I want the answer for ground water contamination by crude oil point of view
Well,
Pollution is particularly dealing with waste materials which harm our air, water, soil, and space. It occurs when the contaminants reach an alarming number.
Regards
In simple terms contamination can be considered as a subset of pollution. The term "Pollution" is applied to larger scale as compared to "contamination" which is applied to smaller scale .

The answer given by Vishwanath Sharma ManoharMayum is quite satisfactory. Pollution is the sum total impact of all the contaminants present.
Pollution is inferred when the level of concentration is high enough to impair water quality and capable of producing an observable effects. But if the level of concentration is still within permissible or acceptable limits then it is contamination. That is to say that if contamination continues unabated then it results to pollution.
Answering this question comes back to the difference between pollutant and contaminant: A pollutant is a contaminant that has degraded the state of the environment. This refers to the answer of Vishwanath Sharma ManoharMayum, so a question of scale.
Contamination: It is the presence of a foreign material in any other material. But it doesn't do harm. Example: A cup of water contains few drops of grape juice. we might say the water is not pure.
Remember a pure substance means, which is 100% of its own composition and structure.
Generally, a contaminant is an undesired material although it does not have to be harm.
Pollution: It is the presence of any substance or material that may cause a harmful effect on human, animal and plant. If their is no harm, then it is called contaminant.
Example: A cup of water contains few drops of poison or chemicals. we might say the water is not pure.
When a material is found where it should not be that is contamination. Pollution is concerned when any chemical, biological and physical change in water quality that has a harmful effect on living organisms or makes it unusable for agriculture: eg:
-The massive quantity of pollutants produced by > 6 billion humans, their machines, plants, animals
-The limited supply of fresh liquid water into which most water-destined pollutants are discharged
-The growing number of ‘technological pollutants’ released into the environment, i.e. manufactured synthetic materials.
The substances that cause water pollution are called pollutants
Dear Sir
pollution means that pollutants presents in large quantities in the environment , and these pollutants caused large risk for human and ecosystems , whereas the contamination means the pollutants found in small quantities and it may be within the permissible value.
- Pollution means the contamination or alteration of the physical, chemical or biological properties of water including change in their temperature, taste, odor, density, or any other characteristics, or any component of the environment, destroys or causes injury or harm to public health or to domestic, commercial, industrial, agricultural, recreational or other useful activity.
- Contamination is the undesirable effluence of something by a different ingredient. Simply, it is the existence of an external elements in any other element though it doesn't do harm.
- Precisely: Pollution-the level of concentration is sufficient to degrade water quality and proficient of generating an apparent effects. Contamination- the level of concentration is within threshold or acceptable limits.
Contamination is simply the presence of a substance where it should not be or at concentrations above background. Pollution is contamination that results in or can result in adverse biological effects to resident communities. All pollutants are contaminants, but not all contaminants are pollutants.
Contamination is the presence of something external to some other thing which can be regarded as host. The host here does not suffer any harm. For example, debris(external thing(s) occurring in river, ground, or ocean water (host). Also,the occurrence of some level of iron content(Fe2+) in ground water would have no adverse effect on ground water for human consumption.
Pollution is the presence of an external thing(s) with adverse effect(s) on the other thing or environment (host) it or they are occurring in. For example, some bacteria even at very low levels compared to iron content, occurring in ground water can have adverse effects for human consumption and be pollutant(s). Also and typically, oil pollution is regarded as spread of crude oil on the environment (land, water and atmosphere) arising from spill(s)which can cause adverse effects on the environments and thus their inhabitants.
Extrinsic foreign particles present in the geosphere, Biosphere and hydrosphere that should have not presnet normally where as presence of contaminants in the above sphere that polute the enviornment and biodegrade the envioronment. All pollutants are contaminants but not vice versa.
The groundwater pollution definition: an introduction of certain pollutants into the groundwater which reduces the quality of groundwater, making its use very limited, or in some cases impossible. Many different chemicals, and various synthetic products are usually the main causes of groundwater pollution. This term, pollution, is used to refer to those agents or activities that cause significant damage to the environment and drastically damage the ecosystem. In other words, pollution is the presence in or introduction into the environment of a substance or element that has dangerous or toxic effects.
In the case of grounwater contamination, it can be supported by the environment without stopping the general chemical cycles and life.
In other words, all pollution is contamination, but not all contamination is pollution. Pollution is a high-grade contamination.
Hi,
The groundwater contamination is dependent on the characteristics of the waste or leachate, that is, its volume, composition, concentration of the various constituents/substances, time rate of release of the contaminants from source, the size of the area from which the contaminants are derived, and the density of the leachate/source.
After its getting more and more contaminants in specific area then, we can say pollution in that specific area. Pollution makes severe biological changes in the environment and community.
Pollution is caused by pollutants, contaminants may or may not cause pollution. Contaminants means addition of any foreign/external material into the soild/liquid/gas medium. Similarly as answered by Dr. Ramdhan, All pollutants are contaminants, but not all contaminants are pollutants.
Yes, contamination is part of pollution for example soil contamination is part of soil pollution.
If any undesirable material present in a system which does not cause any harm to the system that usually termed as “Contamination” .Whereas when that undesirable material cause harm to the system that regarded as “Pollution”
In majority cases, contamination is unspecified but pollution is specific.
Contamination is the existence of a or combination of unwanted substances beyond normal regular existence. Pollution is contamination that consequences a negating biological/ ecological effects on the present resident communities. All pollutants are contaminants, but not the reverse.
Contamination is the existence of unwanted substances. Pollution is when the contaminant causes HARM to organisms or infrastructure. Therefore you can have a contaminated environment without it being polluted but you cannot have a polluted environment without it being contaminated.
I have a similar opinion with Dr. Abhijit Mitra
Contamination is the presence of foreign material in any other material. But it doesn't do harm to the properties of the material.
But pollution is the presence of any substance or material that may cause a harmful effect on humans, animals, and plants. It can affect the properties of the material too.
Contamination: Introduction of an undesirable organism, regardless of the kingdom to which it belongs, whether it is a chemical pollutant, a pathogen, a pest or an invasive species in a previously uninjured biotope (François Ramade, 2008).
Ramade, F. (2008). Dictionnaire encyclopédique des sciences de la nature et de la biodiversité. Dunod.
Pollution: Direct or indirect introduction, as a result of human activity, of substances or heat into the air, water or soil, likely to harm human health or the quality of aquatic ecosystems or ecosystems terrestrial, which cause damage to material goods, deterioration or hindrance to the enjoyment of the environment or to other legitimate uses thereof: European Directive 2000/60 / EC of October 23, 2000.
Pollution’ means the direct or indirect introduction, as a result of human activity, of substances or heat into the air, water or land which may be harmful to human health or the quality of aquatic ecosystems or terrestrial ecosystems directly depending on aquatic ecosystems, which result in damage to material property, or which impair or interfere with amenities and other legitimate uses of the environment.

