API Groundwater Arsenic Manual: Attenuation of Naturally-Occurring Arsenic at Petroleum Impacted Sites

PUBLICATION 4761    FEBRUARY 2011

This manual:

  • Was developed to explain the mobilization, transport and attenuation mechanisms of naturally-occurring arsenic in groundwater a petroleum impacted sites.
  • Identifies and categorizes the potential sources of arsenic at petroleum impacted sites, including arsenic contained in native rock and soils and arsenic resulting from anthropogenic sources;
  • Provides information on the arsenic content of petroleum and refined products. Arsenic is not a common or significant trace element in petroleum, and petroleum is not known to be a significant source of mobile arsenic in groundwater.
  • Presents the fundamentals of arsenic biogeochemistry at petroleum impacted sites where the presence of hydrocarbons may result in dissolution of native arsenic due primarily to biodegradation and the resulting electrochemically-reduced conditions; and
  • Provides validated tools for the assessment of arsenic at petroleum impacted sites and its management through natural attenuation.

Natural Breakdown of Petroleum Underground Can Lace Arsenic into Groundwater. U.S. Department of the Interior | U.S. Geological Survey, 2015. Web. Accessed January 2015.

"In a long-term field study, U.S. Geological Survey (USGS) and Virginia Tech scientists have found that changes in geochemistry from the natural breakdown of petroleum hydrocarbons underground can promote the chemical release (mobilization) of naturally occurring arsenic into groundwater. This geochemical change can result in potentially significant arsenic groundwater contamination.

Abstract


Focused on the mobilization and attenuation of naturally-occurring arsenic at petroleum impacted sites

Naturally-occurring arsenic may be mobilized into shallow groundwater by inputs of biodegradable organic carbon, including petroleum hydrocarbons.

This manual:

  • Was developed to explain the mobilization, transport and attenuation mechanisms of naturally-occurring arsenic in groundwater at petroleum impacted sites.
  • Identifies and categorizes the potential sources of arsenic at petroleum impacted sites, including arsenic contained in native rock and soils and arsenic resulting from anthropogenic sources;
  • Provides information on the arsenic content of petroleum and refined products. Arsenic is not a common or significant trace element in petroleum, and petroleum is not known to be a significant source of mobile arsenic in groundwater.
  • Presents the fundamentals of arsenic biogeochemistry at petroleum impacted sites where the presence of hydrocarbons may result in dissolution of native arsenic due primarily to biodegradation and the resulting electrochemically-reduced conditions; and
  • Provides validated tools for the assessment of arsenic at petroleum impacted sites and its management through natural attenuation.

A summary paper of this manual was presented at and published in the proceedings of the 2010 Battelle conference (citation below). This summary is available for download below (PDF file).
