Environmental issues associated with disposal of processed oil shale tailings and various chemical wastes from the Maoming Petrochemical Company in landfills near Maoming, China, are reviewed. Soil, water, and oil shale tailing samples were analyzed. Soil and groundwater are contaminated by oil shale tailing chemicals to various degrees, depending on the distance from tailings. Soil and groundwater acidification, high levels of heavy metals and sulfate in soil and groundwater, and organic contamination of soil (mainly with PAHs retained in soil) were detected. Remediation requirements for the landfill are discussed.
