Update on PFAS Soil Treatment Facility Works

Over the past few months, several preparatory works have been carried out: 

• The staff entrance has been widened. 
• Concrete slabs have been laid to make the site compound accessible. 
• Site cabins have been installed. 
• Extensive underground piping has been constructed.  

In addition, concrete has recently been poured for the so-called sludge collection pit. This pit will collect all water coming from the site, which will then be pumped into the wastewater basin. The pit is located between two water basins, which will be further constructed in the coming weeks. These basins are expected to be completed by the end of October.

The next step is to construct the liquid-tight concrete floor on which the facility will be built. These works will begin shortly and are expected to be completed by early 2026.

Not only will the soil remediation be carried out emission-free, but the construction itself is also being done using emission-free equipment wherever possible. BAM is deploying both small and large electric machinery. A great example is the fully electric 25-ton Caterpillar crawler crane. This crane is charged overnight and operates throughout the day. This is a joint initiative by BAM, subcontractor Baars, and Schiphol, making the works quieter and cleaner.

The facility is intended to remediate PFAS-contaminated soil from Schiphol. This soil is currently stored at various depots next to the Zwanenburgbaan runway. The contamination stems from the use of PFAS-containing firefighting foam at Schiphol, which was previously mandatory for tackling liquid fires. We expect the soil treatment facility to be operational by summer 2026.
