More people die from poor quality water annually than from all forms of violence, including war.

As water quality declines, more than 50% of freshwater fish species are at risk of extinction.

Up to 30% of the nitrogen that is used in modern agriculture ends up in our fresh water.


A 300% rise in phosphates has led to an increase in algal blooms which can damage human health.

You can make the difference. Join our global community of citizen scientists to help promote freshwater sustainability.
