Description: CRREL Report
Abstract: This study compares aqueous extraction-headspace/Gas Chromatography (GC) and the EPA SW-846 purge and-trap–gas chromatography/mass spectrometry (Method 8240) for the determination of four common Volatile Organic Compounds (VOCs) in soils. Comparisons were made on two fortified soils and two contaminated field soils. In only two of the cases were consistent significant differences found—for the two most hydrophobic compounds in a high organic carbon soil, and for TCE in a field-contaminated soil that had previously shown slow aqueous VOC desorption. The findings strongly suggest that aqueous extraction-headspace/GC can be used not only to screen soils for VOCs giving same-day results, but often will provide results not significantly different from current laboratory based measurements.
