Accidents, spills, leaks and improper waste handling and disposal not only contaminate our air, water and land, but can also pose a threat to the health of Missouri's citizens, visitors and wildlife. The department's goal is to protect human health and the environment from threats posed by the sites. The department performs and oversees environmental investigation and cleanup activities at sites where various wastes have been or could potentially be released into the environment. The department works with responsible parties to return these sites to safe and productive reuse. Learn more about the various types of investigations and cleanups in Missouri. For information about groundwater and gas monitoring at solid waste landfills, visit the department's Solid Waste Landfill Monitoring and Reporting webpage.
