Water Pollution
Interesting Facts
~Pollution in China alters the weather in the US.It takes just 5 days for the jet stream to carry heavy air pollution, from China to the US.Once in the atmosphere over the US, the pollution stops clouds from producing precipitation.
~Fourteen billion pounds of garbage (mostly plastic) is dumped into the ocean every year.
~Canada has 10 most polluted rivers- some of which are Petitcodiac River, Okanagan River and Eastmain River.
~Cruise ships are a major source of water pollution.They produce over 200,000 gallons of sewage which is mostly released in the ocean.Apart from that, they are also causing at least 35,000 gallons of water contamination due to oil spill.
~The water pollution is getting severe from year to year.Each year, US water is filled with 1.2 trillion gallons of industrial waste, storm water and untreated sewage.
What is Water Pollution?
Water pollution is the contamination of water bodies. Once the substance is contaminated it becomes impure and has to be treated several times.The pollutant is the main source of impurity such as hazardous chemicals, human waste and trash.

~Underground storage leakages
~Atmospheric deposition
~Global Warming
~Eutrophication

Different Contaminants
Marine Dumping
has become an enemy to the living creatures and organisms in the ocean.The garbage in the ocean can serve a more severe effect on the eco system than any toxins.This is because the time the trash takes to decompose in the water varies and can cause harm along the waves.;)
Cardboard-2 weeks
Newspaper-6 weeks
Paper-2-5 months
Cigarette butts 1 to 12 years
Leather Shoes- 25 to 40 years
Nylon fabric- 30 to 40 years
Foam-50 years
Aluminum-200 years
Plastic Packaging-400 years
Glasss- 100,000,000 years
Pollution of Fresh Water

Today humans have the largest impact on our water cycle and water quality.Yet some of our interactions may leave the human race with a thirst that cannot be quenched.
A 2012 study shows that 2,200 children die everyday as a result of drinking filthy water.While many, or most people all around North America willingly pollute our water without a second thought. Although, our polluting ways affect potable water around the world. Most do not realize the affect pollution is having on our water system.
Rain water picks pollutants from the atmosphere and then falls to earth as a different formation such as acid rain, thus increasing the water pollution problems.Also, when precipitation falls, street litters (cigarette butts, plastic bottles, candy wrappers etc.) can be picked up by overland flows and can be released into the sewer, which ends up in rivers, streams, lakes and oceans.Fertilizers, chemical spills, septic tanks and sanitary sewer; overflows can contaminate ground water.All these sources are connected to the water cycle.It's also possible that a segment of a water body could be lightly impacted, while the other segment is severely impacted.Tidal influence, river flow rate, and/or shape of a water body can determine how quickly it recovers from the impact of pollution.
Pollution of groundwater
Sewage
is a term used for
waste water
that often contains faeces, urine, and laundry waste. Regularly the waste is disposed into the ocean, this can become a larger concern if chemicals or pharmaceutical items are flushed. Untreated sewage water can not only contaminate the water but the environment as well.
Underground storage leakages
are leaks that pipes produce when the piping material wears off or if there is a corruption in the ground. Underground storage tanks (UST) are likely to carry substances such as petroleum and if the substance is exposed it could cause harmful contamination to its surrounding soil and groundwater.
Industrial waste takes a huge role in pollution on earth, from producing toxic gases to polluting our water systems.
Pollutants from industrial sources
Asbestos-Causes asbestosis,mesothelioma,lung cancer, intestinal cancer and liver cancer if the fibers are inhaled
Lead & Mercury-a non-biodegradable substance,causes health and environmental problems
Nitrates-increased use of fertilization washes nitrates from the soil into the water, causes eutrophication
Oils-oil does not combine with water it then creates thick top layer stopping and sunlight to pass through for the marine plants
Petrochemicals & Sulphur-toxic to marine life
Radioactive waste
is the leftover by-products from a nuclear substance. It can cause harm to the aquatic habitat
Oceans are polluted by oil regularly by oil spills,shipping (ex.cruise ships),run-offs and dumping.Oil spills block light from photosynthetic marine plants and suffocates marine animals.
Atmospheric Deposition
is caused by the main source which is air pollution.
1.Water particles mix with carbon dioxide, sulphur dioxide and nitrogen oxides with created a weak acid.
2.Air pollution is developed by the air particles absorbing the gas fumes, forming a stronger acid.
3.When precipitation occurs, it is polluted by the gases and form acid rain.
4.Once acid rain pollutes the lakes and rivers, the animals, organisms and creature become affected.
Global Warming

is the process of the global temperature rising due to the effect of the greenhouse gases and fossil fuels. The warming of the earth will disrupt one source, however that will then effect the things dependent on it.
Septic tank
:a tank that allows the sewage to decompose using bacteria
Primary Sewage Treatment
:screens, sedimentation tanks, filters and apparatus are used to extract large floating objects
Secondary Sewage Treatment
: a biological process that removes bacteria and contaminant growths the most effectively.

Reducing Surface water Pollution
Bottled Water
Bottled water is essentially tap water
Produces 1.5 million tons of plastic waste per year
Production involves 47 million gallons of oil annually
25% of the H2O in one bottle is tap water
1.DO NOT LITTER!
2.DO NOT DISPOSE OF TOXIC! PRODUCTS DOWN THE DRAIN!
3.DO NOT USE THE TOILET AS A GARBAGE CAN!
4.DO NOT DIPOSE OF MEDICATION OR PILLS DOWN THE TOILET!
5.BE AN ACTIVE PARTICIPANT IN CONSERVING WATER!
Polluting our freshwater supply is very risky because we have 3%, and about only 1% is accessible! Things that humans do such as dumping garbage or using factories that produce pollutants or chemicals
all
reach the water. Also runoff from farm lands,factories and even food packaging all contribute to this major concern.
Pollution of Saltwater
We have a large supply of salt water, however it's not potable enough because of the high salt content. If we can't drink the saltwater than what good use do the oceans provide for us? Well the oceans are a great use for traveling from continent to continent quickly. It also carries a great amount of fish that aids in the fishing industries.The oceans have a large part in the water cycle because the ocean is the prime source for evaporation because of the vast amount.
Our main source of potable water is groundwater.Groundwater can be contaminated from different sources, particularly man-made such as gasoline, oil,road salts and various chemicals.It infiltrates into he ground eventually reaching the water supply and contaminating it making it unfit for human use.
