Oil shale reserves in Piceance Creek and the White River, Colorado, contain retorted-shale piles which may pollute th eground water through leaching. Bioassay experiments were carried out to determine the effects of leachates on algae, particularly ANABAENA FLOSAQUAE and SCENEDESMUS. Tests were done to establish inhibitionary concentrations of the leachates from various sources of spent shale. Retorted-shale leachates had major effects on the algae papulations at a 40% concentration, minor effects at 8%, and no effects at 0.4%. Discrepancies between experimental results and actual retorted-shale piles are dixcussed. (JMT)
