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

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

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

    Abstract : 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. READ MORE

  3. 2. Methodology for Stored Heat “Heat In Place” (HIP) assessment of geothermal aquifers – Exemplified by a study of the Arnager Greensand in SW Scania

    University essay from Lunds universitet/Geologiska institutionen

    Author : Oskar Sundberg; [2023]
    Keywords : geothermal energy; geothermal resource assessment; geothermal potential; volume method; volumetric method; recovery factor; direct use; direct heat; Mesozoic aquifers; Earth and Environmental Sciences;

    Abstract : In the sedimentary bedrock of southwest Scania, located in the southernmost part of Sweden, there are several low-enthalpy Mesozoic sandstone aquifers situated at different depths. These aquifers collectively hold the potential for direct-heat geothermal utilization. READ MORE

  4. 3. Potential policy projects for decreasing fluoride concentrations in the groundwater of Aguascalientes, Mexico : a cost-benefit analysis

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Elice Fällström; [2022]
    Keywords : aguascalientes; cost-benefit analysis; fluoride removal; centre pivot irrigation; sustainable development; environmental policy;

    Abstract : Reductions in groundwater quality due to aquifer depletion is a growing issue globally and will become more prominent with continued climate change and population growth. Dry regions are particularly vulnerable to this issue due to their reliance on groundwater for water supply. READ MORE

  5. 4. Long-term Effect of Metallic Iron Sorbents on Arsenic Mobility in an Anoxic Aquifer : An assessment based on long-term column experiments

    University essay from SLU/Dept. of Soil and Environment

    Author : Stéphanie Nyström; [2022]
    Keywords : Zero valent iron; ZVI; Remediation; Anoxic; Column tests; ICP-MS;

    Abstract : Zero valent iron (ZVI) sorbents have successfully remediated soils burdened with different groups of contaminants. When working to alleviate arsenic (As) contamination, the location-specific subsurface chemistry greatly affects the efficiency of the sorbents as it controls the speciation of As and the transformation of the ZVI, as well as the interaction between these (remediating mechanisms).

  6. 5. Effectiveness of Barrier Well by Pumping Ratio Control for Saltwater Intrusion: Lab-Scale Experiments and Numerical Modeling

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Shinichi Ozaki; [2021]
    Keywords : Saltwater intrusion; Barrier well; Pumping ratio control; Production well; salinity-affected coastal aquifer; Critical groundwater pumping ratio; Technology and Engineering;

    Abstract : Saltwater intrusion is the most challenging problem in coastal regions. To prevent saltwater intrusion, saltwater pumping from a barrier well is widely applied, which is a direct abstraction of intruded saltwater from a coastal aquifer. Owing to its easy installation, many studies have been carried out. READ MORE
