  1. 11. Modelling of Fluid Flow and Contaminant Transport in Fractured Rock : Case Study

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Ebba Pegestam; [2022]
    Keywords : Contaminant transport; Discrete Fracture Network; Geology; Geohydrology; Groundwater transport; Fracture; Drinking water; Contamination; Föroreningar; flödestransport; spricknätverk; geologi; geohydrologi; grundvattentransport; sprickor; dricksvatten;

    Abstract : Drinking water contamination is a big concern in Sweden and is commonly traced back to being waste from former manufacturing industrial sites. Pollutants in the topsoil can be remediated by several techniques, such as decontamination or excavation but the toxins already enclosed in the bedrock cannot be treated the same and is harder to track possible contaminant pathways.

  3. 12. Solubility of arsenic in untreated and ZVI-treated contaminated aquifer material

    University essay from SLU/Dept. of Soil and Environment

    Author : Oscar R. Davies; [2022]
    Keywords : Hjältevad; zerovalent iron; phosphate extraction; Oxalate extraction; Visual MINTEQ; geochemical modelling;

    Abstract : Arsenic (As) is a toxic element to all life and exists in nature both naturally and anthropogenically. Naturally As contaminated soils are formed due to high geogenic background As concentrations which is released when bedrock is eroded. Asia is a continent with a high amount of naturally As contaminated soils and groundwater. READ MORE

  4. 13. Geophysical Data from Norrbotten, Sweden - Evidence for the Presence of a Crustal Scale Fault?

    University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

    Author : Jimmy Markström; [2022]
    Keywords : Self-Organizing Maps; Magnetic Anomaly; Radioisotopes; Geological Faults;

    Abstract : The method of combining multiple geophysical, geological, or geochemical datasets can reveal patterns of otherwise hidden features in the Earth’s crust. This may aid in geological mapping, locating economic mineral deposits and for general anomaly/feature detection. READ MORE

  5. 14. The Swedish Oil Weapon : Storage of fuel in Sweden during the Cold War – Energy security and environmentally related aspects

The investigation focuses on the period 1938-1998 and considers the vital role of fossil fuel during a period when Sweden declared neutrality and independence. READ MORE

  6. 15. Energy efficiency measures in a typical Swedish single-family building from the 1960s

    University essay from Uppsala universitet/Byggteknik och byggd miljö

    Author : Emanuel Larsson; Raffaello Ljungqvist Baldesi; [2022]
    Keywords : energy system; building; energy efficiency measures; storage; solar panels; electricity demand; heating demand; insulation;

    Abstract : Many buildings built in the 1960s are inefficient when it comes to their energy use. A lot of them are also in need of renovating. Therefore, this project is aiming to investigate five different scenarios where the decrease in electricity demand is in focus. READ MORE
