Environmental Impact and Risk Assessment

Waste products resulting from mineral extraction and processing play a crucial role in environmental impact. Among these, surface water and groundwater containing residual chemicals and oxidized minerals stand out as primary concerns, posing risks to both the environment and human well-being. The presence of acidic waters not only inhibits plant growth but also affects aquatic organisms, rendering them unsuitable for drinking or irrigation purposes.

In adherence to government permitting and regulations, strict compliance with environmental policies is mandated throughout the entire lifecycle of any mining site. At WST, we collaborate directly with mining companies to ensure adherence to regulatory reporting requirements and address environmental concerns effectively. Our approach includes the implementation of long-term groundwater monitoring systems, which continuously gather data on water levels and quality throughout the mine’s lifecycle.

Collected field data undergoes thorough analysis, management, and reporting in accordance with regulatory specifications through a comprehensive information management system. To identify and assess potential off-site impacts, we employ sophisticated three-dimensional groundwater flow and transport models, coupled with rigorous aqueous geochemical analysis. Through these measures, we aim to mitigate environmental risks and uphold responsible mining practices aligned with evolving ESG policies.
