Chemical plume spotted on Lake Superior
A 50 metre long plume was spotted on Lake Superior near Marathon, Ontario – close to where pump and chemical trucks have been cleaning up after black liquor leaked from a section of a five-kilometre effluent pipe about 10 days ago.
There are currently no concerns that the material could get into drinking water, because the nearest intake pipe on Lake Superior is located 80 kilometres away in Terrace Bay.
The sighted plume is the latest glitch to hamper the transfer and cleanup of about one million U.S. gallons of the diluted liquors that were left on site following the bankruptcy of Marathon Pulp last March.
The effluent pipe that leads to a secondary treatment plant has leaked three times since the operation began in early December. Earlier this month, a storage tank inside the dormant mill was found to be leaking.
A good portion of the liquors have been trucked off site to the AbitibiBowater pulp mill in Fort Frances.
About 150,000 gallons being vacuumed up from the site of the third leak is to be transferred to a spill basin east of town and at the end of the pipe.
