    Water

    Recall:
    Energy->Water->Food->Culture
    Where is the water?
    How does it get there?



    Aquifers:



    Huge aquifer-note recharge time is in centuries, pesticides in NE

    Water diversion (e.g. rivers)

    Two critical issues for China:
    Pearl river delta and salt intrusion (sea level rise)
    Vanishing Himalayan Glaciers (no farming in western China):

    Glaciers are the water towers for Asia...
    Rivers impacted:
    Ganges, Yangtze, Yellow, Mekong, Brahmaputra, Irrawaddy, Indu, Salween,




    Aral Sea (asia minor)

    Water disputes:

    Water Pollution categories:

    Pollutant list:


    Nitrate levels (note farming regions):

    Why is there a hypoxic zone there?

    Biochemical Oxygen Demand (BOD):
    Better diagram:

    Note that temperature changes DO (dissolved oxygen) content, so does physical agitation (aeration).

    Water Quality Index:

    See also point source and non-point source pollution (from Poisoned Waters video, remember the Deer?)

    Important: cooler water holds dissolved oxygen better (fishermen know this, so do the fish).

    Water Quality Lab:

    Lab samples

    1. Post waterfall
    2. Post power plant
    3. Everglades close to ocean
    4. Post sewage plant
    5. Best fishing spot
    6. Mine tailings runoff
    7. Snow melt river
    8. Mississippi river
    9. Chesapeake river
    10. Flood after monsoon rains
    11. Golf course runoff
    12. Eutrophied lake
