21. Groundwater flow modelling to address hydrogeological response of a contaminated site to remediation measures at Hjortsberga, southern Sweden
University essay from Lunds universitet/Geologiska institutionenAbstract : Pentachlorophenol (PCP) is a chlorinated aromatic compound that was commonly used for treatment of wood against microbial degradation before it got banned in the 1970s. Due to its solubility in water, PCP is a common groundwater contaminant around old sawmills, for example near Hjortsberga in southern Sweden where this study was performed.. READ MORE

22. Evaluating locations for subsurface dams : Case study on Storsudret, Gotland
University essay from KTH/Hållbar utveckling, miljövetenskap och teknikAbstract : Due to precipitation poor winters and springs and over-exploitation of groundwater reserves during the summer months as a consequence of tourism, the island of Gotland has experienced fresh water shortages during recent years which has led to harsh restrictions in the use of municipal water. In order to find a solution to the islands fresh water problems, the region of Gotland and the Swedish Environmental Institute (IVL) have initiated a project in which the southernmost part of Gotland, Storsudret, will be used as a test site for new methods of sustainable freshwater storage and extraction methods.
