For the past two years, there has been a lot of news about a “new” contaminant, “PFAS,” which has caused a lot of inconvenience in the construction and soil industries. Recently it was demonstrated in America that there is a bacterium that breaks down this worrying group of substances. Geofoxx …
In-situ remediation can be quick – faster than many people think. Orvion has designed an in-situ remediation plan for a site in Bilthoven and has provided their environmental expertise. This remediation was completed within one year; the intervention value in soil and groundwater was amply achieved. A gas station used …
The soil on the WAVIN site in Hardenberg has been contaminated with solvents for a long time. These substances were formerly used as a degreasing agent. WAVIN has been controlling this groundwater contamination since the 1990s. Groundwater was pumped up and cleaned above ground. But the problem was not definitively …

We know more and more about microbiology. DNA detection equipment is becoming cheaper, as a result of which more and more new bacterial species and their degradation processes are discovered. The size of biodiversity in the world is displayed in a article in nature : the Tree of Life. It …
The ground on the WAVIN Services site in Hardenberg has been contaminated with solvents for a long time. These substances were formerly used as degreasing agents. WAVIN has been controlling this groundwater contamination since the 1990’s. Ground water was be pumped up and treated above ground. But this approach was …
We performed a biological source remediation in a residential location in The Hague (Gillesstraat). In the treated source zone we measured PCE (20,000 µg/l), TCE (2,900 µg/l), CIS (7,300 µg/l) and VC (
Scientific research does not stand still. New types of bacteria are being discovered every year, such as those involved in the degradation of benzalkonium chlorides (BAC, a cleaning and disinfecting agent) and in 2017 a species that anaerobically degrades benzene. Many contaminants can be degraded by bacteria, also in soil …
When selling or redeveloping a plot or location, the suspicion of a soil or groundwater pollution being present brings along obligations. Orvion makes an inventory of soil pollution that are presen and a remediation strategy so that you not only know the extent of the contamination, but can also gain …
Client: City of The Hague Question: Design, tender and guidance of the implementation of the biological in-situ remediation of the J. Gillesstraat in The Hague Work done: Development and design of a alternative approach to the remediation of CVOCs. Planning, design, modelling, selection of contractor, preparation of the remediation and …
Client: The Province of Noord-Brabant Question: Specialist in-situ soil remediation and geohydrology Work done: As a result of the destructive fire on the premices of Chemie-Pack in Moerdijk, the local soil and water have been severely polluted. Orvion has been asked by the Province of Noord-Brabant to act as in-situ …
