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

43. 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)
