A pipeline carrying industrial waste in Alberta recently leaked 9.5 million liters of waste water into Canadian wetlands, according to a Calgary Herald article.
The spill came from a pipeline owned by Apache Canada. Since 1975, the company has been responsible for 949 document spills.
A cleanup for the spill is in-process now and workers are monitoring environmental conditions near the spill.
None of the waste water, which contains industrial tailings from oil and gas production, is known to have entered the nearby Zama River.
Waste water did enter sensitive wetlands, though the effects are not yet known.
