List of Arizona Certified Commercial Drinking Water Laboratories



The following commercial laboratories are licensed by the Office of Laboratory Services to perform drinking water testing for Arizona .  The list contains the laboratories current contact information.  Please note that not all commercial laboratories perform all drinking water testing.  This list is current as of end of business Sunday, April 30, 2017 and is updated on a 24 hour basis by the Department.


Arizona offers in-state laboratories the option to license multiple laboratories under a single license number. Therefore if you see the same laboratory name located in the same city with different area codes and phone numbers it means that only one of the laboratories is located in the city listed and the other is located in another part of the state.

All laboratories licensed by Arizona are inspected on a routine basis.  Inspection reports and responses are available for review by contacting our office.

If you are interested in obtaining a list of laboratories that perform testing in additional matrices or need additional information, please contact our Office at (602) 364-0720.
