Abstract:

The effect of freezing on the distribution and movement of four volatile organic compounds was studied in a silty soil. Eight polycarbonate test tubes were filled with spiked saturated soil. The soil was frozen half way up in four of the tubes the other four were controls and were not frozen. We found that freezing a water-saturated silt spiked with chloroform, benzene, toluene, or tetrachloroethylene did not move the organics ahead of the freezing front, but rather that freezing retarded the volatilization of each organic in the frozen soil relative to the unfrozen soil. Keywords Benzene, Chloroform, Freezing, Silty soil, Tetrachloroethylene, Toluene, Volatile organics.
