How many labs test for VOCs in Arizona
14 labs on Arizona's official drinking-water lab list are certified to test for VOCs. Of these, 14 hold a group certification that includes it. The Arizona list does not say which labs take samples from homeowners, so call a lab before you send one. 10 are located outside Arizona.

How the Arizona list marks public samples (whole list). Not stated per lab. ADHS's private-well pamphlet says independent laboratories can test private well water and points well owners to this list; it does not say which labs take samples from well owners.
Before you send a sample, call the lab to confirm it is currently certified for the exact test and method, that it accepts samples from homeowners, and how to collect and ship them. Status can change between list updates.
Why test for VOCs in Arizona
Volatile organic compounds come from fuel, solvents and their breakdown products, and because they evaporate they reach you through the shower as well as the tap. Read our VOCs explainer.
About 218,170 people in Arizona used private wells in 2015, by the USGS estimate of people on domestic self-supplied water. [1] Federal limits are written for public water systems, not private wells, so testing is up to the owner.
For tests that depend on your home (farms nearby, old plumbing, a new baby), use the which-tests checklist. When results arrive, check your numbers against EPA's limits. State guidance, county data and every lab: Arizona.
