Large-scale cleanup of petrochemical site

Published June 23, 2025

At a petrochemical site in the Rotterdam port area, Verhoeve Netherlands is currently remediating a large-scale oil / aromatics contamination in soil and groundwater. Much of our proverbial "toolbox" is being used to complete this job.

The unsaturated zone is remediated by compartmentalized excavation and external soil cleaning. Subsequently, the pure product present (in the form of a floating layer) is removed by multiphase extraction (MFE).

Once this bulk is removed, post-treatment of soil and groundwater takes place through groundwater extraction, biological above-ground stimulation and subsequent infiltration of treated water provided with nutrients. In addition, simultaneous biosparging takes place to further stimulate aerobic degradation in-situ. The set of techniques will remain operational until 2030.

This project is also characterized by limiting inconvenience and seeking combination benefits by making "work with work." Simultaneously with the soil remediation work, we are realizing a sewer renovation (GRE sewer) and tank dike renovation.
