Risco de contaminação de mananciais superficiais e do sistema aquífero serra geral por aterros na região metropolitana de Londrina - PR

Abstract

The populations of urban centers have steady growth, largely because of developments of actions in favor of health and well being of human beings, so, there was the exaggerated increase in consumption, generating more and more discarded waste. With that, increasingly, there is a need to create more areas to have ultimate way municipal solid waste (MSW), however, these sites should follow minimum requirements for structure and operation to the provision of this service. Exposing this, the present work, performed the analysis of the final disposal sites of MSW in the metropolitan region of Londrina (RML) and their distance to surface water bodies and supply wells, for conducting this study, we used the Information System geographic (GIS) in order to manipulate, visualize and evaluate the data using as parameter the Law 12.305 / 2010 (National Policy on Solid Waste) and the ABNT standard NBR 13867: 1997. Also, for a more careful examination of the possible degradation aquifers, an aquifer contamination risk map for landfills belonging to RML was produced by using an index called GOD and IQR (Quality Index Landfill), criando- A new risk assessment method to contamination of groundwater, called Riqa. This study showed that only 25% of the municipalities belonging to RML has correctly their RSU in turn the other 75% have garbage dumps for allocation of these wastes, a scenario of possible deterioration of the environment. In addition, more than 31% and almost 19% of these landfills cities are allocated within 200 meters of surface water sources and supply wells respectively and two of these municipalities presented high risk of aquifer.
