Análise de risco do potencial de contaminação sobre as áreas das bacias Rio Alegria e Ouro Verde no município de Medianeira - PR

Abstract

This study is an analysis of the Alegria river basin and the Ouro Verde river basin. The Rio Alegria is one of the main sources of capture in the municipality of Medianeira, having a large area affected by various activities such as urban growth, agriculture, industrial activities, which can cause degradation and contamination of the area, also impairing the quality and quantity of water. water available during the course of the river. The Ouro Verde River is seen as a possible alternative for a new source. Thematic maps were prepared with the aid of the geoprocessing tool, through the images provided by TOPODATA and by INPE, which allowed the construction of maps such as land use and occupation, slope and hypsometry; from this, it was possible to analyze the results indicating the potential for contamination The study provided mitigating measures for the areas of the Rio Alegria basin that are affected, with a smaller amount of app areas, great interference from the ETE and companies upstream of the capture and most of the use and occupation destined for agriculture, in order to guarantee that the basin is no longer devastated or contaminated, in addition to analyzing the possible adverse effects that could be avoided in the new source of the Ouro Verde basin.
