Figure 5. FID GC profiles from a No. 2 Diesel Standard containing n-alkanes from n-C10 to n-C22 and hexane
extracts of RMA Soil-Amended Basin F sludge from above the liner (sample no. 24216) before and after
stabilization with the DCR process. To facilitate comparison of total resolved hydrocarbons between the RMA
samples, a constant nominal weight (20 g) of sample was extracted with a constant volume (100 mL) of
solvent. Because ADM regular soy soap stock was used to aid in sequestering the pesticides during the DCR
process, a separate chromatogram of the soap stock diluted in methylene chloride is also presented for
reference. All chromatograms were obtained under identical instrument conditions (1.0 L injected; 30 m,
OV-1 narrow bore column; 50C [4 min] then 7C/min to 275C [30 min]; GC attenuation 32 12).
