Aquifer

  1. 1. Reported by: Loven S. Getutua
  2. 2. AQUIFER A body of saturated rock which water can easily move. Aquifers must be both permeable and porous and include such rock types as sandstone .
  3. 3. TYPES OF AQUIFER
  4. 4. UNCONFINED AQUIFERS CONFINED AQUIFERS
  5. 5. Unconfined Aquifers Where groundwater is in direct contact with the atmosphere through the open pore spaces of the overlying soil or rock, then the aquifer is said to be unconfined. The upper groundwater surface in an unconfined aquifer is called the water table.
  6. 6. Confined Aquifers Confined aquifers are permeable rock units that are usually deeper under the ground than unconfined aquifers. They are overlain by relatively impermeable rock or clay that limits groundwater movement into, or out of, the confined aquifer.
  7. 7. Unconfined aquifers receive recharge directly from rainfall and surface water infiltrating downward. Confined aquifers are connected to unconfined areas where water can flow in.
  8. 8. Common Questions
  9. 9. Is an aquifer an underground river?
  10. 10. How does an aquifer work?
  11. 11. Why is Groundwater so clean?
  12. 12. How is an aquifer contaminated?
