[1][2][3] Spatial interpolation allows for more efficient approach to remediation and monitoring of soil and water contaminants.
[4] As a result, environmental agencies are placed in charge in remediating, monitoring, and mitigating the soil contamination sites.
Also, some of the most soil contaminated areas are around the mines such as the ones in Slovenia, Bosnia and Herzegovina, and in United States (Sulphur Bank Superfund Site, in California).
[3][6][7][2] Using the inverse distance weighted (IDW) method from geostatistical tools in ArcGIS 9.3, a raster model of the Hg concentration has been produced for the Idrija area.
The developed map is a combination of multiple layers that are stacked on top of each other as shown in Figure 1.
