Paper presented at the BGA 3rd International Conference in Geoenvironmental Engineering. This chapter reports on a series of optical tests which use an artificial sand to directly observe the growth and migration of gas bubbles for different injection rates, pore water pressure, injection point and soil hetereogeneity. The results can be used to predict airflow patterns for soil column and field studies and potential effects on groundwater flow for in-situ bioremediation.
