The document discusses various causes and effects of water pollution. It explains that water pollution occurs when large amounts of pollutants are added to bodies of water, negatively affecting their quality. Common sources of water pollution mentioned include fertilizer and pesticide runoff from farms, chemical dumping from factories, acid rain, and improper disposal of household chemicals. The document also notes that water pollution can contaminate rivers, lakes, and groundwater, and can harm aquatic life and spread diseases.

2. When God created man, He gave
them the ability to think. With
that, man created tools to make
his life easier. We called this
technology. But that
accomplishment comes with a
price. Technology has given us a
lot but it also gave us waste
products that cause pollution.

3. Water pollution takes place when
a body of water is negatively
affected due to the addition of
large amounts of materials to the
water.

4. The overuse of pesticides and
fertilizers on soil can also cause
water pollution. Fertilizers from
farms seep into the soil, then goes
to nearby lakes and rivers. When
this occurs, the fertilizer will
enhance the growth of algae and
fungi in the water causing red tide.
Pesticides that reach rivers kill all
tiny living things in it.

5. The improper way of disposing
chemical wastes form factories
into rivers causes water
pollution. Since these chemicals
are dissolved in liquid, they will
also seep into the ground of
nearby places.

6. Some soils that are acidic become
more acidic due to acid rain. Gases
and particles of sulfur oxide and
nitrogen oxide emitted by the
combustion of fossil fuel combine
with rain and produce acid rain.
When acid rain falls on the ground, it
may dissolve harmful metals from
the soil. Water run-off deposits them
in rivers, ponds, and lakes.

7. All chemicals that are dumped
into the ground will eventually
end up contaminating our rivers,
lakes, and ground water. We
must, therefore, be careful in
disposing of any household
chemical substance like
kerosene, detergent, and
insecticide because these cause
pollution.

8. The common water pollutants are
oil, decaying matter, plastics,
and other solid materials thrown
into the rivers, seas, and oceans.
Waste materials from factories
dumped in the water contain
chemicals that are harmful to
marine life.

9. Oil blocks the oxygen from being
dissolved in the water. It kills
fishes, corals, and
microorganisms living near the
surface of the water. Plastics
clog water passageways.
Detergents and fertilizers contain
chemicals that cause water to
become a good place for algae to
grow and multiply fast.

10. This results in the shortage of oxygen
in the body of water. Fish and other
aquatic life get suffocated and later
die. This gives the water a foul
smell and makes it unsafe for use.
Human sewage thrown into the water
carries diseases. Some diseases
caused by dirty water are typhoid,
dysentery, cholera, and diarrhea.
