Certified well water labs in Arkansas (2026)
USGS’s Arkansas water-use report for 2010 (SIR 2015–5062) estimated about 144,000 people — roughly 5 percent of the state — on private wells, with public supply covering about 94 percent. That is a dated estimate, not a 2026 census. ADH’s Glen F. Baker Public Health Laboratory will test a private drinking-water sample for total coliform and E. coli only for $17. Chemistry, minerals, and PFAS go through a private environmental lab, Extension / AWRC diagnostics (with a drinking-water-cert hedge), or a mail-in kit that emails a PDF.
The short version
- Pick up an ADH Water Collection Kit at your local health unit — do not invent a random bottle. Collect from a drinking-water faucet per the instructions. Enclose a $17 check or money order payable to the Arkansas Department of Health plus the sample form. Hand the kit back to the health unit before the ADH courier runs, or deliver to the Glen F. Baker Public Health Laboratory at 201 S. Monroe St., Little Rock, AR 72205.
- Respect the 30-hour clock and the Thursday cutoff. The lab must receive the sample within 30 hours of collection, 8:00 a.m.–4:00 p.m. Monday through Friday (except legal holidays). Local health units will not accept samples after Thursday’s courier pick-up until the first working day of the next week. USPS is not recommended unless overnight.
- For nitrate, metals, VOCs, or PFAS, leave the ADH bacteria path. ADH does not test private samples for minerals, parasites, or chemicals. Use a private environmental lab (ADH publishes a short resource list with a no-endorsement disclaimer), ask Lab Certification at adh.lab@arkansas.gov for the current certified drinking-water lab list (EPA still says “submit request” for Arkansas), or use a mail-in kit that emails a PDF.
How Arkansas’s system actually works
Private wells are the homeowner’s job. The Safe Drinking Water Act does not cover those taps. ADH’s Water Microbiology Laboratory page is blunt: private drinking-water samples can only be tested for total coliform bacteria and E. coli; minerals, parasites, and chemicals go to a private environmental laboratory. The service is for drinking-water sources — not ponds, creeks, toilets, or bathtubs.
Start at your local health unit for a Water Collection Kit. ADH’s collection instructions (and the companion illustrated PDF) set the fee at $17.00 per sample, payable by check or money order to the Arkansas Department of Health — no payment, no test. Results are a bacteria health check. The same ADH page notes people also use this path for mortgage-related testing; that does not automatically mean the underwriter will accept bacteria-only results when the loan asked for a chemistry panel or a named lab.
ADH’s EPA Drinking Water Certification program currently certifies public water utility laboratories for microbiology only. Lab Certification Officers take written requests at adh.lab@arkansas.gov. EPA’s national contacts PDF still lists Arkansas’s drinking-water lab list as submit request — we found no public statewide commercial certified-lab PDF to scrape tonight. Do not invent a phone book from memory.
On the same private-well page, ADH lists three Environmental Testing Laboratories as a resource — Eurofins Environment Testing-Little Rock, Arkansas Analytical Inc., and Environmental Services Co Inc. — with an explicit disclaimer that ADH does not endorse or recommend any specific lab. That is a resource list, not a claim that those names are the full certified drinking-water directory or that they accept walk-up private-well kits tonight. Call each lab yourself.
University of Arkansas Cooperative Extension’s water diagnostic testing page points homeowners to the Arkansas Water Resources Center Water Quality Lab in Fayetteville for chemistry packages (partial listed prices on the Extension page; confirm current pricing with the lab). AWRC’s own domestic-packages fact sheet says the lab is ADEQ-certified but that certification does not cover drinking water — treat those reports as general guidance unless your underwriter or regulator named that path. AWRC contact listed tonight: 479-502-9843 / awrcwql@uark.edu.
CDC and EPA both frame the annual minimum as total coliform bacteria, nitrates, total dissolved solids, and pH, plus whatever is a local problem. EPA’s national page still points at a PDF of state certification programs.
