Iron Bacteria

The iron-loving bacteria combine iron and oxygen, producing dense masses of orange- brown slime in and around stagnant or slow moving water.

Why does Scottish water taste different?

This is why you may notice a difference when you travel to a different part of the country. Taste differences in water come from salts and the minute presence of specific metals such as iron, copper, manganese and zinc in the water. Some people are more sensitive to tastes and odours than others.

What stains a river brown?

Red, brown or tea-coloured (but otherwise clear) water is due to the presence of organic matter or plant pigments called tannins. The tannins actually 'stain' the water.

Is iron bacteria harmful?

Iron bacteria are of no threat to human health. They are found naturally in soils and water in low numbers and will thrive as more iron becomes available. However, the orange slime in the water or leaching from the shore is often considered to be an aesthetic problem.

Discolored water and trapped air are common occurrences after a water main break or other water system maintenance work.

What determines the color of a river?

It is not unusual for rivers to change colors, explained Gardner. They change all the time because of fluctuations in flow, concentrations of sediments, and the amount of dissolved organic matter or algae in the water. For example, yellow-tinted rivers are typically sediment-laden but low in algae.

Why is the Amazon River Brown?

Every day, some 1.3 million tons of sediment pour from the mouth of the Amazon River into the Atlantic Ocean. The abundance of sediment—bits of rocks, soil, and clay carried by currents or resting on the bottom—is what gives much of the main stem of the Amazon River its milky brown color.

Why does river water look black?

Black waters are more acidic, resulting in an aluminum concentration greater than that of the more neutral white waters. The major difference is the concentrations of sodium, magnesium, calcium, and potassium; these are very low in black waters.
