Abstract
Between July 2001 and February 2002, a waste, classified as inert, was transported from the Portuguese Iron and Steel Company facilities located in Maia, where it had been stored from 1976 to 2001, and dumped on the spoils of an old coal mine in Sao Pedro da Cova, close to Oporto. In 2010, LNEC- Laboratorio Nacional de Engenharia Civil (National Laboratory for Civil Engineering) studied the waste disposal to reassess its hazardousness. The results obtained showed that the waste was hazardous and, therefore, its removal to a hazardous waste landfill was necessary given the risk to the public health and the environment. In this paper the actions developed during the phases of site investigation of the waste disposal and environmental rehabilitation are presented. These actions include boreholes, waste and subsoil sampling, laboratory tests (physical, chemical and environmental), waste removal, and evaluation of the contamination of the subsoil underlying waste disposal. This characterization showed that the migration of the pollutants from waste to subsoil was not very significant after being in contact for about twelve years.
