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 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)

S

Use a diagram to show the important

role that Aquifers play in our water

supply
