Certified well water labs in New York (2026)
More than a million New York homes drink from a private well. The state does not run your annual sample for you. ELAP accreditation, county desks, Cornell Extension drop-offs, a six-county PFAS pilot, and independent mail-in kits do. Here is that system, the fees we could verify tonight, and how to get a PDF without a softener pitch.
The short version
- Call your local health department, then use an ELAP lab. NYS DOH wants coliform every year and a broader panel every three to five years. The sample has to go to an Environmental Laboratory Approval Program (ELAP) lab certified for potable water — not a hardware strip and not a free in-home “test” that ends in a sales visit.
- On Long Island, Suffolk County will collect and analyze for a published fee. Existing approved wells are $100. New or unapproved wells are $350. You do not drop the bottle yourself. Budget weeks, not days.
- If you are in Dutchess, Orange, Putnam, Suffolk, Ulster, or Westchester, check the state’s free PFAS pilot before you buy a PFAS kit. Applications open and pause by county as rebate funds allow.
How New York’s system actually works
Private wells are the homeowner’s job. The state’s private wells page (revised March 2026) and Individual Water Supply Wells Fact Sheet #7 put the floor at coliform bacteria at least once a year, plus other contaminants every three to five years. Fact Sheet #7 also says plainly: do not rely on in-home tests from water-treatment vendors or kits from a store. Those do not meet ELAP standards.
ELAP lives at the Wadsworth Center. Labs that analyze drinking-water samples originating in New York for the regulated methods must be accredited under Public Health Law §502. The public search is Search NY Accredited Environmental Laboratories (linked from wadsworth.org/regulatory/elap). Filter for drinking / potable water and the analyte you need. A lab can be certified for metals and not for coliform. Accreditation does not mean they take a homeowner bottle off the driveway. Call. Ask about residential / private-well samples, bottles, bacteria hold time, Friday rules, price, and whether they email a PDF.
EPA’s national page still points at a PDF of state certification programs. For New York, use ELAP’s search above. Local health department contacts are listed from the DOH private-wells page if you need a county desk first.
County and Extension options we verified
Fees and windows live at the county desk. What we could verify with a public program page tonight:
The table scrolls sideways on a phone.
| Option | What they offer | Listed cost | Catch |
|---|---|---|---|
| Suffolk County DHS Private Well Testing | County staff collect the sample. Typical panel: microbiology, inorganics, VOCs, petroleum products; carbamate pesticides in agricultural areas. Cover letter with recommendations. | $100 existing approved well / valid Certificate of Occupancy. $350 new construction, unapproved well, or no valid C.O. Aldicarb-only in Temik agricultural areas: no fee. Households under $25,000 income can request a notarized fee exemption on the $100 path. | You cannot drop off your own bottle. Sample usually within about six weeks of the check; results often about eight weeks after collection. For a house sale on a deadline, the county itself tells you to use a commercial lab. Bureau of Drinking Water: 631-852-5810. |
| CCE Ontario County → Lozier Environmental | Sterile bottles and instructions at the Canandaigua Ag Office. Bacteria sample to Lozier Environmental Consulting. Results emailed to you and to Extension. | $51 check payable to Lozier Environmental Consulting, Inc. | Collect the morning of drop-off. Keep chilled, not frozen. Deliver Wednesday before 9:00 a.m. at 480 North Main Street, Canandaigua. Call 585-394-3977 x427. Page last updated December 22, 2025 — confirm the fee before you write the check. |
| NYS Private Well PFAS Pilot | Free PFAS testing (EPA Method 537.1 version 2) for private wells in six counties. Rebate path for treatment or public-water connection when PFOA or PFOS hits the state standard. | Free testing while applications are open. Rebates (property owners): up to $5,000 whole-house POET, up to $1,000 point-of-use when POET is not feasible, up to $10,000 to connect to public water. | Counties: Dutchess, Orange, Putnam, Suffolk, Ulster, Westchester. Application windows pause when rebate funds need protecting. Rebate threshold is PFOA or PFOS at or above 10 ng/L (ppt). Post-treatment confirmation must use an ELAP lab and Method 533 or 537.1 v2. Agricultural-only wells are out. |
| Erie County Public Health Laboratory | ELAP-permitted potable-water lab in Buffalo. County environmental health points residents here for private-well chemistry and bacteria; property transfers include a bacteria sample through the health department process. | Call. The lab publishes an Environmental Lab Fee Schedule PDF; we did not invent a dollar figure from a search snippet. | 503 Kensington Avenue, Buffalo. 716-898-6100 · ecphl@erie.gov. Ask about residential bottles, hold times, and Friday rules before you collect. |
We looked for clear public homeowner fee sheets in Nassau, Westchester, Dutchess, Orange, and Onondaga tonight. Several counties point you at ELAP labs or the PFAS pilot without a single walk-up kit price we could quote honestly, so they are not in the table. Call your local health department anyway. If your county runs a program we missed, use it.
