​Map showing areas with polluted soil​

​Facilitating efficient management of polluted soil areas, COWI developed JAR – the national register of soil pollution. The system is to support the Danish regions in implementing the Soil Pollution Act.

​When the Danish Parliament passed the Soil Pollution Act in 2000, a number of counties put out to tender the development of a system – the national register of soil pollution (JAR) – that was to be used for mapping and continual management of polluted soil in the then Danish counties, now regions. 

Web-based IT system merges vital pollution data

COWI in collaboration with Traen A/S was tasked with developing JAR. The register is developed as a web-based IT system that is to support the then Danish counties (now regions) in implementing the Soil Pollution Act. The system retrieves and combines data and geographical information in new ways, depending on existing and future needs.

To this end, information was collected from internal and external data sources, including database entries, recorded documents, GIS data and analogue data. The data model of the JAR system contains all the data needed to provide decision-making support and facilitate case processing in the regions. As an example, GIS data is integrated with alphanumerical data.

System prioritising validity and user-friendliness

The main purpose of the register is to protect drinking water resources, to prevent health problems due to use of polluted areas and to create the basis for coordinated public efforts aiming at preventing further soil pollution.

In practice, this is done by using JAR, which provides users with access to:

  • efficient management of polluted areas.
  • valid data that can be used for reporting and updating pollution data
  • national and international statistics and comparisons.

Furthermore, the system is integratable with other systems such as ESDH used by the Danish regions and central DKjord under the Danish Nature & Environment Portal. Data can also be exchanged with other specialised IT tools, complimenting JAR's applicability and efficiency.
