Nearly 6 million litres of water from oilsands sediment pond released into Athabasca River

Suncor has reported six million litres of water that exceed sediment guidelines have been released into the Athabasca River from a pond at its Fort Hills oilsands mine. "Suncor took action to stop the discharge system and the release has been stopped," said a note from the Alberta Energy Regulator sent to area First Nations on Monday. The note said the water is from a pond used to settle suspended solids in surface water that runs in from various parts of the site. The water has drained from muskeg, rock and soil overlaying the bitumen, material being stored for reclamation and other areas of the site that are undisturbed by mining.

Husky Oil fined for contaminated water release into Saskatchewan river

Husky Oil fined for contaminated water release into Saskatchewan river

Husky Oil has been fined $600,000 for releasing a harmful substance into a river in Saskatchewan. The Calgary-based oil and gas producer pleaded guilty Friday in provincial court to depositing the substance into a waterway full of fish. The charge came after the release almost four years ago of about 2.8 million litres of process water, a byproduct of oil and gas production and typically high in salt content.

New technique could help decontaminate oilsands process water

New technique could help decontaminate oilsands process water

New technology developed by engineers at the University of Alberta shows potential in cleaning and decontaminating process water from oilsands production. The process relies on ozonation and biofilters to remove organic compounds from contaminated water. The study, published in Science of the Total Environment, demonstrates that the method, previously used to clean pharmaceutical waste water, efficiently removes naphthenic acids, considered to be one of the main contaminants in oilsands process water.
