Pollution and Water Quality

According to the United Nations, declining water quality has become a global issue of concern as human populations grow, industrial and agricultural activities expand, and climate change threatens to cause major alterations to the hydrological cycle. Resources available in this sub-theme include manuals describing water quality testing and treatment, reports and assessments of water quality from around the world, methods of maintaining water quality and managing pollution, and other resources that support enabling environments for effective water quality control.
