Water Pollution

Water pollution has become one of the largest environmental problems throughout the world. With many countries, both modernized and third world alike, being greatly affected by this problem it is sure to remain a prevalent topic in political and environmental debates for quite some time. Questions about the causes, results, statistics and solutions to water pollution and the problems it causes should be placed here.

What government agencies a responsible of water pollution?

Two answers. Responsible for it happening: all of them. Pollution is inevitable at least on a small scale and you are looking at a million grains of sand, but not necessarily the same contribution each by a long shot. It is also the job of everyone to reduce, reuse, and recycle.

As for the reduction and cleanup? You are looking at the Environmental Protection Agency (EPA). They do good work given their funding, but again, no one person, or even one thousand alone can fix the current issue with water pollution.

Is tonic water harmful to heart patients?

I think so. We were two guys who drank lots of tonic water iso. clean water in a hot climate. Both got problems with heart rate after two weeks. Inceased and even irregular puls. You got something there.

Where could a 1998 Mercedes C230 be leaking when it rains very hard to cause water to be standing on the floor on the passenger side when the water is not coming from the roof?

fire wall or ac heating system. check cabin filter for water damage. filter is located on pass side under glove box.there is a clip the cover comes down now slide filte clamp off and pull filter out.

What happens if your water pump goes out?

There will be no water pumped into your engine to cool it, then you might need a new engine.

Is non-chemical or non-salt water purification better?

ecosmarte is a non chemical and non salt water water purification for swimming pools

What may be the cause of a swishing water sound in the dash board when slamming on the breaks?

Check radiator fluid when engine is still cold but running add if needed and fill resevoir. Never open a radaitor cap on a hot engine only qualified mechanics should ever attempt this.

What is Underground injection?

Underground injection is the process of pumping waste water underground (hence avoiding the cost of purification). The US EPA (Environment Protection Agency) has strict laws about what and where. See the link below.

If you don't recycle what will happen?

If you do not recycle

global warming would be worst and also the temperature would rise because that produces greenhouse gases and also would kill animals and humans. Also it can cause odurs and smells to your home and to the earth

What is food pollution?

The ancestral Inuit diet is based on fish, sea mammals and game, all of which are high up the food chain. But air- and sea-borne pollutants are lodging in the Arctic and infiltrating these traditional foods.

"Certain pollutants, such as chlorinated pesticides and PCBs, find their way to the Arctic by air or by sea from as far away as India and Egypt," said Laurie Chan, a toxicologist with the Montreal-based Centre for Indigenous Peoples' Nutrition and Environment (CINE), which conducts research on northern nutrition and consumption.

Substances known as persistent organic pollutants, or POPs, are now banned in North America but still used in developing countries. Harmful agricultural pesticides evaporate from farmland and are carried across oceans and continents by wind to the frozen Arctic, which scientists believe acts as a sponge for a wide range of pollutants. Chemicals then make their way into the food chain and settle in animal fat, an Inuit staple.

"Native people consume much animal fat," said Chan, "especially in mammals who in turn eat a lot of fish." The contaminants accumulate and become more concentrated the higher they go up the food chain towards human consumption.

At the same time Inuit who had switched to processed foods -- perhaps spurred by television advertising -- are trying to return to the eating habits of their ancestors.

But a recent report by the Canadian Polar Commission, a government-funded watchdog that advises on northern issues, warns that contaminants in traditional foods could reach dangerous levels in the next few decades unless trends are reversed.

Medical statistics have already shown an increase in obesity and kidney disease among native people of the North, which some experts believe may be traced to the shift towards store-bought food.

Another report recently found that levels of contaminants in northerners who eat marine mammals could be harmful to the unborn. A six-year survey by the National Contaminants Program, which groups government ministries and native organizations, warns that memory and learning abilities could be affected in the womb because of chemicals which have accumulated in the mother's body.

In addition to pollutants carried by air and sea, traditional food in the North is being threatened by the remains of abandoned military bases that dot Canada's Arctic shores.

Crumbling buildings, rusting metal drums and twisted towers are the sorry reminders of radar sites which North America once considered vital to its defence strategy. The bases gradually became obsolete and were quietly closed down back when little was known about the carcinogenic nature of asbestos and PCBs. These substances are now filtering into the environment, adding to contamination from far-off sources. Radioactive wastes from the North Sea are also contributing to the pollution.

Whatever the health warnings, the Inuit have made it clear they won't stop eating the nutritional food that has sustained them for thousands of years.

"If you're told not to eat your food, or told not to consume parts of the animals, that does real damage to the intricate connections that we have to our foods and our animals," said Norma Kassi, environmental coordinator for the Council of Yukon First Nations.

"We consider them to be a part of us just as we are a part of them, so that breaks a tie, and will hurt a culture much more than anything else. You can't remove us from our food systems -- it just can't be done."

While there are isolated areas where contamination is already significant, Kassi says most of the food is still safe.

"Yes, there is contamination in our food, but relatively it is still very, very good," she said. "We want to encourage more use of it."

