Active Reading
Section: Water Use and Management
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.
In the space provided, write the letter of the term or phrase that best completes
each statement or best answers each question.
_____ 1. How much water is needed to manufacture a car?
a. 50,000 L
c. 1,000 L
b. 500,000 L
d. 100,000 L
_____ 2. The amount of water used in the world for industry is
a. 500,000 L.
c. 19 percent.
b. vast amounts.
d. 1,000 L.
_____ 3. Water is used in industry mainly to
a. cool power plants.
c. create steam, which is then used
for energy.
b. keep machinery running.
d. clean huge cooling towers.
_____ 4. Water that is returned to a river from a power plant cooling tower is
a. cooler than the river and contaminated.
b. warmer than the river and contaminated.
c. cooler than the river but clean.
d. warmer than the river but clean.

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.
Lawrence River and the Great Lakes, as
well as the city’s proximity to major U.S.
industrial areas and cities.

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.
