The picture is in Minimata Bay in Japan it's very polluted there.

What is water pollution?

Water pollution is when waste, garbage, sewage, or other disgusting things go into oceans, lakes, ponds, or rivers. Some types of water pollution are: Chemical, Groundwater, Microbiological, Nutrients, Oxygen Depleting, Surface water pollution, and Suspended Matter. Those are the 7 types of water pollution.





What are some of the consequences for water pollution? Some of the consequences are  fish and other aquatic animals are dying from water pollution. When we pollute it kills many living organisms. Water pollution is really bad the Gulf of Mexico  had an oil spill and it was one of the largest oil spills in the world!!!



What can be done to help prevent nitrates from entering our water  supply?



     Nitrate is a natural chemical compound in all the ecosystems. It’s one of the chemicals that is essential to plants and animals. The ways that high nitrates hurt people is that you can get methemoglobin or blue baby syndrome which mostly happens to babies that are under 6 months, pregnant women and adults that have reduced stomach acidity it changes the methemoglobin. What happens to babies is that they get blue in the face and could have trouble breathing. The way that nitrates get into the water is that after a storm then nitrates wash into ponds and rivers. The safe level of nitrates is no more then10 mg/l for water in wells. you should never let infants have water that has 10mg/l.this is what you can do to prevent and and get nitrates out of your water you can boil the nitrates or you can blend the nitrates out or lon-exchange it takes another substance out called chloride or reverse osmosis which forces water down to a membrane and that filters out the nitrates and you can give a lab a 4-16 ounce plastic container with your well water in it. When nitrates get to low then bacteria turns nitrates into gasses such as nitrogen, nitrous oxide,and nitrogen dioxide.   









What  are some of the sources of water pollution?

Some of the sources of water pollution are :Sewage and Waste water, Marine Dumping, Industrial Waste, Radioactive Waste,  Oil Pollution, Underground storage leakages, Atmosphere Deposition, Global Warming, Eutrophication. Sewage and waste water comes from domestic households, industrial and agricultural practices, produce waste water.

Global Warming

Global warming is where the temperature gets too hot in water that it kills living organisms. The causes for this is burning fossil fuel, letting out greenhouse gases like carbon dioxide into the atmosphere.

Oil pollution

Oil pollution is deadly to aquatic animals, oil pollution comes ships and dumping. One of the worst oil spills came from the oil company in the Gulf of Mexico. Basically all of the oceans are polluted every day! Oceans and their aquatic life are under the threat of oil water pollution!

Sewage and Waste Water

    Sewage from households affect the cleanliness of the waters,  such as lakes and rivers. What’s normally in waste water is laundry waste, urine, and faeces. If you don’t treat your sewage water it can affect the community using it and cause sicknesses such as diarrhoea.



Marine Dumping

    Marine Dumping is when garbage and other wastes gets dumped in to Marine habitats. It kills marine life and other living organisms that thrive on that water source.when you dump the following, cardboard, newspaper, photodegradable packaging, foam. styrofoam,

aluminum, plastic rap, or glass takes 2 weeks to unknown years to degrade.



Radioactive Waste

    Radioactive waste is when nuclear waste from industreail, medical, and scientific companies use it then dump the leftovers into aquatic environment.It kills marine life,and it affects us to.



Atmospheric Deposition

    Atmospheric Deposition is when air pollution goes into water pollution. In the atmosphere there is 3 dioxides that create a weak acid. These dioxides are water particles that mix with Carbon Dioxide, Sulphur Dioxide, and Nitrogen Oxides.



Eutrophication

    Eutrophication is when the environment gets fertilized with nutrients. This can be a problem in marine habitat in waters such as oceans, lakes, rivers, and ponds. It can cause algal blooms. Fertilizers are often used for farming. When fertilizers run- off into nearby water they increase nutrient levels. This creates phytoplankton and they aren’t bad but they reproduce more rapidly which turns out to become an algal bloom. This bloom of algae disrupts natrual ecosystem functioning.

This pollution is in Liesbeek River Cape Town Andrew Massyn it looks gross in that water.
