Geoprocessing used in the selection of areas for deployment of landfill in the municipality of Conceição das Alagoas (MG), Brazil

ABSTRACT Given the large amount of solid waste disposed in open dumps, contaminating the soil, the water and the air, there was a need to improve and adjust the final disposal of such waste. The main objective was to identify potential areas for the construction of a municipal landfill, in order to reduce the environmental impacts generated by incorrect disposal of this waste in the municipality of Conceição das Alagoas, Minas Gerais, Brazil. The methodology used in the survey of potential areas was based on a digital mapping using geographic information system techniques. In the first step, the surveys of restrictive and potential zones in the municipality of Conceição das Alagoas were conducted for the landfill implementation. In the second step, we evaluated all areas inserted in the potential zone, in which six areas were determined as suitable for the landfill deployment according to restriction criteria.
