RESUMO

A case study is presented on waste management practices implemented after a residual fuel oil spill from a steam-generating boiler in an industrial area, and on the technical feasibility of monitored natural attenuation as a treatment option for a recently contaminated tropical soil. One day after contamination, surface soil total petroleum hydrocarbons and phenanthrene concentrations varied from 3.1 to 7.9 g kg(-1) and 149 to 287 µg kg(-1), respectively. Petroleum hydrocarbon concentrations decayed along the monitored time and after 90 days of processes the soil was considered rehabilitated for future industrial use.
