In Fort Saskatchewan, Alberta, a public hockey rink at the Dow Centennial Centre has been shut down after a slab leak was discovered, the Fort Saskatchewan Record reports.
The newspaper states the skating rink's refrigeration system failed and began leaking glycol through the cement beneath the rink.
"The problem is in the ground under the ice surface," Chris Cambridge, the city's general manager of public works, told the paper. "We don't know exactly where, but by turning valves on and off, we know it's somewhere under the leisure ice." He added that the city will no longer use glycol after repairs are made.
Though glycol can be harmful environmentally, Cambridge told the paper that he doesn't expect any issues to arise from the leak.
Cimco Refrigeration, which installed the system in the Dow Centennial Centre, states on its website that it put in an energy-efficient "ice battery" to cool the hockey rink. The glycol used is cooled to keep the rink frozen, and heated up for other areas of the complex.
