Get your water tested in New Hampshire.

The labs New Hampshire certifies to test drinking water, from the state’s own list. A lab test is the only way to know what is in your own tap or well.

The short answer

New Hampshire’s list has 63 labs certified to test drinking water: 15 in New Hampshire and 48 in other states. It also names one water utility’s in-house lab, left out here because it tests only its own system’s water. 5 of the labs here are named for a water utility and may test only its own water, so they come last.

New Hampshire’s labs here are those its Environmental Laboratory Accreditation Program accredits for drinking water, as listed in TNI LAMS, the national registry it reports to.

Certification is test by test, so check that a lab is certified for what you want tested, and call first: it will say which bottles to use and how soon the sample has to arrive.

What to ask a lab to test

Source: New Hampshire ELAP, drinking water labs, as listed in TNI LAMS, read Oct. 13, 2026. Labs are listed as the state lists them; what each is certified for is as far as the list says. Certifications change, so a lab’s own word is the latest.

A lab named for a water utility is listed apart. Distances on town pages are straight lines between ZIP code centers from the Census 2020 gazetteer. How labs are listed here.
