It is, clearly, a Government responsibility to enact laws and promulgate regulations for control of industrial pollution. The main techniques for soil industrial wastes disposal, namely, landfarming and landfilling, profit from the extensive knowledge acquired, in past decades, in the field of water and air pollution control and must be analysed within a comprehensive system for hazardous waste management, with its legal and administrative aspects. This paper presents some general principles of a Hazardous Waste Management System, which are broadly applicable, regardless differences between States or Countries. Finally, it discusses the specific case of Hazardous Wastes Management in the State of Bahia, Brazil and makes some suggestions for its improvement.
