  2. 1. Ground Monitoring using Resistivity Measurements in Glaciated Terrains

    Author : Jaana Aaltonen; KTH; []
    Keywords : Resistivity; DIrect Current; Monitoring; Groundwater; Contaminant; Tracer Test; Geophysics;

    Abstract : The most common method of monitoring and mapping groundwatercontaminants is to extract and analyse a number of groundwatersamples from wells in the investigation area. However, thereare a number of limitations with this type of point-wiseinvestigation, as it is hard to acquire an adequate picture ofa heterogeneous and anisotropic subsurface using a fewpoints.

  4. 2. EstimatingChloride concentration in surface water and groundwater duet to deicing salt application

    Author : Eva-Lotta Thunqvist; KTH; []
    Keywords : road; deicing salt; monitoring; chloride; catchment area; river basin; simulation; GIS; groundwater; surface water;

    Abstract : A road in operation along with its traffic can pose aserious pollutant threat to groundwater and surface water inits vicinity. Examples of pollutants are metals from thecorrosion of vehicles, rails and poles and the wear of roadsurfaces and tyres; hydrocarbons from the wear of roadsurfaces, tyres, exhausts, oils; sodium chloride from roadsalt; and hazardous goods discharged in accidents.

  5. 3. 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

  6. 4. Chlorinated aliphatic hydrocarbons; an interdisciplinary study of degradation and distribution in complex environments

    Author : Sofia Åkesson; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Groundwater; Groundwater chemistry; Contamination; Chlorinated solvents; In situ remediation; Biodegradation; PCR; DCIP; CSIA;

    Abstract : In this thesis degradation of chlorinated solvents, e.g., tetrachloroethene (perchloroethylene [PCE]), has been examined, both natural occurring degradation and in situ remediation strategies. READ MORE

  7. 5. On the scope and assessment of pesticides in groundwater in Skåne, Sweden

    Author : Maria Åkesson; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; groundwater; pesticides; Sweden; Skåne; environmental tracers;

    Abstract : Pesticides are known to occur in groundwater worldwide. However, long-term pollution concerns and cause-effect relationships for specific regions remain limited. READ MORE
