Levantamento da qualidade ambiental do córrego capim puba no município de Goiânia - GO

Abstract

Water is an essential natural resource for the maintenance and life of humans, however, anthropogenic actions have disrupted aquatic ecosystems and threatened freshwater sources. The objective of this work was to verify the environmental quality of the Capim Puba stream, located in the city of Goiânia, state of Goiás, during the rainy season of 2016. The samples were collected in three sampling points distributed along the course of the creek: 01 located at the source, point 02 at the site of greater anthropic occupation of the stream banks and point 03 at the confluence with the Botafogo Stream. Environmental quality was investigated through the identification of domestic and industrial effluent release points, level of silting, presence of erosion, debris, flora, solid residues and liquid residues, as well as analysis of physical and chemical variables of the aquatic environment. It was possible to notice greater environmental degradation in point 02 due to anthropic occupation. In addition, the adverse impacts were less intense when compared to previous years, revealing a capacity of the autodepuration stream. © 2020 Centro Universitario de Anapolis. All rights reserved
