  1. 1. Distribution and mobilization of heavy metals at an acid mine drainage-affected region, South China

    Master-uppsats, Linköpings universitet/Tema Miljöförändring

    Författare :Chen Luo; [2020]
    Nyckelord :acid mine drainage; arsenic; cadmium; geochemical modeling; heavy metals; lead; principal component analysis;

    Sammanfattning : Dabaoshan Mine Site (DMS) is the biggest polymetallic mine in South China. The Hengshi River receives acid mine drain (AMD) waste leaching from the tailings pond and run-off from the treatment plant which flows into the Wengjiang River, Beijiang River, before discharging into the Pearl River.

  2. 2. Saltwater Intrusion in Fractured Crystalline Bedrock Aquifer. - A Case Study on Koster Islands, SW Sweden

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Sibhat Afewerki; [2019-10-30]
    Nyckelord :saltwater intrusion; fractured bedrock aquifers; DRASTIC; vulnerability mapping; Koster Islands; slatvattenintrång; Akvifer i uppsprucken berggrund; sårbarhetskartläggning; Kosteröarna;

    Sammanfattning : Saltwater intrusion (SWI) is one of the significant threats in many coastal areas, mainly drivenby anthropogenic hazards (over-pumping) and climate change (sea level rise). So far, there havebeen extensive research and techniques to understand and minimize SWI. LÄS MER

  3. 3. Grundvattenpåverkan kring schakter. - En jämförelse mellan olika analytiska beräkningsmetoder

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Axel Barkestedt; [2019-10-30]
    Nyckelord :;

    Sammanfattning : To be able to predict the effects on groundwater related to drawdown is of great importance to makesure that protected objects, such as drinking water wells and vulnerable ecosystems, are not affected.To predict the size of the area that will be affected by a drawdown, an analytical solution is often usedto calculate the radius of influence.

  4. 4. Grundvatten i Aitiks gruvområde : En utvärdering av grundvattenkvalitet och provtagningspunkter

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Anna Bergström; [2019]
    Nyckelord :Groundwater; Copper mine; Sulphide oxidation; Groundwater management; Mine-water chemistry;

    Sammanfattning : The aim of this study was to evaluate the quality of the groundwater around the Aitik copper mine- one of Europe’s largest copper mine located 15 km outside of Gällivare, Sweden - as well the placement of the groundwater pipes around the area. The study also included a survey of what kind of terms, regarding groundwater that may become relevant in the future for an activity of Aitik’s size and type. LÄS MER

  5. 5. Chemical Stabilization of Arsenic in Contaminated Soil under Low Redox Conditions

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Eva Smedborn Pausson; [2019]
    Nyckelord :;

    Sammanfattning : Remediation techniques for arsenic contaminated soil have previously focused mostly on the surface soil layers where aerobic conditions are prevalent. In this master thesis, chemical stabilization by adding zero-valent iron (Fe(0)) and calcium oxide (CaO) to an arsenic-contaminated soil under low redox conditions have been studied through up-flow percolation tests.
