ABSTRACT

Gasoline spills and leakages from Underground Storage Tank (UST) leaks are common occurrences in the United States. They are typically referred to as Light Non Aqueous Liquids (LNAPLs). There are historical releases, leaks from several sources in the same vicinity, and recent releases. This presentation will provide the tools necessary to measure the contaminants released into the ground which in many cases end up in the groundwater aquifers.
This presentation will outline the analysis required to determine the composition of the product released and approximate age of the product by analyzing the product for indicator parameters such as additives. Typically, Whole Oil Analysis is performed to identify the products. Once the product is identified more sophisticated analysis such as PIANO analysis and additives identification is performed in the laboratory. Diagnostic ratios will be discussed as to the various pathways the weathering of the product proceeds in the environment. All necessary tools required for data assessment will be outlined.
