To determine differences within the three types of hydrocarbon contamination, analysis of the statistical variance test within JMP™ statistical software was utilized. Then, simple linear-regression analysis tests were used to understand the relationship between the soils’ TPH and parameter concentrations. This was followed by a forward stepwise regression analysis test to determine the optimal model that combined multiple factors of soil parameters with the TPH concentration. Lastly, the vegetation-cover percentage for each TPH-contaminated category was compared with the three TPH categories and the soil parameters to determine the impact of soil heavy-metal and nutrient concentrations on plant growth.
