    Water Part 2: notes and WQI

    quiz 11.12.19

    1. If you became a vegetarian, how would this preserve water?
    2. What two things are happening to the Ogallala aquifer and why?
    3. As the Himalayan ice pack disappears, what will be the impact on Asia?
    4. How would a sewage discharge in a river impact the DO?
    Notes:
    Climate change will raise sea levels
    Even a rise in ocean levels of a few meters will mean saltwater intrusion into the Pearl River delta, where most of the rice for Asia is grown:
    Same for Florida, Mississippi, Louisiana, parts of the Amazon, Bangladesh, and any area where there is a delta like the Nile River Delta in Egypt.

    Recall: Energy->Water->Food-> Culture?
    Here's how you create potable (drinkable) water from seawater:


    Note how much energy is needed. Some countries are considering nuclear power for this.
    Conservation:
    You may see a question very much like this on the AP exam in May:

    You will see these calculations again soon with energy.
    TCO is total cost of ownership, and should be negative
    ROI is your return on investment, the amount of time until your invested money is paid off, the shorter the better
    Lifetime: the lifespan of the project (washing machine, solar panels, etc.)

    Whitewater, greywater, blackwater...

    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).

    Clues:

    High turbidity decreases DO, as does high temperature

    Metals increase conductivity and are usually acidic

    Nitrates and phosphates lead to dead zones

    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
