Resources and Water pollutants.

Water pollution in the water occurs when there are different kinds of substances or conditions (eg heat) that can lower water quality standards that have been determined, so can not be used for specific needs. A source said contaminated water not only because it is mixed with contaminants, but if the water is not in accordance with specific needs, for example a source of water containing heavy metals or bacteria containing the disease can still be used for industrial needs or as power plants, will but can not be used for domestic needs (drinking water purposes, cooking, bathing and washing).

Sources of Water Pollution causes

There are several causes of water pollution, among others, if water is contaminated with air pollutants such as household garbage, industrial waste valleys, the remnants of fertilizers or pesticides from agricultural areas, hospital waste, waste manure, particulate-solid particulates of forest fires and erupting volcanoes or erosion of sediment places in its path.

Water contaminants

Basically, water contaminants can be grouped into:

a) Waste is in the process that require oxygen penguraiannya waste containing organic compounds, such as junk food industry, sugar industry waste, household garbage (food scraps), human waste and animal waste, tumbuhtumbuhan and dead animals. To sampahsampah the decomposition process requires oxygen, so if tersbut waste contained in the water, then water (water source) will be lack of oxygen, the fish and organisms in the water will die of oxygen deficiency. Also decomposition of waste containing protein (animal / vegetable) will produce H2S gas foul-smelling, so the water unfit to drink or to bathe.

C, H, S, N, + O2? CO2 + H2O + H2S + NO + NO2

b) Material pollutants cause disease, ie contain contaminants that such viruses and bacteria coli bacteria that can cause digestive tract diseases (dysentery, cholera, diarrhea, types) or skin disease. These pollutants come from household waste, hospital waste or from waste animal / human.

c) inorganic pollutant materials / minerals such as heavy metals like mercury (Hg), cadmium (Cd), Lead (pb), copper (Cu), inorganic salts. Contaminants of heavy metals that enter the body through food and usually can be accumulated in organs such as kidneys, liver, spleen other digestive tract that interfere with the function of these organs.

d) Raw organic pollutants that can not be broken down by microorganisms of organic compounds derived from pesticides, herbicides, polymers such as plastics, detergents, synthetic fibers, industrial waste and waste oil. These contaminants can not be destroyed by microorganisms, so it will be piled everywhere and can disrupt the lives and welfare of living things.

e) Material contaminants of food plants such as nitrate compounds, phosphate compounds can cause the growth of algae (seaweed) so rapidly over the surface of the water. Also water will disrupt ecosystems, and fish kill organisms in the water, because levels of oxygen and reduced sunlight. This is due to oxygen and sunlight needed organisms in the water (aquatic life) is blocked and can not enter into the water.

f) Material of radioactive contaminants, can cause cancer, damage the cells and other tissues. These pollutants come from nuclear plants and waste from nuclear experiments other.

g) material in the form of sediment contaminants / sediments such as dirt and mud from erosion on the riverbank or particulate-particulate solid / lava is blown by the erupting volcano, causing the water becomes turbid, the entry of reduced sunlight, and water is less able to assimilate waste.

h) of pollutant material conditions (eg heat), derived from waste power plants or industrial waste that uses water as a coolant. These contaminants cause heat increases the temperature of the water unsuitable for aquatic life (organisms, fish and plants in the water). Plants, fish and dead organisms will break down into organic compounds. For the decomposition of organic compounds requires oxygen, resulting in decreased oxygen levels in water.

Broadly speaking, these water contaminants above can be grouped into:

1. Organic contaminants, which can be experienced both decomposition by microorganisms and which can not experience breakdown.
2. Inorganic contaminants, can be heavy metals, mineral (inorganic salts such as sulfate, phosphate, halogenida, nitrate)
3. Pollutants in the form of sediment / soil or mud sediments.
4. Pollutants in the form of a radioactive substance e) material in the form of heat pollution

Parameters and water quality standards

You have to know that the source of said contaminated water contains contaminants, if that can interfere with the welfare of living things (animals, humans, plants) and the environment. However, water containing certain contaminants polluted say for certain, such as for household use may not necessarily be said for other polluted. Thus the water quality standard for each purpose will vary, depending on water usage, for different household needs with water quality standards for other purposes such as for agriculture, irrigation, power generation and industrial use. Thus the parameters used must be different too.

In accordance with the contaminants found in water sources, the parameters used to determine water quality standards were based on the contaminants that may exist, among others, can be seen from:

1. color, odor, and / or taste of water.
2. The properties of inorganic compounds (pH, specific conductivity, oxygen solubility, the soluble salts and the presence of heavy metals).
3. The presence of organic compounds found in water sources (ie CHCl3, phenols, pesticides, hydrocarbons).
4. Eg radioactivity ß rays.
5. Bacteriological properties (eg bacteria Escherichia coli, cholera, dysentery, typhoid and many more).
