  1. Water Water Everywhere! but not a drop to drink ? Dr. Ruthanne “Rudi” Thompson UNT Associate Professor Biology & Environmental Science Principal Investigator: Dallas EEI

  2. Water and Life Thompson The amount of water is stable. It is found in different forms. It is necessary to sustain all forms of life.

  3. What does this mean? Thompson • There are approximately 326 million trillion gallons of water on Earth • 98% is in the oceans • 1.6% is in polar ice caps and glaciers • .36% is groundwater • .036% is in lakes and rivers • remaining .004% is in clouds, living things, in our foods, bottled water, etc.

  4. Life and Water Thompson Population is NOT stable. Urbanization alters the natural water cycle. It is possible to run out.

  5. What the Data Tells Us Thompson • Average Population growth rate = 1.17% • average of 82 million people per year • Current world population 7+ billion • Expected Population of 9+ billion by 2050

  6. A Growing Gap Thompson Average family of 4 = 400 gallons a day of which 70% is used indoors

  7. Remediation Thompson • "In the end, we will conserve only what we love, we will love only what we understand, and we will understand only what we are taught.“ • Baba Dioum • Dallas Environmental Education Initiative • www.dallaseei.org • Beginning 2006 • In class hands-on, inquiry-based water conservation lessons • 45,000+ students • 98.7% commitment to water conservation

  8. Results Thompson • 2008-2010 – largest decrease in water use occurred in Zip Codes that received education (p<.001, ANOVA) • 2011 – Education zip codes used statistically significantly less water when compared to control zip codes (p<,001, t-test) • Twice is nice but thrice?? • Ongoing research
