Hydraulic Impacts of Quarries and Gravel Pits

This is an electronic version of a publication prepared by the DNR Division of Waters. This report is intended to help local officials, the public, and the mining industry understand the main issues surrounding mine establishment and to provide suggestions for monitoring and mitigation strategies to prevent significant impacts on water resource. The research provides the first comprehensive assessment of aggregate mining impacts on ground-water systems in Minnesota. This information can be used for siting of new aggregate mines and for more accurately assessing their impacts on local ground-water resources. It can also be used for planning purposes at the state and local level.
