  1. 16. Aquifer Thermal Energy Storage : Impact on groundwater chemistry

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Julian Kolesnik Lindgren; [2018]
    Keywords : aquifer thermal energy storage; ATES; groundwater; groundwater chemistry;

    Abstract : Groundwater is potentially a useful source for storing and providing thermal energy to the built environment. In a nordic context, aquifer thermal energy storage, (ATES) has not been subject to a wider extent of research concerning environmental impact. READ MORE

  3. 17. Application of ERT and IP for localisation of chlorinated hydrocarbons at a former dry-cleaning facility

    University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Hedda Jönsson; Anna Wiberg; [2017]
    Keywords : Chlorinated hydrocarbons; PCE; Hagforstvätten; Geophysics; Resistivity; Chargeability; Geological features; Man-made structures; Technology and Engineering; Earth and Environmental Sciences;

    Abstract : At Hagforstvätten a dry-cleaning facility operated 1970 – 1993 and leached huge amounts of tetrachloroethene (PCE) to soil and groundwater. This study was conducted at the contaminated site and focused on applying the geophysical methods Electrical Resistivity Tomography (ERT) and Induced Polarization (IP) to investigate if it was possible to locate source zone, degradation zones and groundwater plumes of PCE.

  4. 18. A geophysical survey (TEM; ERT) of the Punata alluvial fan, Bolivia

    University essay from Lunds universitet/Geologiska institutionen

    Author : Joakim Mårdh; [2017]
    Keywords : electromagnetic; geophysics; TEM; Punata; alluvial fan; Earth and Environmental Sciences;

    Abstract : The Punata alluvial fan, situated in central Bolivia (Valle Alto) between the Altiplano and the lowlands, is an important aquifer for the local rural population. Due to rapid development and population growth in the area, the demand for fresh water has increased in recent year. READ MORE

  5. 19. Downhole Physical Property Logging of the Blötberget Iron Deposit, Bergslagen, Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Philip Johansson; [2017]
    Keywords : Borehole logging; resistivity logging; magnetic susceptibility; magnetite; Bergslagen; Borrhålsloggning; geofysik; apatitjärnmalm; Bergslagen;

    Abstract : Geophysical methods are frequently applied in conjunction with exploration efforts to increase the understanding of the surveyed area. Their purpose is to determine the nature of the geophysical response of the subsurface, which can reveal the lithological and structural character. READ MORE

  6. 20. Applying Geoarchaeological Methods on an Iron Age site : Part two of a two-part study discussing Archaeological Prospection for Ytings, Gotland

    University essay from Umeå universitet/Institutionen för idé- och samhällsstudier

    Author : Jessica Coleman; [2017]
    Keywords : Geoarchaeology; Gotland; Iron Age; Magnetic Susceptability; Phosphate analysis;

    Abstract : Geoarchaeology has had a long history within archaeology around the world, but not so much so in Gotlandic archaeology. This study is aimed at drawing attention to this by using magnetic susceptibility (MS) and phosphate (P) analysis of an Iron Age site at Ytings, Gotland. READ MORE
