How we verify labs & regulatory facts
LabVetted is a directory and information service. We do not test water or perform inspections. We compile, organize, and source-check public information so you can find and confirm an accredited provider faster. Here is exactly how.
Sources we use
- EPA (3Ts guidance, Lead & Copper Rule / LCRI, AHERA, PFAS methods, drinking-water lab certification).
- State drinking-water primacy agencies and their lab-certification programs.
- National accreditation bodies: TNI/NELAP (LAMS), A2LA, AIHA-LAP, and (for radon) NRPP.
How a lab gets listed
A lab appears in a state's comparison table only if we can locate it in an official accreditation source for lead in drinking water, and each row links to a verify link so you can confirm it yourself. Where a lab publishes turnaround or pricing, we show it; where it doesn't, we say “request a quote” rather than guess.
Freshness, and its limits
Each compliance page shows when it was compiled and reviewed. That is a point-in-time review, not a live guarantee. Accreditation status, methods, and prices change, so we ask you to confirm a lab's current status directly via its verify link before submitting samples. We re-review listings periodically and on report; we deliberately do not claim continuous real-time verification we can't back up.
Independence, and how listings are ordered
We do not rank by commission. Listings are ordered by type and accreditation: official locators and accredited labs first, then editorial picks, then alphabetically. Many of the accredited labs we list have no affiliate program at all. Some pages include a clearly labeled Sponsored listing, which is a paid placement, but sponsorship never changes which labs appear in the accreditation table, how they are described, or their verification. Verification and advertising are kept separate.
Go straight to the source if you prefer
The official accreditation registries (EPA, NELAP, A2LA, AIHA, and state programs) are the authority, and you can use them directly. LabVetted aggregates those records, organizes them by state and contaminant, re-checks them, and links the official record on every listing, so you can confirm anything yourself. We aim to be a faster, organized front door to the official sources, not a replacement for them.
Not professional advice
This site provides general information and introductions, not medical, legal, or compliance advice. Always confirm requirements with your state agency and a provider's accreditation with the certifying body before acting.
