    Sammanfattning : This Bachelor thesis is assigned to interpret and visualize the degree of contamination and degradation of chlorinated aliphatic hydrocarbons (CAH) in relationship with groundwater chemistry and signals from geophysical surveys. The relationships between pollutant, chemistry data and geophysical surveys were tested through linear regression. LÄS MER

    Sammanfattning : A facility for preservation of wooden rail road sleepers has been operating at the railway yard in Nässjö between 1918 and 2005. The main preservative used at the site was creosote which contains polycyclic aromatic hydrocarbons (PAH) that can be harmful to humans and the environment. LÄS MER

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

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

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

    Sammanfattning : 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.

  5. 19. Modeling for delineation of protection areas for shallow groundwater resources in peri-urban areas.

    Master-uppsats, KTH/Mark- och vattenteknik

    Författare :Ting Liu; [2012]
    Nyckelord :Shallow groundwater modeling; drain; COMSOL; ALE; Peri-urban; Contaminant; Large dimension;

    Sammanfattning : Bwaise III in Kampala, Uganda is a densely populated informal settlement with a shallow groundwater table and inadequate basic services. High risk of groundwater contamination will bring health problem to the local residents. LÄS MER

  7. 20. Impact on Soil and Groundwater from Road Maintenance and Traffic: Initial Study of the E18 Highway.

    Master-uppsats, KTH/Mark- och vattenteknik

    Författare :Robert Earon; [2011]
    Nyckelord :Geophysics; Resistivity; Hydrogeology; Contaminant Transport; Contaminant Distribution; Soil and Water Chemistry;

    Sammanfattning : The investigation of environmental impacts of 16 different contaminants originating from the E18 Highway (17 000 AADT) were carried out over the first six months of the highway‘s operational life. Investigative methods used include electrical resistivity surveying, water chemistry analyses, soil analyses, distribution modelling and transportation modelling. LÄS MER
