The Izaak Walton League empowers volunteers throughout the U.S. to use traditional water monitoring techniques and innovative crowdsourced programs to curb water pollution at the source—whether from urban development, agricultural runoff, road salt or other causes that harm our streams and affect our drinking water.
Our programs and free monitoring test kits make it easy for anyone to start monitoring local waterways.

Meet a Monitor: Grace Corbett
This fall, staff at the Izaak Walton League of America national office had the privilege of working with Grace Corbett, a senior at Nelson County (VA) High School who is enrolled in the Blue Ridge Virginia Governor’s School program. Growing up in a rural area surrounded by rivers and creeks, Grace has always been interested in the relationship between communities and waterways. So, when it came time to choose a topic for her senior capstone project, Grace decided to focus on water pollution.
