Stormwater and Septic Leachate Toxics Reduction Grant Program

About the Program

The Western Montana Conservation Commission (WMCC) and the Montana Department of Natural Resources and Conservation (DNRC) aim to address the escalating challenges posed by toxic pollution in western Montana’s watersheds, the headwaters of the Columbia River Basin. With rapid population growth and urbanization in the region, there’s an urgent need to mitigate the adverse effects of toxic pollution on water quality.
