Laboratory scale model streams were developed to assess the effects of oil-shale-related effluents on aufwuchs. The model stream design allowed variation of water temperature, chemical composition, flow rate, and illumination intensity and periodicity. Chemical constancy of the stream water was provided by continuously metering new water to the streams with doses of test effluents. Omega-98 water, the experimental retort water used, was studied at dilutions between 0.013 and 2.12 percent for 9 days. Day 3 samples generally showed stimulated growth at 1 percent or more Omega-9 water concentration. The more dilute effluent loads stimulated growth throughout the test period. The most marked effect of Omega-9 water was to lower the proportional contribution of diatoms to the aufwuchs biomass. 9 refs.
