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.

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.

During 40 years of industrial production, from the end of the 1890?s until the end of 1930?s, coal and wood distillation products were manufactured in AB Carbo?s tar factory along the River Gimån in Grötingen, in the county of Jämtland, Sweden. In accordance with the Swedish Environmental Protection Agency?s Methods for Inventories of Contaminated sites, MIFO, the site in Grötingen has been identified as a potentially Contaminated site. In order to determine whether toxic substances pose a threat to human health and ecological systems in the area, there was a need to investigate the presence of contaminants, their levels and potential for migration.

Risk assessment of effects on the environment and health outcome caused by the iron industryLina LöfqvistIn Sweden you can find lots of contaminated areas, which can create problems for both humans and nature. To reduce the long-term contamination grades, Naturvårdsverket have created a report with regard to the Contaminated sites. This builds on the ?Method for Inventories of Contaminated sites? which is abbreviated MIFO. The aim of MIFO is to achieve better environmental planning in Sweden.

The county administration asked LKAB to make an inventory of possibly Contaminated sites caused by their mining activity. The inventory should be performed according to the MIFO model, a method from SEPA which is used to assess a Contaminated site. The first phase involves collection of information through interviews and site inspections and in phase 2 a general survey with field sampling is conducted. LKAB started the work with the first phase of the survey during 2003. During this project the information collected in Phase 1 was evaluated and 16 of the sites were chosen to proceed to MIFO Phase 2 (six sites in Kiruna, and 5 sites respectively in Svappavaara and Malmberget). The sampling of these 16 sites was performed during week 27 2004.

This paper describes the redesign of a site (Kolonn.se). Some of the problems with the site were a lack of structure and a design that was unclear both visitor and search engines. The site now has a new design and structure that has been taking form in Axure prototypes that has been tested and applied into WordPress. The results are a site with a new main menu, new graphic profile and logo. Also SEO-adapted content such as correctly structured headers, meta tags, descriptions and key words that has been implemented in the content.

The aim of this paper was to study fourteen pottery sherds found at the site of Ayia Irini in northern Cyprus using Gas chromatography- Mass spectrometry. Ayia Irini has by the archaeologists of the Swedish Cyprus Expedition been interpreted as a sanctuary, with activity spanning from the Late Bronze Age throughout the Cypriot Iron Age.The results showed traces of vegetable lipids in almost all samples, and traces of lipids from terrestrial animals in all but two. One sample showed traces of resin. Several samples were contaminated by different components found in plastics, such as plasticizers. No obvious common denominators were found for samples of similar pottery type or similar dating.

What on earth do people see in camping? Why do they choose this compact living in their holiday? All that people in caravans who are put together in a camp site.The purpose of my study was to find out who and wy. My ethnographic study in a camp site with participation observations, interviews and analysis have results in facts that show why.The most common camper is the house owner with average income. And the choice of the camp site depend on the security and the service that the camp site offered. The camp site was controlled and the campers controlled each other.

In urban planning and design today interventions tend to take place in already existing areas and inevitably effect also surrounding areas. The many parties involved in any change leads to a demand for a shared language around these areas. This thesis aim to, through understanding and communicating a site, Stora Södergatan in Lund Sweden, inspire to a novel way of looking at an urban site preceding design- or planning interventions. Based on a theoretical framework where site is considered as a relational construct, material as well as immaterial, a framework for site thinking is constructed. Further, with theory of representation, the communication of the site is emphasized and accounted for as part of the framework.

Using leaching test is a way to get a picture of pollutants retention and leaching in a risk assessment on contaminated land. There are several different types of standardised leaching tests today, where the natural leaching processes are speeded up to make it possible to predict the leaching of pollutants. These leaching tests have been developed for waste and there are no specific guidelines on how to judge the results from the tests, when making a risk assessment on contaminated land. This work is an investigation on how to use leaching test in this type of risk assessments. The strengths and weaknesses of the different types of tests are discussed. Depending on what type of information you want from your leaching test, different types of tests are suitable.

This thesis was commissioned by Tekniska verken, Energy Division with the overall aim to investigate the concept of environmental debt and what it means for a business. Furthermore, a sustainable risk and responsibility investigation shall be carried out on the concerned areas. Finally, the priority areas shall be highlighted and proposed actions presented. The Swedish Environmental debt concept was presented in 1992 by Arne Jarnelöv. Environmental debt is defined as restoration costs for environmental damage. In the early days the concept did not take into account who was responsible, but the environmental debts was regarded as a humanity debt to future generations.

Risk assessment is made to determine risks with contaminated areas and to determine which treatment the area requires. In Sweden, risk assessment is divided into three levels: risk analysis, facilitated risk assessment and detailed risk assessment. In detailed risk assessment site-specific guideline values are developed to compare with values of contaminants that are measured in the area.Site-specific guideline values vary with geological and hydrogeological parameters. The purpose of this report is to examine which of these parameters that affect the guideline values. The examination was done using a calculating program for consideration from the Swedish Environmental Protection Agency from the year of 1997.

This report is written in cooperation with Skanska Sverige Hus Väst and it is discussing the role of site managers within the company. The report will bring up the demands that is put upon site managers and will also discuss stress related problems and how to change and develop the role as a site manager.We came up with three conclusions in this report. We believe that Skanska could develop VSAA to make it easier to use for site managers. We also believe that a further development of the project engineer is of great value, to give him or her greater responsibilities. The last conclusion is to change the responsibilities between the site manager and the production manager, to give the production manager a greater responsibility in the production..

This thesis is a case study of the search function on the University of Uppsala?s web site. The search function in this study was chosen since it exists on a large and complex web site and there were apparent lacks in the old version of the search function. The thesis highlights some of the problems that can appear in the development of a search function on a local site. One interesting find is that one of the most difficult issues is organizational and not technical.