Options we verified
Fees and rules live on the ADH Water Microbiology page, the private-water collection PDFs, the Extension / AWRC pages, and the mail-in product pages. What we could verify with a public URL tonight:
The table scrolls sideways on a phone.
| Option | What they offer | Listed cost | Catch |
|---|---|---|---|
| ADH Glen F. Baker PHL bacteria path | Kit from local health unit. Self-collect per instructions (flame faucet, fill to 100 mL line — do not rinse bottle). Lab path: total coliform / E. coli only. Return via ADH courier or hand-deliver to 201 S. Monroe St., Little Rock, AR 72205. Lab email: adh.lab@arkansas.gov. ADH: 1-800-462-0599. | $17.00 check or money order payable to Arkansas Department of Health (instructions PDFs). Sample will not be tested without payment. | Bacteria only. No minerals, parasites, or chemicals. Must arrive within 30 hours; lab receives Mon–Fri 8 a.m.–4 p.m. No LHU drop after Thursday courier until next work week. Ask how a written copy arrives if you need a file for a lender. |
| ADH drinking-water lab certification | ADH certifies public water utility labs for microbiology only at present. Written request to Lab Certification Officers at adh.lab@arkansas.gov. EPA’s contacts PDF still says Arkansas’s DW lab list is submit request. | Ask for a quote from whichever lab ADH confirms is currently certified for the methods you need. | No public statewide commercial certified-lab PDF found tonight. Utility micro-cert ≠ homeowner walk-up hours. Prefer a live confirmation from ADH over any third-party scrape. |
| ADH resource list — private environmental labs (examples only) | Names published on the ADH Water Microbiology private-well page: Eurofins Environment Testing-Little Rock, Arkansas Analytical Inc., and Environmental Services Co Inc. ADH explicitly does not endorse them. | Ask each lab. No prices on the ADH page. Contact fields are not published on that ADH list tonight. | Examples from the official resource list — not a claim that any accepts private-well walk-ups tonight, and not the full certified DW directory. Call first. We did not invent phones or hours from memory. |
| UA Extension / AWRC Water Quality Lab | Extension points to AWRC WQL (Fayetteville) for domestic / diagnostic chemistry packages. AWRC: 479-502-9843 / awrcwql@uark.edu. Extension Little Rock: 501-671-2000. | Extension page partial list (confirm current): pH $10, conductivity $10, hardness $30, alkalinity $15, total solids $20, metals suite $50, total phosphorous $20. | AWRC’s domestic fact sheet says ADEQ certification does not cover drinking water. Useful guidance / chemistry context — not automatic lender CoC or ADH micro-path substitute. Contact your county agent. |
| Separate county health fee schedule | We searched for a published county-level homeowner well-test fee page distinct from ADH’s statewide $17 kit path. | None found tonight. | Arkansas’s published homeowner bacteria path is the ADH kit + PHL / courier system via local health units. Do not invent a county price from another state (including Missouri’s Pulaski County Health Center). |
ADH will not analyze nitrate, metals, VOCs, pesticides, or PFAS on the private-well bacteria path. Hardware-store strips are screening-only. AWRC domestic reports are general guidance unless your underwriter named that lab.
What Arkansas guidance actually warrants
Match the panel to the land. ADH, UA Extension / AWRC framing, EPA private-well pages, and CDC testing guidance line up on the core schedule:
- Every year: total coliform bacteria (ADH kit / PHL path when the 30-hour clock works). Nitrate every year, and always before the water goes to an infant under six months — nitrate is chemistry, so use a private environmental lab, AWRC / Extension path (with the DW-cert hedge), or mail-in — not the ADH bacteria bottle alone.
- After a flood, well work, a dry-then-recovered well, or a change in taste / color / odor: bacteria first. See our after-a-flood guide.
- Metals, hardness, iron staining, or lead from plumbing: a private environmental lab, Extension / AWRC metals suite (confirm current price and whether the report meets your need), or mail-in. Not the ADH bacteria path.
- Near tanks, industry, agriculture spray programs, or known spills: ask a commercial lab about VOCs, herbicides, or pesticides.
- PFAS concern: we found no Arkansas private-well PFAS free-testing program tonight. ADH’s drinking-water communications discuss public-system PFAS rulemaking — not a free private-well panel. Use a lab that offers Method 533 / 537.1, or a mail-in PFAS panel. Details: PFAS Method 533 / 537.1.
- Lead: plumbing is the usual source, not the aquifer. Flush cold water; never cook from the hot tap; only a certified analysis measures it.
When the Certificate of Analysis or the ADH written results arrive, more: how to read a well water report.
Hardware-store strips are screening-only. They are not an annual well test and they are not what a lender means by “tested.”
Hold times and collection
Plan around the 30-hour receipt clock and the lab’s Monday–Friday 8:00 a.m.–4:00 p.m. window. Ask your local health unit when the ADH courier picks up. After Thursday’s courier time, the health unit will not take samples until the next work week — do not collect into a dead weekend. Hand-delivery to Glen F. Baker PHL is the alternate. Flame the faucet carefully (plastic melts); fill to the 100 mL line; do not rinse the bottle. More on bacteria clocks after weather events: what to test after a flood.
