The soil remediation operation has not yet been completed. Soil remediation in the Netherlands still needs innovation in order to carry out remediation faster, more effectively and above all cheaper. Biological degradation processes play a crucial role in this. Processes that Orvion measures with the latest DNA technology and accelerates with concentrated bacterial cultures.
New bacterial species are discovered every year. We are continuously expanding our range of ORVIdetect qPCR bacterial analyses. With ORVIdetect we can therefore effectively determine whether degradation of chlorinated solvents, such as PER and TRI, occurs at your location. We can also demonstrate the occurrence of natural or stimulated degradation for other chlorinated solvents (chloroethanes such as 111TCA, chloromethanes such as Chloroform, chlorinated benzenes, chlorofluorocarbons (CFCs/Freons). For biological dechlorination important bacterial species such as Dehalococcoides, Dehalogenimonas and many others we can quickly and effectively analyze in groundwater sample.
We can also determine the presence of specific bacteria and bacterial genes responsible for the degradation of these substances for common oil-related contaminants such as the mobile aromatics benzene, toluene, ethylbenzene, xylenes and naphthalene, but also fuel additives such as MTBE and ETBE. We are also working on the breakdown of pesticides such as mecoprop/MCPP and many other substances.
An important area of research is the biodegradation of PFAS. These substances were always considered to be non-biodegradable (“forever chemicals”), but it has now been shown that biodegradation is still possible. We investigate these biological possibilities in collaboration with Princeton University and Dutch universities and institutes, among others. Please contact us if you are interested in the possibilities of PFAS degradation.
Orvion has the process certificate BRL 6002, for supervising biological in-situ remediation and aftercare. Our soil project leaders and environmental supervisors have extensive experience in carrying out soil investigations, drawing up remediation and aftercare plans, designing biological remediations, drawing up groundwater models in which geohydrology, material transport and degradation are modelled, feasibility studies and supervising biological remediations.
Our approach is characterized by taking the natural possibilities of the soil as the starting point. For an effective approach, it is necessary to first determine whether the natural degradation of the contamination occurs in order to be able to make optimal use of these natural processes for the remediation solution. This approach is more sustainable and often cheaper than conventional purification methods.
