Get your water tested in New Jersey.
The labs New Jersey certifies to test drinking water, from the state’s own list of Oct. 11, 2026. A lab test is the only way to know what is in your own tap or well.
The short answer
New Jersey’s list has 89 labs certified to test drinking water: 39 in New Jersey and 50 in other states. One of the labs here is named for a water utility and may test only its own water, so it comes last.
New Jersey’s list doesn’t say what each lab is certified to test for, or where labs in other states are; those are placed from other states’ lists. These labs it names are left out, because no list places them: Certified Laboratories and Woodard & Curran. Two labs outside the country are left out too.
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
- On a private well: no one else tests it. What to test a well for, and how often.
- On city water: your utility tests what leaves the plant, not what your own pipes add. Testing your tap for lead.
- What it costs: fees vary by lab and by test, and some states test wells for free. What a water test costs.
- Anything your utility’s report flags: a lab certified for that contaminant can test your own tap. New Jersey utilities’ reports.
Source: NJDEP Office of Quality Assurance, certified drinking water labs, dated Oct. 11, 2026, read Oct. 11, 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.
