Fish, plants, water and other organisms are living in our ecosystems. This type of pollution is not only harming them now, but will continue to harm them in the future. There are many ways how water pollution is harming our ecosystem, whether it is oil spills, marine dumping, nuclear waste, or atmospheric pollution, it is all harming water. Underground storage leakages play a role, yes, they are useful in many ways, but they are also very harmful. “Over time the steel corrodes and causes leakages, affecting soil and groundwater” (“Underground Storage Leakages” 1).
A major component of the chemicals and organisms that emerge from contaminated waters is nitrogen. Several organisms play different roles in the nitrogen cycle. The nitrogen cycle occurs in bodies of water especially in those that have the necessary and beneficial bacteria that break down any waste into nitrates that can be consumed by many organisms. There are other harmful bacteria, however, that are denitrifying bacteria that reduce nitrate into gaseous nitrogen that is not helpful to any organisms. The denitrifying bacteria turn helpful nitrates into harmful ammonia and nitrites.
Hypoxia is largely caused by nitrogen fertilizer application for agriculture, with heavy concentrations coming from the Midwestern US. Nitrogen mobilizes as nitrate, and is transported via surface water runoff. The runoff enters tile-drain supported ditches, enters streams and joins the Mississippi river, eventually reaching the gulf. Nitrate mobilization is a problem for human health, and ag. runoff is also often attributed to the contamination of surface and well-water sources in rural areas.

Key factors in economic development are manufacturing, farming, and harnessing energy. Although these factors have consequences to their exploitation such as water used to produce steel is water that 663 million people who don’t have access to could use to drink. Realizing toxic waste, a by-product of manufacturing something into the Oceans can disrupting the balance of the ecosystem. Side effects like fertilizer flowing into rivers and lakes throwing the ecosystem of balance and causing eutrophication to occur, making the water dangerous to drink. Another factor in the depletion and deterioration of our water resources is from harnessing energy, hydroelectricity uses a dam to harness the water flow to produce energy which disrupts the balance of the river and lakes.
Also, the result of this is rich plant life which prohibits recreational activities. Plankton blooms depress oxygen levels (as mentioned before) and therefore, endanger living organisms. Major sources of nutrients are municipal sewage and agricultural runoff. Toxic Materials: Can affect the health of aquatic organisms and their consumers, and the people who drink the contaminated water. The toxicants include lead, mercury, DDT, PCB, benzopyrene, oil, and dibutyl phthalate.
Too much nitrate can cause a negative effect on the plant including nitrate toxicity. High levels of nitrate are not only bad for plants but can also be dangerous to animals or humans in their presence. Here I discuss the scientific evidence of the effects of nitrate accumulation on plants and the environment and argue that too much nitrate accumulation can be harmful to its surroundings. Nitrogen is essential for plants because it is an essential component of all proteins. A lack of nitrogen in a plant diet can result in slower growth, stunted growth, and even chlorosis (1).
Fertilizer pollution interacts with economic and political issues, and many things must be done in order to help resolve the issue. When Fertilizers are used, the rainwater washes them, and they merge with the rain water, as they evaporate. The Fertilizer runoff then goes into the water, and causes large problems. The main problem with this is that the fertilizers will end up in places like lakes and rivers, which can be a huge problem if there is a marine ecosystem. When the fertilizers go into the water, they cause something called algae blooms, in which all the algae, will bloom and grow very fast to the top of the water.
Chemical Water Pollution Many industries and farmers work with chemicals that are dumped into water. These include chemicals that are used to control weeds, insects and pests. Metals and solvents from industries can pollute the sources of water. These chemicals are poisonous to the living organisms in water and may slow their growth, make them sterile and can kill them. 8.
