Abstract
High iron concentrations in the leachate plume of the KL Landfill in Kalamazoo County, Michigan, persist in the presence of detectable hydrogen-sulfide. Under these conditions iron-sulfide minerals are highly oversaturated and should be precipitating. Calculations performed by the chemical equilibrium model WATEQF indicate over-saturation of selected iron-oxides, siderite, and iron-sulfides. Semilog plots of iron concentration versus time of exposure to air demonstrate retarded precipitation of ferric hydroxide, and analytical techniques of ion chromatography, Fourier transform IR spectrophotometry (FTIR), and UV-Visible spectrophotometry have yielded results which indicate that organic complexing of ferrous iron plays a significant role in the mobility of iron detected in the KL Landfill leachate plume.
