Validity of effluent and ambient toxicity tests for predicting biological impact, Skeleton Creek, Enid, Oklahoma

Skeleton Creek was studied in August, 1983 and was the fourth site study. A small creek, Boggy Creek receives discharges from both an oil refinery and a publicly owned treatment works (POTW) prior to its confluence with Skeleton Creek. A fertilizer-processing-plant discharge is located on Skeleton Creek just downstream of the confluence of the two streams. The toxicity of two effluents and ambient stream stations was evaluated. Hydrological and ecological field surveys were also done. A comparison of the relationship between the measured toxicity of the water samples collected from the streams and the health of the aquatic community at the same stream stations is made.
