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.
