The salt that ends up in the ponds, streams, and rivers adds a layer of salt water, which restrains nutrients away from underwater vegetation and organisms (Beaudry, Frederic). The chemicals cause many different reactions to the vegetation, which results in the plants dying. The harmful effects of sodium chloride and other chemicals can damage vegetations development and can cause plants to die. After road salt is applied to major highways, there is a considerable amount of salt left over and the residue can cause serious problems on the environment. When road salt is being used it should be more controlled and the amount should be managed so that there are no left-over chemicals on the road that could cause damage.
Nutrient pollution coming from agricultural runoff and other fertilizers allows for the growth of species that upset the balance of the ecosystem such as Cattail, harmful algae bloom, and duckweed. The sulfur in the agricultural fertilizers leads to accumulation of toxic mercury in fish, birds, and mammals. Also, exotic animals or invasive species displaced native and threatens to disrupt the ecosystem balance. The purpose of this experiment is to determine how the water quality affects the Everglades ecosystem and how water pollution impacts different species. Urbanization is a big threat that contributes to poor water quality in water pollution.
Fertilizers remove the nutrients of the soil damaging the soil and the local environment and after being mixed with the soil, gradually reduce the fertility of the soil. In the study of (Southland) using fertilizers consists of substances and chemicals like methane, carbon dioxide, ammonia, and nitrogen, the emission of which has contributed to a great extent in the quantity of greenhouse gases present in the environment. These facts are alarming and a serious step needs to be taken as soon as possible to avoid more severe consequences. This in turn is leading to global warming and weather changes. The use of fertilizers for growth and cultivation is keeping our stomach filled for now, but then if things keep on progressing the way they are, it won’t take long to see the times where there is lack of food, water, and health.
Industrial corporations have continuously used bodies of water to their advantage by having their factories use water as an energy source and trash bin. Toxic chemicals are released by these factories and sometimes directly dumped back into the water. Aquatic plants benefit from the carbon dioxide released by factories, but too much can harm the biodiversity of that ecosystem and other marine life and acidity levels will also rise. A bigger population means more consumption and as the human consumption has increased throughout the years, landfills have been overflowed by large amounts of trash. When liquids and other materials begin to degrade, they release a juice that can be toxic if consumed.
LITERATURE REVIEW What is water pollution? As the country is becoming more and more populated, the demands for social services have increased significantly. This has led to an increase of the pollution in many developing towns such as Ga-kgapane. The most disturbing and problematic forms of pollution in Ga-kgapane is the pollution of the natural streams. Water pollution is when there is a build of one or more substances in water to such an extent that it causes problems for animals or plants.
Phosphate can come from some agricultural fertilizers, manure, and organic wastes in sewer. If there is too much phosphorus in water then it can increase the abundance of plant life, which can be good for the aquatic plants, but could lead to suffocating the creatures in the water since the oxygen will be used up. The further away the water source is from civilization, the less unnatural ions will be present in
Nitrogen is a major component of the atmosphere, but an essential nutrient in short supply to living organisms and is often the most limiting nutrient for plant growth but can also be found in organic matter in soil and the oceans. It is used to make organic molecules such as amino acids (and thus proteins and nucleic acids) for living organisms. Animals require nitrogen for metabolism, growth, and reproduction and get it by consuming nitrogen-containing molecules in organic matter of both living and dead sources. (Pidwirny 2008) The nitrogen cycle can be summarized as follows; Nitrogen in the air (70%) gets converted into a useful form by nitrogen-fixing (conversion of nitrogen into nitrates) bacteria in the soil. This is assimilated by plants and animals.
2.8.2 Urbanization Urbanization led many areas becomes more modernized. Lowland areas have been reclaimed by taking land from the hills. There are also small rivers that filled up to be used as a building site. Activities such as these are a common factor of flooding. In the past, creeks and valleys turned into water flow, now the area has been covered with soil.
Canalization works include the widening and deepening of channels as well as lining the banks and beds of the channels. They also include the replacement of undersized structures such as bridges. These works are necessary, as the original channels have become undersized as a result of the increase in flood flows caused by development. Flash flood also can be overcome with storage ponds of flood attenuation. Ponds such as disused mining pools can be used for flood storage.
Sedimentation and pollution in the streams or rivers causes effecting the life duration and quality of fish and other species. Land degradation are also reducing the water holding capacity of soil on the contrary, increased by flooding and leaching of water and nutrient losses mainly as nitrate form. The other substantial change in land usage is the maintaining of sustainability. According to FAO statistics, 28% of the total earth surface have any limits on its use for agriculture while 28% is too dry, 23% has chemical imbalances, 10% is too wet, 6% is permanently frozen, and remaining 22% the soil is to shallow for use as arable land. Altgouhg there are some discussions about the renewable subject of soil today, generally if the soil formation rate exceed the degredation rate, soil is accepted as renewable, on the contrary the degredation surpasses the formation, soil is accepted as
Eutrophication, which is excessive richness of nutrients in any form of body of water, frequently due to runoff from the land, which causes a dense growth of plant life and death of animal life from lack of oxygen, is another reason why the creek could be polluted. Fertilizers are used in farming to provide crops with nutrients, but they also play a big role in the Eutrophication process. If too much fertilizer is used, it leaches from the soil in
Pollutants from factories, cars, boats, and litter are all the things humans use to pollute the bay. The bay contains a high amount of phosphorus and nitrogen. Phosphorus and nitrogen are needed for organisms and plants to be able to survive. However, an excess amount of phosphorus and nitrogen degrade the quality of Chesapeake bays water. Phosphorus and nitrogen feed algae blooms that block sunlight to the underwater bay grass and leaving a low supply of oxygen in the water.
Nonetheless, in the long run, this strategy will leave a huge footprint in the environment. The land is going to become fragile to a point that it can become sterile, which leads to a significant problem. Sterile land becomes useless since it will not be able to generate profit. As an example, vegetation from agricultural purposes, would not be able to survive in the land due to the scarcity of nutrients. A solution that most farmers use as a short-term solution is to use a new hectare recreating the same procedure burning trees field, but this procedure involves deforestation of new hectares, which will cause worst problems in the long run, like deforestation.
Due to the river being connected to many other rivers and lakes, the contaminated water travels downstream and contaminates the water in the other water sources. This is ongoing and makes it harder for the treatment of the water. Propose one possible rehabilitation technique. A rehabilitation technique that could be put in place at this water source would be to enforce harsher penalties for polluting the water and educating the public on the consequences of the pollution. This would discourage people from polluting and would inform them on what happens if they do pollute the water.
