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

Elevated groundwater specific conductance is associated with increased total dissolved solids resulting from biodegradation of oil in the subsurface. The waterborne electromagnetic induction data and supporting datasets collected at the Bemidji field site were used to assess belowground areas with elevated specific conductance and determine likely pathways for discharge to surface water at the National Crude Oil Spill Fate and Natural Attenuation Research Site.
