| dc.description.abstract | The poor management of the leachates generated at the solid waste final disposal site in El Carrasco, Bucaramanga, Colombia, has been worrying environmental authorities for some years because its risk of contamination for the soil and the water in the disposal and closed areas.Objective.To establish the migration route for the leachates generated in El Carrasco landfill, in Bucaramanga, and in the direct and indirect areas of influence of the disposal site, by means of the analysis and the interpretation of the data obtained by the use of geoelectric units.Materials and methods.IT tools were used, including geographic information systems, the Modelmouse software, 180 meters deep vertical electrical soundings with a mesh modeling model comprised of 45 lines and 35 columns -10x10m- and six layers that met the units identified in the direct disposal area by means of a stratigraphic profile.Results.The results of the modeling developed within the MODFLOW environment show an East-West flow in most of the layers. The same happens with the flow established by the load coming from the Santander mountain range, where the resistivity rates are very low. Conclusion.Low resistivity zones associated, generated by the leachates, and fully saturated zones that were poorly managed in the disposal site, were identified for the area studied, by means of methodologies that combine geophysics, geology, hydrogeology and geochemistry | es_ES |
| dc.description.resumen | El deficiente manejo de los lixiviados generados en el sitio de disposición final de residuos sólidos de El Carrasco de Bucaramanga (Colombia) despertó, desde hace algunos años, preocupación por parte de las autoridades ambientales, debido al riesgo de contaminación de los recursos suelo y agua, en áreas de disposición y clausuradas. Objetivo. Establecer la ruta de migración de los contaminantes presentes en los lixiviados generados en el relleno El Carrasco de Bucaramanga y en el área de influencia directa e indirecta del sitio de disposición, a través del análisis y la interpretación de datos obtenidos con unidades geoeléctricas. Materiales y métodos. Se emplearon herramientas informáticas que incluyen el uso de los sistemas de información geográfica, el programa Modelmouse, métodos de sondeos eléctricos verticales con profundidad de 180 m, en el cual se estableció un modelo de malla conformada por 45 filas y 35 columnas 10x10 m y 6 capas que se encontraban con las unidades identificadas en el área directa de disposición mediante un perfil estratigráfico. Resultados. Los resultados de la modelación desarrolladas en el entorno MODFLOW muestran un flujo en dirección este-oeste en casi todas las capas; asimismo, el flujo establecido por la recarga proveniente del macizo de Santander, donde los niveles de resistividad son muy bajos. Conclusión. Se identificaron para la zona de estudio, a través de metodologías combinadas de geofísica, geología, hidrogeología y geoquímica, zonas con resistividades bajas asociadas, generadas por los lixiviados, y zonas totalmente saturadas que no fueron manejadas de manera adecuada en el sitio de disposición. | |
