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 paper based on the demosite in Westland (The Impact of Integrated Aquifer Storage and Recovery and Brackish Water Reverse Osmosis (ASRRO) on a Coastal Groundwater System) is the first to report on the impact of aquifer storage and recovery and reverse osmosis (ASRRO). This system is technically able to provide a robust freshwater source. This study however analysed the impact on the groundwater system if it would be widely implemented. Therefore, the current situation (brackish water RO) was also evaluated. It was shown that the introduction of the DESSIN solution would have great benefits for the groundwater system, especially close to the groundwater wells ('local scale'). On a regional scale, overall effects on the salinity was limited in all scenarios for 30 years and saltwater intrusion was clearly reduced by ASRRO.
