Information Update

Most recently reported location: The front of the sediment path was observed today 141 km north (downstream) of the town of Athabasca.

Remediation Efforts

So far, our immediate remediation has focused on:

  • Sediment removal from the Apetowun and Plante Creeks, as well as the junction of Plante Creek and Athabasca River.
  • Installing straw bales to filter sediment in the two creeks.
  • Working with third-party emergency responders for immediate clean-up and long-term remediation.

Long-term planning is now underway to identify what remediation and reclamation can be done during the winter months along the Apetowun and Plante Creeks.  Further details will be provided once they become available.


We continue to conduct daily water sampling upstream from the incident location as well as at established points downstream. Water samples are also conducted daily at the leading edge of the sediment path.

  • Biophysical assessment continue at confluence of Plante and Emerson Creeks.
  • Benthic microinvertebrate testing has been completed at 6 locations on the Athabasca River.
  • Sediment sampling is complete, and all samples are currently being analyzed at the lab.
