Abstract
Open pit mining below the water table results in pit lakes. This study documents the current level of understanding of issues concerning pit water quality and determines where additional research is needed. The report discusses factors contributing to pit water quality: groundwater flow, water-wall rock reactions (flow in structures and sloughing of wallrocks), acid versus alkaline pit water (the acid forming process, neutralization, evaluation, of potential for acid production, and mitigation of acid mine drainage), trace elements, arsenic speciation, evapconcentration, and hydrothermal activity.
