Part A. Water Pollution and Water Quality Assessment
Review the concepts of water quality using your course notes in Unit 6, and watch the Nature of Things production Save my Lake
Based on this information and your own independent research, answer the following:
Describe the key differences between oligotrophic and eutrophic waters in terms of their physical, chemical, and biological features (including food web differences). Based on these differences, which of these two conditions is most desirable and sustainable here in Manitoba and why?
Identify five natural and five human generated sources of contaminants that lead to eutrophication of water bodies. Of these, which do you believe is the most challenging to regulate? Why?
Part B. Lake Winnipeg and Watershed Management
If you have not already done so, watch the Nature of Things production Save My Lake
Using the video Save My Lake as your guide, you should note that there are numerous strategies to manage water quality and promote the sustainability of Lake Winnipeg. Based on the video and your independent research, provide answers to the following:
Describe the key features of the Lake Winnipeg watershed that make this lake particularly vulnerable to eutrophication.
Review water chemistry data from 1999 to 2016 for three rivers that discharge into Lake Winnipeg
Outline the general trends in nitrogen and phosphorus concentrations that occurred over the years of the study;
Outline the differences in nitrogen and phosphorus concentration between the three rivers examined in the study;
What factors do you think may have contributed to the variability observed in the data between years of the study?
Based on these results, what recommendations can you make regarding the management goals and priorities for Lake Winnipeg water quality improvements?
Thinking back to the features of the phosphorus and nitrogen cycles, explain how humans have altered the ways these chemicals should naturally move in the environment. What other sources of these nutrients (describe 4) do we need to control as homeowners concerned for their watershed’s water quality and why?
