Contaminação das águas do lençol freatico por disposição inadequada de resíduos sólidos urbanos e monitoramento por imagens de satélite na bacia do Araripe região do Cariri, CE,Brasil

Abstract

The Solid Urban dump of Juazeiro do Norte is located in the region of Cariri, the southern tip of the state of Ceará, next to the right bank of the river Batalheiras, being part of the hydrographic basin of the river Salgado. The dump of Juazeiro- do Norte is still producing slurry, which freeiy fiows through its northern and eastern siopes, directiy into the existing surface water bodies, but also seeping into groundwater and emerging as base flow of the river Batalheiras. The type of soil in the landfill facilitate the groundwater contamination pfocess as it has a very high perfneability; it facilitates the flow of Iiquid percolates through the soil and subsoil. Since these waters could present high risk of contamination, therefore causing damage to the population using this resource. The objective of this research is to show the importance of the Araripe Basin and environmental consequ-ences- of poor solid waste disposal, making an environmental diagnosis of the landfill through satellite high resolution images of the county of Juazeiro do Norte, with observation/evaluation of the water contamination levei from the groundwater. Taking into account what has been analyzed, it is clear that groundwater and surface water in the area studied in the Araripe Basin, are being contaminated by improper disposal of solid waste deposited in the landfill, generating fluids (slurry) that is in contact with the groundwater and surface water in its surroundings.
