CEE 320 Quiz #7 Environmental Engineering F 19 March 2010 PLEASE WRITE YOUR NAME ON THE BACK Quiz #7 1. LAKE WATER QUALITY Compare and contrast lakes classified as oligotrophic, mesotrophic, eutrophic, and hypereutrophic, in terms of productivity, clarity, and oxygen levels. Oligotrophic: low productivity, very clear, high oxygen Mesotrophic: medium productivity, medium clarity, medium oxygen levels Eutrophic: high productivity, low clarity, low oxygen levels Hypereutrophic: very high productivity, very low clarity, oxygen levels may drastically shift between high and low 2. PHOSPHORUS VS OTHERS Recall our discussion in class about the macronutrients that are essential for building cells

Unformatted text preview: (CHNOPS). Describe the major difference between the phosphorus cycle and other nutrient cycles, in this context. What are the ramifications for lake water quality with respect to eutrophication? The phosphorus cycle does not have a gaseous phase. If phosphorus is the limiting nutrient, it may cause eutrophication by providing the nutrients required to build cells; it can be difficult to remove it from a lake because it has no volatile form and thus requires physical measures to remove it (inflows/outflows/dredging)....
