Corrective Action & Remedy Project at the Commonwealth Oil Refining Company (CORCO)

Abstract

The focus of this environmental engineering senior design project is to determine the contaminants of concern in all of the Commonwealth Oil and Refining Company (CORCO) facility and afterwards determine which technology could be implemented to remedy the soil and groundwater. A risk analysis was performed to determine the dose, the hazard risk and cancer risk for each contaminant. Since the CORCO was a petroleum refining company, the majority of the contaminants of concern are petroleum hydrocarbons, volatile organic compounds and some heavy metals. After the contaminants were determined two remedy technologies were selected; Soil Vapor Extraction for the soil and Pump and Treat for groundwater. Additionally as part of the project, a monitoring plan was developed for one of CORCO’s area, the Caribe Isopropane Corporation Tanks. This was developed, to determine the levels of contaminants, since there is no current monitoring in the area. As a conclusion to this project, the levels of contamination at CORCO aren’t of risk; therefore future passive projects could be developed in the area, as a photovoltaic farm.
