Geoenvironmental constraints as limiting factors in the siting of the Greater Aracaju sanitary landfill – Municipality of Nossa Senhora do Socorro, Sergipe (SE)

Abstract

One of the main environmental problems is the production of waste and its disposal in inappropriate places. Thus, the landfill for municipal solid waste are the provision of technical, minimizing environmental impacts. The objective of this study is to complete the characterization of the geoenvironmental constraints within the area of influence of the project Sanitary Landfill, in the Palestinian víllage, municipality of Nossa Senhora do Socorro (SE), in order to identify the degree of importance of the possible impacts arising from the implementation and operation of this venture. The methodological procedure was based on the fundamental theory of General Systems, including analyses sidewalks in the cause-effect relationship. They are for reference levels of approach ecosystemic, according to Monteiro (2000), comprising the steps of information, analysis, integration, synthesis and application. It was done, also, lifting of analog and digital data in public agencies, the fieldwork for recognition of the field of study and collection of information, development of cartograms through digital cartography and other cartographic documents (digital aerial photos and various thematic maps). The area of direct influence of the venture covers geomorphological units Coastal Plateaus and Aluvial Plain. The existence of a level more retained (on the erosional tabular surface) and the surface dissected into hills, crests and tabular interfluves, characterize this unit geomorphological where Red-yellow Argisol Plinthic and non-plinthic texture of sandy clay-average and average is associated to Eutrophic Equivalent Red-Yellow Argisol of medium texture and the clay Vertisolo- Pv18. The characterization of the physiographic aspects allowed the identification of more critical excerpts (from the point of view of erosion) to the engineeríng works which will be implemented in the enterprise.
