  2. 1. Targeted and untargeted analysis of organic contaminants from on-site sewage treatment facilities : Removal, fate and environmental impact

    Author : Kristin Blum; Peter Haglund; Patrik Andersson; Pim Leonards; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; decentralized sewage treatment; wastewater; surface water; environmental fate; bioavailability; removal efficiency; mass fluxes; biochar; environment; GC×GC-MS; LC-IM-MS; mass spectrometry; contaminants; pollutants; prioritization; non-target analysis; screening; analytisk kemi; Analytical Chemistry;

    Abstract : On-site sewage treatment facilities (OSSFs) are widely used all over the world to treat wastewater when large-scale sewage treatment plants (STPs) are not economically feasible. Although there is great awareness that the release of untreated wastewater into the environment can lead to water-related diseases and eutrophication, little is known about organic contaminants and their removal by OSSFs, environmental load and fate.

  4. 2. REACTIVE TRANSPORT MODELLING OF DISSOLVED CO2 IN POROUS MEDIA : Injection into and leakage from geological reservoirs

    Author : Nawaz Ahmad; Anders Wörman; Auli Niemi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 geological storage and safety; leakage of brine saturated with dissolved CO2; reactive transport; fracture; advection; dispersion and diffusion; sorption; carbonate minerals kinetic reactions; calcite; dolomite; siderite; porosity; permeability; heat transport; Land and Water Resources Engineering; Mark- och vattenteknik;

    Abstract : The geological sequestration of carbon dioxide (CO2) is one of the options of controlling the greenhouse gas emissions. However, leakage of CO2 from the storage reservoir is a risk associated with geological sequestration. Over longer times, large-scale groundwater motion may cause leakage of dissolved CO2 (CO2aq).

  5. 3. Virus Fate and Transport in Groundwater : Organic matter, uncertainty, and cold climate

    Author : Jean-Marc Mayotte; Keven Bishop; Stephan Köhler; Fritjof Fagerlund; Sven Halldin; Constantinos V. Chrysikopoulos; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; managed aquifer recharge; organic matter; virus; numerical modeling; uncertainty; Hydrology; Hydrologi; Mikrobiologi; Microbiology;

    Abstract : Water managers must balance the need for clean and safe drinking water with ever-increasing amounts of waste-water. A technique for treating and storing surface water called “managed aquifer recharge” (MAR) is frequently used to help maintain this balance. READ MORE

  6. 4. Monitoring transport and fate of de-icing salt in the roadside environment : Modelling and field measurements

    Author : Annika Lundmark; Per-Erik Jansson; Bo Olofsson; Ann-Catrine Norrström; Helen K. French; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chloride; De-icing salt; Groundwater; Modelling; Monitoring; Road; Roadside; Soil water; Water in nature and society; Vatten i natur och samhälle;

    Abstract : Roads and traffic are a major non-point source of pollutants and may have severe impacts on surface water, groundwater, soil and vegetation. In cold climates, de-icing salt is one such pollutant that may cause increased chloride concentrations and induce other effects on the environment. READ MORE

  7. 5. In the Pipe or End of Pipe? : Transport and Dispersion of Water-borne Pollutants and Feasibility of Abatement Measures

    Author : Christoffer Carstens; Vladimir Cvetkovic; Auli Niemi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Contaminant transport modelling; Groundwater; Dispersion; Wave power; Eutrophication;

    Abstract : Eutrophication is one of the key environmental problems of today, both in terms of complexity and magnitude. For the Baltic Sea (BS), eutrophication is an acute problem, leading to hypoxic conditions at the bottom; a situation that is sustained and amplified, when phosphorus is released from hypoxic sediments.
