Water is a vital, shared resource that is integral to the lives and livelihoods of those communities surrounding QIT Madagascar Minerals (QMM) operations, and to the region’s long-term environmental stability. Access to clean drinking water is also a fundamental human right.
We take our responsibility to manage water very seriously.
Our water strategy provides an integrated approach to managing QMM’s current and future water-related challenges and objectives, across 3 pillars:
In accordance with our commitment to transparently share information, we’ve published our 2024 Water Report, which sets out QMM’s water management data and performance and builds on the 2023 Water Report. Conclusions drawn from the 2024 Water Report remain consistent with the previous 2023 Water Report. Comparison of water quality monitoring data upstream and downstream of the QMM release point shows them to be comparable, with the majority of the regulated metals tested consistently below laboratory limits of detection. The water treatment plant is working as designed, and helping QMM to meet regulatory requirements. Water management requires continual evaluation and analysis to ensure that we avoid and mitigate potential impacts of our operations and implement leading practice. Together with our stakeholders, QMM is committed to continue developing solutions that work long-term.
We conduct an extensive monitoring program on water quality within the mine lease area and around Mandena, in compliance with regulatory requirements. We also conduct additional monitoring and sampling of groundwater, surface water, and marine water quality for the Port of Ehoala’s activities as part of this program.
In addition to QMM’s approved release point (WMC603), 2 sampling stations in the Mandromondromotra River have been selected to represent river quality data upstream and downstream of the approved release point. The map below shows the sampling station locations:
The communities where we operate are central to our water management strategy and sustainable mining vision. We are implementing a community-centred water monitoring approach focused on:
