Abstract
Coal combustion byproduct (CCB) leachate can contain elevated concentrations of dissolved metals, and in some Appalachian landfill settings may be co-mingled with metals-bearing mine drainage, requiring treatment to meet regulatory discharge standards. These metals can be removed passively by combinations of oxidation/precipitation basins, surface flow wetlands, vertical flow wetlands, and manganese-oxidizing bacteria systems. Design approaches are presented for passive treatment systems currently constructed or under development at five CCB landfill sites, variously treating aluminum, arsenic, hexavalent chromium, iron, manganese, and selenium.
