The quickest way to find out whether your Chicago home has a lead service line is to look up your address in the city’s Service Line Inventory, then confirm it by checking the pipe where water enters your basement and ordering a free lead test through 311. Chicago has an estimated 412,000 lead service lines, more than any other U.S. city, so if you live in an older building it is worth the 15 minutes.
A lead service line is the underground pipe that carries water from the city main under the street into your building. Part runs under the public way and part on your property, and the whole line counts as lead if any section is lead.
That is different from lead in household plumbing, such as old solder or brass fixtures, which can exist with or without a lead service line.
The reason Chicago has so many is simple: the city’s plumbing code required them until the 1986 federal ban. The city adds a phosphate to the water that coats the inside of lead pipes and reduces how much lead leaches out. Street work, main replacements and meter installations can disturb that coating, which is why the city’s advice centers on testing and flushing.
What tends to get overlooked is that a lead line does not mean lead at your tap every day. Between 2016 and 2022, Chicago tested water from more than 30,000 homes, and about 6% came back at or above the federal action level of 15 parts per billion, according to ABC7 Chicago’s reporting on the city’s data. You only know what your own tap is doing by testing it.
If I were checking a Chicago address from scratch, I would do these four steps in order. All four are free.
The Chicago Department of Water Management publishes a Service Line Inventory that lists the known or presumed material for every service line in the city. Results fall into four categories:
Two cautions: the inventory submitted to Illinois EPA in April 2025 will not show every later replacement, and larger buildings are sometimes listed under the nearest intersection.
In most Chicago houses and two-flats, the service line comes through the basement wall facing the street and runs to a shutoff valve. Check the stretch between the wall and that valve.
Gently scrape the pipe with a key or coin (do not dig into it), then hold a refrigerator magnet against it.
| Pipe material | Color before scratching | After a light scratch | Magnet sticks? |
|---|---|---|---|
| Lead | Dull gray | Shiny silver | No |
| Galvanized steel | Dull gray | Stays dull gray | Yes |
| Copper | Brown, like a penny | Bright copper | No |
| Plastic | White, black or blue | No change | No |
This only identifies the visible section. The pipe under your yard or parkway can be different, so copper in the basement does not rule out lead outside.
Chicago provides free lead test kits. Request one online at chicagowaterquality.org or call 311, and the city arranges pickup of your samples. You can also request a technician visit through 311 (no water use for six hours beforehand, and someone must be home).
The practical question is how to reduce exposure until the pipe is replaced. Chicago’s guidance comes down to three habits and one longer-term step.
If you have young children, ask your pediatrician about a blood lead test, the only way to know whether a child has been exposed.
One thing I would not wait on is the replacement deadline. Chicago’s current plan runs to 2076, so for many households these habits will matter for years.
Renters can do every check above except order the replacement. Look up the address, request a 311 test kit and share the results with your landlord, who decides on the pipe. Many leases rule out under-sink filters, leaving a pitcher, bottled water or delivery.
The way I think about it, the pipe and your drinking water are two separate decisions. The pipe can take years. Your drinking water is something you can settle this week.
Verde Springs water does not pass through your building’s service line. It starts from carefully selected municipal sources and goes through activated carbon, reverse osmosis, UV treatment, fine filtration and ozone disinfection, with continuous monitoring. Verde Springs delivers it in reusable 3-gallon glass or 5-gallon plastic bottles, brought up to the unit, with no contract. You would still cook with tap water, so the flushing and filter advice still applies.
