How the South Dakota list marks public samples (whole list). Yes for the South Dakota State Health Laboratory: the SD Department of Health's "Testing Private Wells" page says "To request sample bottles for testing of water supplies, please complete and submit the following form, indicating the number of bottles needed for each test specified. Bottles include complete instructions for collecting and submitting water samples for testing. Fee information for the various tests is included. Sample bottles and instructions are also available from County Extension offices." (tests on the form: Bacteria/Nitrate, Lead, New Well, Other). Not stated for the other labs; DANR's list is written for public water systems ("Certified laboratories use approved methods to analyze drinking water compliance samples from public water systems (PWSs)."). DANR's Private Well Sampling page names no lab.
Before you send a sample, call the lab to confirm it is currently certified for the exact test and method, that it accepts samples from homeowners, and how to collect and ship them. Status can change between list updates.
Why test for PFAS in South Dakota
EPA's 4.0 ng/L limits for PFOA and PFOS cover public water, not private wells, and its May 2026 proposals to roll back four other PFAS limits are not final. Read our PFAS explainer.
About 128,711 people in South Dakota used private wells in 2015, by the USGS estimate of people on domestic self-supplied water. [1] Federal limits are written for public water systems, not private wells, so testing is up to the owner.
For tests that depend on your home (farms nearby, old plumbing, a new baby), use the which-tests checklist. When results arrive, check your numbers against EPA's limits. State guidance, county data and every lab: South Dakota.
