How the Nevada list marks public samples (whole list). Yes for the 13 labs on NDEP's table of "in-state Nevada Certified Drinking Water Laboratories that accept samples from the public" ("last updated May 15, 2025"; the table image is dated 9-7-2023), so confirm by phone. Not stated for the other labs. NDEP's database also marks each lab 'Commercial?' Yes/No: that is a lab-type flag, broader than 'homeowner', so call before you send a sample.
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 manganese in Nevada
Black stains start around EPA's 0.05 mg/L guideline, but the health numbers sit higher and vary by agency, especially for babies on formula. Read our manganese explainer.
About 192,557 people in Nevada 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: Nevada.
