Hi everybody. My name is Nhi. I am from HKH school. Today I will introduce about water pollution. It is evidently clear that water is one of the prime elements responsible for life on earth.I. Facts that:1.Ocean pollution: Pollution in our oceans is a serious problem. One of the most popular places to dump garbage is the ocean. People thought that since the ocean was so large the garbage would just sink to the bottom, but they were wrong. It’s enough to harm and kill people. 2.Underground: Materials from the lands surface can move through the soil and end up in the groundwater.3.Rivers Lakes Freshwater: Most fresh water pollution is caused by the addition of organic material which is mainly sewage, but can also be food waste or farm effluent. II.Reasons of water pollution: a.Industrial Waste: Chemical waste products from industrial processes are sometimes accidentally discharged into rivers.You see dead fish floating on the river or notice that the water is discoloured and smelly any one of the following forms of industrial waste.b.Fertilisers: Farmers put fertilizers and pesticides on their crops so that they grow better. But these fertilizers and pesticides can be washed through the soil by rain, to end up in rivers. Fertilizers can cause groundwater pollution.

Hi everybody My name is Nhi I am from HKH school Today I will introduce about water pollution
* It is evidently clear that water is one of the prime elements responsible for life on earth.
I Facts that:
1 Ocean pollution: Pollution in our oceans is a serious problem One of the most
popular places to dump garbage is the ocean People thought that since the ocean was so large the garbage would just sink to the bottom, but they were wrong It’s enough to harm and kill people
2 Underground: Materials from the land's surface can move through the soil and
end up in the groundwater
3 Rivers / Lakes / Freshwater: Most fresh water pollution is caused by the
addition of organic material which is mainly sewage, but can also be food waste
or farm effluent
II Reasons of water pollution:
a. Industrial Waste: Chemical waste products from industrial processes are
sometimes accidentally discharged into rivers.You see dead fish floating on the river or notice that the water is discoloured and smelly any one of the following forms of industrial waste
b Fertilisers: Farmers put fertilizers and pesticides on their crops so that they grow
better But these fertilizers and pesticides can be washed through the soil by rain,
to end up in rivers Fertilizers can cause groundwater pollution
For example: Fertilizers from farms after rains can also carry pollution to groundwater
Fertilizers can cause people and animals to become ill, kill plants, and have adverse
c. Human: The main causes of water pollution are most often manmade and caused
by increasing industrialization and human activities
For example: Every day, we cook, do laundry, flush the toilet , wash our cars , shower and do many things that use water
III Solutions:
a. Industrial Waste: Make a sewage system
Factories use the wastewater treatment process in some steps: mechanical,
biological and advanced wastewater treatment
b Fertilisers: - Start looking at options of composting and using organic manure
instead
- use natural fertilizer for plants
Farmers are encouraged to access to new farming process
Trang 2c Human: - Use recycled papers to help save trees
- Avoid buying plastic
Supermarkets should use papers instead for wrapping up the products
IV Conclude:
If you want to help keep our waters clean, there are many things you can do to help You can prevent water pollution of nearby rivers and lakes as well as groundwater and drinking water by following some simple guidelines in your everyday life
• Water pollution is a global, but nevertheless, a local issue !
• Think about the next generation !
• Get involved and help!
