PFAS testing
For independent drinking-water testing, contact a state-certified drinking-water laboratory and ask whether its current certification scope covers PFAS. For a private well, you may ask your state program for guidance or contact a certified laboratory about testing.
Water Testing Finder lists 2,010 laboratory records across 22 certifying states. These are database counts, not a claim that every currently certified laboratory nationwide is listed.
Labs for home testing: 1,599. Commercial and industrial: 295. Plant and utility: 116.
Water Testing Finder lists laboratories from official state certification records. A listing does not establish that a laboratory currently tests for PFAS or accepts residential samples. Confirm its current test scope, sample acceptance, collection instructions, and fees with the laboratory.
Frequently asked questions
How do I find a certified laboratory for PFAS testing?
Choose a state and review the laboratory’s certification record. Ask the laboratory whether its current scope includes the PFAS test you need and request its sample instructions.
Can the US Environmental Protection Agency test my household water on request?
No. The US Environmental Protection Agency says it is unable to test residential or commercial drinking water upon request. It encourages individuals seeking independent testing to contact a state-certified drinking-water laboratory.
Does a listing mean a laboratory accepts private-well samples?
No. Certification alone does not establish residential sample acceptance. Confirm directly with the laboratory.
