Summary

The National Crude Oil Spill Fate and Natural Attenuation Research Site is located near Bemidji, MN, USA. A high pressure oil pipeline ruptured in 1979 releasing ~1.7 million liters of light crude oil, which sprayed over an area of ~6500 square meters and collected in topographic depressions. Approximately 75% of the spilled oil was recovered. Much of the remainder reached the water table, where it is distributed into three residual oil bodies (the north, middle, and south oil pools). Groundwater flows east-northeast toward a small lake roughly 300 m downgradient from the original spill site. Secondary reactions of sediments with byproducts from anaerobic degradation of the oil plumes cause increases in total dissolved solids, which [...]

Purpose

The waterborne electromagnetic induction data and supporting datasets collected at Bemidji were mainly used to map where an elevated specific conductance plume, associated with biodegradation of oil at the National Crude Oil Spill Fate and Natural Attenuation Research Site, is discharging to surface water.
