Determinación de la calidad de agua de los ríos Santa Ana y Pajonal en la población de Entre Ríos

Abstract

For this investigation, the population of Entre Rios in southern Bolivia was used as the study area. In recent years, this region has experienced a population growth that has brought with it negative impacts on its water resources. The Santa Ana and Pajonal rivers run through the urban area of Entre Ríos, being exposed to different sources of pollution generated by it. These waters, which are used for consumption and irrigation, require a constant evaluation of their quality to ensure the well-being of rural communities and the local ecosystem. In this work, five sampling points in the study area were monitored for physical and chemical analysis of the samples. High levels of organic contamination that exceed the national regulations were identified, the source of these being a combination of factors linked to poor wastewater management in the area. Based on the results obtained, strategies are proposed to optimize the current water management, considering the health risks to which the rural communities downstream are exposed due to the lack of an adequate water purification systems.
