  2. 1. On Uncertainty and Data Worth in Decision Analysis for Contaminated Land

    Author : Pär-Erik Back; Chalmers tekniska högskola; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; uncertainty; decision analysis; risk; sampling; data worth; soil sampling; contaminated land;

    Abstract : Contaminated soil and groundwater is a problem that has received increased attention in the last decade. Decision-making about investigation strategies, protective actions, and remedial actions is based on sparse and uncertain information, primarily data of contaminant concentrations and geological information.

  4. 2. Fractionation of Cu and Fe isotopes in metal-rich mine sites : biotic and abiotic processes

    Author : Nathalie Pérez Rodríguez; Magnus Land; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cu and Fe isotopes; fractionation; tailings; plants; phytoremediation; organic amendments; soil bacteria; Cu and Fe cycle; covellite; redox processes; Applied Geology; Tillämpad geologi;

    Abstract : After mineral exploitation the residual grinded and milled material, rich in sulphide minerals and heavy metals, is often left exposed to the atmospheric variables. This weathered mine waste material can lead to the formation of acid mine drainage (AMD) which has negative effects to the environment. READ MORE

  5. 3. Value of Information Analysis for Site Investigations in Remediation Projects

    Author : Pär-Erik Back; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; uncertainty; value of information; soil; decision analysis; sampling; remediation; contaminated land; site investigation;

    Abstract : Site investigations of contaminated land are associated with high costs. From a societal point of view, just enough economic resources should be spent to allow societys limited resources to be allocated optimally to sustainable development. READ MORE

  6. 4. Uncertainty, variability and environmental risk analysis

    Author : Monika Filipsson; Tomas Öberg; Bo Bergbäck; Lars Rosén; Linnéuniversitetet; []
    Keywords : Contaminated land; exposure assessment; exposure factors; risk analysis; risk perception; uncertainty; variability; probabilistic risk assessment; NATURAL SCIENCES; NATURVETENSKAP; Miljövetenskap; Environmental Science;

    Abstract : The negative effects of hazardous substances and possible measures that can be taken are evaluated in the environmental risk analysis process, consisting of risk assessment, risk communication and risk management. Uncertainty due to lack of knowledge and natural variability are always present in this process. READ MORE

  7. 5. Control of land use and groundwater quality in Colorado and Sweden

    Author : Hans Lönegren; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Land use; groundwater quality; organization; legislation; perspectives of the decision makers; plan; planning process; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : The aim of this research is to shed light upon the organization and the system of regulations adopted by modern, industrialized societies in the interactive fields of land use and groundwater. By studying groundwater, long-term perspectives become more clear. The following questions are examined.Are there adequate rules (e. READ MORE
