Merrimack has six water systems serving about 26,100 people. The largest is Merrimack Village District, which supplies water to roughly 25,500 residents.

What we know about lead service lines here

None of the water systems in Merrimack have reported known lead service lines in their current inventories. However, "no reports yet" does not mean "no lead lines exist"—many utilities are still completing their required surveys.

New Hampshire utilities must identify and map all lead service lines by 2032 as part of federal Lead and Copper Rule updates. Some systems may still be in the process of gathering this information from property records, field inspections, or historical documents.

How to find out about your own service line

Your service line is the pipe that connects your home to the public water main. It may contain lead if your house was built before the late 1980s, when lead pipes and lead-based solder were still common.

Contact your water utility directly to ask:

  • Does my address have a known lead service line?
  • Has my water system completed its service line inventory?
  • Can they test the water at my tap for lead?

Merrimack Village District (the main utility for the area) can answer these questions for most residents in town.

If you're concerned about lead exposure

Lead in drinking water is a real health risk, especially for young children and pregnant people. If you have concerns:

  • Get your water tested. Your utility may offer free or low-cost testing.
  • Use a filter certified for lead (look for NSF/ANSI Standard 53) on any tap you drink or cook from while you wait for answers.
  • Flush your pipes before drinking: let water run for 30 seconds to several minutes if the line has been unused for hours.
  • Talk to your doctor if you're worried about past or current exposure. The CDC has resources on lead and health.

Next steps for residents

  • Contact Merrimack Village District or your local water utility and ask about your service line status
  • Request a free or subsidized water test for lead if your system offers one
  • If your service line is confirmed lead, ask about replacement programs or financial assistance
  • Visit the CDC's lead and water information page for health guidance

Common questions

Does Merrimack NH have lead in the water?

Merrimack's water systems have not reported known lead service lines. However, utilities are still in the process of mapping all service lines. Contact your water utility to ask about your specific address and whether a lead service line test has been done.

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

Call your water utility (Merrimack Village District serves most residents) and provide your address. They can check their records and inventory. Alternatively, a plumber can inspect the line where it enters your home, though this may cost money.

What should I do if my water tests positive for lead?

First, use bottled water for drinking and cooking until you understand your options. Then contact your water utility about service line replacement programs or financial aid. Talk to your doctor if you're concerned about health effects, especially if children or pregnant people live in your home.

Can I remove a lead service line myself?

No—service line replacement requires a licensed plumber and coordination with your water utility. Ask your utility about replacement programs; some offer subsidies or full funding for removing lead lines from low-income households.
