Different types of managed aquifer recharge (MAR) schemes are widely distributed and applied on various scales and for various purposes in the European countries, but a systematic categorization and compilation of data has been missing up to now. The European MAR catalogue presented herein contains various key parameters collected from the available literature. The catalogue includes 224 currently active MAR sites found in 23 European countries. Large quantities of drinking water are produced by MAR sites in Hungary, Slovakia, the Netherlands, Germany, Finland, Poland, Switzerland and France. This inventory highlights that, for over a century, MAR has played an important role in the development of European water supply and contributes to drinking-water production substantially. This development has occurred autonomously, with “trial-and-error” within the full range of climatically and hydrogeologically diverse conditions of the European countries. For the future, MAR has the potential to facilitate optimal (re)use and storage of available water resources and to take advantage of the natural purification and low energy requirements during MAR operations. Particularly with respect to the re-use of wastewater treatment-plant effluent and stormwater, which is currently underdeveloped, the use of MAR can support the public acceptance of such water-resource efficient schemes. Particularly for the highly productive and urbanized coastal zones, where the pressure on freshwater supplies increases by growing water demand, salinization and increased agricultural needs for food production (such as along the Mediterranean and North Sea coasts), MAR is expected to be increasingly relied on in Europe. © 2017 The Author(s)

The water and waste water sector is facing tremendous challenges to assure safe, cost-effective and sustainable water supply and sanitation services. DEMEAU promotes the uptake of knowledge, prototypes and practices from previous EU research enabling the water cycle sector to face emerging pollutants and thus securing water and waste water services and public health. The project exploits four groups of promising technologies from previous EU research: Managed Aquifer Recharge (MAR), hybrid ceramic membrane filtration, hybrid advanced oxidation processes, bioassays. Exploitation takes place through action research with universities, research institutions, innovative SMEs, launching water utilities and policy makers. Essential in the DEMEAU approach is the cooperation with water utilities that have committed to act as launching customer for the selected technologies. Existing and improved performance assessment methodologies will be used to benchmark the novel technologies against existing ones. This is to demonstrate the suitability and cost-effectiveness of the demonstrated technologies. Demonstration sites at launching utilities act as transfer points for the technologies and will generate market opportunities for the SMEs involved. To foster a broader impact and market penetration of the technologies, DEMEAU seeks cooperation with relevant policy makers, regulators and standardization bodies on Member State and European level in order to address barriers and promoters for the implementation. A considerable percentage (39%) of the total requested EC contribution is allocated to SMEs.

Only few sulfonamide antibiotics were detected in near-surface groundwater in areas with a high stocking rate in northwestern Germany. Intensive sampling with a high resolution in time and space was applied in order to illuminate the findings. As some pharmaceuticals can be of both human and animal origin, they may enter the environment via application of manure/digestate to arable land or via domestic waste water. In addition to existing monitoring wells, non-permanent wells were sampled to obtain information regarding pathways into the ground water. Interviews with farmers and chemical analyses show that application of manure leads to low concentrations (<100 ng/l) of Sulfadimidin and Sulfadiazin in most of the investigated samples. Sulfamethoxazol was found above 100 ng/l and likely originated from sewage of nearby small scale wastewater treatment plants. Sulfamethoxazole and its main metabolite could be detected within the plants; additionally, the sewage tracer acesulfam-K was detected in the groundwater. © 2016 Springer-Verlag Berlin Heidelberg

In recent years, human pharmaceutical substances have been increasingly detected in the aquatic environment. Specific attention has been drawn to the occurrence of pharmaceutical substances at bank filtration sites which are used for drinking water production. In the course of the authorisation application for new pharmaceutical compounds, an environmental risk assessment is required. Currently, the expected concentration of the human pharmaceutical compound in groundwater at bank filtration sites is calculated following the guideline Pre-Authorisation Evaluation of Medicines for Human Use issued by the European Medicines Agency (EMEA 2006). A simple estimation is applied: The predicted environmental concentration (PECGW) is the predicted environmental concentration in surface water (PECSW) multiplied with 0.25. A new approach considering the hydraulic and hydrogeological characteristics of bank filtration sites as well as transport processes is presented in this study. First, a numerical groundwater flow model was developed to simulate the groundwater flow processes at bank filtration sites in general. Flow times were calculated as a function of the hydraulic and hydrogeological parameters: hydraulic conductivity, shore-well distance, screen depth and extraction rate. In a second step, the PECGW was calculated based on the compound concentration in surface water and the modelled groundwater flow times considering linear sorption and first-order decay. Sorption and degradation can only be calculated based on the data provided by the pharmaceutical company in the course of the authorisation application. The current approach following the EMEA guideline invariably connects the PECGW with the PEC SW without considering sorption and/or degradation processes. We introduce an approach that incorporates the hydraulic process bank filtration and the main transport processes sorption and degradation. The new approach is compound specific as well as aquifer, flow and transport specific resulting in a more realistic PECGW value compared to the old approach. © 2010 Springer Science+Business Media B.V.

Throughout the authorization application for new pharmaceuticals an environmental risk assessment is required. Currently, the expected concentration of human pharmaceuticals in groundwater at bank filtration sites is calculated following a guideline issued by the European Medicines Agency (EMEA).

A new approach considering the hydraulic and hydrogeological characteristics of bank filtration sites and transport processes is presented. First, a numerical model was developed to simulate groundwater flow as a function of hydraulic and hydrogeological parameters at bank filtration sites. Second, the PEC gw was calculated based on the compound concentration in surface water and the modelled groundwater flow times considering linear sorption and first-order decay. Sorption and degradation can be calculated based on the limited data provided by the pharmaceutical company throughout the application. Copyright © 2011 IAHS Press.

For active drug substances, a mathematical simulation of the contamination from surface waters into groundwater through bank filtration was realized. The results could be verified on the basis of measured concentrations in known locations.


The depth to shallow groundwater tables in the forest areas of the state of Brandenburg was computed within areas of unconfined groundwater as the difference between the groundwater level and the ground-surface level. Special attention had been dedicated to the digital processing of the data in order to make the investigations technically comprehensible and reproducible for future uses with better or updated data. The depth to the groundwater table was computed in four typical hydrologic reference periods when flood or low water had prevailed. In addition to fixed-day measurements of groundwater and surface water levels, other water-level data were also integrated in the analysis and were related to the reference periods by statistical methods. The results are used in an interdisciplinary project of the Eberswalde Forestry Competence Centre, where they are used to solve forest-ecological and sylvicultural problems.


Due to high nitrogen concentrations, two groundwater bodies in Northern Brandenburg were classified under the heading "poor (chemical) condition" according to the Water Framework Directive of the European Commission. These evaluations of the "Landesumweltamt Brandenburg" were based on several investigations that compared the hydrogeochemical data with the quality norm for nitrate and with the threshold value for ammonia from the European Groundwater Directive. By sampling with direct push techniques, we re-analysed the extent of contamination in order to decide whether the water quality could be improved in a cost-effective manner. Based on the newly established data set, the area of contamination could be more precisely delineated with geostatistical techniques. This helped to determine whether the previous evaluation of local groundwater quality was still valid. © 2010 Springer-Verlag.

For the castle chain of lakes near Penkun in the southeast of Mecklenburg-Vorpommern, an elevation in the lake water surface levels is planned. Sites for possible groundwater abstractions were explored hydrogeologically. Reason for these considerations was the decrease of the water level of the castle lake-chain of lakes.
