Abstract—In this study, a crude-oil contaminated stockpile is analyzed to understand the health risks and technical approach in its remediation. The stockpile has an approximate area of 13 hectares, with an approximate volume of 1.300.000 m3. Relaxed government regulations regarding environmental protection up in 2014 have made stockpiling crude-oil contaminated soils commonplace in Indonesia's oil and gas fields. The stockpile has a flat-shaped landscape, sloping at approximately 10 to 15 degrees, with a varied elevation ranging from 29 meters to 31 meters, peaking at 31.5 meters. This study's objective was to correctly identify the best curative approach to remediate the location to adhere to the Indonesian Government standards and best practices. A landfill "cap" aims to treat the hazardous waste stockpile similar to a typical landfill, though with the absence of the base layer below the stockpile.
Index Terms—Landfill capping design, hazardous waste landfill, crude oil contaminated soils, risk-based screening levels.
