Study Guide Questions (SGQ):


1.

Write down six of the major aquatic ecosystems
and the major environmental parameters of each.

2.

What are the lessons to be learned from the Aral
Sea story?

3.

Describe the hydrologic cycle, including each of
its three loops (evaporation, surface runoff and
groundwater loops)?

4.

What is the water quality (purity) at different
points in the cycle. Describe tow natural processes
that result in water purification.

5.

What are ways of desalinating water? What are the
disadvantages of this process?

6.

Describe how a Hadley cell works and why
different regions of the world receive different
amounts of precipitation?

7.

Describe how water demands might be reduced in
agriculture,

industry, and households.

8.

Describe the process of “Dead Zone” formation in
the Gulf of Mexico and other natural runoff
locations.

9.

List some nonpoint sources of water pollution.

10.

Describe how bed
load and sedimentation can be a
“pollutant”.

11.

D
escribe the 3 m
ain parts of wastewater treatment:
Preliminary, Primary and Secondary Treatment.
Then describe other final treatments done in state
of the art facilities such as Biological Nutrient
(inorganic) removal and final disinfection
processes.

12.

Describe the 3 com
monly used methods for
treating the raw sludge hazardous by product of
wastewater treatment. What remains hazardous
even after any of these 3 processes?

13.

Wetlands used to be seen as useless swamplands to
be filled in and built upon. Now we realize the
grea
t natural services they provide. Describe some
natural functions they provide which help us.

14.

Contrast the different tolerance requirements for
benthic plants (submerged aquatic vegetation) and
phytoplankton. Give species examples of each.

15.

What is the E
PA’s approach to regulate water
pollution from non
-
point sources using the Total
Maximum Daily Load Model.
