Monitoramento ambiental da qualidade da água do Rio Itacarambi - MG

Abstract

Water availability is becoming limited due to high consumption and increasing pollution, affecting its quality and socio-economic development of a region. The present study aims at evaluate water quality in the Itacarambi river, in the São Francisco River basin, located in the north of Minas Gerais, considering the importance of that river to the local population. Thus, we adopted the parameters defined in CONAMA Resolution nº 357/2005 and COPAM/CERH Joint Normative Deliberation nº 01/2008. Water samples were collected in August and December 2011, in six georeferenced points along the river. The results obtained for the parameters turbidity, apparent color, dissolved oxygen (DO), biochemical oxygen demand (BOD) and total phosphorus values were critical that showed environmental degradation. This work allowed the identification of environmental impact points on the body of water, contributing to the management of water resources of the watershed and protection of public health.