Mail-in kits that work from Arkansas
Independent mail-in labs ship to and from Arkansas as ordinary domestic US kits. They email a PDF. They are not selling you a softener in the same breath. For a lender or local compliance ask, confirm the analyzing lab meets what the underwriter named. Listed prices we checked on September 22, 2026:
- Tap Score / SimpleLab Essential Well: $209 listed (54 analytes; standard shipping and prepaid return on the product page).
- National Testing Laboratories WaterCheck Basic: $220 listed plus free delivery on watercheck.com. Next-day return shipping is not included. Budget for overnight return on the bacteria bottle.
Those are listed prices, not coupons. Kits change. Read the current product page before you buy. If the ADH $17 bacteria path covers your question — and you can hit the 30-hour clock — check that path before you spend $200 on a national kit for the same core bacteria question. For nitrate and metals, mail-in or a private environmental / Extension path is the honest next step.
Side by side for an Arkansas well
The table scrolls sideways on a phone.
| ADH PHL bacteria | Private environmental / AWRC | Mail-in (Tap Score / NTL) | |
|---|---|---|---|
| Best for | Low-cost annual bacteria when the 30-hour / courier clock works | Nitrate, metals, VOCs, PFAS, lender-named labs, local chemistry | Broader baseline panel and a PDF when local scheduling does not fit |
| PDF? | Written ADH results. Ask how a copy arrives if you need a digital file. | Yes — ask for the emailed Certificate of Analysis (confirm DW-cert / underwriter acceptance for AWRC) | Yes. Email is the product |
| Sales visit? | No | No, if you stay with an independent lab | No |
| Lender / CoC? | Bacteria health check — ADH mentions mortgage use cases, but do not assume it meets underwriter chemistry / CoC language. Ask before you treat it as the closing test. | Often what the underwriter named when the lab’s certification scope matches. Confirm before you sample | Sometimes not. Ask before you sample. See home purchase / lender CoC |
Real estate and lenders
Ask the underwriter what parameters and which lab they will accept, then use a lab whose certification scope matches the loan conditions for anything beyond a personal health file. Confirm the lab, the analyte list, certification scope, and the chain-of-custody form before you fill a bottle. An ADH coliform result can be a perfectly good health check and still bounce at the bank if the loan asked for a chemistry panel or a named lab. More: home purchase / lender chain of custody.
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 Arkansas
- Get a kit from your local health unit, or call ADH at 1-800-462-0599 / email adh.lab@arkansas.gov if you need the lab path clarified.
- Bacteria: collect per instructions, enclose $17, hit the 30-hour clock, avoid the Thursday-after-courier dead zone.
- Nitrate, metals, or a broader panel: call a lab on ADH’s resource list (examples only), request the current certified DW list from adh.lab@arkansas.gov, ask Extension / AWRC with eyes open on the DW-cert hedge, or use mail-in. ADH’s private-well path will not do chemistry.
- PFAS: no AR private-well free PFAS program found tonight. Buy a Method 533 / 537.1 mail-in panel, or ask a commercial lab that offers those methods.
- If you want a broader PDF this month and the courier clock does not fit, use Tap Score / SimpleLab or National Testing Laboratories (Watercheck).
- Match the panel to the land. Bacteria every year. Nitrates every year, especially before a newborn. After a flood, start with disinfection and bacteria.
Not this if…
- A lender named a local lab and a chain-of-custody form. Use that lab. Do not substitute an ADH bacteria result and hope.
- Someone offered a free in-home “test” that ends in a softener pitch. That is not on this page. See the Home Depot free-kit comparison.
- You only wanted a strip from the hardware aisle. Fine as screening-only. It is not a certified analysis.
- You planned to drop a chemistry bottle at ADH for minerals or PFAS. That path does not test minerals, parasites, or chemicals. That is the rule on the page, not rudeness.
- You expected a full statewide commercial phone book with hours and “yes we take homeowners.” We refused to invent one. ADH’s resource list plus a phone call — or a request to adh.lab@arkansas.gov — are the honest path until we verify individual walk-up hours.
- You treated an AWRC domestic report as an ADH-certified drinking-water Certificate of Analysis. Their fact sheet says ADEQ certification does not cover drinking water. Screening / guidance context unless the underwriter said otherwise.
- You assumed every name on the ADH resource list is “ADH-certified for drinking water” and open for walk-ups. ADH disclaims endorsement. Call first.
- You collected Friday for a Saturday fantasy drop. Lab receiving is Mon–Fri; LHUs cut off after Thursday courier. The 30-hour clock does not care about your weekend.
