Part 1
1. Where does your drinking water come from, how is it treated, and what residuals are generated? Is the treated water safe enough for consumers, or do you advocate the use of home filters or bottled water? Explain your answer
2. Why must surface water supplies be filtered, but not groundwater supplies? How does this affect decisions related to which water supply to choose?
3. Explain the process of coagulation and flocculation relating to water.
4. Explain the process of filtration systems from waterborne illnesses.
5. What is cholera? How is one exposed to it and where can it be found?
6. Explain the Pump Handle Removal to water treatment and the process of disinfection.
7. What is chlorination? Why are its advantages and disadvantages?
8. Explain the process of Alum Sludge Treatment relating to water treatments.
Part 2
1. Why is biochemical oxygen demand important? How will it affect your work as an environmental professional?
2. In rural areas, wastewater is not typically treated in a centralized wastewater treatment plant. What happens to the sewage in these areas, and who is responsible for it?
3. Why are solids a great concern to wastewater treatments? How are they dissolved in water, and what is the process to remove them?
4. What is biochemical oxygen demand, and how does it relate to dissolved oxygen?
5. What are sanitary sewers, storm sewers, and combined sewer systems?
6. What is the processing of Jetting, when it comes to clearing out amounts of line blockage?
7. What is the process of Flushing, when it comes to sewers.

Part 3
Distribution System and Drinking Water Treatment Report
Resource: City of Kelsey City Drinking Water, Waste Water and Water Conservation Presentation Memo information available through the City of Kelsey Virtual Organizations Portal and the University of Phoenix Material: City Council Reports.
This report outlines the anticipated approach the City of Kelsey will take to fully use its water resources portfolio. The plan must specify the treatment technologies needed for each major water source and the infrastructure and operational needs for the water distribution network.
• Write a 400 - 500 - word document outlining the distribution system and drinking water treatment technologies to be used in the City of Kelsey.
• Include the following in your plan:
o Outline a specific approach for distributing water by addressing each of the following:
• Flows
• Piping
• Water quality
• Flushing
• Water conservation
• Security
• Adequate storage
• Maintenance plan
o Water main break repair
o Fire hydrants
o Fire flows
o Valves
o Cross connection control.
