Water is one of Missouri’s most abundant and precious resources. Our plentiful streams, rivers, lakes and groundwater are critically important natural resources. We help protect our surface water and groundwater by monitoring its quality and quantity as we work with citizens, industry and government to ensure Missouri water is abundant and safe to use. One way is by ensuring compliance with the federal Clean Water Act by implementing the Missouri Clean Water Law. Some of the key activities the department carries out to protect and improve water quality include developing standards, issuing permits, conducting inspections and enforcement actions, monitoring water quality and quantity, developing plans to improve water quality and providing funding to communities to upgrade their infrastructure.
