Impactos na qualidade da água do rio Gurgueia pelo uso e ocupação do solo no município de São Gonçalo do Gurgueia - Piauí

Abstract

Since the creation of the first cities, when the nomads began to set up fixed camps in a certain region, areas near the water bodies were chosen because of the ease of obtaining water for consumption. The areas that are located in the surroundings of the Brazilian rivers are called Permanent Preservation Areas (APP) and considered public, hence the ease of occupation by the low-income population that occupies and appropriates these areas clandestinely. This study aimed to evaluate the use and occupation of the soil in the areas of permanent preservation of the Rio Gurgueia in the urban perimeter of the municipality of São Gonçalo do Gurgueia, as well as to perform the analysis of the quality of the waters of the Gurgueia River, in the region of influence of the County. After evaluations and analyzes it can be observed that more than 50% of the areas of PPAs are with irregular occupations which may have generated impacts on 9the water quality of the water body that is below the indicated.
