Global Water Watch (GWW) is a voluntary network of community based water monitoring (CBWM) groups. The overall goal of GWW is to foster the development of citizen volunteers to monitor surface waters for the improvement of both water quality and public health. GWW helps communities establish teams of citizens who measure physical, chemical and biological indicators of watershed fitness. Monitors use their data to restore streams and lakes, improve drinking water quality and public health, and implement environmental education programs for the public.
