Análisis comparativo de diferentes índices para evaluar la calidad de agua del río Puyango en la zona minera de Portovelo

Abstract

Abstract: This research work arises from the need to know the quality of water and to monitor the water bodies that exist in Ecuador, which serve thousands of people to meet their basic or productive needs. The problem lies in the identification of the contamination of domestic, agricultural and industrial anthropogenic origin of the Puyango River, which has affected Ecuadorians and Peruvians since the 60's. One of the main objectives is to know the quality of the water in the Puyango River. One of the main objectives is to know the river's water quality by means of an index that allows it to be compared with others. The methodology was based on the collection of historical information, the selection of parameters, the design of the monitoring network, the water and sediment sampling campaign, laboratory tests, statistical analysis, the definition and calculation of AQIs according to the requirements of the riverbed and their comparison, and the design of a remediation plan for possible decisions. The fundamental contribution is aimed at alerting the authorities and those responsible for the state of the river over the last 60 years, so that the National Government defines and implements action plans to control the sources of contamination indicated, in order to minimize the negative effects suffered by the population that uses its waters.
