Water Pollution Causes and Effects

Water Pollution:

Water Pollution Water pollution occurs when energy and other materials are released into the water, contaminating the quality of it for other users.

Causes of Water Pollution:

Causes of Water Pollution Sewagefrom domestic households, factories and commercial buildings Sewage that is treated in water treatment plants is often disposed into the sea.  Sewage can be more problematic when people flush chemicals and pharmaceutical substances down the toilet .

Causes of Water Pollution:

Causes of Water Pollution Dumping solid wastes and littering by humans in rivers, lakes and oceans. Littering items include cardboard, Styrofoam, aluminum, plastic and glass.

Causes of Water Pollution:

Causes of Water Pollution Industrial waste from factories, which use freshwater to carry waste from the plant into rivers, contaminates waters with pollutants such as asbestos, lead, mercury and petrochemicals.

Causes of Water Pollution:

Causes of Water Pollution Oil Pollution caused by oil spills from tankers and oil from ship travel.  Oil does not dissolve in water and forms a thick sludge.

Effects of Water Pollution:

Effects of Water Pollution Groundwater contamination from pesticides causes reproductive damage within wildlife in ecosystems . Sewage, fertilizer, and agricultural run-off contain organic materials that when discharged into waters, increase the growth of algae, which causes the depletion of oxygen.  The low oxygen levels are not able to support most indigenous organisms in the area and therefore upset the natural ecological balance in rivers and lakes . Human-produced litter of items such as plastic bags and 6-pack rings can get aquatic animals caught and killed from suffocation. Water pollution causes flooding due to the accumulation of solid waste and soil erosion in streams and rivers. Oil spills in the water causes animal to die when they ingest it or encounter it.  Oil does not dissolve in water so it causes suffocation in fish and birds .
