MASON CITY WATER DEPARTMENT Lead Service Line Inventory
Mason City Water Department serves approximately 27,338 people in Iowa. Like water systems across the US, the utility is required to maintain an inventory of lead service lines (LSLs)—the pipes that connect homes to the water main.
What we know about lead service lines in Mason City
The water department draws from groundwater sources. However, we don't currently have data on how many lead service lines are in the system. The utility has not yet published a detailed inventory showing the count of lead, non-lead, galvanized, or unknown service lines.
This doesn't mean there's no lead in Mason City's system. It means the inventory information isn't publicly available yet—either because testing and documentation are still underway, or the data hasn't been shared in an accessible format.
Why service line material matters
Lead service lines can leach lead into drinking water, especially in homes with acidic water or older plumbing fixtures. If your home was built before the 1980s, there's a higher chance your service line contains lead. Even homes built after that era may have lead components in their internal plumbing.
The best way to know your home's status is to contact your water utility directly or have your water tested.
What Mason City residents can do now
Contact the water department to ask about your specific property's service line material. Many utilities can look up this information by address, even if a full public inventory isn't published yet.
If you're concerned about lead in your home's water, you can request a water test. Some utilities offer free or subsidized testing; others can recommend certified labs. The EPA recommends testing if your home has a lead service line or was built before 1986.

Frequently asked
How do I know if my Mason City home has a lead service line?
Contact Mason City Water Department with your address—they may be able to tell you based on property records or the utility's inventory. If they don't have that information readily available, you can also hire a plumber to inspect the line where it enters your home, or request a water lead test.
Is the water in Mason City safe to drink?
Mason City Water Department is required to test for lead and report results to the EPA. You can request a copy of their most recent water quality report (called a CCR) to see their lead findings. If you're concerned, a home water test can measure lead in your specific water.
What should I do if I find out my service line is lead?
You have options: install a point-of-use water filter certified for lead, use bottled water for drinking and cooking, or plan a service line replacement (which the utility may help fund in some cases). Talk to Mason City Water Department about available programs and financial assistance.
When will Mason City publish a complete lead service line inventory?
Federal law requires utilities to inventory lead service lines on their property, but deadlines and transparency timelines vary. Contact the water department or check their website for updates on when a full public inventory will be available.
