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.

Topic 1: Write about types of pollution.

P/s : Chi 1 cai o nhiem thoi ...

Nowadays there are a lot of types of pollution such as : air pollution, water pollution, visual pollution .... and noise pollution. Noise pollution is constant and loud sound. To measure the loudness, or volumn of sounds , people use a unit called a decibel. When a sound is louder than 70 decibels, it can cause noise pollution. Do you know that the noise from a vacuum cleaner or motorcycle can result in permanent hearing loss after eight hours ? The sounds of a concert are even more serious. Noise pollution can also lead to headaches and high blood pressure. If you are listening to music throughout headphones, and other people can hear it, it means the music is too loud and unsafe.

Topic 2 : Talk about natural diasters and ways to prepare for them.

Today, there are more and more natural disasters that most people affect. In my opinion, we can't prevent natural disaster but we can have some preparation for them. There are many types of natural disasters but typhoon is a popular in our country. Firstly, typhoon is a tropical storm with wind and heavy rain. When it strike, it can weak havoc across large areas and effect lot of life or extensive damage to property . Flood can be happened by long heavy rain and people also can be became homeless. Last year lots of people were seriously injure in a typhoon. Natural disasters are also very dangerous but we also have some simple preparation . The first step is learnt about the risk in your area and read the information about natural disasters on gorvernment site. Next, find out that the rescue and emergency workers advice. It 's also important that you put together emergency supply it and should include food, water, medicine, document, and some money. Finally , plan safe places to meet your family and get to know the evacuation routes and shelter. In short, everyone sholuld protect environment to reduce this natural disasters.

3) Talk about ways of communication now and in the future.

Communication is a neccesary for eberyone. In present , there are three basic forms of communication: verbal, non-verbal and multimedia.

First, verbal ( meeting F2F) is a important way of communication help you success. I like hanging out with my friends and my friends and when I meet F2F with them I feel very confident. It explains why I can speak English easily. Let ' s try! You will have a great time. Secondly, you have a different thing to say non- verbal ( using signs ) will be a good choice. For example, you make your mother sad , you can use a sign to say ' sorry ' to her. Thirdly, with develop of science and technology , many multimedia appear such as video chatting , emailing,... You can know more information despite you still stay at home. But in the future, we can use telepathy or holography. Telepathy uses a tiny device place into our head. We will be communicating just by thought over the network. Holography will help us in our work. Even though, I prefer to chat with my friends. Life is more meaningful that way !

I have an unusual hobby: carving eggshells. I started this hobby four years ago after getting a carved egg from my dad when he came back from Japan. It's amazing that something as fragile as an empty eggshell can be made into such a beautiful piece of art. I was so amazed that I learned how to carve them myself from the internet. I find carving eggshells a little difficult but so interesting and useful. The feeling of accomplishment when I finish a piece is absolutely awesome. This hobby also helps me be more patient and careful.

Van Mieu (The Temple of Literature) was constructed in 1070 during Ly Thanh Tong's dynasty. Its original purpose was to honor Confucius. In 1076, the first university of Vietnam called Quoc Tu Giam (The Imperial Academy), was established within this temple by Emperor Ly Nhan Tong. That's the reason why the complex has the name of Van Mieu – Quoc Tu Giam up to now. Initially, Quoc Tu Giam was the school for princes and children of royal families and then expanded in the following year to admit top students from around the country.

Nowadays, Van Mieu – Quoc Tu Giam is one of the most famous tourist destinations for both Vietnamese people and foreigners. It's also a place to celebrate doctorates and high ranking scholars of Vietnam. One special thing about this place is that there are 82 Doctors' stone tablets. They are tombstones with names and origins of 1304 doctors placed on the backs of stone tortoises. If you come here at the beginning of the year or in May, when many important examinations take place, you will catch sights of numerous families and students who come and pray for luck.

Van Mieu – Quoc Tu Giam opens daily from 8 a.m. to 5 p.m. and the entrance fee for each adult is 30,000 VND.

Last summer holiday, in order to escape the extreme heat of Danang city, my family and I decided to go to Dalat. We went there by bus.

When we got this mountainous and wonderful city, it was getting dark. We felt very excited because of the nice weather and the fresh air. We stayed in Hoa Hong hotel, a little but comfortable one in the centre of the city.

The next day we went shopping in Hoa Binh market and, caught some fresh air by sitting near the Xuan Huong lake. We had lunch in a nice restaurant near the garden of flowers. The food was delicious and cheap especially the vegetables. In the afternoon, we took a taxi to visit the Valley of the Love. How beautiful it was! The following day was for visiting Prenn Waterfall, the Than Tho lake and the Hills of Pine. Every spot has its own beauty, I could say which is the best. People are friendly and polite, especially young Dalat girls with their pink cheeks.

This wonderful holiday helped us to get rid of worries and trouble and gave us health and enthusiasm to resume work again. It was an interesting and unforgettable holiday.

In my free time I really like to draw, jump on / off the couch, and I also like spinning on the carpet on one knee. It's fun because if you spin VERY fast, you will just get thrown somewhere. Like you're flying! And I like making vids on my YouTube channel, and sharing
what I like to do, just like I'm sharing now. I really enjoy playing Sims, cause you can create your own world in Sims! I like to watch vids about bronze, bulls, and cakes (which is why I have this kind of name). I also like this app called iMovie, where you can make your own movies. I have a plush named Hedgy. And his last name is Hog. So he is a Hedgy Hog basically. Hedgy is the main actor of all of my movies. And do you know why I hang out with a plush so much? Cause he goes with me to school for about a month! Not that long, but it's enough to be a friend with a plush hedgehog. Me and Hedgy like eating pizza, cotton candy, and lemonade (We really like the pizza from Pizza Garden. The pizza there is fresh, italian, and it's REAL!). When I grow up, I wanna make a book called ''Diary Of Hedgy" and a book called ''Lamp Diary". And I'm planning to make a YouTube channel for Hedgy. Please reply if you like doing the same things I like to do! Ok, bye guys! (My fingers are SUPER tired of all of this writing!)
