Gestão de resíduos sólidos e efluentes domésticos nos municípios da região do carste Lagoa Santa/MG

Abstract

Active karst landscapes are known for their environmental fragility in the face of human pressures. The “Lagoa Santa” karst, located in the northern vector of the Belo Horizonte Metropolitan Region, is characterized by its intrinsic vulnerability, as well as by the intensification of human activities caused by urban expansion. In this context, this study aims to evaluate the management of solid waste and domestic effluents in the following municipalities: Lagoa Santa, Vespasiano, São José da Lapa, Confins, Pedro Leopoldo, Matozinhos, Funilândia and Prudente de Morais. To achieve the proposed objective, the following methodological steps were chosen: (i) analysis of technical documents on Sewage Treatment Plants (STPs) and landfills; (ii) obtaining information from environmental managers and COPASA employees; (iii) technical visits to STPs and landfills; and (iv) spatialization and evaluation of pollution sources (solid waste and domestic effluents) in the municipalities and in the hydrographic network of the study area. In general, there was progress in the management of domestic solid waste in the municipalities under analysis. However, the adherence of households to ETEs is still a worrying factor for the conservation of the region's groundwater resources.
