This open access book synthesizes important advances in the assessment and management of soil
and groundwater systems contaminated with petroleum hydrocarbons especially in the form of
light non-aqueous phase liquids (LNAPLs). LNAPL characterization and remediation is challenging
due to the multi-phase multi-component nature of the problem and the various physical
chemical and biological processes involved in a dynamic and heterogeneous hydrogeological
setting. This book focuses on the current state of practice of LNAPL characterization and
remediation and seeks to provide information and a framework that would allow some of these
complexities to be better addressed by contaminated land practitioners researchers and
regulators.
