Join Milwaukee Riverkeeper and Riveredge staff to learn how to assess the water quality of a nearby stream or river. You’ll find out how to identify aquatic invertebrates and do five water quality tests. Monitors are asked to conduct tests monthly during the summer and submit their data to the statewide Water Action Volunteers website. Masks are required indoors.

Ages 16+ | Free Program | $5 donation appreciated
