Avaliação de áreas para instalação de aterro sanitário no município de Barreiras, Bahia

The increasing amount of waste generated by urban areas is becoming worrying, especially as regards the conservation of the environment and public health of the population, which requires some care needed for the construction of sanitary landfills. For installation of this enterprise are needed technical studies, environmental and socioeconomic used to evaluate a number of criteria for the selection of suitable areas deploying the sanitary landfill in order to minimize impacts. This study aims to demonstrate some weaknesses in the sanitary landfill Barriers city, Bahia, Brazil. The vicinity to the highway (BR-242) of general circulation was the main irregularity found in the current sanitary landfill, which may facilitate disease transmission through locomotors vehicles that travel near the area. We performed a proposed new sanitary landfill, based on the ratio of distances between some important variables in this process. The identification of this new proposal, it was observed that there is no restriction regarding the proximity to roads, slope flat, away from rivers, the urban and protected areas. The Geographic Information System demonstrated to be a practical, economical and reliable, which can contribute to the selection of the areas appropriate the installation to sanitary landfill because it integrates a number of physical, biotic and social analysis in computational media, which minimize the environmental impacts caused by the project and avoid unnecessary costs.Pages: 842-84
