Summary:Concerns regarding the movement of the contaminants, particularly in the vapor phase, prompted a site investigation. Part of that investigation included the determination of the permeability of the tuff. Three methods which measure the intrinsic permeability were used—air injection, vacuum testing, and laboratory testing of rock core samples. Dual packers were used to isolate specific zones for the air injection and vacuum tests. Comparison of the results shows that vacuum tests produce results which are in good agreement with the laboratory permeability for unfractured zones. Permeabilities measured with air injection tended to be as much as an order of magnitude higher than the other methods.—Modified journal abstract.
