Speaker Bio:

Inge graduated in 2002 from the Department of Industrial Technology and Construction in Ghent. Her dissertation on MTBE (a substitute for lead in petrol) in soil and groundwater, rewarded with a distinction, illustrates her interest in the subject of soil pollution.

She gained her first experiences in soil management working for a consultancy company. Her work focused on the management of the use of excavated soil.

In September 2004, Inge started working at the Public Waste Agency of Flanders (OVAM). Very quickly she became involved in the issues of soil pollution, remediation and pollution mitigation and management. For more than 10 years she has been working with great dedication to find the best and most efficient strategy, within the existing legal and binding frameworks, for each remediation case. Quality, combining soil remediation with redevelopment and communication are key for her.

In 2007 she coordinated the remediation of creosote contaminated soil in Ostend, the first phase of this operation happened alongside the construction of the new AZ Damiaan Hospital. In Blankenberge she was responsible for the remediation of a former manufactured gasworks site during an integrated process that also included the construction of an apartment building. Her most prestigious project, the Waalse Krook in Ghent, was realized in 2013. On the old manufactured gasworks site the new city library was constructed. In 2013 she also took the lead of the newly created team whose actions are focused on the remediation of the manufactured gasworks sites in Flanders.

Inge attaches great importance to knowledge production and knowledge sharing. Her collaboration with the CityChlor project has resulted in the co-authorship of an article on the use of the Enissa technique, that was presented at the Batelle conference in Monterey (2012).

After participating in the MGP 2014 conference in Florida she became the driving force behind the MGP 2015 in Ghent.


Following on from our presentation at the MGP conference in 2015, this presentation will first give an update on the current state of affairs and the lessons learned so far. Additionally we will look into the redevelopment of the Tondelier site in Ghent in more detail. The site was visited during MGP2015, when the remediation has just been started and visitors were curious about the progress of the remediation on this site. During the presentation, I’ll proudly present you where we have gone from there. More specifically we will assess whether the balance between soil remediation and redevelopment is still in place. The major challenges that were encountered during the process will be highlighted as are the lessons learned. The question of what we would have done differently is answered from both the perspective of the soil remediation contractor and the developer.
