The aim with my master thesis is to develop and test the applicability of methods to quantify and map solute advective travel times and pollutant transport at the catchment scale. Such quantification and mapping can increase the understanding of catchment-scale pollutant transport in general and contribute to the identification of the main sources of water pollution and the most efficient measures to reduce such pollution. The study area is the catchment of Oxundaån, about 20 km north of Stockholm. For detailed GIS modeling of water flow and catchment-scale Contaminant transport in water, I´ve used new high-resolution elevation maps, land cover maps and soil maps combined with other available relevant data..

Over an extended period of time there have been plans to establish a shared facility in Lennheden to extract groundwater from the Badelunda esker to provide drinking water for the cities of Borlänge and Falun. The city of Falun is dissatisfied with the quality of its drinking water and the city of Borlänge is concerned about the risk of contamination of its existing groundwater supply at its current location. To provide a basis for a decision on this issue, the company Midvatten AB has been commissioned to perform hydrogeological investigations in the area of Lennheden.The purpose of this thesis is to design a functional groundwater model of the area between Lennheden, place of planned extraction, and Övre Tjärna, place of existing extraction, to get a better understanding of the groundwater situation in the area. A groundwater model enables simulations of different scenarios in risk assessment and Contaminant transport. The aim of the thesis is that the model can be used as an aid in Midvatten?s investigations in Lennheden and that it also can be used in future projects in the area.The model has been made in Processing Modflow 5.3 and encompasses an area of 19,5 × 11 km along the Badelunda esker and the river Dalälven between Djurmo and Frostbrunnsdalen.

AbstractThe research project Liberation, supported by the European Commission under the Environment and Sustainable Development Programme (Fifth RTD Framework Programme) aimed at developing a decision support system for ecological risk assessment of contaminated sites has proposed a tiered system including the triad method. This method integrates contaminant chemistry and bioavailability analyses with observed ecotoxicological effects in soil and groundwater. In this study the triad method was used to perform a risk characterization of a former surface treatment and metal industry, now used for the student union buildings of the Mälardalen University in Eskilstuna, Sweden. On the site, high concentrations of copper, zinc and nickel have been detected in the soil in a preliminary investigation of contaminant levels with XRF. For performing the risk assessment of the site according to the triad method, contaminant bioavailability, soil metal concentrations and soil toxicity were determined and an ecological assessment was carried out on four selected soil samples (one reference soil and three samples with low (B), medium (C) and high (D) contaminant levels). Contaminant bioavailability was measured through leaching (ISO TC 190/S7) and biouptake tests (DGT).

This thesis compares different methods for risk assessment of a creosote contaminated site in Vansbro, Dalarna. In a complementary study the importance of using representative data for calibration and validation of stationary groundwater models is discussed. The time dependency between surface water levels and groundwater levels on the site in Vansbro is evaluated by step response analysis. The results show that the groundwater levels reflect only long-term variation in the surface water levels. Hence the use of such long-term means for calibration and validation of the stationary groundwater models is the only theoretically defendable alternative.As a first step in the comparison of risk assessment methods the degree of contamination is evaluated on the basis of generic guideline values for contaminated soils, developed by the Swedish Environmental Protection Agency.

Certain types of waste, e.g. bottom ash originating from municipal solid waste incineration (MSWI bottom ash) can be used as road construction materials. A potential problem is the possibility of substances leaching out of the road and spreading in the surrounding groundwater.The aim of this master?s thesis is to conclude whether hydrogeological type settings can be employed to, based on local conditions, provide an estimate of the probable spreading of these substances in the surrounding groundwater, and whether certain types of soils can be identified as being less suitable for the localization of a MSWI bottom ash road. A hydrogeological type setting is defined as a mappable unit with similar hydrogeological properties.

För att kunna skapa intressanta och engagerande berättelser i spel behövs förståelse för hur spels unika egenskaper påverkar berättande. Ett spelnarrativa kan delas upp i det inbäddade narrativet, som består av till exempel texter och dialog, samt det emergenta narrativet, som uppstår ur spelets gameplay. När dessa två delar inte stämmer överens uppstår ludonarrativ dissonans. I detta arbete undersöks hur ludonarrativ dissonans påverkar narrativ transport, det vill säga inlevelse i en berättelse. Två versioner av ett berättelsedrivet spel skapades med olika mekanikerna för att uppnå låg respektive hög ludonarrativ dissonans.

