  1. 1. High levels of nickel from sulphide soil in Umeå's raw water : Modeling of groundwater flow and mass transport in Forslunda aquifer

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Merhawi Belai; [2024]
    Nyckelord :nickel; sulfide; sulphide; groundwater; modeling; mass transport; Feflow; Umeå; nickel; sulfid; monosulfid; grundvatten; modellering; masstransport; Feflow; Umeå;

    Sammanfattning : The raw water in some of Umeå's abstraction wells has shown high nickel levels for more than a decade. The cause has not been determined but there is an investigation from 2010 where the results indicate sulphide clay found adjacent to two basins used for artificial infiltration. LÄS MER

  2. 2. Groundwater Modelling in southeast Cambodia - Facing irrigation and groundwater level changes during a pandemic

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Svea Bertolatus; [2024]
    Nyckelord :Cambodia; GMS Modflow; Groundwater modelling; irrigation; Mekong; Prey Veng; Svay Rieng; Technology and Engineering; Earth and Environmental Sciences;

    Sammanfattning : In the Mekong region, sustainable water resource management is a significant challenge for all countries involved. In Cambodia, where rice production is crucial for household food security and export, groundwater is increasingly used for irrigation during the dry season, leading to higher rice yields. LÄS MER

  3. 3. Modelling the Water Table in a Bog

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Tobias Bowley; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Over the past five years, an ongoing study at INES, Lund University, have examined the encroachment of trees and vegetation into a bog ecosystem in northern Scania, Sweden. While several factors have been identified as contributing to this ecological transformation, including, nutrient availability, and climate, the hydrological aspect remains a key area of investigation.

  4. 4. Infiltration av renat grundvatten : Platsspecifika parametrar vid konstgjord infiltration

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Elina Linerudt; [2023]
    Nyckelord :grundvatten; hydrogeologi; infiltration;

    Sammanfattning : Groundwater is a valuable source of drinking water and projects that manages groundwaterneed to prevent complications on the water’s characteristics. In an infrastructural project,groundwater reduced from elevated levels of nitrate needed to be recharged into the aquifer inthe area. LÄS MER

  5. 5. PFAS Contamination in Groundwater; Evaluating Factors Influencing the Impact of PFAS Contamination on the Drinking Water Source in a Holistic Approach _________________________

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Anna Söderman; [2023]
    Nyckelord :PFAS; Contamination; Firefighting Foam; Groundwater; Drinking Water; Technology and Engineering;

    Sammanfattning : Aqueuous Film Forming Foam (AFFF) containing Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS) is one of the major sources of groundwater contamination in Sweden. Groundwater contamination caused by the use of AFFF in correlation to fire training events was investigated in Kallinge, Sweden. LÄS MER
