The non-point sources of water pollution are those which arrive from different sources of origin and are usually scattered or spread over large areas.

Biological pollutants can travel through the air, are often invisible, and may be a major cause of days lost from work or school, and of doctor and hospital visits.

There are three categories of bioremediation techniques: .

Pollution is defined as the presence of impurities or pollutant substances in sufficient concentration levels, causing harmful effects on human beings, animals, plant life or material resources when exposed for a sufficient duration of time, thus reducing the quality of life in the environment.
