Evaluation of perozone injections in the tank farm

22 July 2015

The monitoring of extracted soil vapour and of ozone and/or VOC-emissions in the tank farm and below the tanks gives positive results: no emissions have been detected inside the tank farm nor in the extracted soil vapour.  The remediation neither influenced the stability of the tanks. 

With these good results in hand, the project team is planning to start the last phase of the remediation, being the perozone injections in the large source area in the tank farm, in August.  The start-up procedure will occur in different phases like for the small source area. Tests to increase the injection regime inside the tank farm and the midway are foreseen in September.
