Certified well water labs in Nevada (2026)
Nevada does not regulate private wells the way it regulates public systems. The state counts about 51,000 domestic wells (NDWR 2021 pumpage inventory), and USGS/NGWA put roughly 193,000 people on self-supplied domestic groundwater (2015). NDEP’s private-well page points you to certified labs. A Healthy Nevada Project study of 174 private-well households found 22% above the EPA arsenic MCL of 10 µg/L, and 8% above guidelines for uranium and iron (PMC9588670).
The short version
- Use a Nevada SDWA-certified lab for lender / real-estate testing. NRS 445A.863 says testing required by a lender as a condition of a real-property transfer must be done by a lab certified by Nevada under the Safe Drinking Water Act. Ask: “Are you certified by the State of Nevada to analyze Drinking Water compliance samples?”
- WETLAB posts a flat Domestic Well Suite. WETLAB charges $624 all-inclusive for anions, heavy metals (including arsenic), and bacteria. Pickup bottles/cooler at Sparks, Elko, or Las Vegas; drop samples Mon–Thu; email results in 10 business days. They do not sell water treatment.
- Or start from NDEP’s public-accepting certified list. The Get Your Drinking Water Tested page (list updated May 15, 2025) lists Nevada-certified labs that accept samples from the public. Costs vary — call for a private-well quote.
How Nevada’s system actually works
NDEP’s Bureau of Safe Drinking Water regulates public systems, not private wells. Homeowners are responsible for their own testing. Extension’s Understanding Lab Results PDF recommends a Routine Domestic Analysis about every three years as a chemistry baseline, plus bacteria when you need it. For a sale or refinance, the lender rule is statutory: only a Nevada SDWA-certified lab counts under NRS 445A.863. A lab certified only under CWA or RCRA is not enough for that purpose. There is no statewide free private-well testing program comparable to some neighboring states — do not expect a free state bottle unless a local Extension or county event says so.
Options we verified
- WETLAB Western Environmental Testing Laboratory — Domestic Well Suite $624. Flat fee inclusive of all analytical charges: anions, heavy metals (arsenic by 200.8 among them), and bacteria (total coliform). Pick up cleaned bottles, cooler, and instructions at Sparks, Elko, or Las Vegas; complete their Domestic Well Chain of Custody; drop samples Monday–Thursday only (Sparks 8 a.m.–6 p.m., Elko 9 a.m.–4 p.m., Las Vegas 8 a.m.–4 p.m.). Results emailed in 10 business days — no expedite. Pay by check or Visa/Mastercard when you submit. Phones: Sparks (775) 355-0202 · Elko (775) 777-9933 · Las Vegas (702) 475-8899. Nevada drinking-water cert Sparks NV00925 (expires 7/31/2026). Source: wetlaboratory.com/domestic-well-testing (checked Oct 13 2026). Independent lab — not a treatment seller.
- Silver State Analytical Laboratories (SGS Silver State) — Nevada-certified scopes in Las Vegas / Reno / Elko and commonly listed among labs that accept public samples. No current public homeowner price list verified tonight (older county fee tables are too old to quote). Call for a private/domestic quote and confirm SDWA drinking-water certification for the analytes you need. Directory phones often listed: Las Vegas (702) 873-4478 · Reno (775) 825-1127. Confirm hours and drop-off on the phone. Also see the NDEP public-accepting list.
- Other labs on the NDEP public-accepting certified list (updated May 15, 2025). NDEP says costs vary and to contact labs for pricing. Use the table on Get Your Drinking Water Tested and ask the SDWA compliance question above before you drive.
What to test for in Nevada
- Bacteria (total coliform / E. coli): at least yearly, and after any well work, flood, or unexplained illness.
- Routine Domestic Analysis chemistry: about every three years per Extension’s Understanding Lab Results guidance — anions, metals, and related indicators your lab packages together.
- Arsenic: a known natural issue in parts of Nevada. The Healthy Nevada Project private-well study found 22% of sampled households above 10 µg/L.
- Uranium and iron: the same study found 8% above relevant guidelines; ask your lab if those are in the suite or need an add-on.
- Lahontan Valley / Fallon: deeper wells (over about 50 ft) should consider radioactivity / gross alpha. University of Nevada Extension Fallon: 775-423-5121.
- Near agriculture, septic systems, or after floods: nitrate every year, plus whatever your county or Extension flags locally.
Mail-in kits (for a broader PDF)
These are independent labs that mail you bottles, run the tests, and email a PDF. Neither one sells softeners. Listed prices checked for this ship:
- Tap Score / SimpleLab Essential Well: $209 listed (includes arsenic and uranium among 54 analytes).
- National Testing Laboratories WaterCheck Basic: $220 listed; next-day return shipping not included.
If a lender, buyer, or title company needs a Nevada SDWA-certified result under NRS 445A.863, a self-collected mail-in kit may not count. Use a lab on the NDEP certified drinking-water list and ask about chain of custody.
Side by side for a Nevada well

| WETLAB Domestic Well Suite | Other NDEP certified labs | Mail-in (Tap Score / NTL) | |
|---|---|---|---|
| Best for | Posted flat fee covering anions, metals (incl. arsenic), and bacteria | Local drop-off when WETLAB is far; lender SDWA work | A broader analyte list in one PDF |
| Typical cost | $624 flat (analytical) | Call for fees | About $209–$220 |
| Drop-off | Sparks, Elko, or Las Vegas (samples Mon–Thu) | Per lab on the NDEP list | Ship it yourself |
| Real estate? | Ask the lender; NV SDWA-certified | Ask the SDWA compliance question | Usually no under NRS 445A.863 |
Remind me to test my well every year
CDC and EPA say to test a private well at least once a year. We’ll send one email a year, about when your test is due, with your state’s lab options.
Thanks, you’re on the list. We’ll email you once a year when it’s time to test your well. Nothing else.
What to do in Nevada
- If a lender needs a result, use a Nevada SDWA-certified lab and ask the compliance-sample question. Cite NRS 445A.863.
- For a posted statewide suite, WETLAB’s $624 Domestic Well Suite covers anions, heavy metals including arsenic, and bacteria — Sparks, Elko, or Las Vegas.
- Otherwise call a lab on NDEP’s public-accepting certified list (updated May 15, 2025) for a private-well quote.
- Plan chemistry about every three years (Extension Routine Domestic Analysis) and bacteria at least yearly — plus arsenic/uranium where geology warrants it.
- Got a positive result? Disinfect, flush, and retest before you buy any treatment. You don’t have to buy from anyone who tested your water.
- If you want a broader PDF, use Tap Score / SimpleLab or National Testing Laboratories.
Not this if…
- You already chlorinated the well. Wait and flush before a bacteria sample, or the result means nothing.
- The “lab” quoting you is also selling a treatment system. Get an independent result. See the Home Depot free-kit comparison.
- Someone offered a free in-home “test” that ends in a softener pitch. That is not on this page.
