  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. Modeling PFAS Transport in Groundwater - Exploring current approaches and evaluating parameter importance

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

    Author : Clara Eklund; [2023]
    Keywords : PFAS; Groundwater modeling; FEFLOW; Python; Machine learning; Technology and Engineering;

    Abstract : PFAS contamination in drinking water is a current problem, and new regulations for drinking water limits were recently implemented in each member country of the EU in January this year. Understanding the spread of PFAS in groundwater is therefore important to prevent it from reaching drinking water sources. READ MORE

  4. 3. Design and Optimisation of an Aquifer Storage and Recovery System - Options for long term storage under natural hydraulic gradients

    University essay from Lunds universitet/Teknisk geologi

    Author : Simon Kreipl; [2021]
    Keywords : Aquifer storage and recovery; well-field design; groundwater modelling; numerical modelling; FEFLOW; Technology and Engineering;

    Abstract : Aquifer storage and recovery (ASR) is a concept where water is stored in an aquifer during times when it is available, thus creating artificial groundwater, which can later be recovered by pumping when it is needed (Pyne, 1995). One ASR cycle consists of a injection, a standby and a recovery phase. READ MORE

  5. 4. Importance of dissolved organic carbon for transport of organic contaminants in groundwater

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Lisa Söderberg; [2013]
    Keywords : modeling; FEFLOW; sorption; KDOC; phenanthrene; DEHP; modellering; FEFLOW; adsorption; KDOC; fenatren; DEHP;

    Abstract : The need of understanding transport processes of contaminants in groundwater has grownalong with the discovering of contamination of soil and groundwater due to industrialization.Mobility of an organic contaminant in the soil is affected by its partitioning to dissolvedorganic carbon, DOC.
