Get your water tested in Pennsylvania.

The labs Pennsylvania 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

Pennsylvania’s list has 108 labs certified to test drinking water: 53 in Pennsylvania and 55 in other states. It also names 57 water utilities’ in-house labs, left out here because they test only their own systems’ water.

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.

From the state

  • Penn State Agricultural Analytical Services Laboratory

    Drinking water test kits from many county Extension offices, mailed back to the lab overnight with payment. Packages cover bacteria and basic chemistry, with add-ons for nitrate, metals, lead, and mining or gas drilling concerns. The standard package of bacteria, pH and total dissolved solids is $60, or $70 with nitrate; bacteria alone is $40, nitrate $15 and lead $25.

What to ask a lab to test

Source: Pennsylvania DEP Laboratory Accreditation Program, accredited labs for drinking water, 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.
