Find a Water Test: The Full Resource Directory
The fastest way to get your water tested is often a free phone call, not a purchase. This directory covers the national hotlines, every state’s certified-lab program, and at the bottom, the commercial mail-in services worth paying for when you need a broader panel or your local options are thin. Start at the top and work down.
These cost nothing. Most people on private wells should start with the first two calls before ordering anything online.
Private Well Owner Hotline
Run by the National Ground Water Association (NGWA). They’ll point you to certified labs and local resources in your area, and answer the “where do I even start” question at no charge.
855-420-9355
Mon–Fri 8:30 am – 4:30 pm ET
EPA Safe Drinking Water Hotline
Federal questions: is this contaminant regulated, what’s the legal limit, where do I read the rule, what do I do about it. They also help you find state certified labs.
800-426-4791
Mon–Fri 10 am – 4 pm ET
EPA Certified Lab Finder
The official state-by-state index of every drinking-water lab certified in your state. Pick your state from the map or list; it links you directly to your state program’s certified-lab directory.
Your Consumer Confidence Report
If a utility sends you a bill, your CCR — the annual water quality report utilities are legally required to publish — is already free and waiting. Most utilities post it online. Search “[your city] Consumer Confidence Report” or call your utility and ask for it by name.
Each state shows two tiers: Free / Gov (certified-lab program + state health dept) and Free / Low-Cost (Extension programs, state labs that accept public samples, special programs). Where a state has a notable in-state commercial lab, that appears too. All gov links verified June 2026.
ADPH — Well Water Testing
County health depts offer bacteria testing for private wells — call yours first. Not all counties participate and fees vary ($15–$30 typical).
Alaska DEC does not test private wells. No statewide Extension water testing program. Contact the public health center nearest you or use a DEC-certified lab directly.
Drinking Water Safety
ADH tests private well samples for bacteria and E. coli only — pick up a kit from your local health unit. For nitrates, metals, VOCs, or anything beyond microbial, you need a private certified lab.
DC is served entirely by DC Water; no private well program. Lab certification handled by EPA Region 3.
Note: Purdue Extension’s dedicated water quality program no longer exists.
Note: ISU Extension coordinates the testing process and points to certified labs — they do not perform the testing themselves.
Note: this is a paid state testing service — there’s a fee, it’s not free.
Note: UMass does not provide water testing for private citizens — use their certified lab search or a commercial service for residential testing.
Note: MSU does not provide water testing services — they provide information and direct you to certified labs.
UMN Extension — Test Well After Flooding
UMN’s water testing is conducted through NRRI (first link).
Gov links verified June 2026 from primary sources. If a link returns 404, go to the state agency’s main site and search “drinking water laboratory certification.” The EPA certified-lab finder is the single most stable fallback for any state. Extension program links are the most likely to move — if one is broken, search “[state] cooperative extension well water testing.”
Free options didn’t fit your situation? These services are worth paying for when your local health department doesn’t run the panel you need, your area is thin on certified labs, or you want a broader result set with professional interpretation. They’re listed here rather than at the top because that’s where they belong — not because there’s anything wrong with them.

Affiliate disclosure: Tap Score (SimpleLab) is an affiliate partner — if you buy through our Tap Score links, we may earn a small commission at no extra cost to you. NTL WaterCheck and ETR Laboratories are listed without any affiliate relationship; we have no financial arrangement with them. That distinction is exactly why the free government resources are at the top of this page and commercial services are at the bottom. Affiliate revenue doesn’t change which option we think you should start with — for most people, it’s the free one. The testing overview at cleanwaterladies.com/testing/ explains more.
Government resource links verified June 2026. State agency websites reorganize occasionally — if a link 404s, go to the state agency’s main site and search “drinking water laboratory certification” or “private well testing.” The EPA certified-lab finder at epa.gov/dwlabcert is the single most stable reference and is maintained by EPA directly.
