Our mission is to champion a healthy environment for a thriving Montana.

The Montana Department of Environmental Quality (DEQ) is the agency charged with protecting a clean and healthful environment, as guaranteed by the State Constitution. The DEQ accomplishes this by closely monitoring environmental conditions and taking proactive measures to preserve and improve the quality of these natural resources. We make our decisions by incorporating information from our citizens with scientific research and analysis, to ensure we’re serving the public interest and making efficient use of the funds entrusted to us. Our ultimate goal is to protect public health and to maintain Montana’s un- paralleled quality of life for current and future generations.
