Análisis de la calidad de agua en la cuenca del río Guayllabamba y la zona de influencia EPMAPS - FONAG: water quality analysis taking into account major ions, minor ions and trace elements of the sources and slopes from the Western Cordillera.

Abstract

This research seeks to know the interactions between geological processes or anthropogenic activities and chemical processes of natural acquisition that aquifers in the Guayllabamba river basin can have. One of our questions is how these changes could be decisive in the quality of water in the basin and the EPMAPS - FONAG area of influence. Data of major, minor ions and trace elements from the wells and springs within the Guayllabamba river basin and the FONAG area of influence were used. This information was separated in two groups. The first groups those which come from the Western Cordillera and the other group, those coming from the Eastern Cordillera. Then ionic balances were caculated. Consequently, a statistical analysis using Piper and Stiff diagrams were perfomed. This result lead to an understanding of the basic mineralization processes. Finally, the classification and type of water were obtained. With such results, it was also possible to know the effects on human health of some elements of this chemical acquisition. In addition, based on this information, it is expected that the stakeholders can generate prevention measures, alerts or decision-making instruments within the study area.
