Great Lakes

On the river I learned that we have a low Biological Oxygen Demand, which is unusual. I don't know if something went wrong in testing or if our water was contaminated. But our Q-Value was 52. The overall Q-Value for the class was 73.779. I was very surprised by this because this means our river's in pretty good shape. I thought our river was trashed and very dirty. My action project can maintain the health of the river by keeping our trails clean and pollution down.

1. The larget Great Lake in Volume is Superior, the smallest is Erie.
2. The most urban lake is Lake Erie, the most rural is Lake Superior.
3. The Lake with the longest shoreline is Lake Huron.
4. We can best manage our ecosystem by doing our best not to pollute the land or air. Everything drains back to the Great Lakes so if we don't pollute our watersheds we will do our best to keep our ecosystem healthy. Also, to manage our waste disposal so it doesn't get into the Great Lakes.
5. 2 Types of pollutants that pertain to my action project are pesticides, since there are many farms around our trails, and pesticides. Everything drains back to our wetlands on our trail.
6. The water rom my house goes into the ground.
7. Runoff water is excess water that will not absorb into the Earth. Runoff water goes into streams, ponds, storm drains etc.
8. Runoff water in the city goes to the same place as the sewer. It shouldn't go to the same place because by going into the sewer it is contaminating perfectly clean water.
9. Sources of pollution in runoff water is the air, fertilizers, pesticides etc.
10. Point Source pollution is leaked from an obvious place, like a factory, while Non-Point Source pollution is leaked from lesser known places, like small backyard spills.
11. A watershed is an area of land where all the water drains to a same place.
