RBPGL Helps Identify Crude-oil Metabolites in Subsurface Plumes
USGS scientists are studying two subsurface crude-oil spill sites in Minnesota measured concentrations of oil breakdown products (metabolites) at greater concentrations than parent compound concentrations.
At sites where there have been crude-oil or petroleum hydrocarbon fuel spills and contaminants have entered groundwater, metabolites from the crude oil form primarily from biodegradation reactions. The metabolites are more soluble than the parent compounds and are transported from the original source, forming a groundwater plume.
