La cuenca del arroyo Las Piedras se encuentra en el sur del conurbano bonaerense, sufriendo hacedécadas los impactos del crecimiento urbano en un contexto de escasa planificación territorial. Esto se evidencia en inundaciones recurrentes, contaminación hídrica y residuos urbanos en agua y riberas. El objetivo de este trabajo es evaluar el cambio temporal en el uso del suelo, valorar la calidad de agua y la contaminación orgánica en la cuenca del arroyo Las Piedras. El cambio en el uso del suelo fue analizado mediante el uso de un software de análisis geográfico de imágenes satelitales Landsat 8 de los años 2013 y 2020. Asimismo, se evaluaron distintos parámetros fisicoquímicos y microbiológicos en cuatro puntos del arroyo, calculándose los índices de calidad de agua (ICA) y de contaminación orgánica (ICOMO). Se observó un incremento del área urbana sobre áreas verdes, un ICA de medio a regular y un ICOMO de medio a muy alto.
The Las Piedras stream basin is located in the south of the Buenos Aires suburbs, detecting for decades the impacts of urban growth in a context of poor territorial planning. This is evidenced by recurring floods, water contamination and urban waste in water and riverbanks. The objective of this work is to evaluate the temporary change in land use, evaluate water quality and organic contamination in the Las Piedras stream basin. The change in land use was analyzed by using a geographic analysis software of Landsat 8 satellite images from the years 2013 and 2020. Likewise, several physicochemical and microbiological parameters were evaluated at four points of the stream, calculating water quality (ICA) and organic contamination (ICOMO) indices. An increase in the urban area over green areas, an ICA from medium to regular and a ICOMO from medium to very high were observed.
