13. ABSTRACT (Maximum 200 words)
Traditionally, soil samples obtained for characterizing or monitoring sites for volatile organic compounds (VOCs)
have been transported off site before initiating the preparation steps necessary for analysis. In the most recent
regulatory guidance, only a two-day holding period at 4 2C is recommended before a sample should be pre-
served, so as to allow storage up to 14 days prior to instrumental analysis. The transportation and storage of soil
samples were evaluated for (1) covered core barrel liners, (2) En Core samplers, and (3) empty volatile organic
analysis (VOA) vials under different conditions. Core barrel liners covered with either of two formulations of
Teflon sheeting or aluminum foil failed to prevent rapid losses of VOCs. En Core samplers and otherwise empty
VOA vials were suitable transportation and storage chambers for samples. These chambers not only meet the
initial requirement to retain VOCs for two days when held at 4 2C for transportation purposes, but frequently
showed no significant loss of VOCs after placing in a freezer and storing at 12 3C for an additional 12 days.
