The combined effects of sorption, rate of release and biodegradation tend to affect the plume lengths in the same direction:
- The rate of release of a chemical from the fuel is inversely proportional to its solubility which is usually inversely proportional to the amount of sorption. The MTBE comes out fastest and the xylene takes longer.
- Biodegradation of MTBE is less than that of benzene or xylene, so the MTBE plume is shown extending further from the source
