Regions of continuous permafrost in the High Arctic are sometimes assumed to be free of risk for acidic drainage and significant metal leaching. Such assumptions arise from the expectation that freezing conditions will halt oxidation and associated reactions. However, laboratory and field studies ha...

Description
Summary:Regions of continuous permafrost in the High Arctic are sometimes assumed to be free of risk for acidic drainage and significant metal leaching. Such assumptions arise from the expectation that freezing conditions will halt oxidation and associated reactions. However, laboratory and field studies have shown for decades that significantly acidic drainage arises in the High Arctic. This Internet Case Study summarizes two recent studies to complement the findings of several others.
