This report is part of a series of research reports that describes the results of investigations funded under the Alberta Oil Sands Environmental Research Program, which was established by agreements of the Governments of Alberta and Canada in February 1975. This ten year program was designed to direct and co-ordinate research projects concerned with the environmental effects of development of the Athabasca Oil Sands in Alberta. The objectives of this report are to summarize water quality constituents in the AOSERP study area and to examine relationships between these constituents and changes in land formation, hydrology, and development.
