headaches, backache, indigestion and high blood pressure. (14) fact, a lot of illnesses could
(15) prevented if people drank the necessary amount of water everyday.
VI.. Read the passage carefully and then answer the questions
Water pollution, contamination of streams, lakes, underground water, bays, or oceans by
substances, is harmful to living things.
Water is necessary to life on earth. All organisms contain it; some live in it; some drink it.

Plants and animals require water that is moderately pure, and they cannot survive if their
water is loaded with toxic chemicals or harmful micro-organisms. If severe, water pollution
can kill large numbers of fish, birds, and other animals, in some cases it may kill all
members of a species in an affected area. Pollution makes streams, lakes,. and coastal waters
unpleasant to look at, to smell, and to swim in. Fish and shellfish harvested from polluted
waters may be unsafe to eat. People who ingest polluted water can become ill, and, with
prolonged exposure, may develop cancers or get children with birth defects. The major water
pollutants are chemical, biological, or physical materials that degrade, water quality.
Oil and chemicals derived from oil are used for fuel, lubrication, plastics manufacturing, and
many other purposes. These petroleum products get into water mainly by means of
accidental spills from ships, tanker trucks, pipelines, and leaky underground storage tanks.
Many petroleum products are poisonous if ingested by animals, and spilled oil damages the
feathers of birds or the fur of animals, often causing death. In addition, spilled oil may be
contaminated with other harmful substances.
Chemicals used to kill unwanted animals and plants may be collected by rainwater and
carried into streams, especially if these substances are applied too lavishly. Some of these
chemicals are biodegradable and quickly decay into harmless or less harmful forms, while
others are non-biodegradable and remain dangerous for a long time.
Heavy metals, such as copper, lead, mercury, and selenium, get into water from many
sources, including industries, automobile exhaust, mines, and even natural soil. Like
pesticides, heavy metals become more concentrated as animals feed on plants and are
consumed in turn by other animals. When they reach high levels in the body, heavy metals
can be immediately poisonous, or can result in long-term health problems similar to those
caused by pesticides and herbicides. Hazardous wastes are chemical wastes that are toxic,
reactive, corrosive, and ignitable. If improperly treated or stored, hazardous wastes can
pollute water supplies. In 1969 the Cuyahoga River in Cleveland, Ohio, was so polluted with
hazardous wastes that it caught fire and burned.
