Qualidade das Águas Superficiais e o Uso da Terra: Estudo de Caso Pontual em Bacia Hidrográfica do Oeste do Paraná

Abstract

The overall objective of this work was to seek an association between the parameters of water quality and the identification of possible pollutants in a watershed in the southwest of the State of Parana. As much information as possible about the studied area was spotted, establishing relationships between the components of farmland and urban land use and the outcome of the physical-chemical and biological analyses carried out in two sampling spots from Santa Rosa River. Orthoimages taken by SPOT 5 satellite and a letter from the 'Paranacidade' Autonomous Service were used. The public domain SPRING 5.1.6 application was used. When comparing the water quality with the Resolution 357 (2005) by CONAMA, for class II rivers, high levels of oil, grease, boron, dissolved iron, total coliforms and fecal coliforms were found. Thus, possible relationships between the rates that were over the legal limit and the possible pollutants were investigated.
