The 2020 and 2021 documents acknowledge tailings were seeping from the ponds that were supposed to contain them
. The tailings were detected at monitoring wells within the mine’s lease area, about 70 kilometres north of Fort McMurray.
In May 2022, the seepage was reported to First Nations and communities as discoloured water pooling on the surface. They received little information after that until last February, when the regulator issued environmental protection orders against Imperial – and then only after 5.3 million litres of contaminated waste water escaped from a holding pond.
“Imperial shared this information with the and communities in early 2021 and has provided annual updates.” The seepage at Kearl continues. Data posted on the regulator’s website shows several test wells continue to show hydrocarbon levels in surface water that exceed provincial environmental guidelines.
