Decomposers reaction to polluted Creek water

Sean Brown, Matthew Anderson, Justin Agan


The question that is being asked is “what possible components of the sewage effluent could be affecting the dissolved oxygen…” In order to answer this question we set up an experiment using a variety of pollutants and a decomposer. Each pollutant was put into its own falcon test tube along with water from Dolese Creek. Our results show that some pollutants increase the amount of algae and DO (dissolved oxygen) while others reduce the algae and DO. After the decomposer was introduced the amounts of DO drastically dropped, although after a week some of the oxygen levels rose above our previous measurements.
