Gas ebullition can be a significant mechanism for mass transport of NAPL and other contaminants to the surface water column. Accurate evaluation of the presence and potential of gas ebullition to facilitate NAPL and contaminant migration to the water column is a critical step in contaminated site characterization, conceptual site model development, assessment of remedial alternatives, and sediment remediation design.
The migration of gas bubbles through sediment and surface water is called gas ebullition. Gas ebullition results from the biogenic production of methane and other gases in…read more.
