<p>This study is a degree project in environmental engineering at Mälardalens university. Its purpose has been to perform a risk assessment on whether or not any contaminations are present in the soil at two properties in Köping. The assessment was to be done accordingly to a method that has been set up by The Swedish Environmental Protection Agency (Naturvårdsverket). The method for investigation of contaminated sites is called MIFO. MIFO consists of two stages. In the first stage historical studies, a visit at the site, and studies of maps make up the basic data for the risk assessment. This study only contains the first stage of MIFO. The properties that have been examined are Maskinisten 6 and Valhall 2 in Köping. At Maskinisten 6 the present building was built in the 1970s. The buildings on Valhall 2 was built in the early 1940s as a part of an old mechanical industry named KMV. These properties are now rented by LEAX Mekaniska AB which also is a mechanical industry. LEAX produces mechanical components for industries and vehicles. In LEAX processes, oils, cutting fluids and washing fluids are the most commonly used chemicals. The assessments of possible pollutants toxicity, the pollution levels, the possibility of spreading, and possible exposure on humans and or the environment has led to different risk classes for the two properties. Maskinisten 6 has been classed in risk class 3. Valhall 2 has been classed in risk class 2. The difference is due to the historical differences. At Valhall 2, an assumption has been made that some dangerous, for the business common, chemicals has been used at some point and at some quantities. This assumption was made due to the fact that mechanical industry has been the main activity on the location for about 70 years. If evidence that these dangerous chemicals have not been used at all can be shown, the risk assessment may be revalued.</p>
