Avaliação da contaminação do solo pela disposição inadequada de resíduos sólidos em Romaria-MG

Abstract

This research seeks to demonstrate in a simplified manner, the risks of inappropriate use areas and techniques for the disposal of solid waste in small urban centers. In these areas, waste is dumped on the ground without any measure of protection to the environment or public health, which affects soil quality and ecological balance. Another aspect is of utmost importance in these areas because of proximity to watercourses, which might have an adverse effect on quality. Thus, researched the city of Romaria-MG as an example of the problems described. The municipality is located in the Triangulo Mineiro region with land area of 401,965 km² and an estimated population of 3.636 inhabitants. The \"dump\" open pit is located 1.5 km from the urban area with total area of 10,523.51 m², being considered for this study, only the area with the greatest ease of operation with 9.820 m². The \"dump\" is far from 203.65 meters from the main source of water in the city of Estrela do Sul, Minas Gerais, River Bagagem. In the study area is possible to diagnose various types of waste, including organics, recyclables, the health service, the construction etc. The parameters analyzed allowed the characterization of the study area, as well as the investigation of soil contamination by heavy metals. Thus, we tried to steer some measure of recovery of the area through modern techniques of environmental geotechnical.
