Determination organic and inorganic chemical composition
Chemical composition of soil is important for two reasons:
• To determine chemical proporties of soil
• To establish if the soil is polluted and weather imobilization may be requiered
Tests in the laboratory are necessary for both purposes.
Organic and inorganic substances often found in soils are shown in Table below as are the Dutch requirements regarding the protection of the environemnt for a particular substance (focus is on groundwater quality protection).
