Pollution is defined: “to make foul or unclean; dirty,” according to the American College Dictionary. Water pollution occurs when water is harmfully affected due to large amounts of wasted materials added to the water. As water becomes unfit for its intended use, it is then considered polluted. There are two types of water pollutants that exist, point source and non point source pollution. Point Source Pollution occurs when harmful substances are released directly into a stream of water. ... One example of this type of water pollution is when fertilizer from a field is carried into a stream by rain, in the form of run-off which in turn affects aquatic life. Point source of pollution can be monitored and regulated through technology. ...
There are many different causes of pollution. ... Excessive growth of these types of organism’s clog our water way, uses up dissolved oxygen, and blocks light to deeper water. Eutrophication which is an aging process that slowly fills in the water body with sediments and organic matter. When the sediments enter a large mass of water, fish respiration become impaired, plant productivity and water depth become reduced. Sediments are minerals or organic matter deposited by water, air, or ice.
Three other forms of pollution are petroleum, radio active substances, and heat. Petroleum pollutes the water in the form of oil, which result from oil spills. The Exxon Valdez Oil Spill is a prime example of this type of pollution. ... Radioactive pollution comes in the form of nuclear power plants, and scientific use of radioactive materials.
