Within Work Area 5 of the DEMEAU project, selected innovative technologies and tools for emerging contaminants removal and monitoring are assessed in their environmental and economic benefits and impacts by using life-cycle based tools such as environmental Life Cycle Assessment (LCA) and economic Life Cycle Costing (LCC). Six case studies were assessed to quantify their environmental and economic profiles and formulate unique selling propositions to promote market uptake and implementation. These case studies include managed aquifer recharge for groundwater replenishment or for drinking water production in combination with advanced oxidation process, hybrid ceramic membrane filtration with powdered activated carbon for tertiary wastewater treatment, automatic neural net control systems to optimize membrane operation, ozonation of wastewater treatment plant effluent, and bioassays as screening tool for water quality monitoring. This report summarizes the study layout, input data, and results of LCA and LCC for all case studies and indicates unique selling propositions based on the outcomes of the assessment.

Different types of managed aquifer recharge (MAR) schemes are widely distributed and applied on various scales in the European countries, but no systematic categorization and compilation existed up to now. The European MAR catalogue presented herein includes a wide range of parameters, e.g. operational information, hydrogeological properties and water quality monitoring for different types of MAR. The database includes currently 270 MAR sites, but is neither a representative nor an exhaustive data compilation. Nevertheless, based on the available data it is shown that MAR plays an important role in the European water supply producing large water quantities for the domestic water supply.

The EU-funded R&D project DEMEAU addresses the fate of emerging pollutants in water and waste water treatment, e.g. Managed Aquifer Recharge (MAR). For MAR the objectives are to mobilize existing experience from different European study sites and to develop a systematic approach for the authorization of new recharge schemes in compliance with the European water and groundwater directives. The activities will cover the issue of infiltrating and injecting treated wastewater as well as developing guidance on optimum design and operation of infiltration facilities. In order to demonstrate the effects of typical existing European MAR systems onto groundwater availability and groundwater quality with specific focus on trace organics, a comprehensive relational database (catalogue) on European MAR systems was created to ensure efficient management of available data. By means of the built-in user forms, queries, and reports, database users are enabled to not only view and enter records but also to quickly process the data to extract needed information. In total, 59 different parameters were selected in order to describe about 270 documented MAR sites in 23 countries in Europe. These parameters were then divided up into four main groups (general information, technical data, hydrogeological parameters and monitoring activities) plus references. The database was created using standard software (MS ACCESS) and references were managed by open source software (JABREF). The compiled data on European MAR sites was taken from a variety of different source types, including scientific articles, books, PhD, diploma and master's theses, presentations, technical documents, reports from previous national and EU research projects, personal communication with specialists, operators and water authorities, community and operator websites, newspaper articles, and Google Earth (for geographic coordinates to create overview maps). On the basis of this database a classification system for the MAR sites found in Europe will be developed that can be used for deriving site-specific pre-requisites and design criteria as guidance for the authorization of for new sites.
