FLOW volunteers annually monitor the stream water quality of selected Olentangy River tributaries. Volunteer teams measure physical, chemical and biological attributes, including the presence of various “macroinvertebrates “, (insects and other small animals that indicate the level of water pollution). Training sessions are held in May, with testing starting June 15 through September. Please contact FLOW if you’re interested in joining us!
