Because aquatic-life guidelines have been exceeded in samples, have there been any physical effects of fish in the basin?
Aquatic-life guidelines are established to protect wildlife species from adverse effects such as mortality, reproductive impairment, and organ damage. In one part of the study, fish were examined for external deformities, eroded fins, lesions, and visible tumors (DELT anomalies) during sampling; a weak but significant correlation was found between these physical symptoms and the benthic invertebrate pesticide toxicity index (PTI), a composite measure of the toxicity of pesticides found in a stream-water sample. Also, Ohio EPA has reported that high nutrient levels in streams in the Great and Little Miami River Basins were associated with higher rates of DELT anomalies in fish.
