  1. Water Scarcity: Tomorrow’s Problem Alex Hall Shane Schwikert Mike Jen

  2. What We Will Address • What’s the Problem? • Hypothesis • Relevant Research and Findings • Future Concerns • Preventative Measures • “Take Home Message”

  3. Hypothesis If global water scarcity issues are not addressed today, it will greatly limit future sustainability. (www.watsys.sr.unh.edu/.../girl-water_sm.jpg)

  4. Introduction • Effects of water scarcity not felt everywhere • However, one billion people lack access to clean drinking water (1/6 world population) (www.nadir.org/.../txt/2002/waterscarcity.htm)

  5. Introduction Cont’d • Water is not being recycled efficiently • Water pollution rate is higher than natural purification rate • Only 0.009% of earth’s water is readily available for use (Al-Sofi, 1994)

  6. Results and Discussion • Lack of abundant usable water creates tension among countries • Many countries are at a geographic, water-deprived disadvantage • Treaties that do exist are localized and generally ineffective

  7. Results and Discussion

  8. Results and Discussion Graph with 0% recycled water

  9. Results and Discussions Graph with 70% recycled water

  10. Implications (www.infoforhealth.org/pr/m14/fig5a.gif)

  11. Implications Cont’d • Many global implications • Health Care • 10,000-20,000 children killed by water-related diseases everyday • Environmental • 20% of all freshwater fish species are now threatened or endangered (Gleick, 2001)

  12. Implications Cont’d (www.waternunc.com/.../waterscarity2025.jpg)

  13. Solutions • Implement efficient recycling/reclaimation system for irrigation water • 3.4 Billion gallons drinking water saved, enough to support 31,000 families • Only 2.3% wastewater is currently recycled • $26 Million could be saved in Los Angeles County in water transportation costs if efficient recycling implemented (Arrandale, 2002)

  14. Our Solutions • Develop and mandate more efficient household water heaters • Heated Pipes • Better Insulation throughout system • Effects: Conservation, lower heating costs (Shane’s Basement)

  15. Our Solutions • Compose new multinational treaties to address: • Water sharing • Eliminating unequal distribution • Allocate with regard to aridity of region

  16. Conclusion • Consumption continues to steadily increase while water remains limited • Must be addressed for future sustainability • More than one solution is needed to solve problem (http://www.umweltbundesamt.de/wah20-e/grafik/Tafel1_2.jpg)
