dc.descriptionAbstract: Vapor fortification is a precise treatment method for preparing soil subsamples for the analysis of volatile organic compounds (VOCs). This method of spiking is unique in that the fortification level is soil-type specific and the treatment mechanism is analogous to how soil in the vadose zone becomes contaminated by vapors from liquid VOC point sources. Soil subsamples treated by vapor fortification and sealed in glass ampoules until analysis have shown both good precision within batch and among batches, and analyte concentration stability for a month or longer. Vapor-fortified quality assurance/quality control (QA/QC) soils are more environmentally representative than soils fortified by liquid spiking procedures for the analysis of VOCs in vadose zone samples.-