Pollution is the fact to find a physic-chemical agent in a media beyond the admissible level and that can be harmfull to living organisms in the media. Contamination is when a material is found in a media where it should not be. In this case, thé treshold limit is not déterminant factor.
Contamination is the presence of foreign material in any other material. But it doesn't do harm to the properties of the material.
But pollution is the presence of any substance or material that may cause a harmful effect on humans, animals, and plants. It can affect the properties of the material too.
Both pollution and contamination are due to the presence of foreign substances in the systems they are present, but their degree of effect varies.
Pollution is mostly associated with environment. It deals with waste materials which cause harm to air, water or soil. Substances responsible for pollution are called pollutants. Pollutants are of two types- (1) Biodegradable- such materials can be degraded by biological agents, lasts for short time and cause little effect in the environment, and (2) Non biodegradable- these materials can survive for long time and can cause serious problem. Pollutants can disturb the ecosystem.
Contamination is due to the mixing of external materials with the original materials. Such extraneous materials are called contaminants. It occurs in certain bodies or substances.Contaminants may be chemical or biological. Contaminants can be processed for purification.
Introduction of any unwanted material in an environment is called contamination, but if the contamination do harm to the environment then it is called pollution.

Contamination is simply the presence of a substance where it should not be or at concentrations above background; the substance that was introduced by man into the environment by any means. Pollution is contamination that results in or can result in adverse biological effects to resident communities; the pollutant may be induced by man or may be present in the natural environment.
All pollutants are contaminants, but not all contaminants are pollutants.
Dear dr. Omar Ali Al-Khashman
Thank you for your useful information.

Dear Munira Nasiruddin
Thank you for your useful contribution.

Dear Ahmed,
You have many correct answers, and some not so good.
The correct ones are:
Contamination is the presence of a substance in an unusual concentration (a spoonful of sugar in your coffee).
Pollution is the presence of a substance in an unusual concentration such that environmental harm is caused (a spoonful of arsenic trioxide in your coffee).
Many incorrectly use the term pollution where anthropogenic influences are at work and the term contamination when natural influences are at work, thereby losing the distiction between harm and no harm. So, unhealthily high (>1.5 mg/L) concentrations of F in groundwater in the African Rift Valley (which caused brittle-bone disease in humans) is regarded by some as 'contamination', when in fact it is pollution.
Hi,
Many responses to your question, in my point of view "Contamination means somethings are the one component in that environment that might be harmful or might be not, however, if the contamination is over the limit or acceptable level or over the standard, that might be pollution.
Hello Dr Ahmed N. A. Hamdan
Pollution is the degradation of the environment by substances (natural, chemical or radioactive).
Contamination is the medical term used to designate the invasion of a living organism or thing by pathogenic microorganisms.
Contamination means the presence of a substance where it should not be or at a levels/concentrations higher than the background concentrations. Contaminants are defined as inputs of alien and potentially toxic substances into the environment; not all contaminants cause pollution, as their concentrations may be too low. While pollution simply means contamination of a medium which can result in adverse health effects to individuals exposed. Pollutants’ are usually anthropogenically-introduced and have harmful effects on the environment. Logically, it could be explained that all pollutants are contaminants, but not all contaminants are pollutants.
Contamination is simply the presence of a substance where it should not be or at concentrations above the background. Pollution is contamination that results in or can result in adverse biological effects to resident communities. All pollutants are contaminants, but not all contaminants are pollutants ( Chapman, P. M., 2007).
The Contaminant can be simply defined as a specific portion of matter or body that is not wanted there and can cause contamination due to its presence in this product, body, or the specific region of the environment. The pollutant is a material consisting of a little waste. This can cause pollution in different parts of the environment such as soil, water or air.
