Water is very essential to life and so high attention is paid to the aquatic activities, with regards to some natural water that have a changed color from the colourless appearance of water,can be attributed to many factors which the main Two are
Scientific facts : Natural light is actually made up of a numbers of different colors associated with different wave lengths within the light spectrum.Think of the multiple colors of light when refracted by a prism. The color we associate with anything is the range of light waves that is reflected back to our eyes by the molecules that comprise the entity. We don’t see the colors of light that are absorbed.When it comes to pure water, blue light is reflected while other colors of light especially reds, are absorbed.Factors such as minerals, soil runoff and sediment, and even algae bloom (Coccolithophore) can cause water to vary from its natural color of blue.The most common cause for water to change color is minerals. When a rock is weathered down over time, the minerals from the rock are dissolved and small pieces are released into the water causing different colors.Iron, manganese, and calcium carbonate from limestone all common minerals that can cause water to range in color from red and orange to green and blue.Sediment and soil runoff can also change water’s color ,sometimes as a temporary color change after storms and sometimes permanently if the river constantly carries lots of sediment. Erosion from river banks brings soil into the river, changingthe color. After heavy storms, many rivers run brown from all the runoff flowing into the river. Clay can cause rivers to be murky brown, or blue .
