MINING

The Petrotek Team has over one hundred years of combined experience in performing hydrogeologic characterizations for evaluating soils, ground water/surface water impacts at new and active hard rock mining/mineral processing sites throughout the western United States. We have worked at numerous mining sites in the western US including sites in Arizona (copper); New Mexico (uranium, copper, silver, gold); Utah (uranium); Colorado (uranium and gold); Wyoming (uranium and rare earth elements); Montana (copper, silver, gold); Idaho (silver, lead, zinc) Specific areas of expertise include:  

 

  • Preparation of Permit to Mine Applications
  • Environmental monitoring for active mining operations
  • Investigations to assess source and pathways for Acid Rock Drainage (ARD)
  • Uranium Mill Tailings Remedial Action (UMTRA) Investigations
  • Resource Conservation and Recovery Act (RCRA) Investigations
  • Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Investigations
  • Surface geophysics, down-hole geophysics/logging and interpretation
  • Geologic mapping, data interpretation and modeling
  • Soil boring and monitoring well installation via direct push, auger drilling, air hammer drilling or mud rotary drilling
  • Global Positioning System (GPS) surveys
  • Characterization of aquifer properties via slug tests and single-well or multiple well long-term aquifer tests
  • Groundwater modeling studies to assess long-term mining impacts from baseline pre-mining conditions
  • Groundwater modeling studies for optimization of recovery well systems recovery well / groundwater interception systems
  • Design and installation of recovery well / groundwater interception remediation systems
