How the Texas list marks public samples (whole list). Not stated in the list. TCEQ marks each lab 'Commercial?' Yes/No; that is 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 uranium in Texas
Uranium comes from rock, mainly harms the kidneys, and often shows up first as a gross alpha radioactivity number. Read our uranium explainer.
About 1,315,073 people in Texas 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: Texas.
