This document details the impacts of underground mining on groundwater and wetland systems, specifically the formation of a dewatering cone that reduces wetland recharge and affects community water supplies. It lists mitigation measures for both active mining (monitoring, grouting, and cover drilling) and post-mining phases (monitoring mine voids and treating decant water).

• Underground mining activities and voids are identified as causing a cone of groundwater draw down that can affect multiple wetland systems, seep wetlands, and channel valley bottoms. This process leads to the formation of a groundwater cone of dewatering, which reduces the recharge of wetland resources and can negatively impact communities that rely on surface and groundwater as their primary water supply.
• To mitigate the impacts of underground mining on groundwater and wetlands, the document specifies several operational measures: monitoring the volume and quality of water inflow into mine workings, monitoring groundwater levels, grouting excessive inflows, and using cover drilling to identify and pre-grout zones of potential high inflow. Additionally, the reporting of all incidents and the paving of roads where feasible are listed as mitigation steps.
• Post-mining mitigation focuses on the recovery of the groundwater draw down cone. Required actions include monitoring groundwater levels and quality, specifically including water within mine voids, and the treatment and release of decant water from underground workings.
