4.6 Karakterisatie bodem- en grondwaterverontreinigingen
Een samenvatting van de verontreinigingstoestand per perceel zoals beschreven in het
beschrijvend bodemonderzoek is weergegeven in Tabel 5.
In onderstaande paragrafen worden de verschillende verontreinigingskernen waarvoor een
saneringsnoodzaak geldt uitgebreider besproken.
4.6.1 Verontreiniging 1
De verontreiniging situeert zich in het noordelijke tankenpark en wordt onder meer aangetroffen in
de peilbuizen 111, 110, 106, 107 en 4002 . Ze is historisch van aard, daar ze reeds werd
vastgesteld tijdens de eerste bodemonderzoeken in 1995. Er is een drijflaag aanwezig van

minerale olie, waarvan het volume puur product op 1.330 m³ wordt geraamd. Er gaat geen
humaan toxicologisch risico of ecotoxicologisch risico vanuit, maar omwille van de aanwezigheid
van puur product werd er in het verleden een verspreidingsrisico toegekend aan de
verontreiniging, ook al werd in de jaren na het BBO tijdens de monitoringsronden geen
verspreiding van de drijflaag vastgesteld. De urgentie om tot sanering over te gaan werd in het
beschrijvend bodemonderzoek in klasse II onderverdeeld.
Op de concentratiekaarten in Bijlage G wordt de omvang van de verontreiniging zichtbaar. Deze
is afgeperkt en de afperking wordt in de uitgevoerde monitoringen na 2008 bevestigd. De
verontreiniging bevindt zich onder het tankenpark. De verontreiniging zou waarschijnlijk afkomstig
zijn van de tanks en het voormalige slecht functioneren van de waterzuiveringsinstallatie.
Verontreiniging 1 wordt voornamelijk gekenmerkt door minerale olie van de fracties C12-C20, en
ook in mindere mate C10-C12 en C20-C30. De resultaten kunnen worden teruggevonden in het
BBO (URS, 2008).
In onderstaande tabel worden de administratieve gegevens van verontreiniging 1 weergegeven.

mineral oil, the volume of pure product is estimated at 1,330 cubic meters. There is no going
human toxicological risk or ecotoxicological risk from, but because of the presence
of pure product was assigned a spreading risk in the past to the
pollution, although it was not in the years after the BBO in the monitoring committees
established distribution of the scum. The urgency to proceed with remediation was in
divided into Class II descriptive soil.
Extent of the pollution is visible on the concentration maps in Appendix G. This
is enclosed and the demarcation confirms the executed monitor creations after 2008. The
contamination is located under the tank farm. The contamination would probably come
of the tanks and the former malfunctioning of the sewage plant.
Contamination 1 is characterized mainly by mineral oil fractions C12-C20 and
also to a lesser extent, C10-C12 and C20-C30. The results can be found in the
BBO (URS, 2008).
