A water balance for the Athabasca River was developed which accounted for all the major withdrawals and discharges to this river. Current annual rate of withdrawal from the river is 2.34m3/s

Goal of the project was the establishment of criteria safeguarding fish from toxic effects of mixtures of vanadium, nickel, and phenol to fish; all are associated with oil sands developments

To document the natural heavy metal geochemistry of the sediment and to assess cultural influences if any on concentrations. Absolute concentrations are low compared to data for polluted sediments

Dredged sediments and sediment cores were collected from sites along the Athabasca River system from between Fort McMurray and the confluence of Riviere des Rochers with the Slave River

Studies of the water quality of the Athabasca Oil Sands area streams, rivers, and lakes have been conducted by numerous organizations and government agencies since the 1950’s

Locations of Athabasca Oil Sands area water quality sampling sites; sampling, analytical and quality control methods used; volume and availability of assembled data; and an appraisal of data quality

Seasonal and areal variations in significant water quality parameters in the Muskeg River basin of northeastern Alberta are described

Deciduous trees and shrubs were much more sensitive than conifers, presumably because SO2 can enter broad leaves much more easily than needles. Jack pine was more sensitive than spruce

A set of 11 sites were established in the Alberta Oil Sands Environmental Research Program study area to provide baseline information on vegetation and soils with respect to air pollution impact

No measureable air pollutant effect was observed on either vascular or lichen communities at any site even though significantly high tissue pollutant concentrations were documented within 10km of GCOS
