Field detection of volatile organic vapors from soil and water matrices
The collection of subsurface soil or sediment samples in survey or screening studies for subsequent volatile organic analysis in the laboratory introduces many considerations including the number of samples to be collected along a depth profile, which subsample to submit, and what treatment and preservation are ideal before sample analysis. Ideally, the sample with the greatest probability for confirming a leaking tank or a spill site would reduce project costs considerably. Using a field compatible photoionization detector, a series of studies using xylene, benzene, and trichloroethylene contaminated soils or water placed in small chambers under temperature control were conducted to simulate field situations. The water contamination study was designed to mimic sampling well headspace for the presence of volatile organic compounds. The results have provided a basis for field screening and sample selection for soils containing volatile organic contaminants and identified some important considerations for screening well headspaces for organic contamination. 4 refs., 7 figs., 4 tabs.
