What is the purpose of adding chlorine to water during the water treatment process? How is fresh water used in : Industry Agriculture Homes Many areas of the world without adequate fresh water have become habitable because water management projects have diverted water to the area. What type of water pollutant would a parasitic worm be classified as? Where does the majority of pollutants in the ocean come from? What are the requirements of the 1990 Oil Pollution Act? What is the largest watershed in the U.S.? Name an inexpensive way that EVERYONE could help make sure everyone has access to clean, safe water Why are phosphate detergents banned in some areas? What effect do they have on the environment? Water wars between two countries (or states) can escalate when the upstream country (state) builds dams to hold back the water. Preventing future shortages of water needs to focus on: conservation efforts, reducing pollution, and developing ways to produce fresh water. Both thermal pollution and eutrophication decrease the amount of oxygen in the water. Water that is found in lakes, rivers, and streams is called _________________________. A large area of land that is drained by a river is known as a(n) _____________________. 17. An artificial lake created by building a dam is called a(n) ____________________. 18. A(n) ____________________ is an underground rock formation that holds water. 19. An area of land through which water percolates to be stored as groundwater is known as a(n) _________________________. 20. A process that removes the salt from salt water to make fresh water is called ____________________. 21. Water pollution that washes into storm sewers from many places, such as parking lots and lawns, is known as ______________________________. 22. A process by which nutrients increase in a lake while oxygen levels decrease as a result of human activity is known as ______________________________. 23. The amount of space between the particles that make up a rock determines a rocks _____________________. 24. The ability of rock or soil to allow water to flow through it is called ____________________. 25. A method of providing plants with water from sources other than precipitation is known as ____________________. 26. A ____________________ is a structure built across a river to control the rivers flow. 27. The introduction of chemical, physical, or biological agents into water that degrade the water quality is known as _________________________. 28. Pollution discharged from a single source is called _________________________ pollution. 29. Water that contains waste from homes and industry is called ____________________. 30. Suppose that a controversial new dam has been proposed for a river in your state. Name two benefits and two problems that can result from the building of a dam. 31. Desalination is an expensive method of obtaining fresh water. Explain why some countries use this method. 32. Identify five ways that water can be conserved in your home. 33. Give an example of how water is used in each of the following: a. homes b. industry c. agriculture. 34. Describe a law that has been designed to improve water quality. 35. Identify each of the following as either point source or nonpoint source pollution: a. leaking oil tanker b. rain containing air pollutants c. untreated sewage overflow at a wastewater treatment plant d. the litter in storm runoff e. a leaking underground storage tank f. chemical runoff from lawns and golf courses 36. Explain what happens at each step of water treatment listed below: a. aeration b. chlorination c. filtration d. coagulation . c !
