Water Quality and Storage

According to the Centers for Disease Control, because contaminated water is a major cause of illness and death, water quality is a determining factor in human poverty, education, and economic opportunities. Unfortunately, worldwide water quality is declining, threatening the health of ecosystems and humans worldwide. Safe water storage is also integral to ensuring water quality. Resources available in this sub-theme include guidance on maintenance for water tank storage, country water quality assessments, among other resources that support WASH storage and water quality.
