The Lake Receives More Water From Sewage Than Natural Water Flow

SELECTION OF TOPIC:

Due to over increasing population, pollution is also increasing due to this the river and lake water are getting contaminated the water from factories and are directly let out into the water and the sewage from the cites are thrown into the water which made water contaminated. The people in urban areas and also villages wash their clothes & animals in the river, lake & when oil tanks are been transported from waterways the oil leakages from the ship spread in the water which harms the aquatic life. The animals who live in water at this type of contaminated thing and their life & becomes in danger. The people who consume these types of fishes they harm their life in this way sewage let out in Lake River.

Sewage is a water-carried waste, in solution or suspension that is intended to be removed from a community. Also known as wastewater, it is more than 99% water and is characterized by the volume or rate of flow, physical condition, chemical constituents, and the bacteriological organisms that it contains.

AIMS AND OBJECTIVES :

To learn why the lake receives more water from sewage rather than natural sources

Objectives:

  • To make people aware of the over usage of water.
  • To make awareness about increasing water pollution.
  • To restrict the factories on letting the sewage in water bodies.
  • To spread awareness about the decline in natural resource- water.
  • Increasing pollution resulting in poor health of human being as well as animals.
  • Letting out sewage in water harms environmental factors.
  • Pollution causes the spread of diseases.
  • Increase the number of water bodies for storage of water.
  • Sewage can be disposed of in other ways like dilution.
  • To make people aware that we contaminate water too by our daily activities.

METHOD AND METHODOLOGY :

The Project has been done in a knowledge acquiring method. It improved our knowledge of our environment. The information is acquired by means of own knowledge, Internet sites and books related to the environment.

In the past three decades, multi-billion dollar investments to upgrade municipal sewage treatment systems in the Great Lakes basin have abated some of the worst pollution problems, such as the extreme eutrophication of Lake Erie and Lake Ontario. However, despite these advances, the fact remains that much of the surface waters surrounding large urban areas are often unsafe for bathing, lack biological diversity, and the local fish are unsafe to eat.8 This is largely due to contamination caused by the sewage dumped directly into local waters.

Unfortunately, the antiquated sewer systems found in most Great Lakes cities continue to regularly release huge quantities of partially treated or untreated sewage directly into the environment through spills, bypasses and combined sewer outfalls.

Typical municipal sewage is a foul cocktail of water, human waste, micro-organisms, disease-causing pathogens and hundreds of toxic chemicals. The principal pollutants found in sewage include oxygen-depleting substances (referred to as Biological Oxygen Demand or BOD), suspended solids and nutrients – each of which carrying a heavy ecological toll when released into a fragile ecosystem

We went through the topics mentioned in the Environment Textbook. We came across this interesting and necessary project for pollution-free Earth- The Lakes receives more water from sewage than natural water flow.

It was a great help from the internet for searching for information on topics like the importance of water, lake, water resources, pollution by factories.

OBSERVATIONS :

With all its natural riches, the Great Lakes region has seen tremendous economic growth in the past century. Currently, over 35 million people live in the Great Lakes basin, with almost half drawing their drinking water directly from the Great Lakes.5 On both sides of the Canada-United States border, sprawling cities, major industries, mining, and manufacturing all place a heavy burden on the Great Lake’s delicate ecosystems.

In a recent report, more than 150 scientists and natural resources managers assessed the state of the Great Lakes ecosystem.6 Their report highlighted a long list of serious threats to the health of the Great Lakes, including the invasion of alien non- native species, loss of natural habitat, and toxic contamination from various sources in both countries. Add on the impacts due to climate change, which is altering precipitation patterns throughout the Great Lakes basin in addition to the overall warming,7 and one can conclude that the Great Lakes are under assault by us.

In the past three decades, multi-billion dollar investments to upgrade municipal sewage treatment systems in the Great Lakes basin have we observe that clue to sewage rainy rivers, tanks, lakes etc are polluted these cause great damage to everything we survive in that water and use that water many rivers and lake receive more sewage water that its natural water. In India many rivers are their as Ganga etc. the Ganga is the best example for the polluted water. The water of Ganga has been polluted.

So large that we cannot use it if we use that water it is harmful to our life & it causes a lot of diseases in the human body. The Ganga is considered as a goddess in India but the people in polluting Ganga more. After a few years, that river will be damaged. As this pollution will be continuing there will be no water for drinking and the people has to suffer a lot of loss and life will be very difficult.
