ELEMENTAL COMPOSITION OF COAL AND FLY ASH SAMPLES
Figures 1 and 2 depict the levels of the TCLP elements in the coal and fly ash samples, respectfully.
Cadmium and levels were not determined for the coal and ash samples but were examined in the leachate
analysis. Levels of Hg and Ag are below detection limits for all three varieties of coal and ash. Ba and
Cr are the most dominant TCLP elements in the coal and ash samples. Concentrations are elevated in the
fly ash compared to the coal as expected, most likely due to the high surface area to volume ratio
differences.
