The addition of sewage, industrial wastes, or other harmful or objectionable material to water in concentrations or in sufficient quantities to result in measurable degradation of water quality.
Pollution in the Lachine CanalCanada Water is typically referred to as polluted when it is impaired by anthropogenic contaminants. 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,   and that it accounts for the deaths of more than 14, people daily.
An estimated people in India die of water pollution related illness including waterborne diseases every day. For example, in a report on water quality in the United States in44 percent of assessed stream miles, 64 percent of assessed lake acres, and 30 percent of assessed bays and estuarine square miles were classified as polluted.
Nutrient pollution Surface water pollution includes pollution of rivers, lakes and oceans.
A subset of surface water pollution is marine pollution. Marine pollution Main article: Marine pollution A polluted river draining an abandoned copper mine on Anglesey One common path of entry by contaminants to the sea are rivers.
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.

It is a very important resource for people and the environment. Water pollution is any contamination of water with chemicals or other foreign substances that are detrimental to human, plant, or animal health.
Worldwide, nearly 2 billion people drink contaminated water that could be harmful to their health. Water pollution is mainly causes by wastage thrown into it, but it’s also can causes by chain reaction from soil pollution and air pollution.
Soil normally acts as a filter of underground water sources which is the root of water we drink, as the filter is polluted, no doubt that the water will also be polluted.
