How many labs test for nitrate in Kansas
24 labs on Kansas's official drinking-water lab list are certified to test for nitrate. All 24 are named for nitrate on the list. 2 of them are marked as taking samples from the public. They are listed first. 17 are located outside Kansas.
The list is published by the Kansas Department of Health and Environment (KDHE) - Environmental Laboratory Improvement Program (ELIPO). List version on file: Live database, searched 2026-11-15 ("believed to be accurate at the time of the search"). Fetched 2026-11-15 (UTC).
Use of this list. KDHE publishes this list with a notice under K.S.A. 45-230, a Kansas law that bars using names or addresses from public records to sell to the people or businesses listed. We show it only to help homeowners find a certified lab; we do not use it to market to the labs.

How the Kansas list marks public samples (whole list). Yes for the 2 listed labs that are on KDHE's Private Well Resource Map of "certified laboratories that conduct private water well testing" (map data last edited August 2023), so call before you send a sample. Not stated for the other labs. KDHE's database also marks each lab 'Commercial?' Yes/No: that is a lab-type flag, not a statement about homeowners' samples.
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 nitrate in Kansas
Nitrate has no taste or smell, and a lab report can state the same water in two units that differ by a factor of 4.43. Read our nitrate explainer.
EPA advises private-well owners to test every year for total coliform bacteria, nitrates, total dissolved solids and pH. [1]
Kansas guidance that mentions nitrate:
- The Kansas Department of Health and Environment (KDHE) and K-State Research and Extension recommend annual water tests for coliform bacteria and nitrate. Testing for common impurities and nuisance contaminants is recommended every one to three years, with possible extra testing after chemical spills or flooding. [2]
- K-State's well maintenance guide recommends testing private wells annually at a minimum; annual maintenance should include testing for coliform bacteria, nitrate, pH and total dissolved solids. [3]
About 149,282 people in Kansas used private wells in 2015, by the USGS estimate of people on domestic self-supplied water. [4] 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: Kansas.
