Reason Ozone odour near the ISCO installation identified

21 January 2015

During the Christmas holiday period, an ozone odour was detected near the container of the soil vapor extraction system. The cause of this ozone odour has been investigated and identified. The blowers of the SVE installation inside the container are no longer airtight.  The seals were corroded.  The 4 blowers will be replaced.  During the inspection of the SVE system a malfunctioning of the in-line ozone meter has been noticed.  The ozone meter will be revised. 

The planning of the inspections of the installation has been intensified as a consequence of this incident: from two times per month to weekly.
