Aannemingsbedrijf Aertssen rids Lokeren of soil containing mercury in the heart of the city. The clean-up activities started at the end of November and will soon provide space for sustainable project development.

The facts: historic activities at a fur-cutting and dying plant - where, until recently, a Colruyt supermarket was located - had left the Molenbergplein in Lokeren seriously contaminated. Since mercury was present in both the soil and in the groundwater, our professionals were called on to help.

Excavation and recycling
After the demolition of the supermarket buildings, we started excavating the site to a depth of 5 m. The contaminated site is 7,000 m² in area and contains at least 20,000 tons of mercury-contaminated soil. That volume of soil was taken away to a soilrecycling centre, where it was processed into clean sand.

The ground-water problem will also be tackled: in the coming two years, it will be purified by an ionexchange installation specially developed for this. This installation adsorbs the mercury particles from the groundwater that is pumped up. So - in return for a contaminated site - Lokeren will soon get a site for sustainable project development. And if that’s not a good deal...
