11.2 Water Use and Management Active Reading
Read the passage below and answer the questions that follow.
Industry accounts for 19 percent of water used in
the world. Water is used to manufacture goods, to dispose
of waste, and to generate power. The amount of water
needed to manufacture everyday items can be astounding.
For instance, nearly 1,000 L of water are needed to
produce 1 kg of aluminum, and almost 500,000 L of water
are needed to manufacture a car. Vast amounts of water
are required to produce computer chips and
semiconductors.
Most of the water that is used in industry is used to
cool power plants. Power-plant cooling systems usually
pump water from a surface water source such as a river or
lake, carry the water through pipes in a cooling tower,
and then pump the water back into the source. The water
that is returned is usually warmer than the source, but
it is generally clean and can be used again.
IDENTIFYING MAIN IDEAS
One reading skill is the ability to identify the main idea of a
passage. The main idea is the main focus or key idea. Frequently, a
main idea is accompanied by supporting information that offers
detailed facts about main ideas.

8. water table; saturated
9. A water table has peaks and valleys like
the land above it. It is not flat like a dining
table.
10. A water table in a wet region is likely to
be near the surface of Earth, and springs
may flow out of the ground. A water table
in the desert may be far below Earth’s
surface.
11. It flows downhill. Underground peaks and
valleys cause this movement.
12. The water table is near the surface of
Earth.

They are all located near water.
Answers may vary but should involve
proximity to waterways such as the St.

Eutrophication occurs naturally; artificial
eutrophication has the same results as
eutrophication but is caused by human
activity.
humans
inorganic plant nutrients enter the water
from sewage and fertilizer runoff
fertilizer from farms, lawns, and gardens
phosphates in laundry and dishwashing
detergents
phosphorus
Most of the dissolved oxygen in the water
is used as the algae dies and decompose,
so the fish suffocate.
