2 Page 2: Remediating Water Questions 3 1. Describe one change in farming practices that can reduce the effects of eutrophication. 2. Dead zones are areas in the world's oceans and lakes that are void of life due to low oxygen levels. Explain why dead zones are often located along heavily inhabited coastlines. 3. During heavy rainstorms, sewer systems in some older cities can be overwhelmed with water. This can result in raw sewage being discharged into nearby waterways. What impact might this discharge have on the waterway?

2. Dead zones are areas in the world's oceans and lakes that are void of life due to low oxygen
levels. Explain why dead zones are often located along heavily inhabited coastlines.
3. During heavy rainstorms, sewer systems in some older cities can be overwhelmed with water.
This can result in raw sewage being discharged into nearby waterways. What impact might this
discharge have on the waterway?

4. Explain why the amount of dissolved oxygen in a lake is often considered an indicator of the
"health" of the lake.
5. One strategy to reverse the effects of eutrophication in a pond is to install an aeration system.
This technology bubbles air into the pond and, in doing so, continually stirs up the surface water
so that algal blooms cannot form. Explain how the use of an aeration system reduces the impact
of eutrophication.
