  1. Daily Review #2 • What two factors affect groundwater? • How does the pumping out of water in a well effect the water table and why? • What is the Ogallala Aquifer and why is it important? • What do discharge and recharge mean? End

  2. Surface Water • Lakes, rivers, streams, etc. • From precipitation • Runoff • Infiltration, eventually • Watershed or Drainage Basin • Divides • Headwaters • Colorado is a headwater state

  3. Streams (Rivers) • Definition • Groundwater meets surface and runoff • Flow downhill • Carries sediment • Faster water = larger sediment • Agent of erosion • Tributaries • Creeks

  4. Landforms made by Erosion • Stream channel • Meander • Ox bow lakes

  5. V-shaped valley • Waterfalls • Deltas • Floodplain • Good farmland

  6. Daily Review #3 • How do rivers and streams form? • Define watershed, delta, ox bow lake, floodplain and tributary and divide • Why is Colorado considered a headwater state? • When it rains in Parker, where does the water eventually end up? End

  7. Water Pollution • Types • Sediment • Nutrients/chemicals • Pathogens • Point • Nonpoint • Fertilizer • Algal blooms • Eutrophication • Erosion

  8. Fixing Pollution • Clean Water Act (1972) • Reduce, reuse, recycle • Limit fertilizers • Limit erosion • Changes in agricultural practices • Barriers during construction, mining, etc. • Decrease usage

  9. Ocean Issues • Why is the ocean important? • Ocean issues • Trash dumping • Sludge dumping • Oil spills • Excessive fertilizer use • Coral bleaching

  10. Desalinization • Process • Distillation • Reverse osmosis • Energy intensive

  11. Urban Water • Extraction • Groundwater • Decreased infiltration • Surface water • Water rights • Distribution • Treatment • Filtering • Biological agents • Sludge disposal • Reuse • Use of grey water
