Abstract
Four analytical methods were compared for estimating concentrations of fuel contaminants in subsurface core samples. The methods were total organic carbon, chemical oxygen demand, oil and grease, and a solvent extraction of fuel hydrocarbons combined with a gas chromatographic technique. Presently the most applicable and convenient technique, based on greatest apparent contaminant recovery, is the solvent extraction gas chromatographic method. Sample heterogeneity and opportunity for losses due to contaminant volatility require considerations during sample handling, analysis, and when interpreting analytical data.
