. JOLIET is required to do this work, though the deadline and current progress are not publicly documented here.

How to find out about your home

Your best option is to contact JOLIET directly. You can:

• Call or visit their office to ask if your service line is lead, galvanized (which can also contain lead), or safe copper/plastic
• Request a copy of their lead service line inventory, even if it's not fully complete
• Ask when they expect to finish cataloging all service lines
• Ask about water testing or line replacement programs

If you're concerned about lead in your water right now, you can have your water tested. The EPA recommends testing if your home was built before 1986 or if you have a lead service line.

Next steps for residents

• Contact JOLIET's water utility directly to ask about your specific address and any available inventory data
• Request their timeline for completing a full lead service line inventory
• Ask about testing programs if you suspect lead in your water
• Reach out to your local health department if you need guidance on testing or have health concerns

Does JOLIET have lead service lines?

JOLIET has not published a complete inventory, so the exact number of lead lines is unknown. Your best source of information is the utility itself—contact them to ask about your address and their current inventory status.

How do I know if my house has a lead service line?

Call JOLIET directly and ask them to check their records for your address. You can also look at your service line if you can access the area where it enters your home—lead is soft, gray, and leaves a mark if you scratch it gently with a coin.

Can I get my water tested for lead in JOLIET?

Yes. Contact JOLIET to ask if they offer free or low-cost testing, or reach out to your local health department for testing options in your area.

When will JOLIET finish its lead service line inventory?

The utility has not published a public timeline. Contact them directly to ask about their schedule and progress on completing the inventory as required by federal law.
