Arlington Heights Lead Service Line Inventory
What is a lead service line?
A lead service line is the underground pipe that connects your home to the public water main in the street. If your home was built before the 1980s, there's a meaningful chance your service line contains lead—a toxic metal that can leach into drinking water, especially in homes with acidic water or after the water sits unused for hours.
The Village of Arlington Heights serves about 73,320 people across Illinois. Like all US water utilities, Arlington Heights is required to maintain an inventory of lead service lines in their system and work toward replacing them.
What's the status in Arlington Heights?
As of our last update, Arlington Heights has not yet completed a full inventory of lead service lines in its system. This doesn't mean there's no lead—it means the count is still being determined. Your utility is in the early stages of mapping the pipes they own and have direct information about.
The best way to learn your own home's status is to contact the Village of Arlington Heights directly. They can tell you whether your specific service line is documented as lead, non-lead, or unknown based on records, age, or previous testing.
What can you do right now?
Test your water. A simple, inexpensive test can detect lead levels in the water coming from your tap. If results are elevated, the Village can advise on treatment options or replacement timelines.
Check your home's age and pipes. Homes built before 1986 are more likely to have lead service lines. If you can see your pipes in the basement or crawl space, a plumber can help identify the material.
Ask your utility for your service line status. Contact the Village of Arlington Heights water department and ask whether they have records of your line's material. They may have historical documentation, even if the full inventory isn't complete yet.
If you have young children or are pregnant, the CDC recommends being extra cautious. Talk to your pediatrician or local health department about your water and whether testing or temporary measures make sense for your household.

Frequently asked
Does Arlington Heights have lead in the water?
Whether lead is present depends on your specific service line. Arlington Heights is still inventorying its lead service lines. Contact the utility directly with your address to find out if your line is documented as lead or non-lead, and consider getting your water tested.
How do I know if my service line is lead?
Call the Village of Arlington Heights water department and provide your address—they can check their records. You can also have a plumber inspect pipes in your basement or crawlspace, or get your water tested for lead.
Is it safe to drink water from a lead service line?
Lead is most risky for young children and pregnant people. If you have a lead line, the CDC recommends letting water run for 30 seconds before use and flushing fixtures in the morning. A water test will show your actual lead levels; ask your doctor if you're concerned about health.
When will Arlington Heights replace lead service lines?
Contact the Village directly to ask about their replacement schedule and any programs available to homeowners. Timelines vary based on funding and inventory progress.
