    Improved geochemical modeling of lead solubility in contaminated soils by considering colloidal fractions and solid phase EXAFS speciation2018In: Applied Geochemistry, ISSN 0883-2927, E-ISSN 1872-9134, Vol. 92, p. 110-120Article in journal (Refereed)
    Abstract [en]

    Lead (Pb) is a common contaminant in soils at e.g. mining, shooting range, and glassworks sites. In order to make reliable risk assessments and appropriate decisions on various "gentle remediation options", such as applying phosphate, compost, or zero-valent iron to soils, the binding mechanism of Pb and its speciation needs to be known. Multi-surface geochemical equilibrium models are useful tools for estimating trace metal solubility and speciation, but for Pb the predictions are often poor. This study evaluates the recent parameterization for Pb in the Visual MINTEQ code for its ability to predict the solubility of Pb at different pH values in four historically contaminated Swedish soils. As an independent validation of the model performance, the modeled solid-phase speciation was compared to measured Pb speciation retrieved using extended X-ray absorption fine structure (EXAFS) spectroscopy.

    Current and future role of instrumentation and monitoring in the performance of transport infrastructure slopes2017In: Quarterly journal of engineering geology and hydrogeology, ISSN 1470-9236, E-ISSN 2041-4803, Vol. 50, p. 271-286Article in journal (Refereed)
    Abstract [en]

    Instrumentation is often used to monitor the performance of engineered infrastructure slopes. This paper looks at the current role of instrumentation and monitoring, including the reasons for monitoring infrastructure slopes, the instrumentation typically installed and parameters measured. The paper then investigates recent developments in technology and considers how these may change the way that monitoring is used in the future, and tries to summarize the barriers and challenges to greater use of instrumentation in slope engineering. The challenges relate to economics of instrumentation within a wider risk management system, a better understanding of the way in which slopes perform and/or lose performance, and the complexities of managing and making decisions from greater quantities of data.

    Evaluation of frameworks for ecotoxicological hazard classification of waste2016In: Waste Management, ISSN 0956-053X, E-ISSN 1879-2456, Vol. 58, p. 14-24Article in journal (Refereed)
    Abstract [en]

    A new harmonized EU regulation for the classification of waste came into effect on 1st June 2015, in which the criteria and assessment methods for the classification of hazardous waste are harmonized with other internationally agreed-upon systems for hazard classification of chemicals (CLP). However, criteria and guidance for the assessment of ecotoxicological hazard (Hazard Property 14, HP14) are still lacking for waste classification. This paper have evaluated and compared two HP14 classification frameworks: (i) a calculation method (summation) for mixtures, and (ii) leaching tests. The two frameworks were evaluated by surveying and evaluating ecotoxicological data for Cu, Zn, K and Ca species in bottom ash from incinerated waste, together with geochemical speciation modelling. Classification based on the summation method proved to be highly sensitive to the choice of speciation and ecotoxicological classification. This results in a wide range of critical concentrations triggering hazardous classification (in particular for Cu and Zn). Important parameters governing the availability of toxic elements, such as transformation from one species to another and complexation on organic or inorganic sorbents, are not accounted for. Geochemical modelling revealed that a testing strategy built on CLP based leaching tests (liquid/solid ratio (L/S) 10,000, pH range 5.5-8.5) avoids bias and is superior to the summation method with respect to both precision and accuracy. A testing strategy built on leaching tests, designed for risk assessment purposes, (L/S ratio of 10, natural pH of the ash) severely underestimate the hazard associated with the presence of toxic compounds (Cu and Zn), while simultaneously falsely indicate a hazardousness due to the presence of non-toxic compounds (Ca and K). However, the testing methods adopted by CLP are problematic from a practical and functional point of view. To conclude, the L/S ratio and pH were found to be critical for hazard classification based on leaching test methods. Further studies are needed to develop a relevant, practical and functional testing strategy for HP14 hazardous waste classification.

