  1. Groundwater’s Importance - % available freshw - % drinking water - % irrigation - % industrial Problems with using Groundwater Movement of GW - porosity v. permeability - aquicludes & aquifers Wells - drawdown & cones of depression - aresian wells – what 2 conditions must exist? How does water move underground? Groundwater’s Geological Roles - solvent (explain) - equalizer (explain) Distribution of GW - def. Water Table - zones of saturation & aeration

  2. Groundwater’s Downside - should it be treated as NONrenewable? - Ogallala Aquifer – overuse - subsidence Central Valley, CA - what’s our LOCAL example? Contamination – describe fully 6 ways GW can be contaminated. How to fix it? Groundwater’s Masterpieces Cavern – how formed? Staladtites v. stalagmites Karst Topography – what is it? where does it occur in TX? Geysers – what are they? how do they form? Where are they found in North America?
