Avaliação dos impactos ambientais causados pela poluição no Rio Poti, perímetro urbano de Teresina – PI

Abstract

The present work is characterized as a bibliographic study that discusses the environmental impacts caused by the pollution of the Poti River, as well as the release of effluents without proper treatment. The main objective was to revisit the literature on the environmental impacts caused by pollution released on the Poti River in the urban perimeter of Teresina - PI, in the East-North region. In addition to evaluating the consequences of those damages caused by the urban drainage system, which comprises surface runoff through gutters, storm drains and galleries, which will flow into the river, compromising its natural course. The methodology used in carrying out the present study was bibliographic research, through which a survey of the literature in books, magazines, newspaper articles and periodicals, as well as in works published in events was carried out. To discuss the data, studies that focused on the analysis of the waters of the Poti River, in monitoring areas, were analyzed. The results found show the inefficiency of the rainwater drainage system and human consumption, and its consequences for the aquatic life of the Poti River, as well as for the entire population of Teresina. Finally, this study highlights Geoprocessing as a tool to control environmental impacts caused by the pollution of the Poti River and as an effective method of monitoring water quality.
