A special issue on managed aquifer recharge (MAR) of MDPI Water has been released. It is aiming at hydrogeochemical and water quality management aspects, such as the benefits of self-purification during aquifer recharge and storage, including bank filtration, and problems due to undesired water-aquifer interactions and clogging of infiltration and injection systems. From both, the Barcelona and the Westland demosite, a paper was submitted and accepted for publication.

The Barcelona paper (Evaluation of Clogging during Sand-Filtered Surface Water Injection for Aquifer Storage and Recovery (ASR) Pilot Experiment in the Llobregat Delta (Barcelona, Spain)) focuses on the clogging of the aquifer storage and recovery (ASR) wells during injection of sand filtered water, which was simulated under lab conditions. It was shown that although microbiological clogging was observed, the operational capacity of the ASR well will not be heavily impacted. This means that there is clear potential to inject sand filtered water at the site in order to store freshwater for moments when intake of river water is hampered.
