Description
A dyke failure on the Obed Mountain Mine site in the Hinton region on October 31, 2013 caused the release of an estimated 670,000 cubic metres of process water and suspended sediment into the Apetowan and Plante Creeks. These creeks merge into the Athabasca River downstream of Hinton. A number of government departments and agencies have actively been involved in responding to this event. This preliminary report summarises the first week of analytical sample data collected by Environment and Sustainable Resource Development (ESRD) and analysed by both ESRD and Alberta Health Services. Current near real-time turbidity data is also included.
