Stream Assessment Training – FREE

Summit Free Public Library 75 Maple Street, Summit, NJ

Unless there's obvious pollution in the river or stream, to the untrained eye, the water may look healthy. But is it? This free training session, led by Sandra LaVigne, GSWA Director of Water Quality Programs, will provide you with all the necessary skills to make your own determinations. An indoor classroom session teaches you how to conduct visual and biological stream assessments, identify macroinvertebrates, and recognize environmental factors that could impact stream health. An outdoor session lets you practice your new-found skills at a local stream site. By afternoon, you will be fully trained in visual and biological stream assessment. And if you are ready to take that next step, consider becoming a stream monitoring volunteer! Tools and supplies will be provided. It gets a little messy so wear your boots and bring clean shoes to change into afterward. Preferred volunteers are 15 or older. This free training session is held in conjunction with the AmeriCorps New Jersey Watershed Ambassador Program.
