What are the factors that affect the color of river water?
What are the factors that affect the color of river water? Dissolved organic matter, such as humus, peat or decaying plant matter, can produce a yellow or brown color. Some algae or dinoflagellates produce reddish or deep yellow waters. Water rich in phytoplankton and other algae usually appears green. Soil runoff produces a variety of yellow, red, brown and gray colors.
Is Brown river water clean?
NO river water is considered safe to drink, ESPECIALLY large rivers that pass through cities. The Rio Plata (means 'silver river'), the 'Blue Danube', the Seine, Thames, Mississippi, Ganges, Yellow River, - all are a nice brownish colour partly due to the waste and surface drainage they still contain.
