Greased soil cleanup in the center of Horst

Situation

Horst equipment

A large floating layer of mineral oil at groundwater level is the silent witness of a nasty pollution in the heart of Horst. Heavy fuel oils and aromatics are present in the soil of a former oil and distribution depot in this municipality. Excavation is only part of the solution. Vissers Oliehandel Horst BV calls on our cleanup expertise. We offer them a fixed contract price with guaranteed results. Детальная информация marketing online тут.

Our approach

Location Horst

In January 1998, we begin the intensive phase, going to a depth of eight meters below the surface. The soil, consisting of loamy fine sand has to be heated up to 80 degrees Celsius — an optimum temperature needed to mobilize and remove the heavy oils and aromatics. 21,000 liters of oil are being collected from the soil. In July 1999, the soil remediation is finished and approved by the regulators. Groundwater cleanup continued until 2002.
