Exp. 14 Procedure Proposal Template - Fall 2015Determining the Cause of a “Fish-Kill” in the Clark Fork of the Columbia RiverVeronica KitchensErich KolanLab Section # 038October 7, 2015Introduction In this experiment we will be analyzing simulated water samples from the Clark Fork of the Columbia River in an effort to determine if the water contains toxins that could have caused the “Fish- Kill” in 1984. If metal ions are found to be present it will indicate a contribution to water salinity, which in turn can be the cause of the fish kill. Wewill be testing out sample to determine if it contains ions of Cu2+ and Fe3+, which wouldindicate that the water is toxic. The result of this experiment will indicate whether or not the water in the Clark Fork of the Columbia River was the cause of the “Fish-Kill” in 1984.Performing this experiment will allow us to determine what ions make up our water sample that was gathered from the Clark Fork. We can then compare it to other samples that we have tested to determine its toxicity. As of now there is no definite 1
answer as to what caused the “Fish- Kill” in 1984, this experiment is important as it couldlead us to answering this question. Testing these samples will allow us to determine if the
