Samples were taken to analyze the river waters for chemical composition and bacteriological constituents on a regular basis. Loadings of Biochemical Oxygen Demanding materials were not found to be high. Dissolved Oxygen levels remained above the Provincial Board of Health guideline of 5 mg/l. The water quality in the Athabasca River and its tributaries was found to be generally acceptable throughout the winter of 1969 - 1970. However, relatively high odor and colour values were observed on occasions during the past winter. The color can be attributed to a large extent on natural causes. </style></abstract><custom2><style face="normal" font="default" size="100%">Athabasca River, Fort McMurray </style></custom2><custom3><style face="normal" font="default" size="100%">http://www.worldcat.org/oclc/70465672</style></custom3><custom4><style face="normal" font="default" size="100%">OSEMB</style></custom4></record></records></xml>
