2. Based on the sampling data you obyained and the information in the literature, were you able to rule out any possible causes of death? If so, which ones and on the basis of what data? Dissolved oxygen was a substance whose natural level of concentration matched the data I obtained. This information made me assume that the lack of oxygen wasn’t the problem in the lake. Both mercury and the pesticides were also under the toxic level that the information provided. Finally calcium, based on the information, seemed to have no affect on aquatic life. 3. Based on your sampling data, what hypothesis did you form to explain why the fish were dying? Write one specific and concise sentence. The high concentration level of iron is what is killing the fish in the hatchery. 4. Explain what specific data from your analyses and from the literature led you to the hypothesis above. Be concise. Both lead and iron had high levels of concentration in the lake, but lead had inconclusive information and its high levels could have been the cause of lead-bearing
