Analysis of Soil Vapor Extraction Expenses to Estimate Bioventing Expenses
AIR FORCE INST OF TECH WRIGHT-PATTERSON AFB OH
Pagination or Media Count:
An in-depth analysis of the expenses incurred with five soil venting petroleum remediation projects was accomplished. The data was obtained from receipts provided by a major United States petroleum refiner and distributor. Cost categories were designed that incorporated all costs and provided a method to analyze the data. The five cost categories used were permits, equipment, management, utilities, and analysis. Further analysis showed trends and described the behavior of the costs related to remediation events. The relative percentile for each cost category was found to be consistent among the projects. Many costs were also found to be very linear through out the life of the project from discovery to final cleanup. These linear costs for each cost category were also found to have similar slopes when comparing different projects.
