Description complete the lab below UNFORMATTED ATTACHMENT PREVIEW General Environmental Science I ENV 122 LAB: Virtual Landfill and Wastewater Treatment Tours Name: ______________________ There is no lab quiz associated with this lab. You will be taking virtual tours of a landfill, a waste to energy plant, and a wastewater treatment plant. The correct answers come from the videos. Other answers will not be accepted and will lose you points. Please watch the video at the following link to get a virtual tour of a landfill and answer the questions about your virtual tour: https://youtu.be/P_CNawTetqw 1. Name three things a modern landfill is designed to protect 2. How much of the landfill site is actually the landfill? List at least three things we find on the landfill site in addition to the landfill itself. 3. What is a cell in the context of a landfill? 4. What is the purpose of the cell liner? 5. What is the working face? 6. What is the purpose of the liner that is used to cover the working face at the end of each day? 7. How is odor minimized at the landfill and where does the water they use come from? 8. What are the two main by-products produced by the landfill captured in the wells? 9. What happens with the methane captured at the landfill? 10. How much energy can one cell generate? 11. What is the name for the liquid that is produced by the decomposition of trash? 12. How is leachate formed and where does it go once it leaves the landfill? 13. How long can a landfill be monitored after it is closed? 14. What are some things that closed landfills have been turned into? In the Northern Virginia area, most of our solid municipal waste is sent to COVANTA, a waste to energy facility. Watch this brief video and answer the questions about COVANTA: https://www.youtube.com/watch?v=-KmTbHInScw 1. How are unacceptable items identified? 2. How is the waste disposed of at COVANTA and how long does it take for a typical hopper worth of waste? 3. What are two ways that the steam that is generated is used? 4. How much electricity can be generated per ton of waste? 5. By how much is the volume of waste reduced by the end of the process and what is done with the ash? 6. How is air pollution controlled at the Covanta facility? Now you will take a virtual tour of the Fairfax County wastewater treatment plant using the following link and answer the questions: https://www.youtube.com/watch?v=6uzFmUGihMI 1. How much water is typically cleaned every day at the plant? How many swimming pools is that? 2. What is the first step in water processing once the water reaches the Noman Cole plant? What happens here and where is this waste sent? 3. What is the second step in the processing of the water? What is removed during this step? 4. What is the issue with fat, grease, and wipes that go down the drain? What should you do with these things? 5. Where does the water go after the primary clarifiers (settling tanks)? 6. What happens during secondary treatment (what types of organisms are important and what are they removing?) 7. What are the two zones of secondary treatment? 8. Where does the water go after the ASTs and what happens here? 9. What can harm the important microorganism populations of the wastewater treatment plant? 10. Where does the wastewater go after secondary treatment? 11. What does advanced treatment involve? 12. What do we call the small colonies of bacteria that form on the plastic? And what is their food source? 13. How is phosphorus removed in the tertiary settling tanks? (what is the name of this process? what chemical is used and what happens to the phosphorus and bacteria?) 14. How is the water disinfected before it is discharged today? How was it initially disinfected? 15. How long does it take from the time wastewater enters the plant until it is fully treated and discharged? 16. What does the Water Reuse project use reclaimed water for and why is it important? 17. How can you help protect the environment according to the video?  Purchase answer to see full attachment User generated content is uploaded by users for the purposes of learning and should be used following Studypool's honor code & terms of service.
