Pollution is the addition of any harmful addition to the environment. River pollution is caused by a number of factors including sewage pipes, corporation waste and illegal dumping. Many Rivers around Ireland are or have been polluted in the past, such as the River Lee, Liffey and Tolka. River pollution isn’t as big of a problem as it is in some parts of the world such as India, however it can kill fish and other organisms living in the river and can also be a threat to human health. According to the Environmental Protection Agency, 71 % of the country’s rivers are in good condition, however much can be done to improve this.
The sewage water would mix with the pipelines and thus, it would pollute the water of the agriculture and the drinking water. Moreover, the pollution of water would lead to the poor health of the people. The people would suffer from toxicity and the water pollution would lead to the increase of the mortality rate in children. The water pollution is a very threatening problem and thus ,the society ahs to start to act accordingly to address this problem. (AUC, 2011) The Nile river is one of the most important and crucial sources of life in Egypt.
That whole elaboration on my part was a segway into some of the downsides associated with Hydropower. One major drawback is the disruptive nature hydropower has in regards to natural habitats. Specifically, aquatic ecosystems that reside in rivers and streams can be severely altered by the presence of hydropower plants. Fish or other aquatic animals may accidentally get caught in the turbines, resulting in death. This also has the potential to block migration and mating patterns, which would lead to a decrease in the population of certain species (“Various Disadvantages of Hydropower,” conserve-energy-future.com).
The roots of the riparian vegetation are also significant for it sips most of the nutrient pollutants dissolved in groundwater before reaching the river. If the riparian vegetation was disturbed, the nutrients coming from soil goes to the river, the water temperature increases, and there will be not enough trees that evaporate the running water that directly goes to the river resulting to soil erosion and excess of nutrients such as phosphate and nitrate that result in eutrophication. (Mihov, S. WWF) Eutrophication leads to degradation of oxygen and it causes death of fishes and other aquatic organisms. Disturbance of flora and fauna caused by deficiency of oxygen then follow poor water quality and greatly affects diversity. According to Covich, A.P et al, the presence or absence of a
Direct deposition of animal wastes within rivers or indirectly through runoff can pose a threat to human health, because of the presence of harmful pathogens such as Escherichia coli (E.coli) (Nagels et al., 2002). One of the methods to access the health of any river is to monitor the Water Quality Index (WQI). Data on the water quality are used to determine the status by examining to see whether it is clean, slightly polluted or polluted. Water quality index have been conducted by several researchers (Gupta et al., 2003, Kannel et al., 2007, Said et al., 2004, Taner et al., 2011). Hence, the impact of livestock farming on water quality is established for the improvement of future water quality.
(Moloi, 2013). Damming of rivers on the other hand has a high impact on the quality of the water. If a plant will be isolated into the water for a long time, this may cause the inclination of phosphates and other dissolved nutrients in the water or simply, eutrophication. (Moloi, 2013). It has been said that water pollution starts to transpire when unwanted flow of liquid wastes spreads over the water source, which later on causes the change of the water quality.
Earth is basically surrounded with potential clean energy source. However, without proper management the pollution can ruin these luxuries. Polluted water is certainly harmful towards aquatic beings, but not only that it also can cause degrading of riverbanks due to dead plants that could not sustain the structure of the soil which usually the root cause of flash
Turbidity is finding if the water is clear or not. Turbidity is caused by suspended solid matter in the water and high can be caused by numerous things such as: soil erosion, algal growth and urban runoff. High levels are tubidity is bad because the water losses the ability to support life in the water as the solid matter can block out sunlight . Nitrates and nitrites are chemicals mainly from fertilizers which come from sewage discharge or run-offs from farms nearby. Excessive algea growth can be caused by the presence if nitrates in water which can cause a loss of aquatic life as the algea will block off sunlight into the water  .
Water pollution is defined as when many toxic chemicals are added into the water the water is polluted. A small drop of harmful chemical in a house pump or cannel can polluted the water in heavy amount. This can be much harmful for human. While a large amount, a chemical in a river can pollute low water. “Any change or modification in the physical, chemical and biological properties of water that will have a detrimental consequence on living things is water pollution.” Water pollution affects the drinking water, lakes, rivers and all over the world.
