A water bottom examination has the purpose of establishing if serious soil contamination exists near the water bottom. It aims to provide a description of the nature, quantity, concentration, origin and extent of polluting substances or organisms, the possibility of the dispersion of these substances or organisms, and the danger of exposure to people, plants, animals and groundwater and surface water.
In addition, a water bottom examination can include data concerning the assessment of the danger of the exposure of the soil contamination to people, plants, animals and groundwater and surface water with a potential other use.
A water bottom examination consists of a historical examination and the sampling of the water bottom and soils that can be contaminated as a result of the spreading of the contamination of the water bottom or the surface water.
A water bottom examination is conducted under the supervision of a land remediation expert in conformity with the standard procedure drawn up by the Flemish Government. In the absence of such a standard procedure, a water bottom examination is conducted according to a code of good practice.
A water bottom examination can be carried out in phase in the cases and in accordance with the conditions determined in the standard procedure mentioned in §3.
