Water pollution
* 1. Water is a chemical essential for all known forms of life on earth to date, but not on another planet. Water can be either solid (ice), liquid (water) and gas (water vapor). Water is the only substance which is naturally present on the surface of the earth in his being the third. Poor water management can cause water shortages, monopolisation and privatization and even spark conflicts. (Wikipedia). Water
is a chemical substance with chemical formula H2O: satumolekul water
consists of two hydrogen atoms covalently bonded to one oxygen atom. Water
is colorless, tasteless and odorless at standard conditions, ie at a
pressure of 100 kPa (1 bar) and temperature of 273.15 K (0 ° C)

* 3. Water
pollution is the event of the entry of substances, energy, elements or
other components into the water, interrupted water sehinggakualitas
marked with perubahanwarna, odorless and tasteless so water is not pure

typically called when tergangguoleh anthropogenic contaminants and when

* 6. The
characteristics of water polluted / contaminated sangatbervariasi
because it depends on the type of water danpolutan contained therein. However cirriyang most easily recognized are: 1. Berbau2. Berwarna3. Berasa4. Baracun
* 7. To determine the pollution of water can be observed denganterjadinya changes include: 1. PH value, acidity and alkalinity of the normal pH of the water is pH 6-8. If too low, it can cause korosif.2. Temperature If the temperature is too low, the water will feel cool and even cold to icy. Vice versa, however, always had regular water temperature 0o size fits celcius.
* 8. 3. The color, smell and taste • Water Color polluted usually different from the normal color (clear and transparent). •
The smell usually depend on the water source, can be caused by
chemicals, plants and aquatic animals that live both Maup death (such
as a fishy odor and foul). • Sense of normal water has no taste, except the salt in the water laut.4. The amount of oxygen in the air5. Patogen6 microorganism contamination. Content minyak7. The content of heavy metals
* 9. Various
kinds of polluted water sources, among others: • Industrial waste •
Agriculture • House rangga There are several types of pollutants which
can damage the waters, namely: • Contain germs • Need lots of O2
(Oxygen) to dissociation (so lack of O2 during the process decomposition)
• Organic chemicals from agricultural fertilizer industry • Waste •
Materials that do not sediment (sediment) • The materials that contain
radioactive and heat
* 10. Germs from the air pollution containing bersifatberacun substances and radioactive materials which could harm manusia.Kenapa? Because pollutants requires a lot of O2 content, but if the shortage, there will be changes warnadan decay. Due
to the decomposition of the pollutants tidakakan perfect that arose
air.Permasalahan pollution on water pollution is the largest in
disposal sampahdisembarang place. For example: garbage disposal at muarasungai, sea, or a small home-based gutters. This could menimbulkanpenyakit.Contoh such events in Japan. Substances

from disabilities
* 11. Consequences caused by water pollution, among others: 1. Disruption of aquatic organisms due to the reduced oxygen content (O-2) 2. Explosion of algae and plants air.3. Perairan4 basic silting. In the long run are cancer and birth cacat5. Due
to the excessive use of pastisida appropriate than killing pests and
disease, it also kills insects and is especially useful maskhluk

* 12. As a result of the emergence of polluted water according to the wikipedia site, among others: 1. May cause banjir2. Erosi3. Air4 resource shortage. Can make penyakit5 sources. Land longsor6. Can damage the river ecosystem
* 13. 1. Placing an industrial area or a factory far away from residential areas or perumahan2. Disposal of industrial waste regulated so that does not pollute the environment or ekosistem3. Supervision of the use of the types of pesticides and - other chemicals that can cause pencemaran4. Extending the green movement
* 14. 5. Action against pollution lingkungan6 behavior. Bring awareness to the community about the meaning of the environment so that people are more loving environment. Intensification of agriculture
