Water is uniquely vulnerable to pollution. Known as a “universal solvent,” water is able to dissolve more substances than any other liquid on earth. It’s the reason we have Kool-Aid and brilliant blue waterfalls. It’s also why water is so easily polluted. Toxic substances from farms, towns, and factories readily dissolve into and mix with it, causing water pollution.
Categories of Water Pollution
Groundwater
When rain falls and seeps deep into the earth, filling the cracks, crevices, and porous spaces of an aquifer (basically an underground storehouse of water), it becomes groundwater—one of our least visible but most important natural resources. Nearly 40 percent of Americans rely on groundwater, pumped to the earth’s surface, for drinking water. For some folks in rural areas, it’s their only freshwater source. Groundwater gets polluted when contaminants—from pesticides and fertilizers to waste leached from landfills and septic systems—make their way into an aquifer, rendering it unsafe for human use. Ridding groundwater of contaminants can be difficult to impossible, as well as costly. Once polluted, an aquifer may be unusable for decades, or even thousands of years. Groundwater can also spread contamination far from the original polluting source as it seeps into streams, lakes, and oceans.
Surface water
Covering about 70 percent of the earth, surface water is what fills our oceans, lakes, rivers, and all those other blue bits on the world map. Surface water from freshwater sources (that is, from sources other than the ocean) accounts for more than 60 percentof the water delivered to American homes. But a significant pool of that water is in peril. According to the most recent surveys on national water quality from the U.S. Environmental Protection Agency, nearly half of our rivers and streams and more than one-third of our lakes are polluted and unfit for swimming, fishing, and drinking. Nutrient pollution, which includes nitrates and phosphates, is the leading type of contamination in these freshwater sources. While plants and animals need these nutrients to grow, they have become a major pollutant due to farm waste and fertilizer runoff. Municipal and industrial waste discharges contribute their fair share of toxins as well. There’s also all the random junk that industry and individuals dump directly into waterways.

Ocean water
Eighty percent of ocean pollution (also called marine pollution) originates on land—whether along the coast or far inland. Contaminants such as chemicals, nutrients, and heavy metals are carried from farms, factories, and cities by streams and rivers into our bays and estuaries; from there they travel out to sea. Meanwhile, marine debris—particularly plastic—is blown in by the wind or washed in via storm drains and sewers. Our seas are also sometimes spoiled by oil spills and leaks—big and small—and are consistently soaking up carbon pollution from the air. The ocean absorbs as much as a quarter of man-made carbon emissions.
Point source
When contamination originates from a single source, it’s called point source pollution. Examples include wastewater (also called effluent) discharged legally or illegally by a manufacturer, oil refinery, or wastewater treatment facility, as well as contamination from leaking septic systems, chemical and oil spills, and illegal dumping. The EPA regulates point source pollution by establishing limits on what can be discharged by a facility directly into a body of water. While point source pollution originates from a specific place, it can affect miles of waterways and ocean.
Nonpoint source
Nonpoint source pollution is contamination derived from diffuse sources. These may include agricultural or stormwater runoff or debris blown into waterways from land. Nonpoint source pollution is the leading cause of water pollution in U.S. waters, but it’s difficult to regulate, since there’s no single, identifiable culprit.
Transboundary
It goes without saying that water pollution can’t be contained by a line on a map. Transboundary pollution is the result of contaminated water from one country spilling into the waters of another. Contamination can result from a disaster—like an oil spill—or the slow, downriver creep of industrial, agricultural, or municipal discharge.

My best friend is Lan. We have known each other since we were 10 years old. However we became best friends when we were at grade 7. At that time I was very bad at English and it was who helped me improve my English. Now she lives with her parents in Nguyen Trai street.
If I were to describe how she looks I would say she is very pretty. She has long black hair a straight nose and a small pointed chin. She is quite slim. She doesn t like to dress up so I usually see her wearing jeans and a T - shirt. She has a very nice personality and a wonderful sense of humour but she can also get a little depressed from time to time. I can always count on her to be honest and to give me the best advice.
What I like about Lan is that she has same hobbies with me. We both enjoy singing karaoke reading comic books and going shopping. We like going to the cinema but sometimes can t agree on which movie to see. In addition since I am better in Maths and Chemistry and she is better in English and languages we can always help each other if we get confused about a difficult homework assignment. We are so lucky that we get along so well. I hope that our friendship can last long.
3 .Nowadays English is one of the most mean to speak with anyone over the world so it is spoken by any person in any natiọn Most of secondary shool, English is a compulsory subject so student must learn it.

