Get your water tested in South Dakota.

The labs South Dakota 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

South Dakota’s list has 16 labs certified to test drinking water: 4 in South Dakota and 12 in other states.

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

  • South Dakota Public Health Laboratory

    Sample bottles for testing a private well for bacteria and nitrate, lead, or a new-well panel, ordered online from the lab or picked up at a County Extension office. Instructions and fees come with the bottles.

What to ask a lab to test

Source: South Dakota DANR, laboratories certified for the analysis of drinking water, read Oct. 10, 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.
