2 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 ?
4Water
as a Resource
5Why 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withdrawn.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
8If 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 ?
14SOIL 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
16Problems
- Erosion
- The dislodgement of soil particles
- Causes
- Precipitation
- Wind
- Poor farming practices
- Off-road vehicles
- Strip mining
- Over-active urbanization
- Commercial development
17Problems 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
18Strategies 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 ?
19Mineral 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
23Conclusion
- 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