Each year 225 million pigs are transported within the European Union (EU) for slaughter, fattening and breeding. This results in poor animal welfare due to the fact that animals are exposed to several numbers of stress factors in the vehicle during loading, transit and unloading. Animal welfare can be defined as how well the animal attempts to cope with its environment and during transport there is often severe difficulty for the pigs to cope properly. There is a growing societal concern for animal welfare. This resulted in that the European Union enacted a law called the EU-regulation with certain directives of how to improve the welfare of the animals during transport.

The transport sector is one of the biggest pollutants in the European Union. In relation to transport policies and environmental policies, intermodal transportation solutions are of high relevance to establish a sustainable transport sector for the future. Intermodality which is defined as smooth transition between transport modes is a key figure for how modal shares are divided between the modes of transportation. The aim of this bachelor?s thesis is to examine the research gap whether policies intended for a specific transport mode affects each other in relation to EU policies intended for intermodality.

Chlorinated solvents are common contaminants in soil and water. Under anaerobic conditions microbes are capable of transforming chlorinated solvents into ethylene which would result in a remediation of the contaminated area. In order to use natural attenuation as a remediation method evidence of continuous degradation is required. Furthermore, the degradation must occur at a sufficient rate and continuous monitoring of the site is needed until the demanded levels are achieved. A field study was performed on the basis of data from a dry-cleaning facility contaminated mainly by perchloroethylene.

On the first of January 2012, a new public authority was formed in Värmland, due to a new legislation on public transport. The first task for the new public authority was to produce a plan for the development of public transport. In order to do so, it had to execute an extensive consultation process about the long-term goals of public transport. The purpose of the thesis is to investigate how a public authority can use a consultation process as a means to clarify accountability and produce unified goals. To answer that, I have done a case study about how the new regional public authority in Värmland for public transport has acted in the process of writing a plan for the development of public transport.

There are two groups of haulage contractors in roundwood transport , those who are contracted direct by the transport buyer and those who are connected to a freight company which in its turn is contracted by the transport buyer. Today the roundwood haulage is dominated by contractors with one to two lorries. The effort of coordinating transportation for a transport buyer is dependent on how many communication contacts that must be managed (how many individual haulage contractors the transport buyer has to work with). A structural change in the sector that leads to a decrease in the number of haulage contractors but an increase in the capacity of each contractor, makes it possible for a transport buyer to coordinate transports with fewer communication contacts. The reason why a company reaches a certain size can be explained by the number of contracts it makes and manages.

I Sverige sker cirka 2500 transporter av nyfödda barn varje år. Socialstyrelsen publicerade i slutet av år 2013 en ny vägledning ?Vård av extremt tidigt födda barn?. Ett av de områden som har prioriterats är neonatala transporter. Betydelsen av en väl fungerande transportorganisation är nödvändig för att skapa en säker och jämlik vård för denna patientgrupp.

Syftet med denna uppsats var att undersöka vilka faktorer som påverkar hur förvärvsarbetande människor i Gävle använder sig av bil och aktiv transport när de transporterar sig till destinationer inom staden. Tio personer, fem butiksbiträden och fem lärare, intervjuades angående deras transportvanor och resonemang kring valet av transportsätt.Resultatet visade att aktiv transport var det vanligaste transportsättet till arbete, träning och butiker i centrum medan bilen var det vanligaste transportsättet till mataffären och destinationer på längre avstånd från hemmet. Avståndet till destinationen, tiden det tar att transportera sig, transport av eventuella varor, bekvämlighet, intresse av motion och rekreation, årstid, väder samt synen på ekonomi och miljö var faktorer som påverkade om deltagarna valde att transportera sig med bil eller aktiv transport. Definitionen på de olika faktorerna varierade mellan deltagarna, vilket kan tyda på att det är den personliga uppfattningen om de olika faktorerna som avgör vilket transportsätt som väljs. Det framkom ingen märkbar skillnad i resvanor mellan deltagare med olika utbildning och arbete..

It is estimated that 22 000 contaminated areas exist in Sweden today. In order to classify the risk of contaminant migration from these areas and to prioritize which of these contaminated areas should first be treated, the Swedish Environmental Protection Agency (EPA) has designed a method, for the investigation of contaminated areas (MIFO). One of these contaminated areas is the landfill Gräsötippen outside Köping. The landfill has been used by both Yara AB and the Köping municipality between the years 1945 and 1975, and both industrial and household waste have been deposited there. The aim of this report is to survey which contaminants that can be found in the soil and water in the landfill Gräsötippen and to evaluate the migration of these contaminants.
