Geomorfología post holocénica y riesgo ambiental: el vertedero de resíduos sólidos urbanos de Jangurussu, Fortaleza, Ceará, Brasil

Abstract

Post Holocene geomorphology and environmental risk: the solid waste landfill of Jangurussu, Fortaleza, Ceará State, Brazil. In countries like Brazil, social and economic inequality leads to most of the population is more tolerant in front of existing serious environmental problems, and makes much of the public is subject to live near landfills municipal solid waste. Built rapidly in urban modeling, creating a new morphology, an aggressive landscape and tangled in a series of many other problems very difficult to solve. The decommissioning plans Jangurussu Weir (Fortaleza, Ceará), representing a clumsy makeup without any environmental functionality and security, becoming eminent potential danger to more than 4,800 people, considering only their immediate environment. No environmental monitoring systems for air, ground and surface water, or for coverage or for their necessary geotechnical stability. The slopes have declined over time depending on the gas transformation of organic waste mass, but today often reach 380. In 1998/99 they reached the 450, in both cases in the northern part of the landfill. The monitoring program quality and necessary to ensure the environmental integrity of the landfill post-closure maintenance, so as to ensure public health, the control and the effective operation of this presumptuous "waste management unit" during the long time required simply do not exist. In 2015 is estimated at 16,608 persons/4,152 rooms (maybe more!), live from the cliffs of the landfill (their quintals), considering the distance of only 50 (or less) meters in the immediate environment, considering only in the north of the landfill.
