This February 2011 report is 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.
This manual:
- 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.
