Abstract	Managed artificial recharge (MAR) is a well-established practice for augmentation of depleted groundwater resources or for environmental benefit. At the St-André MAR site in the Belgian dune area, groundwater resources are optimised through re-use of highly treated wastewater by means of infiltration ponds. The very high quality of the infiltration water sets this system apart from other MAR systems. The low total dissolved solid (TDS) content in the infiltration water (less than 50 mg/L) compared to the dune aquifer (500 mg/L) triggers a number of reactions, increasing the TDS through soil-aquifer passage. Multi-component reactive transport modelling was applied to analyse the geochemical processes that occur. Carbonate dissolution is the main process increasing the TDS of the infiltration water. Oxic aquifer conditions prevail between the infiltration ponds and the extraction wells. This is driven by the high flow velocities, leaving no time to consume O$_{2}$ between the ponds and extraction wells. Cation exchange is important when infiltration water is replaced by native dune water or when significant changes in infiltration-water quality occur. The seasonal variation of O$_{2}$ and temperature in the infiltration water are the main drivers for seasonal changes in the concentration of all major ions.La gestion de la recharge artificielle (GRA) des aquifères est une pratique bien établie pour réduire l’épuisement des ressources en eaux souterraines ou pour obtenir un bénéfice environnemental. Sur le site de GRA des dunes de St-André en Belgique, la gestion des ressources en eaux souterraines est optimisée via la réutilisation d’eaux usées hautement traitées au travers de bassins d’infiltration. Du fait de la très haute qualité de l’eau infiltrée, ce système occupe une place importante au sein des autres dispositifs de GRA. La faible teneur totale en particules dissoutes (TDS) dans l’eau infiltrée (moins de 50 mg/L) par rapport à celle de l’aquifère au sein de la dune (500 mg/L) déclenche un certain nombre de réactions, augmentant la TDS lors du passage sol-aquifère. Un modèle de transport réactif multi-composants a été appliqué afin d’analyser les processus géochimiques qui prennent place. La dissolution des carbonates est le processus principal qui a pour conséquence une augmentation de la TDS de l’eau d’infiltration. Des conditions de présence d’oxygène dans l’aquifère existent entre les bassins d’infiltration et les forages de pompage. Ce phénomène est dû à la très haute vitesse d’infiltration et d’écoulement ne laissant pas suffisant de temps pour la consommation d’O$_{2}$ entre les bassins d’infiltration et les forages de pompage. L’échange cationique est important lorsque l’eau d’infiltration est remplacée par l’eau souterraine présente dans la dune ou lorsque des modifications significatives dans la qualité de l’eau infiltrée se produit. La variation saisonnière de l’O$_{2}$ et de la température dans l’eau d’infiltration sont les principaux moteurs pour les modifications saisonnières en concentration des principaux ions majeurs.La gestión de la recarga artificial (MAR) es una práctica bien establecida para el aumento de los recursos de agua subterránea agotados o para el beneficio ambiental. En el sitio MAR St-André en el área de dura en Bélgica, los recursos de agua subterránea son optimizados a través del reuso de aguas residuales altamente tratadas por medio de lagunas de infiltración. La muy alta calidad del agua de infiltración coloca este sistema aparte de los sistemas MAR. El contenido bajo de sólidos totales disueltos (TDS) en el agua de infiltración (menos de 50 mg/L) comparado al acuífero de la duna (500 mg/L) dispara un número de reacciones, incrementando los TDS a través del pasaje suelo - acuífero. El modelado de transporte reactivo multi componente se aplicó para analizar los procesos geoquímicos que ocurren. La disolución de carbonato es el proceso principal que incrementa los TDS del agua de infiltración. Las condiciones óxicas del acuífero prevalecen entre las lagunas de infiltración y los pozos de extracción. Esto está forzado por las altas velocidades de flujo, no dejando tiempo el consumo del O$_{2}$ entre las lagunas y los pozos de extracción. El intercambio de cationes es importante cuando el agua de infiltración está reemplazada por el agua de duna nativa o cuando ocurren cambios significativos en la calidad del agua de infiltración. La variación estacional del O$_{2}$ y la temperatura en el agua de infiltración son los principales forzantes para los cambios estacionales en la concentración de todos los iones mayoritarios.人工补给管理(MAR)是一种增加枯竭的地下水资源、提高环境效益行之有效的方法。在比利时沙丘区St-André MAR 场地, 通过渗透池回用深度处理污水是优化地下水资源的最佳方法。这个系统和其他MAR系统比, 渗透水具有非常高的质量。与沙丘含水层中总溶解固体(TDS)相比 (500 mg/L), 渗透水中的低TDS (小于50 mg/L) 含量引起一系列反应, 并致土壤和含水层段中TDS 增加。多组分反应运移模型被用于分析存在的地球化学过程。碳酸盐溶解是伴随渗透水TDS 增加的主要过程。在渗透池和提取井之间以氧化的含水层条件为主。在高流速的驱动下, 在渗透池和提取井之间没有时间消耗氧气。当渗透水被当地的山丘水替换或者当渗透水水质发生重大变化时, 阳离子交换是重要的过程。渗透水中氧气和温度的季节性变化是所有主要离子浓度季节性改变的主要驱动力。A recarga artificial controlada (MAR) é uma técnica já bem implementada para aumentar os recursos hídricos de água subterrânea depauperados ou para benefício ambiental. No local de MAR de St-André, numa área dunar belga, os recursos hídricos subterrâneos são otimizados através da reutilização de água residual altamente tratada através de lagoas de infiltração. A elevadíssima qualidade da água de infiltração coloca este sistema a um nível aparte em relação a outros sistemas de MAR. O conteúdo de sólidos dissolvidos totais (TDS) na água de infiltração (menos de 50 mg/L), quando comparada com a água do aquífero dunar (500 mg/L), desencadeia uma série de reações, incrementando os TDS através da passagem pelo solo e aquífero. A fim de analisar os processos geoquímicos que ocorrem, foi aplicada uma modelação de transporte reativo multicompetentes. A dissolução de carbonatos é o processo principal para o incremento dos TDS na água de infiltração. No aquífero prevalecem condições óxicas entre as lagoas de infiltração e os poços de extração, o que é motivado pelas elevadas velocidades de fluxo entre as lagoas e as captações em extração, que não deixam tempo para o consumo de O$_{2}$. A troca catiónica é importante quando a água de infiltração é substituída por água dunar nativa ou quando se registam alterações significativas na qualidade da água de infiltração. A variação sazonal de O$_{2}$ e da temperatura na água de infiltração são os controladores principais para as alterações sazonais de todos os iões principais.
