Contaminated Sediment Removed from Reservoir at Remote Active Mine Site

White Lake Dock & Dredging, Inc. (WLDD), a division of ENTACT, LLC, conducted mechanical dredging of more than 120,000 cubic yards of contaminated sediments from a remote reservoir within an active mining operation. The client had water quality issues due to uncontrolled reservoir sediment that threatened the mining operation.

The project’s remote location required the construction of access roadways, mobilization of equipment in a mountainous environment, transportation, and disposition of sediments with grades upwards of 17%, and unpredictable weather, including regular flooding of the reservoir with overnight water elevation gains upwards of 30 feet. All sediments were disposed of within the active mining operation and managed to minimize space requirements and water generation.
