Abstract
Water is a precious resource but not everyone is aware of it. More than 1 billion people are missing about 20 to 50 liters of clean water each day to cater for basic needs such as eating and bathing. The phenomenon of oil exploration ocean shipping and petroleum-contaminated wastes is one of the causes of water pollution. It is estimated that about 1 billion tons of oil are transported by sea each year. Part of this volume about 0.1 to 0.3 is thrown into the sea in a relatively legal way the washing of oil tankers with seawater. The shipwreck is relatively regular disposal of lubricant or accidental dropping gasoline. The permeation rate of petroleum is seven times that of water which will cause the groundwater to become contaminated. About 1.6 million tons of hydrocarbons are discharged by rivers of industrialized nations. From the above causes we see that human consciousness is the main cause of pollution of water environment. Resources are not endless with the exploitation of an indiscriminate wing rampant run for market economy benefits without the appropriate treatment the water pollution is a certain matter. The importance is inevitable if people are unaware of the importance of water for life in the near future the resources will be exhausted.
