Teck Resources Ltd has reported and “is investigating another spill at its Trail smelting complex in British Columbia, but said on Sunday it does not expect the incident to have a long-term impact on fish or the environment,” reports Reuters.
“Up to 25 cubic meters (883 cubic feet) of a solution containing some sodium hydroxide was released into a sewer line on Tuesday, Teck said in a statement. The sewer leads to a treatment plant that discharges into the Columbia River.”
“Sodium hydroxide is a corrosive chemical that when concentrated can burn and blister skin. The liquid released at the Trail facility, home to one of the world’s largest zinc and lead smelting and refining complexes, was diluted with water.”
“‘Initial information indicates that the sewage treatment plant process may have diluted the high pH solution somewhat but otherwise had a limited effect,’ Teck spokesman Richard Deane said in an email on Sunday.”
“Deane said Teck is investigating the incident, and outside experts will complete an environmental impact assessment.”
