  1. 16. Long-term Effect of Metallic Iron Sorbents on Arsenic Mobility in an Anoxic Aquifer : An assessment based on long-term column experiments

    University essay from SLU/Dept. of Soil and Environment

    Author : Stéphanie Nyström; [2022]
    Keywords : Zero valent iron; ZVI; Remediation; Anoxic; Column tests; ICP-MS;

    Abstract : Zero valent iron (ZVI) sorbents have successfully remediated soils burdened with different groups of contaminants. When working to alleviate arsenic (As) contamination, the location-specific subsurface chemistry greatly affects the efficiency of the sorbents as it controls the speciation of As and the transformation of the ZVI, as well as the interaction between these (remediating mechanisms).

  3. 17. A comparison of 2D and 3D resistivity surveys for 3D inversion imaging

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Julia Cavell; [2022]
    Keywords : ;

    Abstract : Following study focuses on electrical resistivity surveying and how it can be used as an exploration method to increase knowledge of subsurface structures. Future scenarios with increasing population and rapid urbani-zation, put high demands on reliable infrastructure; safe foundations, un-derground structures, environmental safety and access to resources.

    Abstract : Malfunctioning landfills are a globally sprawled problem. The Olusosun landfill in Lagos, Nigeria is not an exception. It is located in the middle of the city, nearby groundwater resources used to supply drinking water for the inhabitants in Lagos. READ MORE

  5. 19. POLYAROMATIC HYDROCARBONS IN HYDROCHARS : HYDROTHERMAL CARBONIZATION OF SEWAGE SLUDGE

    University essay from Umeå universitet/Kemiska institutionen

    Author : Björn Sundqvist; [2021]
    Keywords : ;

    Abstract : Sewage sludge is an inevitable by-product from waste water treatment plants. Sludgemanagement is a difficult task since sludge has a high moisture content, poordewaterability and generally contain heavy metals, pharmaceutical residues,polyfluorinated alkyl substances (PFAS) and organic pollutants.

  6. 20. Modeling groundwater flow using COMSOL to understand the water cycle dynamics and climate change impacts for future groundwater availability in the Matlab region, Southeastern Bangladesh

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Oscar Vandromme; [2021]
    Keywords : Aquifer-Arsenic contamination-Climate change-Groundwater elevation-Model-Sustainability;

    Abstract : Arsenic contamination has been a growing concern for many countries, especially Bangladesh. In Bangladesh, one of the most arsenic-contaminated regions is Chandpur. In this study, groundwater data were analyzed in order to create models to improve knowledge on groundwater flow dynamic in a specific area of Chandpur called Matlab. READ MORE
