HAMILTON PUBLIC WATER SYSTEM Lead Service Line Inventory
What you need to know
Hamilton Public Water System serves about 62,447 people in Ohio. Like all U.S. water utilities, it is required by federal law to identify and inventory lead service lines — the pipes that may connect your home to the main water line.
Current status: Hamilton has not yet completed and published a public lead service line inventory. This does not mean there are no lead lines in the system; it means the utility is still working through the process of locating and cataloging them.
Why this matters
Lead service lines are a real health concern, especially for young children and pregnant people. Even small amounts of lead in drinking water can affect development. If your home was built before the 1980s, there is a higher chance your service line contains lead, since lead pipes were commonly used before the federal ban in 1986.
The good news: lead in water is preventable through simple steps like flushing your tap and using filters. The EPA and CDC have clear guidance on reducing exposure.
What Hamilton should be doing
Federal law requires water utilities to:
- Test water at customers' taps to measure lead levels
- Create a complete inventory of service lines and share it publicly
- Develop a plan to replace lead lines over time, prioritizing high-risk homes
Hamilton is in the process of meeting these requirements. The timeline and details vary by utility.
Next steps for residents
- Contact Hamilton Public Water System directly to ask about the status of their lead service line inventory and whether your address has been assessed.
- Request a free water test from your utility; many offer this at no cost.
- Consider a point-of-use filter certified for lead reduction (NSF Standard 53) while you wait for inventory results. These are inexpensive and effective.
- Check the CDC's guide on lead in drinking water for more information about testing your home and reducing exposure.

Frequently asked
Does Hamilton Public Water System have lead in the water?
The system has not yet published a public inventory, so the full extent is unknown. However, lead service lines can exist in older homes even if the water itself tests clean at the treatment plant. Contact your utility or request a free tap water test to know your home's status.
Is it safe to drink tap water from Hamilton?
Hamilton must follow EPA safety standards for water quality. If you're concerned about lead specifically, use a certified filter (NSF 53) and flush your tap before drinking. For health advice about lead exposure, talk to your doctor or call the CDC.
How do I know if my house has a lead service line?
Ask Hamilton Public Water System directly—they are required to know this information or help you find out. Homes built before the 1980s are at higher risk. You can also hire a plumber to inspect your service line or request a utility-conducted assessment.
Will the city replace my lead service line?
Hamilton is required by law to develop a replacement plan, though timelines vary. Contact the utility to ask about their program, cost-sharing options, and whether your home qualifies for priority replacement or rebates.
