3453 Guidance on petroleum hydrocarbon forensic chemistry for site investigation and remediation Volume 2

Overview:

This publication provides a practical introductory guide to petroleum hydrocarbon forensic chemistry, including a summary of changes in fuel specification and additives over time, the differences between petrogenic and non-petrogenic hydrocarbons, the effects of environmental processes such as weathering, and the application and limitation of various analytical techniques.

This guidance relates to environmental contamination in the subsurface (soil and groundwater media only); it does not extend to inland waters or to the marine environment. The scope of the document covers petroleum hydrocarbons comprising crude oil and its refined products, and does not include chlorinated hydrocarbons or any other contaminant groups. Biofuels are not considered, other than when blended with petroleum products.

The primary audience is anticipated to be experienced consultants involved in the investigation and remediation of petroleum hydrocarbon contamination. However, the guidance document is also expected to be of use to regulators, site owners, site leaseholders, site operators, and the insurance industry.
