Identificación y selección de tratamientos potenciales para aguas de escorrentía urbana en las cuencas de la hoya de Loja

Abstract

Abstract:Urbanization is a predominant demographic trend generates considerable environmental impacts at local, regional and global scale. In watersheds, urbanization transforms natural landscapes into impervious surfaces and built-up areas, structures that reduce soil infiltration capacity, alter the hydrological cycle and generate pollution problems due to runoff water. The pollutants present runoff water are mostly heavy metals, suspended solids, organic matter, organic micropollutants, nutrients and pathogenic organisms, which reduce the abundance, biological diversity and diversity of aquatic organisms and alter the chemical properties, physical and biological bodies of water. It is a method that can be used to identify the treatment. Thirteen treatments were used for the treatment of urban runoff waters in the basins of the Hoya de Loja, these treatments were classified into three categories: measures of control of rainwater. Low impact development and better management practices. The application of these measures can reduce the levels of flow and the loads of pollutants present in the urban city of Loja and other similar.