    Biofuel or excavation? - Life cycle assessment (LCA) of soil remediation options2011In: Biomass and Bioenergy, ISSN 0961-9534, E-ISSN 1873-2909, Vol. 35, no 2, p. 969-981Article in journal (Refereed)
    Abstract [en]

    The environmental consequences of soil remediation through biofuel or through dig and dump were compared using life cycle assessment (LCA). Willow (Salix viminalis) was actually grown in situ on a discontinued oil depot, as a phytoremediation treatment. These data were used for the biofuel remediation, while excavation and refill data were estimated from experience. The biofuel remediation had great environmental advantages compared to the ex situ excavation remediation. With the ReCiPe impact assessment method, which included biodiversity, the net environmental effect was even positive, in spite of the fact that the wood harvest was not utilised for biofuel production, but left on the contaminated site. Impact from the Salix viminalis cultivation was mainly tbrough land use for the short rotation coppice, and through journeys of control personnel. The latter may be reduced when familiarity with biofuel as a soil treatment method increases. The excavation and refill remediation was dominated by the landfill and the transport of contaminated soil and backfill.

    Biogrouting compared to jet grouting: Environmental (LCA) and economical assessment2009In: Journal of Environmental Science and Health. Part A: Toxic/Hazardous Substances and Environmental Engineering, ISSN 1093-4529, E-ISSN 1532-4117, Vol. 44, no 4, p. 346-353Article in journal (Refereed)
    Abstract [en]

    In order to predict consequences of replacing jet grouting with biogrouting, and identify major contributors to the cost of both technologies, a large road project in Stockholm, Sweden, was used as a case study. Jet grouting had been used to seal the contact between sheet piling and bedrock, biogrouting for the same function was computed. A comparative environmental and economical assessment was carried out using life cycle assessment (LCA). The results show that biogrouting was cheaper than jet grouting and would have had lower environmental impact The major difference was the transport and use of heavier equipment for jet grouting. Biogrouting also used less water and produced less landfilled waste. However, the production of urea and CaCk for biogrouting required much energy.

    Reuse and recycle - Considering the soil below constructions2014In: Science of the Total Environment, ISSN 0048-9697, E-ISSN 1879-1026, Vol. 485-486, p. 792-797Article in journal (Refereed)
    Abstract [en]

    The European Construction Products Regulation provides a life cycle based framework for the environmental assessment of construction products. Harmonised European standards for the assessment of the release of dangerous substances and for declaration of environmental performance are in progress. Risk based limit values for the protection of soil and groundwater below construction works will still bet set nationally. In this paper we review the possibilities to expand the ongoing harmonisation to include risk assessment and life cycle assessment (LCA). Based on reviews of national European limit value models (LMVs) for assessment of release to soil and groundwater, two areas for harmonisation emerge: (1) The toxicological criteria. Toxicological endpoints to protect human health and environment are similar, and data from the same toxicological data sets are used to establish acceptance criteria. (2)The emission part of LMVs. We extracted six generic construction works for granular materials. These encompass the most common choices and span the different release scenarios applied.

    Kostnadsnyttoanalys för förebyggande åtgärder mot skred och ras2010In: Samhällsbyggaren, ISSN 2000-2408, no 4, p. 34-39Article in journal (Other academic)
    Abstract [sv]

    För att beräkna skredrisk måste skredsannolikheten och skredkonsekvenserna vägas samman. I tre fallstudier har kostnadsnyttoanalys genomförts för utförande av preventiva åtgärder mot jordskred för olika bebyggda slänter mot vattendrag i Sverige med hänsyn av klimatförändringens inverkan. Metoden bedöms kunna tillämpas vid stabilitetsutredningar så att faktorerna klimatförändring, skredsannolikhet och skredkonsekvenser belyses, som sedan vägs mot åtgärdskostnader samt den reducerade sannolikheten för skred efter dessa åtgärder.