My dream is a teacher of English in order to teach for my student to know more about people and countrys of England. I hope my dream will become true and so do you

In our country, there are quite lots of different festivals every years. However, I think Tet festival is the most typical festival for most Vietnamese people. Though we can live or work far from our family, we still try to get together at Tet. Tet festival often occurs in late January or February.
It is a good chance for us to have days off and have time to visit relatives or friends for giving good luck and the best wishes to each other. For some people who are rich, they can go on a trip somewhere in Viet Nam or in foreign countries to enjoy Tet festival
i like country life. because people in the countryside are more friendly than those who live in city
in the countryside, the enviroment is very fresh and it have many trees. my mind is better: not busy, peaceful.
many people say that: " the country life is very boring!" but i don't think so. i think although the countryside doesn't have many means of the entertainment but we can play traditionnal games..
in the city, people always want to work and work, they want to have much money. so, sometimes they forget many interesting things in their life.
in the countryside, you can become another one : you are better, happier anh care of everybody. here, people are a big family, if you are sad, they are sad with you. if you smile, they smile with you
only thing i want to say " i love country life and my Hanam province, forever"

2. Which english speaking country do you know about?
The UK is one of the English speaking countries. The UK consists of England, Wales and Scotland. The UK also includes Northern Ireland. The people here live very peaceful. There are many festivals, but I like the cake festival most.
On the third day of confession, the day before the Vegetarian Festival Lent in the United Kingdom, people usually celebrate pastry festivals.
On the fourth century, Christianity held a 40-day vegetarian Lent, and this was the period when people were eating and running. Often people eat their brakes and enjoy themselves before the Lent begins. And the third day of confession is often called the feast of feasts because of the banned fat on Lent must be consumed. Everyone took out the eggs and the daily food left in the kitchen to make delicious cakes.
The origin of the festival is that each mouthful of a woman is making pastries when the bell rings. In order not to be late, she just had a cake and ran into the church. Since then, people in this area have pastry festivals.
However, this run is only for women. You will follow the path of knowing beforehand into the church and have to throw hot cake in hand at least 3 times. Whoever runs to the final destination will be the winner.
It is also an extremely beautiful country and quite famous.

I came to Hanoi on an autumn day, and my first feeling was the feeling of a peaceful space, not like in Ho Chi Minh City. That feeling was overwhelming all my soul when I was walking along Nguyen Du Street and enjoying the Milk flower. Why was it so beautiful here? In the early winter night, in slightly cold spread hoarfrost, sitting on the bank of Thien Quang Lake, whether at the other side, I still smelt its perfume. I walked along the street and dropped myself in a sweet smell of Milk flower, the wind blew my hair, and I felt so great.
Milk flower on the streets of Hanoi goes deeply inside the memories of Hanoi people and all visistors who have come to Hanoi. It also goes into the music, the poetry, movies. Those are some good ways to introduce Milk flower to everybody. For me, means of communication such as internet or TV are the best ways to introduce Milk flower for all over the world. It is simple when everyone looks at all wonderful pictures or images of Milk flower, they will want to come and enjoy it. In Japan, they have cherry blossom, in Netherlands, they have tulip…How can we know about it? That is all thanks to means of communication. We must let them know that in Hanoi, we have Milk flower. Therefore, the things we need to do now are we should have a website about Milk Flower with pictures, clips, songs, poetry in many languages (if we can)… or we can hold more activities which relate to Milk flower. We must have some more activities to advertise this kind of flower. That was what I think when I saw Milk flower for the first time. I love Hanoi. I love the early cold winter nights with Milk flower’s smell. I hope Milk flowers will be grown more on Hanoi streets. Milk flower is a precious gift that nature gives to us, especially to Hanoi, our beloved capital.
Today, I will lecture about the country of Japan. the reason that I love this country as comics and cuisine. Japanese comics attached to my childhood. I spent a private space to collect them. There are many famous series like doraemon cônan. Japanese culinary culture is very rich and rich nutritional value. the Japanese usually use fresh ingredients to make dishes. and in particular they favor fish and vegetables. I would like to try the noodles or shushi in Japan. I have read in comics, look at them seems very appealing. Life in Japan is a high-quality life and modern. The Japanese are very careful and always demanding in all things. they are very hospitable and always help others, especially for international students. VA cuoi cung 1 other reason I love for a landscape that is. for example Mount Fuji or cherry. the famous temples in Kyoto.
