Lead Service Lines in St. Peters, Missouri
What is a lead service line?
A lead service line is the pipe that connects your home's water meter to the water main buried under the street. If your home was built before 1986, there's a chance this pipe is made of lead. When lead pipes carry drinking water, lead can dissolve into the water—especially if the water is corrosive or sits in the pipes for hours.
Lead in drinking water is a real health concern, particularly for young children and pregnant people. Even small amounts of lead exposure can affect brain development and learning in kids.
What we know about St. Peters
St. Peters Public Water Supply serves about 52,575 people in Missouri. Like many water utilities across the US, St. Peters is required by federal law to create and maintain an inventory of lead service lines in its system.
As of now, St. Peters has not yet published a complete inventory. This doesn't mean there are no lead service lines—it means the utility is still in the process of identifying and documenting them.
Why the inventory matters
The Lead and Copper Rule, updated in 2021, requires all public water systems to map out their lead service lines by October 2024. This information helps:
- Homeowners and renters know if their property is at risk
- The utility plan replacement projects and prioritize high-risk areas
- Public health officials track progress on removing lead from drinking water
What you can do right now
Even without a published inventory, you don't have to wait to take action.
Find out if your home has a lead service line. Contact St. Peters Public Water Supply and ask them directly about your address. Many utilities can tell you based on your home's age, construction records, or previous water quality testing.
Test your water. If you're concerned about lead, a simple water test can tell you if it's present. Your utility can advise you on low-cost or free testing options.
Use a filter if needed. NSF-certified filters designed for lead can reduce levels while you investigate further. Your pediatrician or the CDC website has guidance on protecting young children.

Frequently asked
How do I know if my house has a lead service line?
The best way is to contact St. Peters Public Water Supply directly and ask for your address. They may have records based on your home's age or construction date. You can also have a plumber inspect the pipe where it enters your house—lead is soft, gray, and can be scratched with a coin.
Is lead in water dangerous for kids?
Yes. Lead exposure affects brain development and can impact learning and behavior in young children, even at low levels. Talk to your pediatrician about your water and home, and visit the CDC website for guidance on reducing exposure.
Can I remove lead from my tap water?
Point-of-use filters certified by NSF for lead reduction can help. Some utilities also offer free or low-cost testing and treatment options. Contact St. Peters PWS to ask what they recommend for your situation.
