Controle de poluição ambiental na área de implantação do reservatório do projeto Jequitaí

Abstract

The Jequitai Project is located in the north of Minas Gerais and composes the revitalisation program for the basin of the Sao Francisco River. Its deployment aims to increase and flow rate control of one of its major tributaries, the Jequitaí River. The objective of this study was to analyze the parameters of water quality (dissolved oxygen, biochemical oxygen demand, thermotolerant coliforms, suspended solids, turbidity, dissolved organic phosphorus, total phosphorus, nitrite, nitrate and total Kjeldahl nitrogen) before the construction of the barrage One of the Project Jequitai, obtained through the Lake Monitoring Program and the quality of the water, prepared by CODEVASF. During the monitoring realized between the years of 2014 and 2015, in four sampling stations of lotic environments, data relating to organic matter, pathogenic microorganisms, solids and nutrients were analyzed by the author. The monitoring was important to suggest the deployment of the effluent treatment system of low cost and easy to management in rural properties on the edge of the future reservoir, so that the improvement of environmental quality enabling an increase in the useful life of the Project Jequitai reservoir, considering during the operation of the reservoir there will be an increase in the consumption of water for irrigation, the quantity of properties in the effuse and tourism in the region.
