Most water pollutants are eventually carried by rivers into the oceans. In some areas of the world the influence can be traced hundred miles from the mouth by studies using hydrology transport models. Advanced computer models such as SWMM or the DSSAM Model have been used in many locations worldwide to examine the fate of pollutants in aquatic systems. Indicator filter feeding species such as copepods have also been used to study pollutant fates in the New York Bight‚ for example. The highest toxin

Water is a very important part of our lives. We use it for nearly everything – drinking‚ food preparation‚ laundry‚ dishes‚ hygiene‚ etc. We swim in it‚ boat in it‚ and play in it. In fact‚ 70% of our world is covered in water. However‚ 97% of that water is saltwater and we are unable to drink it‚ leaving only three percent of the planet’s water drinkable. But two percent of the world’s freshwater is frozen in glaciers and ice caps. Only one percent of this freshwater can be used and consumed. Therefore
