what are some of the greatest challenges associated with our water supply

What are some of the greatest challenges associated with our water supply?

EnvironSci book p.293 - 298

what are some of the greatest challenges associated with our water supply1
What are some of the greatest challenges associated with our water supply?
  • Access to Groundwater (Aquifers are recharged by Surface water)
  • Transpiration (Cottonwood & Willow trees suck up and evaporate water)
  • Competition for Use of water supply (agriculture, drinking water, septic system)
  • Agriculture Nitrates & Phosphorous (from fertilizers)
  • Urbanization (population growth in cities draws more groundwater)
use a diagram to show the important role that aquifers play in our water supply

Where does the majority of YOUR drinking water come from?

  • Study the Hawaiian Island terrain maps with your group.
    • http://www.wrcc.dri.edu/precip.html
  • Then study the Avg Precipitation maps over the islands.
    • Q. What patterns can you identify in regards to precipitation and terrain?

El Nino
  • Where does the name “El Nino” come from?

Normal Pacific Ocean Currents

But every 4 - 12 years…