    Organic matter in Swedish clays and its importance for quick clay formation1974Report (Other academic)
    Abstract [en]

    This report deals wlth the importance of, primarily, organic matter in Swedish quick clays. Particularly, the relationship between dispersing agents and sensitivity has been investigated. A study of a great number of reports in the SGI files showed that varved, fresh-water sedimented quick clays are relatively common in Sweden. The adsorbed double layer as well as the Donnan effect and the chemical equilibrium between double layer composition and pore water composition is discussed. The possibility that organic matter can form a fissured structure in the clay is also treated. Methods have been developed to isolate dispersing agents from Swedish clays and attempts made to analyse these agents. It is found that it is easy to isolate dispersing substances but very difficult to find substances with a known composition. Especially the humic acids are impossible to analyse at present. One group of dispersing substances which can be isolated, purified and chromatographed is the soaps. These are occurring in series of both saturated and unsaturated fatty acids. Another group that can be detected comprises the ten sides. It has also been shown that dispersing agents isolated from quick clay can originate from impurities infiltrated in the ground.

    Salt in Swedish clays and its importance for quick clay formation. Results from some field and laboratory studies1969Report (Other academic)
    Abstract [en]

    This report deals mainly with the importance of salt in Swedish clays. Especially the relationship between salt and sensitivity has been investigated. Methods have been developed by which the salt content in Swedish clays can be determined rapidly. A special instrument, "the salt sounding tool", has been used in the field to determine the approximate salt content in a clay. Rapid chromatographic methods have been developed and used to study the ionic composition of the pore water in clays. The salt conditions in clays from different parts of Sweden are discussed. It has not been possible to correlate the sensitivity of Swedish clays with the total salt content. There exists, however, a correlation between the ionic composition of the pore water of a clay and the sensitivity. Quick clays have an ionic composition which is not in accordance with the simple Donnan effect condition due to the presence of organic material in the clay. The investigation also shows that the strength properties of extracted samples of quick clay change with time. A method has been developed to detect slip surfaces in slides from salt soundings. The report also includes a study of the diffusion processes in clays as well as a laboratory investigation of the leaching processes.

    Cost-benefit analysis as a part of sustainability assessment of remediation alternatives for contaminated land2015In: Journal of Environmental Management, ISSN 0301-4797, E-ISSN 1095-8630, Vol. 157, p. 267-278Article in journal (Refereed)
    Abstract [en]

    There is an increasing demand amongst decision-makers and stakeholders for identifying sustainable remediation alternatives at contaminated sites, taking into account that remediation typically results in both positive and negative consequences. Multi-criteria analysis (MCA) is increasingly used for sustainability appraisal, and the Excel-based MCA tool Sustainable Choice Of REmediation (SCORE) has been developed to provide a relevant and transparent assessment of the sustainability of remediation alternatives relative to a reference alternative, considering key criteria in the economic, environmental and social sustainability domains, and taking uncertainty into explicit account through simulation. The focus of this paper is the use of cost-benefit analysis (CBA) as a part of SCORE for assessing the economic sustainability of remediation alternatives. An economic model is used for deriving a cost-benefit rule, which in turn motivates cost and benefit items in a CBA of remediation alternatives. The empirical part of the paper is a CBA application on remediation alternatives for the Hexion site, a former chemical industry area close to the city of G€oteborg in SW Sweden. The impact of uncertainties in and correlations across benefit and cost items on CBA results is illustrated. For the Hexion site, the traditional excavation-anddisposal remediation alternative had the lowest expected net present value, which illustrates the importance of also considering other alternatives before deciding upon how a remediation should be carried out.

