  1. 1. Site Study of Fibrous Sediments in Sandviken, Ångermanälven River Estuary, Sweden

    Master-uppsats, Uppsala universitet/Naturresurser och hållbar utveckling

    Författare :Joanna Ghaderidosst; [2020]
    Nyckelord :Fiberbank; fiber-rich; fibrous sediment; pulp and paper industry; bearing capacity; FluMu; Penetrometer; Pollution; consolidation; gas; Fiberbank; fiberrik; fiberhaltigt sediment; pappersindustri; bärkraft; FluMu; penetrometer; förorening; gas;

    Sammanfattning : Pulp and paper industries in Sweden have since the end of the 19th century until late 70s been active in dumping wastewater into adjacent water bodies that have created fibrous sediments called fiberbank and fiber-rich sediment. Fiberbanks are large banks of predominantly organic material while fiber-rich sediment is fibrous sediment that has been mixed with bottom sediment. LÄS MER

  3. 2. Groundwater flow modelling to address hydrogeological response of a contaminated site to remediation measures at Hjortsberga, southern Sweden

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Adam Johansson; [2020]
    Nyckelord :PCP; Groundwater modelling; Permeable reactive barrier; Hjortsberga sawmill; Earth and Environmental Sciences;

    Sammanfattning : Pentachlorophenol (PCP) is a chlorinated aromatic compound that was commonly used for treatment of wood against microbial degradation before it got banned in the 1970s. Due to its solubility in water, PCP is a common groundwater contaminant around old sawmills, for example near Hjortsberga in southern Sweden where this study was performed.. LÄS MER

  4. 3. Development of monitoring program for water safety in small-scale water treatment plants in rural areas of Ecuador

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Tone Sigrell; [2018]
    Nyckelord :Safe water; Quantitative microbial risk assessment; QMRA; Sustainable water access; Water quality monitoring; kvantitativ mikrobiell riskanalys; QMRA; hållbar dricksvattenförsörjning; vattenkvalitétsövervakningsprogram;

    Sammanfattning : Globally a major health concern according to the World health organization (WHO, 2011) is gastro-intestinal infections caused by fecally contaminated water. The access to drinking water has increased due to international efforts, however the long-term sustainability and safety of the water accessed have gained criticism, and many water sources have proven to be both contaminated (UN, 2016) and badly managed (WHO, 2016a).

  5. 4. Multiple Substrate-Induced Respiration and Isothermal Calorimetry : Applicability in Risk Assessment of Contaminated Soil

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Caroline Wright; [2017]
    Nyckelord :Risk assessment; biological indicators; multiple substrate-induced respiration; MSIR; MicroRespTM; isothermal calorimetry; calorespirometric ratio; contamination; Cu; PAH; Riskbedömning; biologiska indikatorer; multipla substrat-inducerad respiration; MSIR; MicroRespTM; isotermisk kalorimetri; calorespirometric ratio; förorening; Cu; PAH;

    Sammanfattning : At present, soils face great threats. Consequences of human activities, such as climate change, acidification and contamination result in decreased soil health. This is a threat to human health and well-being, since our society is dependent on soil ecosystem services. LÄS MER

  7. 5. Bräddvattenstudie i Håbo kommun : Patogenspridning från lokalt reningsverk i recipient

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

    Författare :Tobias Johansson; [2015]
    Nyckelord :Overflow; waterborne outbreaks; wastewater; simulations; microbial contamination; Delft3D; MIKE–Urban.; Bräddvattenspridning; mikrobiell förorening; spridningssimulering; Delft3D; MIKE-Urban; SMHI; spillvattenledningsnät.;

    Sammanfattning : Klimatscenarier framtagna av SMHI visar bland annat på att nederbördsmängden kommer att öka i stora delar av Sverige. En ökad nederbördsmängd leder till att flöden i vattendrag och spillvattenledningar ökar, som i sin tur kan leda till att oönskade ämnen förorenar viktiga naturresurser så som dricksvattentäkter.
