- It is very nice that there was nothing in these individual wells, but much more sampling needs to be done to find out what it looks like on Rörberg, says Gävle municipality's environmental manager Patrik Gustavsson

High levels of PFAS substances have been found in both surface and groundwater in virtually the entire airport area.

The consultant reporter suggested that the municipality should take samples in about 30 individual wells, but only five were chosen.

Major investigation underway

According to the environmental manager, a major survey of the airport is planned and new sampling is expected to take place early after the turn of the year.

Depending on the results, sampling may be required in several individual wells.
