1) What is eutrophication? Eutrophication is the mechanism which any body of water such as a river, stream, estuaries, lake or the sea gets contaminated by excess nutrients such as nitrates and phosphates which causes an accelerated rate of plant growth, sometimes called an algal bloom. The accelerated growth and proliferation of plant life, algae and phytoplankton decreases the availability of light and dissolved oxygen in the water column. As a direct result of the increased plant life and the accumulation of dead decaying plant matter dissolved oxygen levels are further decreased since the bacteria that readily decomposes the organic matter also require oxygen to live (Thinkquest, 2005). When oxygen levels fall below a threshold level, fish and other aquatic animals cannot survive which is a condition is called hypoxia. Eutrophication can have many adverse effects on the biodiversity and ability to survive of many native organisms (Oregonstate, 2011). Opportunistic organisms, such as algae and cyanobacteria, cause undue stress on the fragile aquatic environment and disrupt the natural ecological balance of any aquatic environment. Therefore as a direct result many species get stressed to the point of completely dying, while sometimes being replaced by invading or opportunistic species.
2) What is the difference between cultural and natural eutrophication?
Most eutrophication in our bodies of water is directly caused by human infringement upon the environment and the nutrient, pesticide and chemical runoff coming directly from industrial activities, sewage treatment plants and with the main culprit being industrial farming and cattle production. On the other side natural eutrophication occurs when sediments add decaying matter is naturally deposited by the natural erosion caused by rain and water flow. Seasonal flooding, such as in flood planes and valleys also carry a large influx of sediments, decaying matter and excrement from animal life which can provide a large natural source of eutrophication of any body of water. The contamination created by the choking plant matter. Low oxygen levels and increased sedimentation can also affect water quality levels and cause the water to become toxic and unfit for human consumption.
3) How do you combat eutrophication?
Efforts to control water pollution and eutrophication have been a hotly debated issue since the 20th century. In order to control the impact of human activity to our water resources careful planning, assessment and control of fertilizer use, controlling runoff from farms and cattle ranches. These procedures limit the use of pesticides and fertilizers to prevent toxic buildups on the soil that will eventually reach any bodies of water in the area. Prevention is the best strategy in order to prevent further damage to the environment and pinpointing all large sources of nutrient runoff and contamination around our water sources and addressing them in an environmentally responsible matter will serve to minimize and reverse the impact in many of our aquatic environments. Water is one of the most precious and valuable natural resources due to the fact that it is needed for the survival of human beings. Governmental agencies around the world have to do a better job of safeguarding and protecting our water resources. “Water pollution prevention and control measures are critical to improving water quality and reducing the need for costly wastewater and drinking water treatment” (Epa, 2011).

...level goals. In addition, MCLs are founded on affordability, treatment technology and other feasibility factors. The process of determining an MCL commences with an assessment of the harmful results of a chemical and the quantities in which this chemical has to be present for causing harm (Kamrin, 1997). This exercise culminates in establishing a Reference Dose, which defines the dosage that provides protection against the adverse effects of a chemical. Subsequent to testing these dosages on animals, the results are extrapolated to humans. The entire process is on the basis of the standards and procedures established by the EPA (Kamrin, 1997). The chief cause of water pollution is human...

Water Pollution

...into the river each day. This caused the river to become the most polluted water body in Britain. The main effects of all these wastes were that the water temperature of the river grew to a great extent, causing a decrease in the dissolved oxygen it contained. And thus, it was no surprise that no plants or animals were able to survive properly in the water of Tees. Due to the decreased levels of wildlife survival, the problem was sought to be tackled by the concerned government departments and the main solution that they brought to the scene was declining permits and tightening the discharge permits to industries and companies situated in and around the...

...water pollution -- or more specifically, using tampons as a method for identifying where wastewater is leaking into streams and rivers. The leaking of wastewater into streams and rivers is actually one of the main causes of water pollution. Most tampons are made of natural, untreated cotton, a material that readily absorbs a class of chemicals called optical brighteners. Optical brightening agents (OBAs) have a "whitening effect" and also enhance color brightness; optical brightening agents are also used in toilet papers, detergents and shampoos. These qualities of optical brightening agents, therefore, make them ideal indicator of the presence of...
