Soil Preliminary Investigation

A soil preliminary investigation is a mandatory investigation that must be conducted before certain soil-affecting activities take place. This investigation establishes the initial quality of the soil and serves as a reference point for later checks. It is a legal obligation under the Besluit activiteiten leefomgeving (Environmental Activities Decree).

The preliminary investigation provides insight into the current condition of the soil and helps determine whether activities can be carried out without unacceptable risks to soil quality. Results must be retained for possible later inspections.
