Geochemical Characterization Plus ML/ARD Prediction Service
Companies around the world that develop, operate or decommission projects, frequently encounter and require expertise in predicting, assessing and providing solutions to changes in water quality. These potential or real changes in water quality involve water mixing and/or water-rock or water-soil interactions. Rescan provides specialty services in environmental geochemistry that can address these needs.
For mining and mineral exploration companies in particular, mine drainage water quality caused by metal leaching and acid rock drainage (ML/ARD) is of critical importance as mining projects must meet stringent local, regional, national or international water quality standards. Significant ML/ARD remains the most significant issue due to high metal concentrations and the costs of prevention, mitigation and treatment, which may last in-perpetuity.
Rescan’s knowledgeable and experienced environmental geochemistry team can assist clients in developing cost-effective solutions to mine drainage issues. Our services address all stages of the mine life cycle and include:
- Design and implementation of field assessments and monitoring;
- Design and Implementation of waste characterization programs;
- Evaluation of the ML/ARD potential;
- Integration of geochemical characterization into mine planning;
- Water balance and water quality modeling for waste management planning and effects assessment;
- Pit lake modeling;
- Assessment of prevention and mitigation effectiveness;
- Site-wide source contribution and contaminant load balances;
- Assessment of mine closure options;
- Prevention, mitigation and treatment options alternatives analysis; and
- Regulatory and stakeholder consultation.
Rescan’s expertise in environmental geochemistry has also provided services and solutions to other private and public sector clients on projects such as road and power line construction, industrial sites, contaminated sites, and abandoned mines.
