Description

Presents an enhanced sampling design for deployment in the Lower Athabasca River. It represents one component of work to describe baseline environmental conditions in the Lower Athabasca River prior to the potential release of coke slurry-treated oil sands process affected water (OSPW). The document describes sampling locations and sampling frequency to establish a comprehensive description of baseline environmental conditions in surface water chemistry, benthic sediments, benthic algae, benthic macroinvertebrates, and small-bodied fish.

Description

This technical report, compiled by Hatfield Consulting, describes the experimental design used to determine the toxicity of oil sands process-affected water (OSPWW) treated using Syncrude's coke-slurry treatment process. The three primary components of the study design are: chemical characterization of untreated and treated OSPW; toxicological testing of treated OSPW; and assessment of aquatic invertebrate community mesocosm responses to treated OSPW.

Description

This study investigates key issues identified in the Joint Canada-Alberta Oil Sands Monitoring program regarding water quality of tributaries to the lower Athabasca River, specifically: the current state of water quality; the distribution of contaminants; whether the presence of toxic substances is increasing or decreasing, and their rate of change' and whether substances added to the rivers by natural and man-made discharges are likely to cause deterioration of water quality.

Preliminary report of Athabasca River water quality results in response to the Obed Mountain Mine release

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... More ≫

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.
