Perbandingan Laju Lindi Landfill Kelas I dan II untuk Limbah NORM dari Industri Minyak dan Gas Bumi Menggunakan Model Hydrologic Evaluation of Landfill Performance (HELP)

In the process of oil and gas production, it can produce large amounts of Naturally Occurring Radioactive Materials (NORM) with increased radioactivity as by-products. NORM disposal methods currently used in the oil & gas industry are landfills, land-spreading, surface burial, underground injection, off-shore discharge. The biggest threat to groundwater caused by landfills is leachate. This study is a comparison of the leachate rates of Class I and Class II Landfill results using the Hydrologic Evaluation of Landfill Performance (HELP) modeling software developed by the United States Environmental Protection Agency (US EPA). For the operational phase, there were significant differences in leachate rate from the base layer between Class I and Class II landfills. For the phase after closure of waste, Class I and Class II landfills have the same performance in terms of holding back the rate of leachate.
