The colonization of limestone bricks and bitumen coated limestone bricks by benthic river organisms was followed over time. After nine weeks of colonization, no massive increase in the numbers of bacteria on the bitumen was noted, suggesting that degradation was not proceeding rapidly. However,...

Vanadium concentrations of 2.4 to 5.6 mg/L were lethal in 7 days to rainbow trout of wet weight 1.2-6.2 g. The LC50 varied slightly over the 12 combinations of water quality, from hardness 30 to 350 units and pH 5.5 to 8.8. The 7-day LC5O may be estimated by the following equation, which...

Mine depressurization water obtained from five wells on Lease 17 held by Syncrude Canada Limited, was examined for chemical composition and acute toxicity to two species of fish. In the first series of experiments, mine depressurization water was diluted with various proportions of water...

Volume 2 In order to conduct oil sands mining operations in the surface mining region of the Athabasca oil sands deposits, most regions require depressurization of the basal sandstone formations. The groundwater produced by depressurization operations is of poor enough quality to be toxic to...

The achievement of satisfactory air quality entails the adoption of one or more air pollution control strategies. Of the four basic strategies available, only air resource management requires the use of air quality models. Atmospheric dispersion models are a subset which can be employed either...

The third in a series of Atmospheric Environment Service Field Studies in the Alberta Oil Sands Study Area was carried out during June 16-27, 1977. The study was designed to cover the same objectives as those of the previous two studies but for summer conditions. As a consequence, the AES...

The second in a series of Atmospheric Environment Service field studies in the Athabasca Oil Sands area was carried out during 3-13 February 1977. The objectives of the study were the same as those of the March 1976 study, namely to obtain information on the meteorology of the area and/or the...

A climatological air quality dispersion was developed which provides more powerful analyses capabiIities than are avaiIable in traditional CDM-type models. The model incorporates a time series approach to satisfy identified user needs. The three components of the model are: the time series file...
