Oil pollution at Østerstrand is removed by biological remediation
On Thursday, October 3, 2019, Ejlskov began the biological remediation of a 30-year-old oil pollution in the Østerstrand area of Fredericia. The case has received a great deal of media attention, and you can read some of the articles here:

BioRemediation of oil pollution at Østerstrand, Fredericia.
Now the underground biological barrier is established at Shell’s port terminal – even a few weeks faster than expected.
During the summer of 2018, Ejlskov completed site investigations and prepared an in-situ cleanup program for a Chinese industrial company, restoring an oil-contaminated site.
Now a Chinese team has been established to support Ejlskov by the in-situ installation on site. A task, that requires the exact distribution of carbon-based injectates (CBIs) into the soil and injections at appropriate intervals. Ejlskov’s site manager, Italian engineer Giorgio Ceriani, is on the job, and he enjoys the collaboration with his Chinese colleagues.
“It´s amazing how committed and passionate our newly established Chinese crew performs”, he says. “It´s really a pleasure to work with these guys. Thanks to their dedication, everything runs on schedule, and we expect the installation to be completed within the next 5 – 10 days”.
Ejlskov Trap & Treat BOS 100® in-situ technology proves high potential for groundwater protection and treatment of sites contaminated by explosive compounds. Positive results from a pilot test performed in July 2018 by Ejlskov for one of its clients, now show evidence that BOS 100® effectively degrades problematic explosive compounds such as Trinitrotoluene (TNT), Cyclonite (RDX) and Trinitrobenzene (TNB).
The trial area covered approximately 50 sqm and the execution of 8 injection points with treatment depths between 10 and 15 meters below ground level (m bgl). After years with contamination in the area, a significant decline in the presence of explosive compounds is now being observed.
Regular groundwater monitoring will continue throughout 2019 for further evaluation and verification of the successful achievements so far. Work learnings from the project will eventually form the basis for future remediation efforts on larger scale.
