Oil spills and their impacts in a long term period have been poorly investigated, especially when it comes to onshore oil spills. One of the biggest onshore oil spills took place in Michigan, Kalamazoo on July 26, 2010. Nearly 4 million liters of Diluted Bitumen (Dilbit) were spilled reaching the Kalamazoo River. Extensive efforts were made in order to clean and recover the affected area, as well as concentration and composition surveys of the oiled soil. The main purpose of this article is quantify and qualify the hydrocarbon content in the Kalamazoo River riparian sediments five years after the oil spill. Analytical techniques, such as, Total Petroleum Hydrocarbon (TPH) and GC-MS were used to evaluate the chemical composition changes in 12 soil samples. The results show that the hydrocarbons content went by different kind of degradation mecanism depending on the type of the soil. There was reduction of 12,1% through 5 years. However, it also shows significant concentrations of pretroleum basis componentes, for example, chrysene and pyrnere. These hydrocarbons are Strong indication of oil degradation and cancerous content A correaltion between hydrocarbons were found in the oiled samples, which did not agree with sample 1 (not oiled). It indicates that the contamination comes from one source, the Dilbit spilled by Enbridge Partners.
