… a consequence of the high density and long duration of industrial activities metals, cyanide, trichloroethene, oil and solvents are likely pollutants. Most of the industries have earlier used the nearby streams as recipients without any treatment of the polluted waste water. A …
… collected as well. The water and soil samples were analyzed with regard to metals, organic compounds and nutrients. Furthermore, groundwater flow has been modeled using VS2DI, in order to get a picture of the groundwater’s flow direction and velocity under the landfill. In the …
… were done on the blast-furnace residues and a very small amount of hazardous metals were leached out. These areas were classified in risk class 3, moderate risk for human health and the environment. No further surveys are therefore necessary. Rockwool was based in Gimo during …
