Fig. 3. Stacked, chromium K-XANES (X-ray absorption near edge structure) spectra for soil samples collected for a preliminary study (Hesterberg, 2001) at various depths from sampling locations around the incinerator at the Bogue site. A comparison with standards containing 0 or 10 mol % of total Cr as Cr(VI) indicated that <10% of the Cr in the soil samples was Cr(VI). Samples designated as Bo4*, Bo7*, and Bo8* correspond to samples listed in Tables 1 and 2 that were in closest proximity.
