Water pollution is the introduction into fresh or ocean
waters of chemical, physical, or biological material that degrades the quality
of the water and affects the organisms living in it. This process ranges from
simple addition of dissolved or suspended solids to discharge of the most
insidious and persistent toxic pollutants. The presence in water of harmful or
objectionable material in sufficient quantity to measurably degrade water
quality. Next, water pollution is defined as any direct or indirect changes to
the physical properties, thermal, biological, or radioactive which any part of
the environmental release, remove, or put this waste to the detriment of its
usefulness and cause a dangerous situation and harm health, safety and welfare
of the public, or other life such as birds, wildlife, fish and aquatic life and
water plants. The main cause of water pollution is the dumping of garbage from
residential areas along the rivers, the lakes and the sea. Disposal of waste
materials such as garbage, oil, and uncontrollable bowel will cause water
properties change and lead to contamination. For example, the Water treatment
Plant between polluted rivers caused by pig faces around 1980's. Polluted
rivers will flow to the sea and thus lead to pollution of the sea and attitude
of some unscrupulous factory operators remove toxic waste into rivers or the
sea also led to water pollution. Water pollution will affect to human health because
require brain water content in 74%, 75% muscle, blood 82%, 22% bone, tooth 5%,
heart kidney 69% and 82%, Humans can survive for weeks without food, but
without air, will cause dehydration and will die within a few days. Why is
water so important? Water is very important to help the digestion, absorption
and elimination of food eaten. In addition, water helps the excretion of waste
from the intestines and kidneys. Other functions of the water in our body are
to align body temperature 24/7 and provide smooth movement of joints and membranes.
Almost 92 percent of the blood is water. Blood is a transport system that works
'distribute' nutrients throughout the body. While the body secretions and
digestive juices are almost entirely water. Besides that, the digestive system
produces nearly 1.7 litters of saliva each day. Preventive measures is mass
media and electronic media play an important role to raise public awareness
about the importance of river awareness campaign should be conducted through
television, newspapers and the like to bring awareness to the community about
the importance of water in everyday life. By organizing this campaign aims to
inculcate an attitude of love for nature and enforce laws to prevent the
recurrence of pollution this as well as cooperation from the public in order to
reduce incidents occur in our country. If we consider the earth as our own
home, would we foul him? The conclusion, the pollution problem will not be
resolved if there is no self-consciousness in people about the importance of
the environment to human health, the environment clean and protected reflect a
harmonious and healthy society for leading the development of science and
technology. The saying goes "if we pour chemicals into an organism, it
appears as though, by we threw a sack of nuts screws and pegs into the
machinery" Delicate "who ever created’.
