New water monitoring technologies such as pressure and acoustic wireless sensors with cloud-based computing track the integrity of water supply networks.
Our nation's waters are monitored by state, federal, and local agencies, universities and volunteers.
Water quality data is used to characterize waters, identify trends over time, identify emerging problems, determine whether pollution control programs are working, help direct pollution control efforts to where they are most needed, and respond to emergencies such as floods and spills.
The world first celebrated World Water Monitoring Day in 2003, today, the program has become the World Water Monitoring Challenge (WWMC). The WWMC builds public awareness and involvement in protecting water resources around the world by engaging citizens to conduct basic monitoring of their local water bodies.
