;
Undisturbed cores of ashes from the sites, randomly selected in the Old and New ash disposal basins, located in D-area on the Savannah River Plant were removed and sequentially extracted for the quantitative estimation of dissolved (pore water), exchangeable and Fe/Mn oxide associated trace inorganic contaminants (i.e., As, Cd, Cr, and Ni). The Ash samples were also analyzed for total P, K, Na, Ca, Mg, Al, Pb, Mn, Fe, B, Cu, Zn, and Mo. Sluiced water samples, at four locations in the new ash disposal basin, were tested for As, Ca, Cd, Cr, Fe, Mn, and Ni. Ground water samples from the bores, installed at the ash sampling sites were tested for As, Ca, Cd, Cr, Fe, Mn, and Ni. A very small fraction of the total elemental concentration, excepting Cd, were found in the dissolved phase. Most of the easily releasable elements in the ashes were found associated with Fe/Mn oxides. Analysis of the data clearly indicates the release and mobilization of trace contaminants to the lower horizons of the impounded ashes. Elemental translocation was found to be more serious in the old ash basins rather than the new ones.
