    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Hannan Hadodo; [2017]
    Keywords : Spring; water quality; restoration;

    Abstract : Twenty springs in the central parts of Vallentuna municipality have been studied to determine their present water qualities and suggest actions that could be taken to improve the water quality and availability of the springs. The measured parameters are the water volume, the water flow, the water temperature, the pH-value, the electrical conductivity, the chloride concentration, the alkalinity and the CODMn. READ MORE

  3. 22. Grön-blå gator : en undersökande studie över möjligheterna att använda regnbäddar i gatumiljöer - med utgångspunkt i ett gestaltningsförslag för Vasagatan i Kristianstad

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Wille Helmbold; [2016]
    Keywords : regnbäddar; biofilter; hållbar dagvattenhantering; landskapsarkitektur; rain gardens; bio-retention; sustainable stormwater management; landscape architecture;

    Abstract : I miljöer som till hög andel utgörs av hårdgjorda ytor kan regnvatten inte infiltrera ned i marken som normalt, utan stora mängder blir istället till dagvatten. Hanteringen av dagvatten sker idag generellt genom att det transporteras iväg via brunnar och underjordiska ledningar till reningsverk och recipienter utanför städerna. READ MORE

  4. 23. A hydrochemical investigation and socioeconomic assessment in Rio Zapomeca river basin focusing on arsenic contamination

    University essay from Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet; Lunds universitet/Riskhantering (CI)

    Author : Axel Hagström; Anton Rydstedt; [2015]
    Keywords : geology; groundwater; drinking water; water contamination; water treatment; value of statistical life; cost-benefit-analysis; Resistivity; Arsenic; Risk; Technology and Engineering;

    Abstract : The awareness of problems concerning arsenic contaminated drinking water sources has during recent years increased. WHO (World Health Organization) decided in 1993 to lower the recommended limit of arsenic in drinking water from 50 μg/l to 10 μg/l, mainly due to observations of its carcinogenicity. READ MORE

  5. 24. Groundwater modelling of Färgaren 3 in Kristianstad - Simulations in MIKE SHE based on two extraction scenarios and different hydrogeological settings
