Ethanol-Containing Fuel Spills Enhanced Natural Trace Element Release from Sediments in an Experimental Setting

Release Date:

Experimental field research simulating hydrocarbon spills by researchers from the USGS (including RBPGL), Virginia Tech, and the University of St. Thomas showed that mixed ethanol and petroleum-based fuels increased the rate by which arsenic and other natural trace elements are released from aquifer sediments to groundwater when compared to petroleum-based fuels alone.

A scientist collects a groundwater sample to analyze for arsenic and other chemicals from a well installed in a wetland at the National Crude Oil Spill Fate and Natural Attenuation Research Site, near Bemidji, Minnesota. Researchers collected samples over a two-month period to quantify rates of arsenic release from aquifer sediments as organic carbon in the form of petroleum byproducts and ethanol biodegraded in the aquifer. (Credit: Jennifer T.
