Leigh Creek, SA
Mining & Resources
AWE was engaged by Alinta Energy to assist with groundwater management and dewatering at the Leigh Creek Coal Mine. This involved the review of available hydrogeological data to gain a better understanding of site hydrogeology, particularly the source and timing of groundwater inflows.
The data review led to the development of strategies to control groundwater inflows including an investigative drilling program to implement dewatering, an aquifer testing program and a numerical model to assess the impacts of pumping. Thorough data review with site inspections and field program supervision by experienced hydrogeologists was essential in providing alternative approaches to suit all stakeholders.
