  1. Water ConservationPart A

  2. 1. Residential Water Use • 14% of water use • The average American uses 140-170 gallons of water per day.

  3. Questions • Which takes up more water: shower or bath? • Is it ok to just wash a few things in the washer? • What does your dishwasher use to clean dishes besides soap and water?

  4. Hard water • Contains nutrients which taste good • Leaves stains on surfaces and clothing

  5. Soft Water • Soapy feeling • Leaves no residue • Made through a water softener

  6. 2. Agricultural Water Use • 67 % of fresh water use in the world Ways to conserve: • Drip irrigation • Irrigation ditches • Water in the evening

  7. Fact of the Day • Eat less meat. According to the U.S. Geological survey, it takes 2,607 gallons of water to produce a single serving of steak and 408 gallons for a serving of chicken. A handful of almonds requires only 12 gallons to grow, rice needs 36 gallons, and lettuce and potatoes need only 6 gallons each.

  8. 3. Industrial Water Use 19% of water used in the world. Water is used to manufacture goods, to dispose of waste, and to generate power. • 500,000 L required to make a car • Most is used to cool power plants

  9. Water Use in the world

  10. Water management projects • Dams • Water canals • Reservoirs • Pipelines

  11. Desalination • Removing salt from water • Done using reverse Osmosis

  12. Pros • Fresh Water! • GE commercial

  13. Cons • Water Quality • Energy Use • Concentrate Disposal • Overall Cost

  14. Abu Dhabi, United Arab Emirates

  15. Facts • Abu Dhabi has the highest consumption of water in the world at 550 liters per capita, compared with 85 liters in Jordan, and is facing a water crisis of such magnitude that it will not be able to sustain current levels of use for more than 50 years.

  16. Xeriscape • ‘Dry landscaping’ using little or no water in landscaping • One way is to plant things that are natively found in Utah

  17. Native plants to Utah • Gamble Oak Utah Juniper • Sage Brush Prickly Pear • Quaking Aspen Pinion Pine • Cottonwood Heartleaf Arnica • Aster

  18. Water Fountains- are they a waste of water?

  19. Genetic Engineering? • Tomatoes in salty irrigation

  20. Desert Wars • Las Vegas vs. Farmers • Both need water, who needs it the most?

  21. Water PollutionPart B

  22. Point source pollution • Pollution discharged from a single source

  23. Nonpoint source pollution • Pollution that comes from many different sources. • Chemicals added to roads, water runoff, pesticides, fertilizers, feces from livestock, acid rain, soil runoff, and oil and gasoline

  24. Wastewater • Wastewater is used water. • Human waste • Food scraps • Oils • Soaps • Chemicals • In homes, this includes: water from sinks, showers, bathtubs, toilets, washing machines and dishwashers.

  25. Logan Treatment Center

  26. New Technologies

  27. Artificial Eutrophication • Humans causing a buildup of nutrients (nitrogen) in a body of water that produces harm. (algae growth)

  28. Salton Sea

  29. 1. Thermal Pollution • Pollution caused by the changing of temperature of a body of water affecting the organisms that live there

  30. 2. Groundwater Pollution • Pesticides, herbicides, and chemical fertilizers

  31. Love Canal, Niagara

  32. 3. Garbage pollution • Oil spills • Cruise ship garbage

  33. Bikini Atoll • 1954 – atomic bomb

  34. Biomagnification • The accumulation of pollutants increases with more consumers

  35. Acid Rain Moisture in the air with high amounts acids that cause damage.

  36. Water Pollution Diseases • Cholera, Typhoid, Schistosomiasis, Dysentery

  37. 4 million children die each year from diarrhea

  38. Oil Spills • 1989 Exxon Valdez and 2010 BP Gulf • 10.9 million gallons 205 million barrels

  39. HELP • Ways we are trying to help!

  40. Education

  41. Pollution regulations
