Trona Mine Dewatering
Hydro Geo Chem evaluated dewatering alternatives for a large, underground trona mine in Wyoming.

Hydroelectric Pump Back Project
High groundwater inflows were encountered during tunnel construction through fractured granitic rocks, requiring expensive dewatering far in excess of that anticipated during project planning.

Evaluation and Impact of Waste Water Handling Practices at a Trona Processing Plant
Waste water handling practices at a trona processing plant had created a brine plume in a fractured bedrock aquifer that discharged into a nearby river.

Reclamation of Acid Mine Water Contamination
A 28-mile-long shoestring alluvial aquifer contains a 7-mile-long plume of metals and acid resulting from seepage from historical mining operations.

Investigation and Design Assistance, Flue Gas Desulfurization Ponds
Several holding ponds, including a 40-acre flue gas desulfurization (FGD) pond, had leaked into aquifers underlying a coal-fired power plant.

Simulation of Groundwater Flow through a Tertiary Fanglomerate Aquifer
Groundwater resources in a tertiary fanglomerate aquifer were potentially affected by remedial groundwater pumping.

Copper Mine and Mill Tailings Characterization and Seepage Analysis
An assessment of the potential groundwater quality impacts of drainage from over 2 square miles of copper mine and mill tailings was required for permitting mine operations.
