  • Our Objectives

We will describe the processes relating to
Water Soil Minerals We will also
consider Potential adverse environmental
impacts due to the use of current and future
resources
3
  • What is a Resource?
  • A material source of fresh water, a mineral
    deposit, or other substances that occurs in a
    natural state and has economic value.
  • The word resource was derived from the Latin
    word resurgere, meaning to rise
  • Conditional Resources
  • Sub-economic Resources
  • Hypothetical Resources
  • Speculative Resources
  • Now lets talk about Water ?

4
Water
as a Resource
5
Why is water important?
  • All animals including humans need fresh water to
    survive.
  • At a basic level, everything we eat has some
    water in it.

6
  • Where do we find fresh water ?

Lakes
Rivers
Snow Pack
Icebergs
These sources are commonly known as Surface
Water
7
  • Another source of fresh water is found
    underground
  • Groundwater is where most of our fresh water is
    withdrawn.
  • Sub-Surface Aquifers/Reservoirs
  • Confined
  • Unconfined Tends to be the most polluted
  • The filling of Aquifers are influenced by
  • Porosity
  • Permeability

8
If the total supply of water on the planet war
represented by a fifty-five gallon drum, then
Ocean
Ice Caps
All Rivers
Atmosphere
Groundwater
Freshwater
Soil Moisture
9
  • Once the resource of Water is located...
  • Its uses are then categorized.
  • Consumptive Use
  • No Re-Charge
  • Non-Consumptive Use
  • Artificial Natural Recharge

10
  • Water use in the United States
  • 48 - Thermoelectric power
  • 34 - Irrigation (water for growing crops, golf
    courses, etc.)
  • 11 - Public Supply (water delivered to our homes
    and businesses by water departments)
  • 5 - Industrial (Manufacturing, making of
    goods, etc.)
  • 2.9 Commercial (restaurants, pizza houses,
    ice-cream parlors, etc
  • Domestic (drinking water, bathing, preparing
    food, etc.)

11
  • So, If we take the Water from the ground and do
    not replace it What can occur?
  • Sinkholes

12
  • As the world population increases.
  • So does the demand for this resource.
  • The evidence suggests resource shortages for the
    future as well as other hazardous events like
    sinkholes and/or subsidence.

What can we do ?
13
  • Practice Conservation
  • Limit water waste in the home.
  • Water lawns in the morning.
  • Avoid traditional lawns and lean towards ground
    covering.
  • Change irrigation habits.
  • Shifting crops where rain is abundant.
  • Reduce water transfer through open ditches to
    limit evaporation.
  • Interbasin Transfer of Surface Water
  • Movement of water from one region to another.
  • Desalination - Purification to make water usable.
    (5x more costly)
  • Filtration
  • Distillation

Now lets talk about Soil ?
14
SOIL AS A RESOURCE
  • What is Soil ?
  • Engineers call soil anything they can move
    without blasting.Jeff Tolhurst

15
  • What We Use Soil For
  • Agriculture
  • Natural and semi-natural vegetation
  • Microscopic organisms domain
  • Habitat
  • Water control and distribution
  • Building and construction
  • Archeology

16
Problems
  • Erosion
  • The dislodgement of soil particles
  • Causes
  • Precipitation
  • Wind
  • Poor farming practices
  • Off-road vehicles
  • Strip mining
  • Over-active urbanization
  • Commercial development

17
Problems Continued
  • Topsoil the rich organic top layer- is lost,
    which leads to reduced ability to farm
  • Sediment deposition run off water that carries
    particles into existing bodies of water, which
    leads to loss of water quality
  • Sediment is currently classified as a pollutant
  • 750 million tons enters lakes and streams
  • Decreases water quality and may harm wildlife
    even worse when sediment contains toxic residue
    from agricultural development
  • Coho Salmon migration and mating processes
    impeded because sediment smothered the gravel
    beds theyre now on endangered species list

18
Strategies for Reducing Erosion
  • Land Use Planning Reducing the velocity agent
    while also protecting the soil from its effects
  • Leaving stubble in the fields after a crop
    harvest, planting cover crops in off-season, and
    in between crops
  • Wind damage can be slowed by planting hedges,
    rows of trees, and low fences
  • Sediment pollution prevention hay bales and
    wattles placed at bottom of hills or
    construction/agricultural sites
  • Off-road vehicles restricted only to prescribed
    trails
  • Urban construction sites clear the land in
    stages, leaving less time for bare soil to be
    exposed

Lets move our attention to Minerals and Rocks ?
19
Mineral and Rock Resources
  • Ore Deposits
  • Types of Mineral Deposits
  • Examples of Mineral and Rock Resources
  • Metals
  • Iron
  • Aluminum
  • Copper, Leads, Zinc, Nickel, Cobalt, ECT.

20
  • Nonmetallic Minerals
  • Sulfur
  • Halite (rock salt)
  • Rock Resources
  • 1.1billion tons sand and gravel used in
    construction 2002
  • 1.6 billion tons crushed rock used for fill and
    other
  • 30 million tons quartz-rich sand used to make
    glass

21
  • Iron is needed for the blood.
  • Magnesium is also needed for a healthy body,
    specifically contributing to bone structure.

22
  • U.S. Minerals Supply and Demand
  • Top Production Consumption Totals of 2002(In
    Metric Tons/Year)
  • Metals
  • Iron .......50,000, 56,000
  • Aluminum ..2,700, 6,400
  • Silver . 1,470, 5,340
  • Copper . 1,450, 2,700
  • Non-Metals
  • Salt ..43,900, 50,200
  • Clays .. 40,700, 35,900
  • Phosphate 35,800, 37,700
  • Minerals for the Future Some Options Considered

23
Conclusion
  • Today we have discussed the recourses of water,
    soil, and minerals
  • We are consuming more than we are producing
  • We need to conserve, find new methods of use, and
    new resources
