Avaliação dos impactos ambientais adversos em um “lixão” no município de Santa Cruz - PB.

Abstract

The final disposal of solid waste in dumps is a very old and still used in many Brazilian municipalities, being an inadequate practice that causes several environmental impacts to the environment. The objective of this work was to evaluate the adverse environmental impacts generated in a "dump" in the municipality of Santa Cruz-PB. The methodology adopted was based on bibliographic research in technical and scientific studies, photographic records, field visits, satellite images, and the use of environmental impact assessment methodologies: ad hoc methods, check lists and interaction matrix. A simplified environmental diagnosis was developed to describe the area conditions. Subsequently, the identification, evaluation and classification of adverse environmental impacts were made, and control measures and environmental plans and / or programs were proposed. In all, 73 adverse environmental impacts were identified and the largest number was identified in the implementation phase, followed by the operation phase, of which 51 presented a level of significance. For these impacts considered to be very significant and significant, mitigating and compensatory measures were proposed. In order to evaluate the efficiency of these measures, environmental plans and programs were suggested, highlighting the environmental education program for the municipality's population and the soil quality monitoring program.
