In this area, the old gas production industry has caused major pollution in the soil.

Samples show that significant pollutants of PAH compounds, cyanides, BTEX, phenols and cresols are right down to the rock surface and large masses are today classified as hazardous waste.

Traces of contamination have also been found in water samples, which means that dangerous substances are spread from the area through the groundwater. However, there are low levels and the risk is considered small for human health, says environmental engineer Anders Nyberg.

In order to protect the water supply and the environment for the future, it is estimated that between 18,000 and 20,500 tonnes of masses need to be addressed in the area of ​​remediation.

The issue of the contaminated area has been relevant for many years. See here our feature from SVT's archive
