Impacts of mining on water quality and mahinga kai.
Extraction of minerals can cause large changes to the landscape, and both surface and groundwater may be significantly impacted by mine leachate, increased erosion and sedimentation, and the mine operations themselves. The hydrology of streams may be altered by flow diversions employed during alluvial and underground mining.
