Ground water is an important part of our lives
every day
  • The average person uses 50 to 120 gallons of
    water every day, for drinking, bathing, cooking,
    washing clothes
  • If you live in a home that uses its own well, you
    are also using ground water
  • In Louisiana, there are 11 principle freshwater
    aquifers of which hundreds of millions of gallons
    of water per day are withdrawn from each

7
Using Water In Louisiana
  • In Louisiana, we use 1.6 billion gallons of
    ground water every day
  • About 770 million gallons a day of that goes to
    home wells and public water supply
  • Ground Water Aquifers are permeable, saturated
    zones or rock or sand that contain water
  • For example, the Lafayette area draws ground
    water from the Chicot Aquifer
  • The Chicot and Mississippi River Alluvial
    aquifers account for about 80 percent of ground
    water use in Louisiana, more than 1 billion
    gallons a day

8
Our Concerns About Ground Water
  1. Conservation
  2. Contamination

9
Conservation
  • We do not want to take water from an aquifer at
    such a rate that we exceed its ability to
    recharge
  • Recharge is the term used in describing how an
    aquifer soaks in more water to replace what is
    leaving due to wells or the natural water cycle
  • If that balance is lost, the water table falls

10
What you can do conserve water
  • Turn water off while you are brushing your teeth
  • Dont run the water constantly when washing
    dishes
  • Or, if you have a dishwasher, only run it when
    full
  • Take less time in the shower
  • If you see a leaking faucet, let someone know to
    get it fixed
  • Remember that your toilet is not a trash can,
    dont use it to flush what can be thrown away

11
Contamination
  • Household cleaners can contribute to ground water
    contamination
  • Chemicals you use outside can contribute to
    ground water contamination
  • Litter can contribute to ground water
    contamination
  • Spills of oil or gasoline outside can contribute
    to ground water contamination

12
What You Can Do To Protect Against Contamination
  1. Dont litter, and pick up litter when you see it
  2. Reuse and recycle when you can
  3. Dont pour household chemicals down drains or
    onto ground
  4. When working outside, try to minimize the use of
    chemicals on lawns
  5. If handling chemicals outside, be careful not to
    spill onto ground

13
Worldwide Concern, Not Just Louisiana
  1. 1.5 billion people in world depend on ground
    water for drinking water
  2. Of all the water in the world humans can drink,
    98 percent is stored in aquifers as ground water.
