  1. 6. Hydrus-1D as a tool to understand contamination of an aquifer: A case study in the Central Valley of Cochabamba

    University essay from Lunds universitet/Teknisk geologi

    Author : Theo Nyberg; [2019]
    Keywords : Technology and Engineering;

    Abstract : In water resource management, it is of importance to be able to predict how different activities might contaminate aquifers. For this kind of application, numerical modelling of water and solute transport can be a useful tool. READ MORE

  4. 8. Evaluation of stimulated reductivedechlorination in situ of chlorinatedsolvents at a site in Huddinge : using principal component analysis, partialleast square regression and degradation

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Karin Ljungberg; [2018]
    Keywords : Reductive dechlorination; DNAPL; stimulated bioremediation; chlorinated solvents; Reduktiv deklorering; DNAPLS; stimulerad biologisk behandling; klorerade lösningsmedel;

    Abstract : The method of using stimulated reductive dechlorination when remediating sites contaminated with chlorinated solvents is not unusual, but not many studies have been done on the overall process outside of a controlled environment. In order to investigate the process, principal component analysis (PCA) and partial least square (PLS) regression was used to identify the most important parameters for the degradation of the chlorinated solvents.

  5. 9. Advective transport times in the river basin of lake Vombsjön

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

    Author : Sarha Rodin Holst; Olivia Svensson; [2016]
    Keywords : Lake Vombsjön; advective transport; decentralized sewer systems; contaminant transport; transport times; ArcMap; Earth and Environmental Sciences;

    Abstract : The raw water source lake Vombsjön is situated in the center of southern Scania and provides drinking water by artificial groundwater recharge for approximately 450 000 inhabitants each day. More than 2800 households within the catchment of lake Vombsjön treats their domestic wastewater with a decentralized sewer system. READ MORE

  6. 10. Modeling groundwater flow and PFOS transport. : A case study at the old fire drill site of Bromma Stockholm Airport.

    University essay from KTH/Mark- och vattenteknik

    Author : Joakim Persson; Niklas Andersson; [2016]
    Keywords : Bromma Stockholm Airport; PFOS; Visual MODFLOW; Geophysics;

    Abstract : At Bromma Stockholm Airport, fire drills have previously been performed at a location outside the current airport confinements. Fire drills were performed with extinguisher foams containing toxic perfluorooctanesulfonic acid (PFOS), which have polluted the site. Harmful effects of PFOS include but are not limited to damages to the endocrine system. READ MORE
