Fig. 2. Schematic drawing of the soil sections at point G18 and in the vicinity of the point G17 at the Trollberget site. At point G18, the soil profile comprised following units: Unit A; fine sand (filling soil), Unit B; coarse sand (filling soil), Unit C; garbage-containing sand (filling soil), Unit D; layer with very low water conductivity, high oil and organic matter content (filling soil), Unit E; fine littoral sand, Unit F; coarse sand. A layer of perched ground water (P), approximately 0.2 m in thickness, above the unit D is indicated. The approximate level of the ground water is indicated with an arrow. In the vicinity of point G17, the soil profile comprised the following units: Unit A consisted of coarse sand (filling soil), unit B of medium to fine-grained littoral sand, and unit C of shell-rich, littoral, silty sand. The position of the soil monitoring sensors (black rectangles), piezometer (DEMOGM20), and the ground water monitoring sensors in the piezometer (black circles) installed in the vicinity of points G17 at the Trollberget site, and the highest and the lowest level of ground water (arrows) from 12.5.2004 to 31.1.2005 in the piezometer, are indicated.
