The department works in many ways to protect Missouri’s water resources. We issue permits, inspect sources of water pollution and analyze water level data. The department provides financial and compliance assistance and, when necessary, enforcement action to address violations of water quality regulations. We work with stakeholders to develop a state water resources plan. We invite you to help us make a difference in protecting Missouri’s water resources.
