  1. 1. 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

  3. 2. Spatial analysis of arsenic and fluoride mobilization in groundwater around Mount Meru, northern Tanzania

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Henriette Nishimwe; [2023]
    Keywords : Arsenic; Fluoride; Groundwater; Mobilization; Mount Meru; Geochemical and Spatial Modelling; Arsenic; Fluoride; Groundwater; Mobilization; Mount Meru; Geochemical and Spatial Modelling;

    Abstract : In Tanzania, approximately 76% of the drinking water supplies is dependent on groundwater sources. However, the groundwater in north Tanzania is susceptible to contamination by arsenic and fluoride. This study examines the spatial analysis of arsenic and fluoride mobilization in groundwater around Mount Meru, located in northern Tanzania. READ MORE

  4. 3. Groundwater modeling of Krycklan catchment and evaluation of the groundwater discharge distribution

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Sandra Edström; [2022]
    Keywords : groundwater modelling; groundwater flow; Krycklan catchment; topography-controlled groundwater surface; evapotranspiration; groundwater discharge; groundwater recharge; grundvattenmodellering; grundvattenflöde; Krycklan avrinningsområde; topografi-kontrollerad grundvattenyta; evapotranspiration; grundvattenutflöde; grundvatteninfiltration;

    Abstract : This thesis aimed to evaluate the groundwater discharge distribution in the Krycklan catchment by developing a groundwater flow model using COMSOL Multiphysics and assuming a topography- controlled groundwater surface. Previous research has shown that the groundwater surface can be modeled as a subdued replica of the topography in humid climate regions where the permeability of the subsurface is low and where the groundwater surface is shallow.

  5. 4. Quantification of peat volume change in Northern peatlands : A study of mires capacity to swell and shrink and its relation to mire age and land management

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

    Author : Anna Engman; [2022]
    Keywords : peatland; peat volume change; ecohydrology; specific storage; peatland age; torvmark; myr; torvvolymförändring; ekohydrologi; specifik magasinkoefficient; ålder;

    Abstract : Peatlands are important ecosystems that provide ecohydrological functions related to carbon storage and cycling, water quality, flood attenuation, and groundwater recharge. One key characteristic that gives peatlands these functions is the capacity to swell and shrink upon wetting and drying, commonly referred to as peat volume change. READ MORE

  6. 5. Groundwater Crisis in Southern Rural India : Understanding Farmers’ Perspectives and Local Participatory Mitigation Strategies

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Rohini Srivyshnavi Korlakunta; [2022]
    Keywords : water conservation and management; public participatory measures; understanding farmers’;

    Abstract : India is the largest user of groundwater in the world with an estimated utilization of 230 cubic kilometers per year which is over a quarter of the global total. More than 60% of irrigated agriculture is dependent on groundwater and when there is no adequate recharge of groundwater due to over exploitation and lesser rainfall, water scarcity and thus drought occurs.
