All around the world, countries are fighting to keep their water clean. Whether it's streams, rivers, lakes, or the ocean, countries have taken great measures to maintain a high quality of water for both human consumption and as a key component to the environment. We deal with the pollution problems and then decide on ways to clean it up. This valuable resource is the key to survival. Both plants and animals depend on water for their growth, so the water must be kept clean. The major contributors to water pollution can be classified in three categories, industrial, agricultural and municipal.
Examples of industrial wastes that can contaminant bodies of water are oil spills, acid rain, and waste run-off from industrial buildings and factories. Oil spills, even though they do not happen that often, can spill millions of gallons of its crude oil cargo into the ocean causing long term damage. The oil spreads out over the surface of the water, creating a deadly coating. It kills fish and animals and washes on shores polluting the beaches, shutting them down to the public. Once the oil has contaminated the water, immediate action must be taken to clean it out of the water. The most common procedure is to contain the oil with oil absorbent plastic booms and then skim the oil off the top of the water. Waste or industrial run-off from factories can pollute streams that are near the place of discharge. Oils, inorganic minerals, and chemical compounds are the primary types of waste run-off. In the case of industrial run-off, there are three ways the water can be treated to solve the pollution problem before it ever reaches the water source. First, control over the discharge can take place at the point of generation within the plant itself. Second, the polluted water can be sent to water treatment plants before it is released into the surrounding water sources. Third, the waste water can be treated within the plant and recycled again, or...
