why is river water often a brown colour

After heavy storms, many rivers run brown from all the runoff flowing into the river.

Where does our water come from? We will give you the answers.Lucky for us all, our drinking water is almost always clear (very low turbidity).

The amount of dissolved oxygen in a stream or lake can tell us a lot about its water quality.Below are multimedia items associated with water color.Once in a while, you get a glass of water and it looks cloudy; maybe milky is a better term. Algae affect not only the health of a river but also the color. So, color in our water does matter when it comes to drinking it, as well as in water for other home uses, industrial uses, and in some aquatic environments.If you have ever drunk water containing a bit of iron in it, you would know from the metallic taste left in your mouth. Read on to investigate water color in the environment.It may be true that a bit of color in water may not make it harmful to drink ... but it certainly makes it unappealing to drink. Water that is blue has a very low amount of dissolved particles in it.Factors such as minerals, soil runoff and sediment, and even algae can cause water to vary from its natural color of blue.The most common cause for water to change color is minerals. And, if you have ever drunk "pure" water, such as distilled or deionized water, you would have noticed that it tasted "flat". Another example would be the cup of hot tea your grandmother has in the afternoon. No data point selected.

Observe the glass of water for a minute. Take our Water Properties True/False Quiz and find out.Water is nature is never really totally clear, especially in surface water, such as rivers and lakes. Algae consume nutrients from the water along with dissolved oxygen causing negative effects on the ecosystem of the river. Water full of dirt and grime might work fine for a tomato plant but would you want to drink it? Well water often contains naturally occurring minerals such as sulfur or iron ore. The cloudiness might be caused by the water in the pipes being under a bit more pressure than the water in 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. Dissolved chemicals in drinking water can be less than desirable. Water rich in phytoplankton and other algae usually appears green. Here are ten ways you can help reduce your water... The color caused by algae can vary from a dark green to almost a reddish color. Light is very critical for the growth of aquatic plants and colored water can limit the penetration of light.

Transparent water with a low accumulation of dissolved materials appears blue.

We are taught growing up that water is blue, but some rivers are black, brown, emerald blue, green, or even blue-green. Although water can contain contaminants, which are usually removed by water-supply systems, the plus side is that the water you drink likely contains a number of dissolved minerals that are beneficial for human health.

The presence of large amounts of iron can turn your water a brown or reddish-brown color. The water you see every day contains dissolved minerals and often suspended materials. First, you won't find truly pure water in a natural setting. Some algae or dinoflagellates produce reddish or deep yellow waters.

The apparent color is the color of the water when looking at it without removing any suspended and dissolved particles.True color is the color of the water after the suspended particles have been removed.

An example of dissolved substances is tannin, which is caused by organic matter coming from leaves, roots, and plant remains (picture below on the left). Where there is water there is life, and where water is scarce, life has to struggle or just "throw in the towel."
