Soil Plan Zealand: Classification of polluted soil §

In Denmark each county defines what clean soil is, and when it is polluted. This causes some confusion, you have to remember that we have approximately 10 counties and 44,000 square kilometres !

However, the counties on Zealand and surrounding islands have decided to use the same standard. The name is “Jordplan Sjælland” which means “Soil Plan Zealand”. It is updated once or twice a year.

The guideline is only meant to last until some national standards are made by the Danish EPA.

Definitions

Class I soil is regarded as clean, and there are no restrictions on the use of it.

Class II soil is slightly polluted. It can be used under roads etc. where access to the soil is prevented.

Class III & IV soil is polluted. When moved it should be cleaned or placed on special dump sites where it does not pose threats to groundwater, man or beasts.

Classification of polluted soil

Class is determined by highest concentration. All values in mg/kg soil DM
