Lead Service Lines in Mandan, ND

About Lead Service Lines

A lead service line is the pipe that carries water from the main water line under the street into your home. If your home was built before 1986, there's a chance your service line contains lead—a toxic metal that can leach into drinking water, especially in acidic water or after long periods of sitting in pipes.

The good news: lead service lines are fixable. Many communities are replacing them, and there are steps you can take right now to reduce exposure.

What We Know About Mandan

Mandan is served by five water systems that together provide water to 26,754 residents. The largest is the City of Mandan, which serves 21,769 people.

Current data: None of the water systems in Mandan have reported known lead service lines in their public inventories. However, this does not mean lead service lines don't exist. Utilities are still in the process of mapping and testing their infrastructure, especially in older neighborhoods. Unknown service line materials are common nationwide.

What You Should Do

If you live in Mandan:

1. Find out what your service line is made of. Contact your local water utility—they may have records or can send someone to inspect the connection at your home's foundation. The inspection is usually free.

2. Don't wait for a government replacement program (though Mandan may eventually start one). If you own your home and your service line is lead, you can replace it at your own expense—typically $3,000–$12,000 depending on property size and soil conditions. Some utilities offer rebates or low-interest loans.

3. Reduce exposure in the meantime. Use a certified lead filter (NSF/ANSI Standard 53), flush your pipes by running cold water for 30 seconds before drinking or cooking, and avoid boiling water as a "fix" (boiling concentrates lead).

4. Have your water tested if you're concerned. Your utility can recommend a certified lab.

Next Steps for Residents

  • Contact your water utility (see list below) and ask if your service line has been tested and what material it is.
  • Request a free or low-cost water test through your utility or local health department.
  • If lead is confirmed, ask about replacement assistance programs or financing options.
  • For health questions about lead exposure, especially if you have young children, speak with your pediatrician or call the CDC's lead hotline: 1-800-CDC-INFO.

Common questions

Does Mandan have lead in the water?

Lead is not in the treated water itself—the risk comes from lead service lines (pipes) that connect homes to the main water line. No lead service lines have been reported in Mandan's current utility records, but testing is ongoing and older homes are more likely to have them.

How do I know if my house has a lead service line?

Contact your water utility and ask. You can also look at your home's foundation where the water line enters—lead pipes are soft and dull gray. A utility inspector can confirm it. Homes built before 1986 are at higher risk.

Is lead service line replacement expensive?

Yes, typically $3,000–$12,000, but you may qualify for rebates, grants, or low-interest loans from your utility or local government. Ask your water provider what programs exist.

What should I do right now if I'm worried about lead?

Use an NSF-certified lead filter on your tap, flush cold water for 30 seconds before drinking, and have your water tested through your utility. Contact your doctor if you have health concerns.
