Geochemical Indicators of Anaerobic Biodegradation of BTEX

摘要

A pipeline leak released refined petroleum to the subsurface at a Kansas floodplain site. Variable depth cluster wells from the water table to the bottom of the aquifer and single wells screened across the contaminated interval were installed at the site. Dissolved concentrations of alkylbenzenes, methane oxygen, and organic acids were used to locate what parts of the subsurface have acclimated to anaerobic biodegradation. Natural biological weathering has occurred at the site. Most predominant was that major fractions of the contaminant mass was removed by passive bioremediation.
