Metgasco inspires a lot of confidence when it openly speaks of abandoning the Glenugie test well after attempting to seal its 800 metre length with a concrete pour.
There is no mention of any form of periodic monitoring of the integrity of this plug.
The 'rehabilitation' of such wells has been known to deteriorate over time in some instances and, I'm sure that this particular corporation will expect the community to monitor its old exploration sites and local government to pick up the tab for any necessary initial investigations in the future should problems occur.
By then the directors and major shareholders will have moved on to pastures new.
