The purpose of this study was to determinate what requirements there should be on refilling material used as soil remediation based on the soil environment, i.e. soil processes and factors important to soil-dwelling organisms. The study was conducted by investigating which parameters that is important for the soil environment and by comparing them with each other. To exemplify how the parameters may change in different locations, data for total organic carbon, dry matter (i.e. water content), and pH were analyzed from different locations before and after soil remediation. Dry matter, organic matter, pH, compaction, grain size, porosity and soil composition were found to have a significant impact on various soil processes and soil organisms. Field investigations were made to examine dry- and organic matter and pH. The results were indicating that dry matter increased and that the organic matter decreased when the area was refilled with a coarse material. This study showed that there should be requirements on the characteristics of refilling material such as; organic matter content, good water holding capacity, a pH that is as neutral as possible and that the soil should not be too compact. A conclusion from this study was that crushed rock may not be the optimal refilling material after soil remediation.
