Water Pollution--A Global Problem

Paper Summary:

This paper examines water pollution, the adverse effects of added materials to a body of water and the effect it has on the environment. It analyzes how the impact of water pollution can be observed altering all living things in the world, most notably human life and how certain measures can be taken to prevent further destruction and reverse damage already done. It outlines the main causes of water pollution such as petroleum contaminants and natural sediment and looks at the dangers posed to humans by certain main pollutants.

From the Paper:

"There are two main ways in which water can be polluted: point sources and non-point sources. Points sources of water pollution occur when harmful materials are disposed of directly into a body of water. Non-point sources of water pollution occur when harmful substances are indirectly disposed of into a body of water (MacMillan, 1982). Examples of non-point sources are septic fields leaking into waterways, or pesticides from a crop being carried into a waterway with precipitation (MacMillan, 1982). Non-point sources are much more difficult to monitor and control than point sources. There are many types of contaminants that pollute waterways. For the most part, water pollution is made up of organic matter (eroded soil, branches, grass clippings, farming waste)(Britannica, 2001). "
