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. http://c2.thejournal.ie/media/2014/07/tolka-river-pollution-5-390x285.jpg …show more content…
Possible environmental impact
If river pollution continues it may lead to the increase of pathogens in the river channel and further biodiversity loss. Sewage systems often flow into rivers in Ireland, this sewage may contain many pathogens. If sewage treatment and management is not controlled, these pathogens may end up in people’s drinking water, bathing water etc. Poor sanitation is a major problem in developing countries such as India where cholera and dysentery are killing millions. If these pathogenic rivers flood, it may destroy farmland and cause it to become baron
6. Solution/Proposed solution
River pollution can be both prevented and controlled. Prevention should be the main goal, but if the pollution that is already occurring can be controlled, it will make a positive difference. The most obvious way to prevent river pollution in Ireland is to stop dumping industrial waste, sewage and household waste into the river. This will prevent the entry of pathogens and will prevent further wildlife being killed. Large rubbish items that are dumped by humans interferes with the flow of water by causing an obstruction. The river velocity may increase in order to bypass the dumped rubbish which increases the erosive powers of the river. If this waste is cleared, it may prevent the erosion of the surrounding
Water pollution before the Gilden Age greatly impacted public health, but it was often ignored until progressives pushed for change. Sewage was the biggest factor in water pollution, and it “was primarily a public health problem, but it also damaged private property, recreation and fisheries”. The lack of waste disposal caused many people to be infected with diseases which led to progressive policies being formed to fix the issue of water pollution. In 1899, The Rivers and Harbor Act was passed which prohibited the discharge of waste into navigable waters, and the sanitation of water greatly improved after epidemiologists found the negative effects of waste disposal. The improvement of the sanitation of water impacted public health by decreasing deadly outbreaks of diseases like cholera.
The Indian River Lagoon is a beauty to Florida, and a natural landscape, but, it is at risk from pollution. Chemicals, algae blooms, and harmful things that humans do to pollute it, it also puts the animals living in the lagoon at risk of dying, and becoming endangered. The causes of the Indian River Lagoon take effect greatly. Freshwater is also very important, it is a vital life source. There are harmful chemicals from pesticides, fertilizers, impacts this problem a lot.
Herbert Run is prone to pollution as a possible result of the residential area and open to sewer lines. This results in litter being in the water, which has an adverse affect on the water. Commons stream is also cluttered with litter and students moving around the immediate areas that surround the stream. The conductivity graph shows a higher level of conductivity in the Commons Stream than Herbert Run. The conductivity level is twice as high in Commons Stream in comparison with Herbert Run, which means that the concentration of dissolved solids that are ionized in this stream is higher.
“Carried by snow melt, rain water, and groundwater, NPS pollution contributes sediments, nutrients (nitrogen and phosphorus), toxic substances, and pathogens to water bodies” (Maine Rivers 2005, ijc 2008). The Non Point Pollution generally due to stormwater in the downstream portion of the river; which are the most populated areas situated near the estuary;With the stormwater large amounts of pollutants are washed off to the river because of the impenetrable surfaces of that area which does not allow water to seep into the ground. Other sources of Nonpoint pollution are seepage from broken sewage and septic tanks, runoff from construction sites ,nutrients,sediments and chemicals from agricultural farms and roads. According to the report of International Joint Commission in 2008; “This untreated runoff may contain litter, dust, soil, oil and grease from roads, garden waste, chemicals, and nutrients and pathogens from animal feces and fertilizers” (IJC
Although beneficial, the removal of sediment within bodies of water is of a costly nature and is usually a last resort. (Lenntech,
Rivers change the shape of the earth by eroding away sediments of the earth's surface. There are four different types of erosion created by rivers: hydraulic action, abrasion, attrition and solution. Hydraulic action is when the river bank is weakened by the velocity of the river, which allows air to enter small breaks in the river bank, and the bank slowly erodes away. Abrasion is when the bed and bank of the river is worn away by rocks carried by the river. Attrition is when rocks in the river forcefully hit each other and create smaller sediments.
When concerning our drinking water it should be considered that pathogenic organisms may contaminate soil, as well as stick on to the sediments in the surrounding area; making it more tricky to clear completely. Nitrate poisoning is another large concern,
Water Pollution in San Joaquin Valley San Joaquin Valley is a place that stretches from 7 different counties such as Stanislaus to Kern county. San Joaquin Valley is known for their agriculture land since the late 19th century, which feeds most of the United States with the vegetables and fruits that are grown in the valley. The rich life of life in agricultural fields rely on the water supply that the valley contains such as groundwater and water on shore. Throughout the past decades, the water quality in San Joaquin Valley becomes to decrease from clean water to polluted water.
In addition, the pollution spread into the water as well, all the waste within the factory had to be removed. Instead of properly disposing of the waste, it was dumped in the rivers. By doing this it contaminated the river, causing people to become ill. “As countries industrialized, they also urbanized. This was a result of people moving to cities in large numbers in order to gain factory jobs” (Document 6).
Towards the middle of the documentary they give you very good facts such as why it's bad to litter in the river as well as why the chicken pollution is bad for you. Many families where affected by the pollution. " A number of families have sued poultry companies to hold them liable for the illnesses suffered by their children"(45:32). Littering in the river is bad for the environment and people, so is the chicken pollution that is spread around the land close to the school and homes. The chicken pollution that is spread around the land possesses disease concerns.
The canals next to the Nile will fill with the Nile floodwater. At the same time, the floodplains are then are then covered in a new batch of dirt that will later help crops
The water pollution is polluting great deal of their rivers. The reason for a mass of this is “Industrial runoff, poor sewage treatment , and catch basins”(Auslin). All of this is making the water of china is deadly for people to drink and to swim in. A group did a study in 2011 that said “39 percent of china’s seven river basins were too polluted for general use, including 14 percent that were unfit even for industrial use. In 26 key lakes and reservoirs, only 42 percent of total water was deemed fit for swimming and fishing, while 8 percent was unfit even for industrial use”(Auslin).
Intro: Water pollution has caused so many problems to our waterways that no one really knows how to help. Water pollution caused; dead zones, oil spills, garbage floating around, and unsafe drinking water. People disagree about water pollution because, people have found ways to improve and help out the problem that water pollution has caused around the world. Others believe that that water pollution has created situations and are in the process of figuring out solutions. Marine life habitats are getting destroyed, marine life is declining everyday, how and where the garbage is getting into the oceans, and the drinking water is becoming seriously unsafe to drink.
Rivers that passed through urban areas became a holder for human waste products. Factories began releasing pollutants directly into rivers and streams. By the 1850’s inhabitants began experiencing epidemics of cholera and typhoid. In 1969, chemical waste releasaed into Ohio’s Cuyahoga River caused it to burn into flames and the waterway became a symbol of how insutrial pollution was destroying America’s natural resources. Aditionally, mining activties also affected water pollution by increasing the amount of toxic elements released into the environment.
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. The objective is to divert the flood water through such ponds and thus regulate the outflow so that the flood peaks are attenuated.
