It is a common practice, particularly in the Western United States, to treat wastewater to a very high level, and then inject it back into ground, where it can be used to replenish the groundwater table. Suppose that you are managing a large water district and a local city council member wants to use secondary treated wastewater instead of tertiary treated wastewater to recharge the groundwater basin.

Write a 2- to 3-page paper in which you:
1.Describe the waste water treatment process including primary, secondary and tertiary treatment methods.
2.Compare and contrast the secondary water treatment methods to tertiary water treatment (also known as advanced or final water treatment) methods in terms on their impact on water quality. In your answer, consider that there are multiple secondary water treatment methods and multiple tertiary water treatment methods.
3.Discuss the appropriate uses of reclaimed water. Describe at least three examples.
4.Explain whether you would recommend secondary treatment or tertiary treatment for the groundwater recharge, if this water were to end up being used for drinking. Explain the rationale of your choice.
Precision: Each of the questions of the assignment is specifically addressed in the paper. Your paper compares and contrasts the secondary water treatment methods to the tertiary water treatment methods, in the context of the wastewater treatment process. Your paper discusses the appropriate uses of reclaimed water. In your paper, you explain whether you would recommend secondary treatment or tertiary treatment for the groundwater recharge, if this water were to end up being used for drinking.