    Evaluating solubility of Zn, Pb, Cu and Cd in pyrite cinder using leaching tests and geochemical modelling2017In: Applied Geochemistry, ISSN 0883-2927, E-ISSN 1872-9134, Vol. 85, p. 106-117Article in journal (Refereed)
    Abstract [en]

    Production of sulfuric acid by roasting of pyrite (Fe sulfide) produces a Fe rich waste product, pyrite cinder (or pyrite ash), which often contains high levels of trace metals such as Zn and Pb. The chemical forms of the metals and their solubility in these materials are poorly known. To evaluate the risks associated with pyrite cinder and manage cinder contaminated sites efficiently more knowledge on the chemical processes in pyrite cinder is needed. In this study the solubility of Zn, Pb, Cu and Cd in a pyrite cinder from Bergvik, Sweden, was investigated. The objectives were to (i) identify the solubility controlling processes for Zn, Pb, Cu, and Cd in the pH range 3-9, (ii) characterize the Fe (hydr)oxides present in these materials and (iii) to identify implications for management strategies of pyrite cinder contaminated sites. This was done using a combination of batch experiments, selective extractions, X-ray absorption spectroscopy and geochemical modelling. Hematite was identified as the dominating Fe mineral in the cinder. A geochemical model using generic binding parameters could describe the solubility of Zn, Cu and Cd in the cinder well, while Pb concentrations were generally underestimated. The modelling indicated that adsorption to Fe (hydr)oxides was the most important solubility controlling mechanism for all metals, except for Zn at pH greater than 6, where Zn minerals seemed to control the concentrations of Zn. To minimize leaching of Zn, Pb, Cu and Cd from cinder materials, remediation strategies should be focused on keeping the pH greater than 6.

    Klimatförändringar ökar skredriskerna i Göta älvdalen2012In: Samhällsbyggaren, ISSN 2000-2408, no 4, p. 19-23Article in journal (Other academic)
    Abstract [sv]

    Under tre år, 2009-2011, har Statens geotekniska institut, SGI, utfört en skredriskkartering av Göta älvdalen. Dalen, som sträcker sig mellan Vänern och Göteborg, är en av de mest skredfrekventa dalgångarna i Sverige. Resultaten från utredningen visar att flera områden har en hög skredrisk för dagens förhållanden samt att en ökad nederbörd, orsakad av framtida klimatförändringar, i flera områden ökar skredrisken. Åtgärder för flera miljarder kronor är nödvändiga för att säkerställa stabiliteten längs älven.

    Resilience to natural hazards An analysis of territorial governance in the Nordic countries2018In: International Journal of Disaster Risk Reduction, E-ISSN 2212-4209, Vol. 31, p. 1283-1293Article in journal (Refereed)
    Abstract [en]

    Institutional arrangements at work in the governance of natural hazard risks in Denmark, Finland, Iceland, Norway and Sweden are reviewed and analyzed against the territorial governance conceptual framework. The review and analysis are based on information gathered through literature, an expert online survey, interviews and a one and a half-day workshop. The Nordic countries share certain governance characteristics, such as a welfare state legacy, promotion of transparency, and the inclination to bottom-up and polycentric governance approaches. In this context, it is no surprise that seemingly the institutional arrangements for natural hazard management are formed along similar lines. However, the hazard landscape is diverse and legislation and acquired governance practices in each country reflect these differences, particularly in the production of knowledge about the hazards. Nordic governance regimes and regulations combine broadly defined responsibilities with detailed requirements and distributed authority across sectors. Yet, a closer look at some of the territorial preconditions reveals some interesting differences that influence DRM and societal resilience.

    Erfarenheter av byggmetoder på torvmark2016Report (Other academic)
    Abstract [sv]

    Huvudsyftet med projektet var att genomföra en litteraturstudie för att sammanställa och analysera tidigare, huvudsakligen under de senaste cirka 15 åren avslutade projekt, nationella och internationella erfarenheter av byggande på torvmark i samband med väg- och järnvägsprojekt. Målet var att sammanställa nationella och internationella erfarenheter från byggmetoder på torvmark i en state-of-the-art rapport. En inventering av avslutade och pågående nationella projekt har utförts för erfarenhetsåterföring. Från projekten har sammanfattats, så långt som information funnits tillgänglig, för använd byggmetod: undersökningar, dimensionering och design, uppföljningar i byggskedet och allmän erfarenhetsåterföring. Speciellt har goda exempel på byggmetoder lyfts fram. Projektet avhandlar byggande på "torvmark" och således även jordprofiler där torv ingår tillsammans med andra jordmaterial, men med materialet torv i fokus.

