Enlgish 2 ( Water Pollution ) Research Proposal

Enlgish 2 ( Water contamination ) - Research Proposal ExampleWater pollution refers to the human-induced changes to pee quality. Scholz contends that contamination of ground water, rivers, lakes, wetlands, estuaries, and oceans flush t vegetable oilet peril the health of humans. Contaminated water has threatened the health of humans for centuries and continues to pose the same threat take down today.Water is crucial for the welfare of the humanity and it is the quality of water that matters, not the quantity (Myllyntaus, 2005). Water occupies much than 71 percent of the earths surface but only 2.5% of it is fresh water, meant for human consumption. Again, 1 percent of this fresh water is divided into lakes (61%), atmosphere and soil moisture (39%) and the streams make up for little than 0.4 percent (Frank, McClure, Press & Walsh, 2001). The streams including the rivers constitute the smallest percentage of river distribution, most of the water for human consumption is provided by them. crapulence water accounts for even less because much of the fresh water in undrinkable (Myllyntaus, 2005). About 20 percent of the fresh water is stored in fresh water form and this is not a speedily renewable natural resource. Rainwater is the only naturally renewable form of water.Water pollution can be divided into two categories point-source pollution and non-point-source pollution. When contaminants are discharged from a discrete location, as the 1989 Exxon Valdez oil spill, it is known as point-source pollution (Scholz, 2003). Non-point-source or diffuse pollution refers to all other types of contaminants that polluter the water body. Acid rain is an example of non-point-source pollution.Water pollution poses threats to human health in different ways. The pollutants autograph the body via skin exposure or when drinking water or contaminated food is consumed direct (Scholz, 2003). Mercury has been detected in fish tissues that are found in contaminated water bodi es and
