  1. 16. Hydrogeological and geochemical assessment of aquifer systems with geogenic arsenic in Southeastern Bangladesh : Targeting low arsenic aquifers for safe drinking water supplies in Matlab

    Författare :Mattias von Brömssen; Prosun Bhattacharya; David Polya; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Arsenic; Bangladesh; drinking water; groundwater; sustainability; geochemistry; hydrogeology; modelling;

    Sammanfattning : Naturally occurring arsenic (As) in Holocene aquifers in Bangladesh have undermined a long success of supplying the population with safe drinking water. Arsenic is mobilised in reducing environments through reductive dissolution of Fe(III)-oxyhydroxides. LÄS MER

  3. 17. Towards sustainable water use in industry: a case study of the oil refinery industry in Kazakhstan

    Författare :Ivan Radelyuk; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; industrial wastewater; oil refinery; Kazakhstan; groundwater contamination; groundwater modeling; contamination transport modeling; Sustainable water use; Environmental Impact Assessment; Circular Economy;

    Sammanfattning : The concept of “Sustainable water use” (SWU) aims to assure three pillars of sustainability related to the water sector: the social, environmental, and economical. Industrial development, especially in developing countries, requires an adequate response, as industrial activities are recognized as one of the major sources of water pollution, what leads to deterioration of environmental safety and wellbeing of the society.

  4. 18. Economic Project Risk Assessment for Sustainable Choice Of REmediation (SCORE) in Construction Projects

    Författare :Petra Brinkhoff; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; probabilistic risk analysis; sustainability assessment; construction companies; project risk assessment; cost-benefit analysis;

    Sammanfattning : Contamination of soil and/or groundwater is a problem all over the world. There is a desire from politicians and the supervisory authorities to tackle the contamination problem in order to protect future generations. LÄS MER

  5. 19. The role of the hydrological cycle in forest ecosystems : flow path, nutrient cycling and water-carbon interaction

    Författare :Yanzi Yan; MERGE: ModElling the Regional and Global Earth system; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; flow path; DOC concentration; groundwater; photosynthesis; Amazon rainforest; catchment geomorphology;

    Sammanfattning : Forest ecosystems, covering over a third of land on the Earth, play a significant role in the global hydrological cycle, and influence soil erosion and climate change. However, the distribution, movements, quality of water, and hydrological processes in forested ecosystems are not well understood yet. LÄS MER

  7. 20. Estimations of Hydrogeological Properties in Vulnerability and Risk Assessments

    Författare :Lars Rosen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; groundwater; Markov; conceptual model; Bayes; risk; vulnerability;

    Sammanfattning : The main objective of this thesis was to evaluate and develop approaches for hydrogeological vulnerability and risk assessments, starting with scant data and updating the results as new information becomes available. This work was performed within three separate projects between 1989 and 1995. LÄS MER
