Sometimes referred to as groundwater contamination, groundwater pollution is not as easily classified as surface water pollution, as contamination may not be easy to recognise. Groundwater, by it's very nature, is more susceptable to contamination from sources that may not directly affect surface water bodies. Groundwater can become contaminated by those drilling for oil or gas wells.
Groundwater may be polluted through a spill or ongoing realease of chemical or radionuclide contaminents into soil, polluting the aquifer below yet not the surface water body above. This is defined as a toxin plume, and as it travels it is defined as a plume front.
Analysis of groundwater pollution usually focuses on the soil characteristics, geology, hydrogeology, hydrolgy and the nature of the contaminants at the site.

What are the four misconceptions about ground water?
Misconception: Groundwater is a non-renewable resource. Groundwater is constantly renewed by passing from atmospheric or surface water to groundwater in the hydrologic cycle. Misconception: Water from springs is safe without treatment. Although flow through the ground does have a purifying effect on water by filtering sediment, bacteria, and certain chemicals, the purification effect is limited. Large concentrations of chemicals may be too much to be completely removed, and certain chemicals may not be removed by the ground at all. Some groundwater is naturally unsuitable for drinking because of the minerals it has dissolved from the rock through which it flows. Misconception: Groundwater and surface water are separate. Groundwater, surface water, and atmospheric water are intimately related through the earth's water recycling machine, called the hydrologic cycle. Water passes repeatedly through all three parts of the cycle. Misconception: Groundwater flows in underground rivers. Little groundwater flows in open channels beneath the surface. Most flows through fractures in the rock, through millimeter sized opening between layers, and between the grains of the rock.
What is groundwater erosion?
It is groundwater that is being eroded through a process.
What filters through the soil?
The answer is groundwater.:)
Groundwater is stored in and moves slowly through permeable rock called aquifers . in what zone is groundwater located?
Groundwater that is not otherwise fossil groundwater forms part of the "water table".
How does man extract the groundwater?
Through drilling wells
What environmental and social effects occur at each stage of cotton?
Cotton is considered as the dirties crop as it requires many hazardous insecticides and pesticides that harm both human beings and animals while being cultivated. They also contaminate the groundwater through over-use of these chemicals. Cottonseed and field trash is used as animal feed. The pesticides affect the cows and their products.
How could hazardous chemicals deposited in landfills eventually affect groundwater?
The seep into the ground (polluting aquifers that we use for drinking water) and to the surface and cause widespread environmental damage (harm to life on Earth).

Can pest aside cause pollution?
There are thousands of types of Pesticides, some of organic and natural sources and some synthesized chemicals like paralytics. The word pollution could be subjective, Atmospheric Pollution - Possibly through pesticides delivery system, CFCs Water System Pollution - Possibly, in the case of DDT and birds for example Soil Pollution - Possibly, in the case of chemicals that are not soluble
How chemicals get into the tissues of animals miles away from where they were used?
This happens in many different ways, many of which involve the food chain. Some chemicals pollute the air, affecting animals in a very large area. Animals that ingest the chemicals directly will often move great distances before dying, circulating them through the food chain. Most chemicals can also seep into the ground and make their way into surrounding plants, being passed up the food chain. Groundwater contamination is also a major human health hazard. The best example of such chemicals would probably be pesticides, some of which never break down and are still present in most animals despite being banned decades ago.
What is the difference between throughflow and groundwater flow?
Through flow is the horizontal movement of water through the soil zone. Groundwater flow is the movement of water through the bedrock, which is typically an aquifer
What happens to the groundwater?
it gose through the soil and rocks
How does man extract the groundwater?
Through drilling wells
What organic plants can you plant in your planter?
All plants have the potential to be organic. For something to be described as organic is must be grown without the use of pesticides, insecticides, growth hormones or GMO's, basically it must be grown without chemicals. As long as you do not spray the plants in you planter with pesticides/chemicals, do not use chemicals in the soil they are planted in, then they should be considered organic. However the standards for being registered as an organic farmer are much more complex and require certification through the USDA showing that the food being grown complies with the legal regulations.
