Investigating the health of global

freshwater ecosystems

FreshWater Watch

A global citizen science project from Earthwatch Europe.

It has never been so important to protect our freshwater resources.

Nearly all freshwater environments are impacted by man-made pollutants and by 2050 nearly half of the world's population will be living in areas where water is scarce.

We created FreshWater Watch so that everyone across the globe can monitor the health of the lakes, rivers, streams, wetlands and reservoirs upon which we all depend.
