dc.description.abstract | Alaska fuel-storage facilities are required by law to provide secondary containment for their largest tank-volume. Secondary containment commonly includes berms, catchment basins and ditches. Fuel-penetration rates on site soils are needed to predict potential fuel-penetration depths. Field and lab tests quantified fuel-penetration rates for three site soils in Bethel, Alaska. In-situ tests following ASTM D 5093-90 allowed measurement of fuel infiltration rates using a falling-head permeameter allowed quantification of hydraulic conductivities, permeabilities and infiltration rates in frozen and unfrozen soils prepared at various moisture contents. Unfrozen samples were tested at room temperature, 19.8-24.0C̊ (67.6-75.2F̊). Fuel-penetration rates were similar regardless of moisture contents. Tests for frozen samples occurred at -4C̊ (25F̊). Fuel-penetration rates decreased as ice-saturation increased. The permeant used for each test was a Diesel #2/Jet A-50 fuel mixture (heating fuel) consisting of predominately Jet A-50. | en_US |
