Lead Service Lines in Salem, NH

About 22,330 people in Salem get water from 13 different water systems. The largest is Salem Water Dept, which serves roughly 21,000 residents.

What we know about lead in Salem's water

Lead service lines—the pipes that connect the water main to your home—are a concern in older communities across New England. Salem Water Dept and the other local systems have not yet publicly reported the number of known lead service lines or galvanized lines (which can also leach lead) in their inventories.

This doesn't mean there's no lead. Many water systems, especially in towns built before the 1980s, haven't finished surveying their entire service line inventory. Lead service line replacement is expensive and takes time.

Why this matters

Lead can leach into drinking water, especially in homes with older plumbing or acidic water. Children and pregnant people are at highest risk from long-term exposure. Even small amounts matter—there is no safe level.

If you live in an older home, your service line may be lead, galvanized steel, or copper. You won't know without asking your utility or getting your water tested.

What Salem residents can do

Contact Salem Water Dept directly to ask:

  • Does my address have a lead service line?
  • Do you have a map or list I can check?
  • What's your timeline for completing the inventory?
  • Are there programs to help with replacement costs?

You can also request a free or low-cost water test through your utility. A simple test will tell you if lead is present in your home's water right now—regardless of your pipe material.

For health questions, contact your pediatrician or the CDC's lead information line.

Next steps for residents

  • Contact your water utility (Salem Water Dept or the system serving your address) and ask about your service line.
  • Get your water tested if you're concerned, especially if you have young children at home.
  • Check for corrosion control — ask if your utility treats water to prevent lead leaching.
  • Use cold water for drinking and cooking and run the tap for 30 seconds if it hasn't been used in several hours (a precaution, not a guarantee).

Common questions

Does Salem NH have lead in the water?

Lead in drinking water usually comes from pipes and plumbing inside homes and the connection from the street main to the house, not the water treatment plant. Salem Water Dept has not yet publicly reported how many lead service lines exist in its service area. Contact the utility directly to ask about your specific address.

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

Ask your water utility (Salem Water Dept) or check their online map if available. If you can see the water line where it enters your home, a magnet will not stick to lead. You can also get your water tested to see if lead is present.

Is Salem water safe to drink?

Salem Water Dept treats and monitors water quality. However, lead can enter your water through older pipes inside your home. If you're concerned, request a free or low-cost test from your utility and ask about corrosion control treatment.

How much does it cost to replace a lead service line in NH?

Replacement typically costs $1,500–$5,000+ depending on depth and line length. Some utilities offer rebates or low-interest loans. Contact Salem Water Dept to ask about assistance programs in your area.
