Define Water Pollution
How does one define water pollution? Different individuals have a different interpretation of water pollution. This explains the myriad water pollution definition. There are also various scholars and researchers that have elaborated the concept of water pollution according to their own understanding. In simple terms water pollution is the release of foreign matter into any water source be it oceans, lakes or swamps. The main pollutants include industrial waste, domestic sewage, silt-bearing run-off and soil erosion.
Water pollution has a negative effect on the overall environment as the quality of the water is reduced and the aquatic animals and plants subjected to danger. Water maybe directly or indirectly polluted by point sources and non-point source pollutants. Point sources pollutants refer to contaminates added into the water via a discrete waterway such as a ditch or pipe. On the other hand, non-point pollutants refer to diffuse contaminants that is, pollutants that are not released by a discrete source for instance nutrient or urban runoff.
Other individuals define water pollution as a state that interferes with the normal functioning of the aquatic ecosystem. This is as a result of accumulation of foreign matter to a level that overwhelms the ability of the water to absorb, recycle or break them down. This is because the deposited foreign matter is either suspended on the water, dissolved in the water or sank to the bottom of the water bed. These foreign matters may include variants that form acid rain, chemicals from pesticides and fertilizers, silt originating from soil erosion, industrial chemical and urban wastes, sewage, septic tanks runoff and livestock feedlots outflow.
The high amounts of organic matter present a favorable environment for a number of organisms that can make the human body very ill or worse. However, the biodegradable process of the algal uses up a high percentage of the oxygen in the water lowering the oxygen concentration to extremely low levels. Moreover, hydrogen sulfide and methane gases are released. This further affects the aquatic organisms that depend on oxygen for their survival. Furthermore, the water body is turned to a filthy foul-smelling mass of waste water.
On the other hand, many scientists define water pollution as change in the physical, chemical, radiological and biological content of the water. This change is usually harmful to its potential and intended uses such as swimming, fishing, waterskiing and the overall aquatic ecosystem. According to scientists the change in water quality is mainly addition of human-induced pollutants into the water either in their solid, liquid or gaseous state. The contaminants added adversely affect the content of the water for instance it favors the growth of water clogging substances such as algae.
Moreover, biodegradable substances change the turbidity of the water, make the water dark and convert the aquatic ecosystem to an anaerobic environment. Furthermore, the toxic contaminants create a health hazard to aquatic animals and plants. The direct exposure to these compounds affects their growth, reproduction, survival and disease resistance rate. Remember, this article does not restrict you to define water pollution as explained here in, there is a plethora of other elaborations that explain what water pollution is.
