The Wisconsin Department of Natural Resources accredits laboratories to perform aqueous (non-potable water), solid and drinking water testing for many of the agency’s environmental programs. Certified and registered laboratories must meet all the criteria outlined in Ch. NR 149, Wis. Adm. Code.

Beginning October 29, 2019, there are now two options available for PFAS accreditation of laboratories in Wisconsin.

Detailed information regarding the testing methods and accreditation application is available at the laboratory certification web page.

Questions regarding PFAS accreditation may be directed to Tom Trainor, 920-412-5970.
