GeochemicalProjects

Project: Arsenic, Nitrate and Cyanide Fate and Transport, Lead, South Dakota

Client: Wharf Resources

Scope: Numerical model of contaminant transport utilizing water-rock interaction geochemistry, laboratory determination of attenuation characteristics, identify engineering option for waste disposal and support for permitting

Project: Aqueous Geochemistry of Ortiz Mine Pit Recharge, New Mexico

Client: LAC Minerals

Scope: Numerical model of pit lake recharge to quantitatively describe recharge rate and solution composition. Included field inspection and development of water-rock interaction parameters

Project: Geochemistry of the Golden Sunlight Mine, Montana

Client: State of Montana Dept. of Environmental Quality

Scope: Produced a coupled geochemical/hydrological model to predict long-term meteoric water infiltration of waste rock dumps and potential migration of products of sulfide mineral oxidation for overall impact analysis associated with action alternatives

Project: Kinetics of Chrysocolla Dissolution, Tucson, Arizona

Client: BHP Copper

Scope: Experimental study to produce a rate law for dissolution of chrysocolla as part of overall technology development for in situ leaching project

Project: Regional Aqueous Geochemistry, Cripple Creek, CO

Client: Cripple Creek & Victor Mining

Scope: Team member of on-going effort to develop a coupled geochemical/hydrological model to assess potential impacts on region water in response to anticipated mine expansion

Project: Copper Geochemistry of the Ferris-Haggerty Mine, WY

Client: Wyoming Department of Environmental Quality, Abandoned Mine Lands

Scope: Evaluated geochemical mobilization and transport of copper from abandoned mine throughout local drainage system. Based on geochemical evaluation, produced alternatives for engineered remediation of the site.

Project: Acid Sulfate Solution Interaction with Calcareous Sediment

Client: Kennecott Utah Copper

Scope: Performed field, laboratory and computation studies to establish fundamentals of acid neutralization, metal attenuation/release, sulfate and chloride migration in support of transport models and impact analysis.
