ABSTRACT
Several tests are currently under execution at the Cornelia site within the framework of an European Project. One of the existing Aquifer-Storage-and-Recovery (ASR) wells was previously selected to perform specific experiments. The main objective is to study clogging around the ASR well itself, although redox reactions and water-aquifer material interactions are also being examined. Three different tasks were scheduled: analysis of recharge water and groundwater, analysis of soil cores, and completion of field tests. Both water and soil investigations served to obtain the basic parameters, to identify the aquifer characteristics and to assess some clogging-related properties. Still, natural heterogeneity and main hydraulic connectivity can not be derived through laboratory analysis. Therefore, various field tests are being carried out. The approach presented here is innovative as regards two aspects: first, a-priori relevant clogging parameters have already been measured, and, second, specifically derived numerical codes will be applied to obtained data.
