Description:
This report is a comprehensive literature review that presents and assesses research results that pertain to the problems and inconsistencies observed in the sampling and analysis of soil volatile organic compounds (VOC) by SW-846 method 5030 (purge and trap) for sample preparation and extraction and methods 8240/8260 (gas chromatography/mass spectrometry) for sample analysis. opics discussed include: interphase transfer mechanisms for VOCs in soil, soil VOC degradation processes, movement of VOCs in the vadose zone, models used for predicting the movement and fate of soil VOCS, soil sampling and preservation methods, analytical methodologies, field methods for determining soil gas and soil VOCS, as well as presenting the author's view of future research needs in the area of soil VOCS. he results and discussion presented in the report are intended to be used to evaluate problems with the current SW-846 methods and as guidance for research needed to formulate procedures that will increase the precision and accuracy of vadose zone VOC measurements.
