Recommended: Oil industry pollution

What sources are the biggest problem in surface water pollution? types of pollution:

There are a number of major types of water pollution. The polluters are:
- petroleum products
- Pesticides and herbicides
- Heavy metals
- hazardous wastes
- fertilizer
- sediments
- infectious organisms.

Petroleum products which among other things are used for fuel, lubricant and plastics, can get into the water through the discharge of ships and tankers, and the leaking from pipelines and underground storage tanks. Oil may also contain hazardous polychlorinated biphenyls (PCBs), highly toxic and highly persistent chemical compounds. Oil in the feathers of birds or other animals is often fatal to them. An oil spill near the coast is often a catastrophic

by combining targeted BMP implementation strategies only in small parts of the catchment.

By using Best Management Practices there was looked at the cost effectiveness in reducing sediment ,nitrates and phosphorus pollution which will get into the surface water via fertilizer. This fertilizer is used by farmers and the use of filter strips at the edge of a corn field should prevent the loss of all these nutrients in the surface water. This method proved effective since it reduced the overall pollution and it shows that by combining targeted BMP implementation strategies, multiple pollution types can be reduced at small cost.

By purifying the sewer water before it enters back into the surface water.

After the dirt and sand are removed from the water by purification, the waste water is put into aeration tanks. In here, the bacteria and oxygen is added. These bacteria need oxygen to live so that is the reason it is added. The bacteria do the real work. They eliminate the tiny dirt particles from water that are still left. The only thing that is left after this is sludge. This gets fermented for power to do the purification all over again. This way it is a very sustainable process. The clean water is returned to the nature.

    There are many causes to petroleum in b the oceanic environment. Oil naturally seeps into the ocean but the natural concentrations have been greatly exceeded. Shipping oil from one place to another contributes the most to oil in the ocean. The crude oil from transportation b is discarded into the ocean while cleaning bilges, which are the lowest compartment in ships, and transferring oil from tank to tank at sea. “Disasters like shipwrecks, oil tanker accidents, and offshore oil rigs fires continue to this problem, as does the disposal of urban garbage into oceans, dumping of waste oil by passing ships, commercial coastal and off-shore entertainment, and deep-sea industrial and nuclear waste dumps”(“Marine Water Quality”). Another large polluter is the oil industry. Tanker ports and refineries are located by the coast for shipping purposes. The coastal areas receive considerable damage from the spills. “Large numbers of seabirds are killed annually, their oil-matted plumage making flight impossible and exposing them to hypothermia. Oil-soaked fur of marine mammals loses its water repellency, also leading to death by hypothermia. Ingestion of oil by fishes, birds, and mammals may also result in death”(“Marine Pollution”). Another source of petroleum pollution is from the city streets. Oil runoff from urban streets and sewers enter waterways and the ocean. Oil has a very long term ecological impact on the ocean and the marine ecosystems. “The presence of oil in marine waters severely degrades water quality by clogging an animal’s feeding - structure, killing larvae, and blocking available sunlight for photosynthesis”(“Marine Water Quality”). Petroleum pollution has been a large problem for a very long period of time. “As early as 197p, oceanographic ecologists noted that they could rarely pull a net through the surface of the ocean without collecting some form of tar or

    The Gulf of Mexico oil spill has had an extremely negative effect on the surrounding wildlife and ecosystem. The oil spread across the gulf contaminating any living organism that came into direct or indirect contact with it. The oil cuts off the ability of oxygen from the air to move into the water which directly harms fish and other marine wildlife that require that oxygen. The dispersant that the BP is using to try and break up the oil moves the slick into the entire water column which contaminates the ocean floor which would most likely not have seen any damage if it wasn’t for the use of these dispersants. More than 400 species that live in the Gulf Islands and marshlands are at risk and as of November 2 s...

    Phase one in process of waste water treatment begins in the home, local businesses and community. Waste water from these buildings and surrounding areas travel through a pipe, or sewer which is sloped downward, and with the assistance of gravity, travels toward the waste water treatment plant. However, in larger communities or communities with unevenly leveled terrain, waste water cannot keep getting deeper to rely on gravity to transport the waste water and must pumped up by the assistance of a lift station so it may continue to travel to the water treatment plant. Once the waste water arrives at the waste water treatment plant, the first step is the removal of large debris such as diapers, underwear or other non-biological...

  • Water Purification Conclusion

    Water plays such an important role in our daily lives. 70% of our body is composed of water. 70% of the earth surface is also made up of water, but out of the 70%, only 1/3 of water is consumable. In fact, this amount has been continuously to decrease as more and more industries began to pollute and damage the water. For example, many toxic chemicals may be released into the water thus making the water impure. Such pollutions and damages lead the water to be contaminated and inconsumable as it may cause severe diseases. Water purification can remove all the unnecessary bacteria and viruses from the water that is hazardous for our health. Water purification may also improve the flavor and appearance of water. It removes the unpleasant odor. Therefore, water purification became one of the most useful and popular process used by people all over the world today. It is by far the most recommended and safest water treatment that is commonly used to purify damaged water into consumable water. Water purification provides us with safe, pure and clean water to consume and use.