    Erfarenheter av byggmetoder på torvmark2017In: Bygg & Teknik, ISSN 0281-658X, Vol. 109, no 1, p. 42-44Article in journal (Other academic)
    Abstract [sv]

    Det finns byggmetoder som används och fungerar väl för såväl nybyggnation som förstärkning av vägar och järnvägar på torvmark. I en ny publikation 2016 vid Statens geotekniska institut, SGI, presenteras exempel på goda erfarenheter av olika byggmetoder och ges praktiska rekommendationer avseende dessa. Men de beräkningsmetoder och beräkningsmodeller som används för att dimensionera åtgärder i torvmark bygger huvudsakligen på sådana som utvecklats för finkornig mineraljord och inte fiberrik torv. Med nya kunskaper i framtiden avseende egenskaper, metoder och modeller för torv finns stora möjligheter att kunna effektivisera valet av byggmetod och tillhörande dimensionering.

    Sättningar i sulfidjord - undersökningar, fältmätningar och beräkningar2018In: Bygg & Teknik, ISSN 0281-658X, Vol. 110, no 1, p. 60-62, 64 - 66Article in journal (Other academic)
    Abstract [sv]

    Bygg- och anläggningsbranschen behöver verktyg för att kunna prognostisera sättningar inklusive långtidssättningar i sulfidjord med rimlig tillförlitlighet. Uppkomna verkliga sättningar orsakade av en anläggning avviker ofta (väsentligt) från de på förhand förväntade, och som regel fås större men ibland också mindre sättningar. Långtidsdeformationer (krypning) kan pågå i decennier och långtidssättningar kan bli avsevärda och leda till skador hos konstruktioner som vägar, järnvägar och konstbyggnader. I denna artikel ges praktiska rekommendationer avseende sättningar som gäller allmänt för svenska finkorniga jordar.

    Photographic feature: Monitoring of negative porewater pressure in silt slopes2017In: Quarterly journal of engineering geology and hydrogeology, ISSN 1470-9236, E-ISSN 2041-4803, Vol. 50, p. 245-248Article in journal (Refereed)
    Abstract [en]

    In the northern part of Sweden there are several natural silt slopes adjacent to local roads or highways. These slopes may have a height of 40?-?50 m and an average inclination close to the friction angle of the material (Fig. 1). One reason that these slopes relatively seldom fail is related to negative porewater pressures (suctions). As knowledge on the size and seasonal variations of negative porewater pressures is limited in Sweden, as well as internationally, conservative values of these pressures have been used in stability calculations. To enhance our knowledge of porewater pressure distribution and its seasonal variations, an investigation was carried out in two selected slopes with the main focus on long-term monitoring of negative porewater pressures (suctions) in slopes related to their stability. The overall aims of the project were to increase the knowledge of seasonal variations of negative porewater pressures, to develop an improved method for field and laboratory testing of silt, and to form the basis for more reliable stability calculations.

    Effektivare markbyggande och FoU för ett hållbart samhälle2016In: Bygg & Teknik, ISSN 0281-658X, Vol. 108, no 1, p. 24-26Article in journal (Other academic)
    Abstract [sv]

    Forskning och utveckling (FoU) inom markbyggande innebär möjligheter till stor ekonomisk besparingspotential och möjligheter till miljömässigt bättre lösningar vid byggande och underhåll. I relation till de mycket omfattande samhällsatsningarna och till de stora värdern som står på spel satsas det relativt lite medel på forskning och utveckling inom markbyggande i Sverige. I denna artikel vill vi peka på några områden där forskning och utveckling behövs och kan bidra till ökad kvalitet och effektivitet i markbyggandet.
