COLUMBUS PUBLIC WATER SYSTEM: Lead Service Line Information
Columbus Public Water System serves about 1.3 million people across Ohio's capital region. Like water systems nationwide, the utility is required by federal law to inventory lead service lines—the pipes that may connect your home to the main water line underground.
What you need to know right now
A lead service line is a potential source of lead in drinking water. If your home was built before the 1980s, there's a higher chance your connection uses lead or galvanized steel (which can also leach lead). The only way to know for sure is to check your water system's inventory or contact the utility directly.
Columbus Public Water System has not yet published its complete lead service line inventory online. This means the data about how many lead lines serve the system—and where they're located—isn't publicly available yet. Federal rules require water systems to complete full inventories and make them accessible to customers.
Why this matters
Lead exposure, especially for children and pregnant people, can affect brain development and learning. The CDC recommends testing your home's water if you're concerned. Even low levels of lead can pose risks over time.
The good news: lead is removable from water through certified filters and other treatment methods, and lead service lines can be replaced. Many states and the federal government are now funding these replacements.
What Columbus Public Water System should have
Under federal Lead and Copper Rule requirements, your utility should maintain:
- A complete inventory of all lead and galvanized service lines
- A plan and timeline for replacing lead lines
- Public access to this information
Your utility may be in the process of gathering this data or updating their website. It's worth asking directly.

Frequently asked
How do I know if my house has a lead service line in Columbus?
Contact Columbus Public Water System's customer service to ask about your specific address. You can also hire a plumber to inspect the line where it enters your home, though a definitive answer usually requires the utility's records.
Is lead in Columbus water dangerous?
Lead in drinking water is a health concern, especially for children and pregnant people. The CDC recommends testing your water if you suspect lead exposure. Even low levels can be harmful over time, so it's worth taking steps to reduce it.
Can I get my lead service line replaced for free?
Many utilities now offer partial or full funding for lead line replacement through federal Infrastructure Investment and Jobs Act (IIJA) funding or state programs. Contact Columbus Public Water System to ask what programs you may qualify for.
What should I do right now if I'm worried about lead in my tap water?
You can use a certified water filter (NSF 53 certified reduces lead), flush your tap before drinking, and request a water test through your utility or a certified lab. Talk to your pediatrician if you have health concerns about past exposure.
