Due to these contaminants it either does not support a human use, such as drinking wateror undergoes a marked shift in its ability to support its biotic communities, such as fish.

Natural phenomena such as volcanoesalgae bloomsstorms, and earthquakes also cause major changes in water quality and the ecological status of water.

Water pollution is a major global problem. It requires ongoing evaluation and revision of water resource policy at all levels international down to individual aquifers and wells. It has been suggested that water pollution is the leading worldwide cause of death and diseases, [2] [1] and that it accounts for the deaths of more than 14, people daily.

An example is directly discharging sewage and industrial waste into the ocean. Pollution such as this occurs particularly in developing nations. Large gyres vortexes in the oceans trap floating plastic debris. Plastic debris can absorb toxic chemicals from ocean pollution, potentially poisoning any creature that eats it.

This results in obstruction of digestive pathways, which leads to reduced appetite or even starvation. There are a variety of secondary effects stemming not from the original pollutant, but a derivative condition. An example is silt -bearing surface runoffwhich can inhibit the penetration of sunlight through the water column, hampering photosynthesis in aquatic plants.

Groundwater pollution Main article: Groundwater pollution Interactions between groundwater and surface water are complex. Consequently, groundwater pollution, also referred to as groundwater contamination, is not as easily classified as surface water pollution. The distinction of point vs. Analysis of groundwater contamination may focus on soil characteristics and site geology, hydrogeologyhydrologyand the nature of the contaminants.

Causes of groundwater pollution include: Categories of pollution sources Surface water and groundwater have often been studied and managed as separate resources even though they are interrelated.water pollution pollution of the water in rivers and lakes Introduction of foreign substances to a water source, either toxic to life forms or creating an oxygen demand, depriving indigenous life forms of oxygen and resulting in their death.
