For What Testing Is Certification Required?

Laboratories (both in-state and out-of-state) performing chemical and toxicological testing for compliance monitoring under many of the Department's covered programs are required to be certified or registered under ch. NR 149, Wis. Adm. Code.

This requirement applies to any laboratory that performs testing in the general areas listed to the right. The table below lists the specific adminstrative codes that require DNR certification or registration. The Department of Agriculture, Trade and Consumer Protection (DATCP) certifies laboratories for microbiological testing in both water and milk. Contact Laura Traas at (414) 760-1364 for more information about the micro testing program.

Contact the Wisconsin DNR if you have questions about whether or not your laboratory needs to be certified or registered.

Programs Requiring Certification:

A laboratory must be certified or registered before doing analysis for clients submitting data to these covered Wisconsin programs. Submitting the application form or passing the reference samples does not constitute certification or registration.

The programs above are established under

WI DNR certification or registration encompasses most matrices and applies to most WI DNR programs; including, but not exclusively, Safe Drinking Water, Wastewater, Groundwater and Soils and Sediment.

The LC&R Program also certifies and registers laboratories for chemical and acute/chronic toxicity analysis. A list of available tests (parameters) and how they fit into the program's category structure can be found here.

The Laboratory Certification Program does not certifiy laboratories for testing under the Clean Air Act or other required air monitoring, radiological or microbiological testing.
