Negative pH and Extremely Acidic Mine Waters from Iron Mountain, California
Extremely acidic mine waters with pH values as low as −3.6, total dissolved metal concentrations as high as 200 g/L, and sulfate concentrations as high as 760 g/L, have been encountered undergroundExpand

Removal of agricultural nitrate from tile-drainage effluent water using in-line bioreactors
Abstract Two 200-L fixed-bed bioreactors, containing porous-medium material of coarse sand and organic carbon (tree bark, wood chips and leaf compost), were used to treat NO 3 contamination fromExpand

The pore-water geochemistry and the mineralogy of the vadose zone of sulfide tailings, Waite Amulet, Quebec, Canada
Low-pH waters, requiring treatment because of high concentrations of dissolved metals, are being discharged from a decommissioned tailings impoundment at the former Waite Amulet ZnCu mine inExpand

Geochemistry of a Permeable Reactive Barrier for Metals and Acid Mine Drainage
A permeable reactive barrier, designed to remove metals and generate alkalinity by promoting sulfate reduction and metal sulfide precipitation, was installed in August 1995 into an aquifer containingExpand
