Installation restarted

27 February 2015

In the meantime the 4 blowers and the in-line ozone meter have been replaced.  After the restart of the injections in the Midway, the ozone concentration in the extracted soil vapour was increased (0,05-0,5 ppm).  The injection wells have been tested individually and these tests showed that the elevated ozone concentrations were caused by some individual wells.  Fortunately these wells were located in areas where the remediation target was (almost) reached and they have been bypassed. Also well-functioning injection wells that are located in areas where the remediation targets have been reached, have been bypassed. After this bypassing the ozone concentrations in the soil vapour extraction decreased again to normal values.  

However, the ozone concentration will be monitored more intensely in the first period after the restart.
