24 MINING & TECHNOLOGY AUSTRALIA 2014 | ISSUE 8 TECHNOLOGY & INNOVATION Australia has in fact led the world in the use of sophisticated water metrics and benchmarking through a "Water Accounting Framework" developed by the Minerals Council of Australia (MCA) and the Sustainable Minerals Institute at the University of Queensland. While not fully adopted by all MCA's member companies so far – the MCA is currently reviewing coverage – the Framework has helped usher in a growing acceptance of water 'inventories' to beter quantify inputs, outputs, risks, quality, quantity and outcomes. For companies like MMG, Newcrest & BHP Billiton who have led adoption of the Framework, its meant a comprehensive, long term approach to cost efective, sustainable solutions based on a mix of technologies, systems and processes. It's also meant that the range of scientifc, business and technological knowledge being tapped at mines, including hydrological, geotechnical, geochemical, environmental and water treatment, has jumped exponentially. A number of miners are now on board. Centennial Coal, who operates mines in NSW, is continuing to work with global engineering and environmental consultants GHD to assess water management capabilities at its mines based on detailed water balances and groundwater modeling to fnd efciencies and minimize environmental impacts. BHP Billiton's "Pilbara Water Resource Management Plan" is also a holistic, scalable water planning tool providing "transparency on water management criteria, controls, core requirements and water licences", a framework the company says "has resulted in direct commercial, technical, operational, environmental and approval benefits." While QGC, a natural gas explorer and producer in Queensland, has implemented a formal Water Monitoring & Management Plan detailing their water infrastructure, monitoring programs and data gathering, modeling, analysis and interpretation activities. EarthSystems is another Australian consulting company who says a much broader, more detailed water inventory is the way to get the long term operational and sustainable systems right, calling for more miners to take what they call a geochemical engineering approach to water. For EarthSystems water specialist, Bret Davis, many of the problems mine's face on water could have been avoided with more forethought and planning. "An issue like closure may seem a long way of, but should be planned for right from the start and ft within the whole water management strategy so that design, infrastructure or materials handling work toward the best outcomes long term," Davis said.