One thing all experts agree upon is the need for caution and for more research before raising the alarm or reaching a verdict on short-term food safety. But the long-term picture looks grim and scientists say danger could be just around the corner if the situation is allowed to deteriorate.

To mark its concern about transboundary pollutants, Canada is spearheading international efforts to ban the use of POPs. At risk are the food chain and the quality of life of some 125,000 circumpolar Inuit spread out across Canada, Russia, Alaska and Greenland.

Unlike many other environmental threats, specialists contend food contamination can be beaten if it is taken seriously enough, soon enough, by those who control the purse strings.

What are the pros and cons of the Wing T offense?

One of the main benefits of the Wing T offense is that it causes misdirection, and is difficult to defend. A con is that it takes several linemen who have the athletic ability to pull.

How do you fix the interior air director on a 1998 Safari when it only delivers air to the windshield regardless of control position?

A vacuum line is broken.

Often the small vacum line that goes from the top L/H side over to the R/h fender and attaches to rear heater selnoid will melt as it passes over the intake manifold. It get hot and brittle and eventually breaks.

What are the effects of water pollution in the Philippines?

Water pollution causes a lot of problems for humans, animals and the environment. Pollution levels are on the rise again despite stricter laws and regulations by the Environmental Protection Agency (EPA). One of the recent water pollution issues affecting Americans is the closing of beaches as a result of polluted beaches and beach water. All across the United States many beaches on the oceans, bays and the Great Lakes were closed due to pollution being washed onto the beaches from neighboring cities and towns in the form of sewage, debris and other pollutants. Sewage spills and overflows nearly tripled in occurrence in recent years and many closings were blamed on sewage. Because of the recent water pollution issues regarding beaches, a Beach Protection Act was recently passed in the United States House of Representatives and is awaiting action in the Senate. This bill would increase federal funds for the purpose of detecting sources of beach water pollution and cleaning them up. People can do their part in keeping the beaches and beach water clean by not littering, picking up trash and wastes, maintaining their septic systems, cleaning up after their pets, putting plastic pants on babies and properly disposing of toxic household items as well as used motor oil and boating wastes.

Another one of the very important recent water pollution issues affecting the quality of water comes from giant livestock farms and feedlot. These farms house hundreds of thousands of animals such as pigs, cattle, and chickens in relatively small areas and produce a huge amount of waste. Pollution that results from these massive feed lots seriously affects the health of humans as well as fish and the ecosystems around the farms. One of the recent water pollution issues in regards to the giant feedlots revolves around the huge amounts of nitrates that are dumped into the groundwater. High levels of nitrates in the drinking waters has a devastating effect on humans and leads to an increase in methemoglobinemia, also called blue baby syndrome, which can kill infants. Animal wastes also contain disease causing pathogens. This is a very one of the most serious recent water pollution issues that we face as a nation.

Another very serious one of the recent water pollution issues is the aging sewer system that leak sewage and wastes into the ground waters. It is estimated that every year enough sewage is leaked into the water systems around the world to fill the Empire State Building and Madison Square Garden. In some counties in the United States sewers discharge untreated sewage into creek, rivers and lakes where children swim and play. Treatment plants are not able to keep up with the flow of sewage and more than one billion gallons of sewage gets discharged into the environment as a result. Rain water also causes the sewers to overflow and sends them right into nearby rivers and streams affecting drinking water as damaging health to humans and animals alike.

What are the negative and positive effects of radium?

the positive aspects of radium is glows in the dark and added another element to the periodic table of elements the negative aspects are it gives cancer and if ingested your body will believe its calcium causing weakening of the bones and something called radium jaw were the jaw falls of from being weakened from the radium.

What happen if you don't recycle?

Recycling could cause disease due to unsanitary conditions, which would be caused by overflowing landfills. Trees would be cut down and areas would be plowed to make room for landfills. Creatures like rats and cockroaches would be common due to all the trash. We would run out of resources like metal, plastic and paper because they would all be thrown away instead of recycled, causing global havoc and anything from wars to extreme economical depression because of lack of important unrenewable resources.

What is contaminant fate?

A similar term is "contaminant transport". It means the path that a contaminant moves from its beginning to its final resting place, and all the physical, chemical and biological processes that might change it on its journey.

How does garbage buried in a landfill cause pollution in a water supply?

Garbage (domestic trash, plant waste , food scraps, oils, diapers, etc) essentially forms a disgusting tea bag under the surface of the soil. As water percolates through this mixture the dissolvable materials wash out, oil and toxics are washed out and bacteria are allowed to enter the mass and rot the organics present. The leachate (essentially the "tea" created by this "teabag) contaminates the water in the underground water supply or escapes into surface water. Aside from the water related waste, the site can produce methane gas, a powerful greenhouse gas and fire hazard.

This can be prevented by creating a proper landfill. This would include waterproof covers and bottoms made out of clay, plastic liners and leachate collection systems. A properly designed, utilized and maintained landfill does not pollute.

What is an equalization tank in a sewage treatment plant?

Equalization tank for wastewater treatment refers to a holding tank that allows for equalization of flow. An equalization tank may also be used as a staging area where chemicals, activated sludge, or other agents are added into the waste-water treatment process.
