Abstract
The potential environmental hazard of an in-situ shale oil process wastewater to aquatic organisms was investigated by determining the acute toxicity of this effluent to Daphnia-magna, a microcrustacean commonly found in lakes in northern and western North America. The effluent under study, designated Omega-9 water, was obtained from the Laramie Energy Technology Center's experimental true in-situ shale oil site. A synthetic effluent was prepared by mixing together each of the major inorganic components identified in the Omega-9 water and at the concentrations found. Results of the acute bioassays for the Omega-9 water and the synthetic mixture indicated that the Omega-9 water was about 1.5 times as toxic as the synthetic. These results indicated an important role for inorganics, particularly unionized ammonia, in the toxicity of the Omega-9 water. The authors also suggest that not all the toxic components of the original effluent have apparently been identified.
