<p><span>A need exists for a reliable and long-term water supply for the 285,000 inhabitants of the Turku area in </span>southwestern<span> </span>Finland<span>. In response to this need, there are plans to replace the present water supply from the surface sources with artificially infiltrated groundwater from a Quaternary esker </span>aquifer<span> called the </span>Virttaankangas<span> </span>aquifer<span>. New sedimentological studies of the </span>Virttaankangas<span> area have revealed the complexities of the esker system and its surrounding glacial, glaciofluvial, and glaciolacustrine geology. This led to the characterization of the hydrogeological units of the </span>aquifer<span>, the result of which has been a </span>three<span>-</span>dimensional<span> (3-D) truly integrated solids model that represents the geometry, interrelationships, and hydrostratigraphy of the study area. The 3-D model was made with Earth Vision </span>geologic<span> </span>modeling<span> software. The 3-D geological model of the </span>Virttaankangas<span> </span>aquifer<span> can be used for planning the infiltration of river water into the </span>aquifer<span> and to understand the </span>geologic<span> and geographic boundaries of the hydrogeologic units hosting the groundwater reserve and the </span>geologic<span> relationships between the units. Another major outcome of this study is a powerful </span>visualization<span> tool that will be provided to municipal and government authorities who must understand the </span>geologic<span> complexities involved with water-resource planning prior to their decision making.</span></p>
