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

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Väg- och vattenbyggnad (CI); Lunds universitet/Teknisk geologi

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

   Sammanfattning : 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. LÄS MER

3. 2. Modelling of Fluid Flow and Contaminant Transport in Fractured Rock : Case Study

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

   Författare :Ebba Pegestam; [2022]
   Nyckelord :Contaminant transport; Discrete Fracture Network; Geology; Geohydrology; Groundwater transport; Fracture; Drinking water; Contamination; Föroreningar; flödestransport; spricknätverk; geologi; geohydrologi; grundvattentransport; sprickor; dricksvatten;

   Sammanfattning : Drinking water contamination is a big concern in Sweden and is commonly traced back to being waste from former manufacturing industrial sites. Pollutants in the topsoil can be remediated by several techniques, such as decontamination or excavation but the toxins already enclosed in the bedrock cannot be treated the same and is harder to track possible contaminant pathways.

4. 3. Evaluation of distribution coefficients (KOC and Kd) for per- and polyfluoroalkyl substances

   Magister-uppsats, Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

   Författare :Nika Nordanstorm; [2021]
   Nyckelord :PFAS; PFOS; organic contaminant; sorption; Kd; KOC; distribution coefficient; solubility; mobility; environmental fate; environmental transport; contaminated site; hydrophobic interaction; electrostatic interaction;

   Sammanfattning : The dominating factors affecting sorption of per- and polyfluoroalkyl substances (PFAS) remain subject of research and debate. Traditionally, distribution coefficients (e.g. LÄS MER

5. 4. Analysis of seepage, contaminant transport, compaction and safety of the Zhaoli ditch dam, a tailing reservoir : A modeling study of a tailing reservoir with GeoStudio

   Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

   Författare :Veronika Wei Wang; [2021]
   Nyckelord :upstream method; Geostudio; tailings reservoir; tailings dam; dam; seepage; contaminant transport; compaction; stability; damm; föroreningstransport; vattenläckage; stabilitet; säkerhet;

   Sammanfattning : Inthe mining industry people remove rock from the ground to obtain a metal ore. Afterprocessing , the uneconomic fraction called tailings is deposited as a slurry in large reservoirs . LÄS MER

7. 5. Inventering enligt MIFO fas 1 av fyra nedlagda deponier i Åstorps kommun

   Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

   Författare :Linn Möller; [2020]
   Nyckelord :MIFO; Förorenade områden; Deponier; Deponigas; Earth and Environmental Sciences;

   Sammanfattning : In Sweden, it is every municipality’s responsibility to identify and risk evaluate disused landfills located within the municipality. The purpose of this study is to risk evaluate four disused landfills in Åstorps kommun, Scania, for which a risk evaluation hasn’t previously been done. LÄS MER
