Global Water Quality Insights

The following interactive data visualizations are curated from a variety of global sources, including GEMStat, WHO, and UNICEF. They explore key dimensions of water quality such as nutrient and organic pollution, pH variation, transparency in data reporting, and public health impacts. Together, they offer insight into the state of freshwater systems around the world and their connection to environmental and human well-being.
