Baseline of the outcropping Guarani Aquifer System in Rivera and Tacuarembó, Uruguay: Piezometry and Vulnerability
The piezometric, water table and vulnerability baseline of the outcropping Guaraní Aquifer System (GAS) in the departments of Rivera and Tacuarembó (Uruguay) is presented. The flow network and chemical composition are essential to understanding underground dynamics and identifying recharge and disch...

| description | The piezometric, water table and vulnerability baseline of the outcropping Guaraní Aquifer System (GAS) in the departments of Rivera and Tacuarembó (Uruguay) is presented. The flow network and chemical composition are essential to understanding underground dynamics and identifying recharge and discharge zones, preferential flow directions, and determining hydraulic gradients. It is essential to analyze its evolution in time and space from the baseline, for the management and protection of the resource. Vulnerability was determined by applying the GOD and EKv methods, obtaining similar results, with areas of high and moderate vulnerability in most of the studied area. The risk of groundwater contamination was determined using the method of Foster & Hirata(34), obtaining high risk for potentially polluting loads from lack of sanitation, solid household waste, irregular settlements, and gas stations, in areas of moderate and high vulnerability. Industrial and mining activity and a cemetery represent a moderate risk in most cases. Having maps of vulnerability and risk of groundwater contamination is essential to identify the most vulnerable areas and implement detailed study, control, and protection tools aimed at conserving and mitigating impacts on GAS. |

La red de flujo y la composición química son esenciales para comprender la dinámica subterránea e identificar zonas de recarga y descarga, direcciones de flujo preferenciales y determinar gradientes hidráulicos. Analizar su evolución en el tiempo y en el espacio a partir de la línea de base es esencial para la gestión y la protección del recurso. La vulnerabilidad se determinó aplicando los métodos GOD y EKv, obteniendo resultados similares, con áreas de vulnerabilidad alta y moderada en la mayor parte del área estudiada. El riesgo a la contaminación del agua subterránea se determinó utilizando el método de Foster & Hirata(34), obteniéndose riesgo alto para cargas potencialmente contaminantes provenientes de falta de saneamiento, residuos sólidos domiciliarios, asentamientos irregulares y estaciones de servicio, en zonas de vulnerabilidad moderada y alta. La actividad industrial y minera y el cementerio representan un riesgo moderado en la mayoría de los casos. Disponer de mapas de vulnerabilidad y riesgo de contaminación del agua subterránea es imprescindible para identificar las zonas más vulnerables e implementar herramientas de estudio detallado, control y protección que tiendan a la conservación y la mitigación de impactos en el SAGa.É apresentada a linha de base piezométrica, do lençol freático e de vulnerabilidade do Sistema Aquífero Guarani aflorante (SAGa) nos departamentos de Rivera e Tacuarembó, Uruguai.

A vulnerabilidade foi determinada aplicando-se os métodos GOD e EKv, obtendo-se resultados semelhantes, com áreas de vulnerabilidade alta e moderada na maior parte da área estudada. O risco de contaminação dos lençóis freáticos foi determinado pelo método de Foster & Hirata(34), obtendo-se alto risco para cargas potencialmente poluidoras por falta de saneamento, resíduos sólidos domiciliares, assentamentos irregulares e postos de serviços, em áreas de vulnerabilidade moderada e alta. A atividade industrial e de mineração e o cemitério representam um risco moderado na maioria dos casos. Ter mapas de vulnerabilidade e risco de contaminação de lençóis freáticos é essencial para identificar as áreas mais vulneráveis e implementar estudos detalhados, ferramentas de controle e proteção destinadas a conservar e mitigar impactos no SAGa.Facultad de Agronomía, Universidad de la República - INIACollazo Paula, Universidad de la República, Facultad de Ciencias, Instituto de Ciencias Geológicas, Montevideo, Uruguay https://orcid.org/0000-0003-2053-74812024-04-26T15:11:21Z2024-04-26T15:11:21Z2022Artículoinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersione507application/pdfCollazo, P.
