Lead Service Lines in St Paul, MN

What you need to know

St Paul's water system serves about 445,541 people through 75 different water utilities. The largest, Saint Paul Regional Water Services, supplies water to roughly 392,529 residents.

Lead gets into water through service lines—the pipes that connect the public water main to your home. If your home was built before 1986, there's a higher chance your service line contains lead. Even homes built later can have lead-bearing components.

The good news: St Paul utilities have not reported confirmed lead service lines in their inventories so far. However, this doesn't mean lead pipes don't exist in the city. Many utilities are still in the process of mapping their service lines, and incomplete records are common nationwide.

Why this matters

Lead exposure, even at low levels, can affect children's development and learning. Adults can experience high blood pressure and kidney damage. There is no safe level of lead in drinking water.

If your home is older or you're concerned about your water, testing is the most direct way to know what you're drinking. Testing is inexpensive (usually $20–$50) and available through your local health department or a certified lab.

What St Paul utilities are doing

Water systems are required by the EPA to develop and maintain lead service line inventories. Saint Paul Regional Water Services and other utilities in the area have inventories on file, though some may still be incomplete as communities finish their mapping work.

You can contact your utility directly to ask:

  • Whether your address has a known lead service line
  • If your service line status is still "unknown"
  • What water testing options they recommend

How to find your water utility

Most St Paul residents get water from Saint Paul Regional Water Services, but some areas are served by smaller systems. If you're unsure which utility serves your address, call your city's water department or check your water bill.

Next steps for residents

  • Contact your water utility to ask about your service line status and get the results of any water tests they've conducted
  • Test your water if you want to know lead levels in your home—your utility or health department can direct you to a certified lab
  • Know your home's age: if it was built before 1986, assume lead risk is higher until proven otherwise
  • Use a certified lead filter (NSF/ANSI 53) on your tap if you're concerned, while you investigate your service line

Common questions

Does St Paul have lead in the water?

St Paul utilities have not reported confirmed lead service lines in their inventories. However, inventories may not be complete, and older homes are at higher risk. Testing your water at home is the most direct way to know your exposure.

How do I find out if I have a lead service line?

Contact Saint Paul Regional Water Services or your local water utility with your address. They can tell you if your service line is known to contain lead, galvanized, or still unknown. You can also request a water test to check lead levels in your home.

What should I do if my water tests positive for lead?

Use only cold tap water for drinking and cooking (hot water can leach more lead). Consider installing an NSF/ANSI 53 certified filter, and call your water utility and doctor for guidance. If you have young children, contact your pediatrician.

When was my house built and why does it matter?

Homes built before 1986 are more likely to have lead service lines or lead solder. If you don't know your home's age, check your property records or ask a real estate agent. Older homes should be tested regardless of what the utility says about the service line.
