About this map
The Montana Department of Environmental Quality (DEQ) has developed an interactive web mapping application that allows its users to explore data collected and managed by the Department in support of its mission..."to protect, sustain, and improve a clean and healthful environment to benefit present and future generations." Not all data managed by DEQ is available as a layer within this map.
If this is your first time using this map please check out the Help to understand its functionality.
To better understand the many layers of information made available to you in this map please check out the Legend.
Please find more information about all of DEQ's Bureaus via our Montana DEQ website and if you have any questions please feel free to Contact Us.

NOTE: Underground Storage Tanks, Petroleum Fund Claims, and Unpermitted Releases are not current and have not been updated since December 2018. These datasets have moved to a new system, and are not included in the current Data Search Tool application. The new versions of these datasets are planned to be part of a replacement application that will be available in the second quarter of 2020.
