Deer Creek Mine – Nevada City, CA

On behalf of the U.S. Department of the Interior, Bureau of Land Management (BLM), H&K teamed with URS Group to perform an Engineering Evaluation / Cost Analysis (EE/CA) and Human and Ecological Risk Assessment (HERA). The EE/CA and HERA evaluated alternative Non-Time-Critical Removal Actions (NTCRAs) for remediation of mine tailings at the Stocking Flat site, in the context of a larger watershed assessment. H&K developed a conceptual model for the site based on the evaluation of previous watershed studies and characterization of potential source areas, including hydraulic mining pits and hard rock gold mining operations in the historic Champion Group of mines.
