Which organization is responsible for the regulation of environmental quality in Mississippi?

The Mississippi Department of Environmental Quality is the organization specifically tasked with regulating environmental quality within the state of Mississippi. This agency is responsible for implementing state and federal environmental laws, managing natural resources, and ensuring compliance with environmental regulations.

The agency's roles include monitoring air and water quality, overseeing waste management, and working to mitigate pollution. It plays a crucial part in maintaining and improving the environment, protecting public health, and ensuring sustainable development practices in Mississippi.

Other options listed represent organizations that have related but different responsibilities. For instance, while the U.S. Environmental Protection Agency works at the federal level to regulate environmental standards across the country, it is not focused specifically on state-level enforcement as the Mississippi Department of Environmental Quality is. The Mississippi Water Resources Board primarily deals with the management of water resources and does not encompass the broader environmental regulatory scope, and the Mississippi Geological Survey focuses on geological data and research rather than direct environmental regulation.
