There are many sources of pollutants in water, including agriculture, industry, transportation and incineration.1 Water has also been used for many years as a media of waste discharge.2 Water pollutants can be transported over long distances, may be found in remote areas and can even be found in the water many years after the substance has been banned.1 The level of pollutants present in water bodies is most commonly judged against set environmental quality standards (EQSs) that vary among different countries.
