Concern over the presence of ammonia at Goderich's Memorial Arena has been removed, now that the chemical itself is gone.
In a recent e-mail to municipal staff, Goderich YMCA general manager Anne Marie Thomson reported that 27-hundred pounds of ammonia had been taken away from the former rink.
Memorial was closed as an ice facility earlier this year, due to safety concerns tied to an engineer's report that the pipes that carry the chemical from the ice plant are in poor condition.
While the nearly 70 year-old Memorial Arena is still used for other purposes, it's loss as an arena leaves Goderich with a single ice pad at the Maitland Rec Centre.
Now, only two arenas are left in Canada that still use ammonia as a refrigeration agent.
