In 2015 the United Nations General Assembly adopted 17 sustainable development goals designed to transform our world by 2030. The sixth goal is to ensure the availability and sustainable management of water and sanitation for all. According to the United Nations, one in three people live without sanitation. A lack of sanitation and sanitary waste management systems can reduce a community's access to clean water, and lack of access to clean water can allow diseases to run rampant, sometimes creating epidemics of water-borne infectious agents. Learning about how freshwater systems work in the wilderness, rural communities, and urban centers can help us better understand the challenges of providing clean water and sanitation to people around the world.
