Join Milwaukee Riverkeeper and Riveredge staff to learn how to assess the water quality of a nearby stream or river. Be a hands-on part of citizen science! 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 a statewide website.
