Surface water pollution has pollution of lakes, rivers and oceans as examples and is basically of water bodies that are open. Marine pollution is a sub-category of surface water pollution.
IN ADDITION TO READING ONLINE, THIS TITLE IS AVAILABLE IN THESE FORMATS:
It is the introduction of contaminants or their entry into large water bodies. Rivers are means by which seas are polluted due to rivers emptying into seas. A typical example is the discharge of industrial waste and sewage into the ocean and this is very common in nations that are just developing. Groundwater pollution is also known as groundwater contamination and there are slight relationships between surface water and groundwater.
Groundwater is quite exposed to contamination from some sources that are not contaminants for surface water. It is important to note that the difference between point and non-point sources is quite irrelevant. Surface water and groundwater, even though they are separate resources are interrelated. It is surface water that percolates into the soil and it becomes groundwater. Also, groundwater can become surface water by feeding water bodies.dienerirona.gq
Water pollution conclusion essay
Sources of water pollution are classified into two categories based on the origin. Point source water pollution is contaminants that enter a water body through an identifiable and single source like a ditch or a pipe. A point source includes industrial storm water, storm sewer systems of municipals, and discharge from a sewage treatment facility, a factory or even a storm drain in the city. Non-point source pollution is contamination that is not originated from just one single source.
This form of pollution occurs from the agglomeration of little quantity of contaminants collected from a huge area. A typical example is the process of leaching of compounds of nitrogen from agricultural fields that are fertilised. The particular type of contaminants that lead to pollution of water includes quite a wide range of pathogens, chemical and physical changes including discoloration and temperature elevation.
Even though a number of the substances and chemicals that go under regulation occur naturally calcium, manganese, iron, sodium, etc. It should be noted that negative impacts can arise from a high concentration of substances that occur naturally. Substances that deplete oxygen can be materials that occur naturally like plant matter e. Other anthropogenic and natural substances may lead to turbidity which disrupts growth of plants by blocking light and blocks the gills of a few fish species.
The alteration of the physical chemistry of water includes electrical conductivity, acidity pH change , eutrophication and temperature. Eutrophication is basically the concentration increase of chemical nutrients of an ecosystem to a level that causes an increase in the primary productivity in the ecosystem. Pathogens are microorganisms that cause diseases. Waterborne diseases can be produced by pathogens in either animal or human hosts.
A popular indicator of water pollution is Coliform bacteria; it does not cause any disease but is a good bacterial indicator. Poor onsite systems of sanitation pit latrines, septic tanks or insufficiently treated sewage can result in high pathogens levels.
Older cities have ageing infrastructures that may include sewage collection systems valves, pumps, pipes that are leaky and can lead to overflow of sanitary sewers. There are also combined sewers that sometimes discharge sewage that is untreated during storms.
Poor management of livestock operations is also a major cause of pathogen discharges. Inorganic and organic matter can also be contaminants. A lot of chemical substances are very toxic. Examples of water pollutants that are organic include: waste from food processing, detergents, herbicides and insecticides, by-products of disinfection, petroleum hydrocarbons, drug pollution, etc.
If a household or business is not covered by a municipal waste treatment facility, there may be need for separate septic tanks that gives first treatment to the wastewater and infiltrates the wastewater into the ground. If this is not carefully and properly done, it can cause groundwater pollution.

Most industrial facilities churn out a lot of wastewater that is quite like domestic wastewater and can also be treated by wastewater treatment plants. Some industries generate wastewater with very high concentration of nutrients like ammonia, toxic pollutants e. Water pollution harms this important resource by making it unfit for human use and invariably causes harm to human health and the environment if proper measures are not taken to battle water pollution. The presence of such substances in the environment which can be harmful to the various forms of life on the earth is what we term as pollution.
Under this category, the contamination of water bodies is specifically referred to as water pollution. Lakes, oceans, rivers and groundwater mainly constitute the water bodies on the earth. However, due to various activities, especially of the human beings, this water has been contaminated to such an extent that researches have been forced to study the effect of this phenomenon on the life on earth.
The contamination of water bodies can be classified into three types, mainly, groundwater pollution, marine pollution and surface water pollution. Contaminated water from drains and industries which flows above the topmost layer of the soil usually creeps into the soil and gets mixed with the groundwater, thereby polluting it. This contaminated water then interacts with the nutrients present in the soil and alters their quality.
This is termed as groundwater pollution. Similarly, the wastewater released from the industries flows into the river and thereby reaches the seas and oceans. This is termed as marine pollution. It only affects humans but has an adverse effect on marine life as well. In the case of surface water pollution, the wastewater remains on the surface of the earth and polluted it. This leads to the deficiency of nutrients in the soil as nutrients from other sources are not able to penetrate in the soil due to the presence of this contaminated water. Industrial Waste — Pollutants such as mercury, asbestos, lead and petrochemicals which are released as industrial waste, find their way in the water bodies and contaminate them.
Often this makes the water unfit not only for drinking but also for domestic use and survival of marine life as well. There have been numerous occasions where groups of dead fish have swept ashore at a given time due to the sudden increase of such chemicals in the water. Moreover, the spillage of oil from the ships often creates a hindrance for the oxygen in the air to get dissolved in water, thereby making it difficult for the marine animals to breathe.
Sewage and Waste Water — Another instance where the water bodies get contaminated is due to the release of sewage and wastewater directly into the bodies without being treated. Untreated wastewater can at times pose to be very poisonous not only for human life but for fishes as well. Global Warming — Global warming is another phenomenon which has been often credited with the cause of increasing water pollution. There has been a rise in water temperature levels due to global warming which has even led to the death of water animals as well as plants as they were not able to survive in the increased temperatures.
Radioactive Waste — Radioactive waste is another major cause of water pollution. Radioactive substances are utilized in atomic power plants, mechanical, medicinal and other logical procedures. They can be found in watches, glowing timekeepers, TVs and x-beam apparatus.

There are likewise normally occurring radioisotopes from creatures and inside the earth. If not appropriately discarded, radioactive waste can result in genuine water contamination episodes. Dumping — Dumping of strong squanders and litters in water bodies cause water pollution.
