On-site Chemical Oxidation/Destruction of Petroleum Contaminated Soils

Chemical oxidation/destruction of petroleum contaminated soils is a safe expedient way of destroying TPH materials.  The process simply converts the petroleum into inert by products such as carbon dioxide and water.

The process progresses fairly rapidly with results ranging up to 90-99% destruction depending on the carbon length of the TPH. The process is accomplished ex-situ where blending and through mixing will occur. The approach optimizes the economical use of reagents to get the greatest economy and efficiency.

In earlier systems the materials were applied in-situ and were subject to hot spot retardation and preferential pathway channeling. Both of these aspects a fully avoided by ex-situ processing.

Recently the EPA has clarified that processing in the area of contamination does not trigger the “generated waste” issue that so often encumbers cleanup of contaminates sites. Chemical oxidation as specified above falls into this scenario.
