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 PollutionGroundwater
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.

4. Yes , there is / No, there isn't ( cái này cũng phụ thuộc vào suy nghĩ của bn nốt )
5. I should use cloth bags instead of plastic bags because :
Cloth bags are the best choice, and, as with anything, it's best if these are made from renewable, non-toxic and low-impact materials.Simply substituting disposable plastic bags with disposable paper bags is not a good solution.
Plastic bags are made from a non-renewable resource, petroleum, and they never fully break down. Even when they do break down, they simply become tiny flakes of plastic. In a landfill, it's likely they'll never break down as the landfill is compacted so tightly. While they can be recycled, contamination is a big problem, and recycling also takes energy and resources, and results in a lower quality plastic.

Keeping the school campus neat and clean is very important for all the students because a school is a place to study and learn. If the physical environment is not an attractive one, then studying and learning become less pleasant and the concentration of the students will be hampered. To keep the school campus neat and clean the students have to do some certain works. Firstly, in every class the students can make a class forum or group and the leader of the forum can divide the works. There are different works in the school campus. According to the instruction of the leader the students will continue the work. Some students of a forum can arrange of garbage and rubbish in waste disposal containers, take care of the gardens and trees. Similarly, another group can keep the plants well-trimmed, mow the lawn, and trim the grass around the borders. Other group can rake the fallen leaves, keep the statues well-polished, mop and vacuum the floors and carpets inside. Some can clean the walls, windows and other surfaces. To keep the campus always neat and clean the students can make some rules permanently both inside and outside of the classroom. Firstly, students should not spit in the class, drop litter in the class. Secondly, they have to use the bin for trash and keep the desks and chairs in place. At the time of performing the works they can get any help from their class teacher and other teachers. In this process the students can keep their school campus neat and clean.
