Laboratory Certification

Part of the Wisconsin State Laboratory of Hygiene

[State Seal]

The Wisconsin State Laboratory of Hygiene is certified by the Wisconsin Department of Natural Resources (WDNR) and the Environmental Protection Agency on an annual basis. The EPA certifies the laboratory for the Safe Drinking Water Act including EPA methods 507, and 524.2.

The (WDNR) certifies the WSLH under the provisions of the Wisconsin Administrative Code, ch. NR 149 for a number of environmental parameters. The Inorganic Chemistry Unit performs testing on the following certified parameters:
