Clean Water and Sanitation in the US

By 2030, UN Sustainable Development Goal (SDG) 6, Clean Water and Sanitation, aims to ensure the availability and sustainable management of water and sanitation for all. This includes securing access to safe drinking water, improving water quality and water use efficiency, and protecting and restoring freshwater ecosystems.

In the US, 91% of public water systems are supplied by groundwater, while 68% of the US population use systems supplied by surface water sources such as lakes and rivers. More than 1 million people lack consistent access to safe drinking water, a bathroom, and hot and cold running water.

The drivers behind a person's lack of access to clean water and sanitation services are wide-ranging and include the monetary cost, water sources, and facilities available based on geographic location, government regulations, and more. Lack of access can also impact whole communities. This often occurs more in rural areas than in urban settings, with strong correlations between race and income levels, as well as access to affordable and safe housing. Over 500,000 people experiencing homelessness face challenges with consistent access to water and sanitation resources.
