In June 2013, the EPBC Act was amended to capture water resources as Matters of National Environmental Significance (MNES). Under the amendment, water resources included groundwater and surface water, and organisms and ecosystems that depend on it to maintain ecological function and condition. These ecosystems are otherwise termed groundwater dependent ecosystems or GDEs. In December 2016, Queensland made amendments to the Water Act and the Mineral Resources Act 1989, expanding the scope of environmental impact assessment from groundwater springs alone to include assessment of impacts to all ecosystems that rely either entirely or intermittently on groundwater. 3d Environmental has specialist knowledge in the classification and assessment of GDEs to meet project regulatory requirements and assist ecologically sensitive project design.
