In the past few years, as hazardous waste sites have been studied more often and in more
detail, immiscible fluids have been encountered in the subsurface with greater frequency …

A summary of geochemical techniques for purposes of determination of a baseline condition
and subsequent monitoring of potential gas microseepage from CO2-EOR or geologic …

A theoretical investigation of factors affecting the gas phase transport of evaporating organic
liquids in the unsaturated zone is presented. Estimates of density‐driven advective gas flow …

Hazardous waste sites and industrial facilities contain area sources of fugitive emissions.
Emission rate measurements or estimates are necessary for air pathway assessments for …

Carbon dioxide sequestration in geologic media is being investigated as a means of
reducing emissions to the atmosphere. Oil and gas fields, which were in production decline …

Results from modeling of microseepage are presented that suggest that under proper
conditions some thermogenic CH4 is transported to the atmosphere without complete …

The multiphase steam injection simulator developed in part 1 (Falta et al., this issue) is used
to simulate two laboratory column steam displacement experiments. In the first simulation …

A newly developed multiphase mixture model is applied to numerically investigate infiltration
and transport of nonaqueous phase liquids (NAPLs) in the unsaturated subsurface …

Measurements of atmospheric methane by the Curiosity rover's SAM-TLS instrument are
providing evidence of seasonality and diurnal variation in concentration. Given methane's …
