A spill from a gasoline tank releases benzene, toluene, ethylene, and xylene (BTEX) and methyl-tertiary butyl ether (MTBE) into the subsurface. The spill travels through the vadose zone and into the saturated zone. The Kow of the BTEX compounds is higher than the Kowof MTBE. What is the significance of the Kow in this scenario? How do we obtain the Kow information? Will the MTBE plume or the BTEX plume travel further into the saturated zone? Why?
