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

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

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

   Abstract : 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

   University essay from Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

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

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

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

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

   Abstract : 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 . READ MORE

6. 5. CFD Study of Different Aircraft Cabin Ventilation Systems on Thermal Comfort and Airborne Contaminant Transport : A Study on Passenger Thermal Comfort and Indoor Cabin Air Quality.

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Logeshkumar Srinivasan Venkatesan; Abhishek Raina; [2020]
   Keywords : ;

   Abstract : Aircraft Cabin Ventilation systems are crucial for not only maintaining a fresh supply of air but also help in proper air distribution control and reducing airborne pathogen contamination. Passenger thermal comfort is of vital importance for a comfortable cabin environment and thus the need to measure environmental parameters such as velocity and temperature stratification for different ventilation systems is paramount.
