Based on all of the data, McLin concluded that there was little to no correlation between values for CO2 flux and known or postulated faults, and between the CO2 flux and the shallow thermal anomaly. Instead, the flux values appeared to depict a completely random pattern throughout the study area. Notably, absolute values for CO2 flux were elevated throughout the surveyed areas (McLin, 2004). A possible explanation not considered by McLin, is that the generally random but uniform CO2 flux could represent leakage from the massively fractured subsurface formations delineated in the final reflection seismic traverses completed in 2004 after the gradient holes were drilled. If this is a correct assessment, then it is unlikely that a single major fault or faults could provide the vertical conduit for CO2; instead, vertical leakage could occur ubiquitously through the soil overburden.
