List some
sources of point source and non-point source pollutants.
Why is point
source pollution easier to monitor and cleanup than non-point source
pollution?
How does
‘season’ affect point source and non-point source pollution?
How does water
(precipitation) affect point source and nonpoint source pollution?
Why is water
so easily polluted?
Review the
‘characteristics of water’ from Chapter 3 Matter, Energy and Life.
What is
Atmospheric deposition?
How do
pollutants become ‘airborne’?
What is a
pathogen?
Why are
pathogens the most commonly treated water pollutant?
Where do these
pathogens come from?
What are
coliform bacteria?
What does
‘coliform mean?
What does
‘coli’ refer to?
How does raw
sewage contribute to water pollution?
How is sewage
treated in developed countries (USA, Japan) vs developing countries
(Haiti, Kenya, Cambodia, India, China)?
How are oxygen
content, game fish, and water quality related?
Compare and
contrast the water quality of water with Higo Oxygen content vs Low
oxygen content.
What type
organisms are found in water with low oxygen content?
How does
oxygen get into water?
Oxygen is not
water soluble – what does this mean to the organisms that live in
water?
Compare and
contrast Oligotrophic, dystrophic and eutrophic.
What is
eutrophication?
What is the
role of nitrogen and phosphorus fertilizers/nutrients in
eutrophication?
What effect
does eutrophication have on water quality?
How is Lake
Waco (in Waco TX) affected by eutrophication?
Where do the
nutrients that cause eutrophication in Lake Waco SUPPOSEDLY come from?
Do you agree
with the residents of Waco? Why or Why not?
Where are red
tides common?
What causes
red tides?
At what
environmental concentrations are heavy metals such as lead, mercury,
and cadmium toxic?
What type
damage do heavy metals cause?
Why is it
useful to classify chemicals according to their chemical
characteristics? (see Chapter 3).
List some
Organic and Inorganic chemicals found in water.
Describe the
water quality of California’s dry agricultural valleys.
How does
season affect the water quality of California’s dry agricultural
valleys?
What is
dioxin?
Where does
dioxin come from?
How are humans
exposed to dioxin, and what does exposure cause?
How are
dioxins used by society?
How was dioxin
used in Eastern Europe during the recent elections?
What is
polychlorinated biphenyl (PCB)
Where does PCB
come from?
How are humans
exposed to PCBs, and what does exposure cause?
How are PCBs
useful?
Compare and
contrast the tolerance limits and tolerance range of aquatic and
terrestrial organisms.
What is a
thermal plume?
Where is a
thermal plume?
How are
thermal plumes prevented?
What effect
can a thermal plume have on the environment?
Why? Describe
this in relation to ‘tolerance range’.
What effect
has the Clean Water Act had on surface water pollution in the US?
Describe
California’s laws that regulate air and water pollution.
How do
California’s laws regulating Air and Water pollution affect the rest
of the US?
How do
California’s laws regulating Air and Water pollution affect the
economy of the US?
Relate
California’s laws regulating Air and water pollution to the concepts
of External and Internal costs. (see chapter 23. Economics)
What is a
‘confined animal feeding operation’?
Why are
animals ‘confined’ like this?
What is a CAFO?
List the
different types of CAFOs.
Describe the
different types of pollution associated with CAFOs?
What types of
livestock operations (factories) produce point source vs non point
source pollution?
Compare and
contrast the Causes and Effects of water pollution in first world,
developed countries vs. third world, developing countries.
What are
aquifers?
How are
aquifers polluted?
Why are
aquifers especially susceptible to pollution?
Why are
pollutants so stable in aquifers?
What causes
photochemical reactions?
Name some
cities that use aquifers.
Name some
industries that rely on aquifers.
Where are
these cities and industries located?
Why are oceans
generally not as stressed as freshwater?
Where are
pollution problems located in ocean waters?
Why are these
areas so affected?
Describe the
Exxon Valdez Oilspill that occurred in 1989.
What is the
cheapest and most effective way to reduce water pollution (or any
other type pollution)?
Why is this
the cheapest and most effective solution?
Compare and
contrast this to the ‘dilution is the solution to pollution’ concept.
How can
industry use technology to reduce pollution?
Describe some
of the technology used by industry to reduce pollution.
What are
filters, scrubbers, precipitators?
Describe
primary, secondary and tertiary sewage treatment.
What role do
wetlands play in water pollution?
What is
happening to the wetlands in the US, and around the world?
Why is this
happening?
Should the
government be able to tell wetland owners in the US that they cannot
‘develop’ their wetland and build Businesses, industry, or homes on
the former wetlands?
