Highly acidic and metal-rich runoff from coal storage facilities can have a dramatic
impact on local surface and ground water quality. In order to identify important reactions
governing metal transport within subsurface environments subject to infiltration
of coal pile runoff, samples of uncontaminated subsoil and aquifer materials
adjacent to the D-Area coal stockpile runoff containment basin at the Department of
Energy's Savannah River Site were collected and subjected to leaching with the
acidic, metalliferous coal pile runoff. Columns were packed to bulk densities of 1.5
Mg m-3 and subjected to steady, saturated flows of 0.2 and 1.3 cm h-l, Effluent was
collected and multicomponent transport through the subsoil and aquifer materials
evaluated. Observed transport was then related to soil chemical and mineralogical
properties. Mass balance calculations, a sequential dissolution scheme in which column
leaching was terminated and elements partitioned to aqueous, M NH4CI, and
ammonium oxalate in the dark (Ox)-extractable phases, and mineralogical and surface
chemical analyses were used to identify important chemical processes and
