Information on the UNICEF website pertains to water issues. Among the content on this site includes curriculum materials for K-12 learning environments and reports about water, environmental and sanitation issues worldwide.

The opening paragraph on the homepage of the Water, Environment and Sanitation part of the UNICEF site reads:

More than 2.6 billion people – forty per cent of the world’s population – lack basic sanitation facilities, and over one billion people still use unsafe drinking water sources. As a result, thousands of children die every day from diarrhoea and other water-, sanitation- and hygiene-related diseases and many more suffer and are weakened by illness.
