“Given that risk, I’m amazed that we didn’t… the lead-in wasn’t that ‘we want these tanks out.’ I realize it’s not going to happen tomorrow, but it seems to me the end result is we need these tanks out of the ground,” Woodcock said.
Albisser replied that another approach is to detect leaks early on.
“It may seem like a very passive, or not a very aggressive, approach,” he admitted.
“However, the hydrocarbon plume in the ground does tend to flow quite slowly, it’s likely several years out before a contaminant that is 300 metres or so away from those wells, that it would reach those wells.”
Albisser said the city is also installing a line of monitoring wells that will indicate if the ground water is becoming contaminated.
He also said that if any fuel tank is found to be leaking, “we would likely require that those tanks be abandoned, however there’s significant financial impact to that.”