What New York guidance actually warrants
Stick to DOH’s cadence unless land use says otherwise. Fact Sheet #3’s recommended residential panel for a new well is the practical catch-up list for an existing well you have never fully checked:
- Every year: total coliform (and E. coli when indicated). Also after well work, a flood, or a change in taste, smell, color, or stomach illness in the house.
- Every three to five years (or for a new well): arsenic, chloride, lead, nitrate, nitrite, iron, manganese, turbidity, sulfate, pH, hardness, alkalinity, sodium — and whatever your local health department adds.
- Regional naturals: barium, fluoride, methane, radium, radon, uranium where those show up in local groundwater.
- Near intensive agriculture: nitrate, pesticides, arsenic, bacteria. Suffolk’s free aldicarb-only option exists for a reason in old Temik potato country — it is not a full well panel.
- Near gas drilling, landfills, dry cleaners, or fuel tanks: chloride, barium, strontium, VOCs — match the hazard, do not buy a random 100-analyte kit and hope.
- After a flood or well work: bacteria first, on the hold-time clock. See our after-a-flood guide.
- For PFAS in the six pilot counties: apply to the state program before you spend $300–$600 on a retail PFAS kit. Details and Method 533 / 537.1 context: PFAS Method 533 / 537.1.
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 (the Friday trap)
Bacteria is on a short clock. CCE Ontario’s Lozier path wants the sample taken the morning of Wednesday drop-off, kept cold, and in by 9:00 a.m. Most commercial labs will not accept Friday bacteria samples or bottles that sat warm all weekend. Suffolk County sidesteps your hold-time problem by collecting the sample themselves — and replaces it with a calendar problem (weeks to collection and weeks to results).
Plan the collection day around the receiving hours, not around your Saturday free time. A voided sample is the clock, not a conspiracy. More: what to test after a flood.
Mail-in kits that work from New York
Independent mail-in labs ship to and from New York as ordinary domestic US kits. They email a PDF. They are not selling you a softener in the same breath. For a New York compliance or lender ask, confirm the lab is (or partners with) an ELAP-accredited potable-water lab for the methods you need — accreditation is what DOH and many underwriters care about. Listed prices we checked on September 9, 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. For bacteria alone in Finger Lakes country, the $51 Lozier drop through CCE Ontario is often cheaper than a national kit. PFAS is usually a separate kit — or free through the pilot if you qualify.
Side by side for a New York well
The table scrolls sideways on a phone.
| County / Extension | ELAP commercial drop-off | Mail-in (Tap Score / NTL) | |
|---|---|---|---|
| Best for | Published county fees (Suffolk), cheap bacteria drop (CCE Ontario), free PFAS in the six pilot counties | Fast local turnaround, lender-named labs, methods already on ELAP scope | Broader panel and a PDF without waiting six weeks for a county sampler |
| PDF? | Suffolk mails a letter and results. CCE Ontario’s lab emails. Ask before you pay. | Yes — ask for the emailed report | Yes. Email is the product |
| Sales visit? | No | No | No |
| Lender / CoC? | Sometimes fine for a simple bacteria condition. Suffolk itself says use a commercial lab for a closing deadline. | Often what the underwriter named. Confirm before you sample. | Sometimes not. Ask before you sample. See home purchase / lender CoC. |
Real estate and lenders
New York does not impose one statewide private-well sampling mandate at every sale the way a few states do. Local health departments and underwriters still do. Erie County’s property-transfer process includes a bacteria sample on the well. Suffolk’s county program will not promise closing-speed turnaround. Confirm the lab, the analyte list, ELAP status, and the form with the underwriter before you fill a bottle. A mail-in kit can be a perfectly good health file and still bounce at the bank. 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 New York
- Call your local health department and ask how private-well samples work in your county. On Long Island, start with Suffolk’s private-well program if you are in Suffolk.
- Open ELAP’s search at Search NY Accredited Environmental Laboratories, pick drinking / potable water and your analyte, then call the lab about residential samples.
- If you are in the six PFAS pilot counties, apply at health.ny.gov/environmental/water/drinking/privatewellspilot/ before you buy a retail PFAS kit.
- If you just want a PDF this month, use Tap Score / SimpleLab or National Testing Laboratories (Watercheck). Confirm ELAP coverage if a regulator or lender is involved. Do not collect the bacteria bottle on Friday.
- Match the panel to the land. Bacteria every year. Broader chemistry every three to five years. After a flood, start with bacteria.
Not this if…
- A lender named a local lab and a chain-of-custody form. Use that lab. Do not substitute a mail-in kit and hope.
- Someone offered a free in-home “test” that ends in a softener pitch. That is not on this page. Fact Sheet #7 already told you those tests do not meet ELAP. 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 expected a full statewide lab phone book with hours. We refused to invent one. ELAP’s search plus a phone call is the honest path until we verify individual labs take homeowners.
