Environmental Assessment Studies

Environmental Assessment Studies relate to investigations in which environmental quality and associated risks are determined, and mitigating solutions are engineered. This involves amongst others studies on air quality, soil and groundwater, both on local and regional scale. A few examples:

Investigation into persistent organic pollutants, Tajikistan

The presence of persistent organic pollutants (POPs) in the environment, especially pesticides, is a worldwide problem. We have conducted several studies in this field worldwide. For instance at the Kanibadam burial site in Tajikistan. Associated risks were assessed using CALUX® (Chemical Activated LUciferase gene eXpression) assays.

PCB inventory study, Vietnam

For the power company of Vietnam (EVN) a national inventory study on the presence of PCBs in transformer units was carried out. Over 50,000 units have been sampled and analysed. Based on the results, management plans for the toxic oils were prepared for the various sites.

Site assessment degreasing facility, Denmark

In order to get a detailed insight in the distribution of severe contamination of chlorinated solvents, a soil quality survey was carried out. The results have been used to delineate the contamination in soil and groundwater, to prepare the Conceptual Site Model and to perform lab and pilot scale testing to determine remedial options. Flux calculations show that significant mass enters the groundwater system and remedial actions are therefore required.
