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 and gold); Utah (uranium); Colorado (uranium and gold); Wyoming (uranium and rare earth elements); Montana (copper, silver and gold); Idaho (silver, lead and 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
• Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Investigations
• Surface geophysics, down-hole geophysics/logging and interpretation
• Geologic mapping, data interpretation and modeling
• 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
• Post-operational assessment and monitoring
