What are some of the greatest challenges associated with our water supply? EnvironSci book p.293 - 298

Slide 6

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)

Slide 7

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?
