Essay on Problems of Water Pollution Text

Jonathan Friesen - Writing Coach

We rely on clean water to survive, yet right now we are heading towards a water crisis. Changing climate patterns are threatening lakes and rivers, and key sources that we tap for drinking water are being overdrawn or tainted with pollution. Dirty water is the world's biggest health risk, and continues to threaten both quality of life and public health in the united states. It picks up toxic chemicals, dirt, trash and disease carrying organisms along the way.

Many of our water resources also lack basic protections, making them vulnerable to pollution from factory farms, industrial plants, and activities like fracking. This can lead to drinking water contamination, habitat degradation and beach closures. Nrdc is working to protect our water from pollution by: drawing on existing protections in the clean water act. And working to ensure that the law's pollution control programs apply to all important waterways, including headwater streams and wetlands, which provide drinking water for 117 million americans improving protections to reduce pollutants like bacteria and viruses, which threaten americans' health and well being and establishing new pollution limits for top problem areas, such as sources of runoff and sewage overflows. в» learn more about the obama administration's clean water protection rule from more severe and frequent droughts to unprecedented flooding, many of the most profound and immediate impacts of climate change will relate to water. More than one third of all counties in the lower 48 states will face higher risks of water shortages by mid century as a result of global warming. Other impacts will include sea level rise, saltwater intrusion, harm to fisheries and more frequent and intense storm events.

To help communities prepare, nrdc is creating tools that help the public and government officials to better understand and anticipate the water related impacts of climate change at a state. We also promote ways to reduce wasted energy resulting from inefficient water collection, treatment and distribution. When you think of problems in the world today, water pollution isn't one that would normally come up.

Water pollution, by definition, is the contamination of streams, lakes, underground water, bays, or oceans by any substances harmful to living things. All living things contain it, live in it, and most need it to survive, so water pollution is a big problem, if not the biggest. If severe, the pollution can kill off birds, fish, and any animals that use the water source. The major water pollutants are chemical, biological, or physical materials that degrade water quality. Pollutants can be classed in to eight categories, each of which presents its own set of hazards. Oil and chemicals derived from oil get into the water mainly by means of accidental spills from ships, tanker trucks, pipelines, and leaky underground storage tanks. Many petroleum products are poisonous if ingested by animals, and spilled oil damages the feathers of birds or the fur of animals, often causing death.

Pesticides and herbicides are toxins that are used to kill of unwanted animals and plants. These may be collected by rainwater runoff and carried into steams, rivers, lakes, and even into the ocean. Nitrates, a pollutant often derived from fertilizer runoff, can cause methemoglobinemia in infants, a potentially lethal form of anemia that is also called blue baby syndrome. Heavy metals, such as copper, lead, mercury, and selenium are another group of toxins that pollute the water as well as the rest of the environment.

The source of many of these pollutants are industries, automobile exhaust, mines, and even natural. Many of today’s water ecosystems and drinking water are being polluted and destroyed as we speak. There are many types of water ecosystems such as oceans, rivers, lakes, and ponds witch provide homes to many different organisms.

There are overwhelming factors that contribute to the problems of water pollution such as sewage, radioactive wastes, improper disposal of trash on land, and careless beachgoers. These are all significant problems that people do not realize until all of the damage is done. There are very few methods of controlling this pollution and more need to be developed in order to try and control these problems immediately. Here is your essay on controlling water pollution! science provides many practical solutions to minimize the present levels at which pollut­ants are introduced into the environment and for remediating cleaning up past problems. In our everyday lives, a great deal can be done to minimize pollution if we take care to recycle materials whose production creates pollution and if we act responsibly with household chemicals and their disposal.

Additionally, there are choices we make each day that can also affect the quantity of pollutants. Made with polluting dyes, many of which are released into the ground­water at municipal landfills. Whether we choose to drive to the corner store rather than walk or ride a bicycle will determine how much we personally contribute to acid and hydrocarbon emissions to the atmosphere and ultimately to global fresh water supplies.

Gogreenacademy.com/wp content/uploads/water pollution habitat.jpg since water plays such a vital role in life on the earth, good quality water is a precious resource. The quality of the water affects the use we make of it, but the reverse is also true. This circular process indicates that the traditional habit of discharging untreated sewage and chemical wastes directly into rivers, lakes, estuaries of oceans for even­tual assimilation into the environment is no longer acceptable either technically or morally. The explosion in human population and industrial activities, and the rate at which new chemicals and products are being developed and used pose a global environ­mental threat.

the approach to controlling pollution depends on the following: i. The type of pollutant whether it is degradable or persistent whether it is metal or a pesticide or a pcb, and so on. The source whether it comes from an industrial pipe or from a farmers field or from atmosphere. Measures taken to protect water quality include the following: ideally, polluting contaminants should be prevented from entering the water. Specific causes which should be controlled to prevent water quality degradation are air pollution, agricultural run off and seepage containing the residues of fertilizers, pesticides and other chemicals, industrial pollution, either directly from the facility, or indirectly from the leaching of chemicals from landfills, or pollution from average households in the form of improperly treated municipal sewage. At the most, in some circumstances, pollutants can be allowed only in low concentrations. In deciding how to prevent or to regulate water contamination, a number of questions have to be asked, including the sources, amounts and effects of various substances, their fate after entering the water, the concrete possibility to prevent substances to reach the water body or to remote them by treatment.

Obviously, prevention is the only regulation method for those chemicals, which cannot be removed by water treatment methods from entering the water system. Technology can be used in many cases to reduce or eliminate sub­stances that may be harmful to the environment. Sewage treatment plants, properly operated and maintained, are the means of removing many toxic substances from wastewater and returning the treated water to a river or a lake without causing harm downstream. All of us, as individuals, can do something to protect the water quality by being responsible consumers. Many daily normal activities as simple as rinsing dishes in the kitchen create wastewater that is contaminated to some degree.

Once this water enters the sewer system, it must be treated in a sewage treatment plant. These facilities are never 100 per cent effective, which means that some water quality deterioration remains after the treatment process. So choosing non hazardous products, reducing the use of some chemicals, respecting the recy­cling programs of municipalities, ensuring a proper disposal of waste are important behaviours to maintain water quality. It may appear clear, but there are really millions of microscopic pollutants floating in it. Approximately 70% of the earth's surface are covered by water water is a very dynamic system, any change in its normal content could affect local, regional, and eventually worldwide water. Oil is one of the world's biggest pollutants oil is usually spilled or leaked from land or rivers and flows from them to the sea or ocean.

The more direct form of oil pollution is when ships transporting oil leaks or the ship crashes. Oil can also ruin shores it can was up on them and become tar like lumps some coat fur of animals and can effect their heating system. Also some oil can find its way into other sources causing hazardous water to be consumed. There are particles called hydrocarbons that settle or are washed down by rain from the air to the ocean. A toxic waste can be quickly passed along the food chain and can cause various problems. Sewage and industrial wastes introduce chemical pollutants like pcb, ddt, and sevin. Syringes, with all the various diseases going around that can be passed by needles that is a scary though.
