Groundwater Pollution

Water that gets collected under the surface of the Earth is referred as groundwater and the sources of this water are sleet, rain, hail, snow etc. Water collected on the surface of the land travels downwards till it reaches a saturation point due to the gravity. This water fills the space between rocks and soil particles and this is referred as the

saturated zone

. The top portion of this zone is known as

water table

and these levels vary from season to season. The level of the water is high in spring and low in summer. Like any other water groundwater is more susceptible to pollution and the following article provides you with groundwater pollution sources and prevention.

About Groundwater

Groundwater is usually connected to lakes, streams and rivers. Water gets exchanged continuously between the groundwater and surface water. Groundwater is considered as the natural source of water and it can be used for both drinking and household purposes. This water is used by most of the population in the United States and in many places it is used for irrigation purposes of crops and in factories.


Change in the various properties of this water can be due to several reasons like contamination by foreign particles, microbes, hazardous substances and chemicals. Groundwater pollution is considered as the major form of water pollution. The following are a few other sources which cause this condition.

  • Natural Sources

    : These are less harmful than that of the hazardous chemicals which are usually generated by human beings. This condition is usually caused when the chemicals present on the surface of the ground travel all the way to the groundwater and it largely depends on hydrology, chemical type and soil porosity.

  • Industries

    : These are considered as the major source that can result in causing pollution of groundwater. Industries require plenty of water in order to manufacture different kinds of chemicals. This polluted water is then recycled back without treating it properly. Industrial wastes dumped into the ground can also result in causing this condition.

  • Agriculture

    : Pesticides, chemicals and fertilizers used for plants contribute to groundwater pollution. Most of the residential areas generate organic and microorganisms compounds which are responsible for this condition.


  • This condition cannot be prevented as there are various reasons that are not practical. Every person can contribute in various ways in order to prevent groundwater pollution.
  • Waterproof storage of chemicals such as detergents, medicines, agricultural chemicals and paints, proper disposal of waste and avoiding leaching can help in lowering this condition.
  • Installation of proper septic systems which are cleaned regularly will help in lowering this condition.
  • It is always recommended to minimize the risks of this condition by conducting public awareness programs about the ways and importance of lowering this condition.
  • Government should take necessary steps to make sure that every individual participates actively in lowering pollution.
