Taste And Odour

What is the clarity of pure drinking water? A natural setting does not provide really pure water, for starters. The water that you see on a daily basis comprises dissolved minerals as well as suspended elements in some cases. If you fill a glass with water from your tap, the water will appear colourless to you, which is fine for most practical reasons. When staring through a long column of water, it is easy to observe that the water is not colourless; even pure water is not colourless, but has a small blue tint to it. The blueness of water is not created by the scattering of light, which is what causes the blueness of the sky. Water’s blueness, on the other hand, is caused by the water molecules’ absorption of the red end of the visible spectrum. The absorption of light in water is caused by the way the atoms vibrate and absorb different wavelengths of light, to give it even more detail. 

Environmentally-friendly colours and water

Dissolved and suspended components are two types of components that might lend colour to water in your surroundings. A dissolved material such as tannin is produced by organic matter such as leaves, roots, and plant remnants, and it is an example of a dissolved substance (picture below on the left). Another example would be a cup of hot tea that your grandmother enjoys in the late afternoon. The hue of the water in the image below is most likely due to naturally dissolved organic acids, which are created when plant material is progressively broken down into microscopic particles that are effectively dissolved in the water over time. In the picture, even if you filtered out the tannin-water, the hue would most likely still be there. Floating material (seen above on the right) from a tributary that contributes very turbid water with suspended sediment (fine particles of clay) to clearer, but still coloured, water in the main stem of the river is responsible for the majority of the colour in the water you see around you. Particulate matter that causes natural waters to become coloured includes algae and suspended sediment particles, which are both fairly frequent. However, even if swimming in dirty water may not be pleasant, it has a different colour from the water that contains dissolved tannins in it in some ways. This is due to the fact that suspended matter may be filtered out of even the dirtiest-looking water through filtration. After being placed in a glass and allowed to settle for a period of days, the majority of the material will settle to the bottom (this approach is employed in sewage-treatment facilities), and the water will become clearer and less coloured as a result of the process. If a company required colour-free water for an industrial operation, it is likely that they would prefer sediment-laden water over tannin-colored water in order to achieve that colour.

Problems with odour and taste

If a taste or odour is present at all of the property’s water faucets, the source is most likely the main water supply. If it only happens with certain faucets, the issue is with the fixtures or pipes that supply those faucets. If the problem goes away after a few minutes of running the water, it’s most likely a problem with your home’s plumbing system. Running the faucet for several minutes, putting some water in a container, and then storing it in the refrigerator is the greatest strategy to remove taste and odour generated by your plumbing.

Installing a certified water filter is another option.

smells of petroleum, gasoline, turpentine, gasoline, fuel, or solvents: These scents are uncommon, but they can be dangerous.

Use the water sparingly. Your water supply could be contaminated by a leaking subterranean storage tank.

Iron or copper from the pipes may seep into the water, giving it a metallic flavour. Zinc and manganese, two less frequent metals, could also be a concern. If you’re worried, have your water tested by a professional lab or call your water provider. For a list of qualified labs, contact your local health agency.

Taste or odours of chlorine, chemicals, or medications: The taste or odour may be strong due to the addition of chlorine to the water or the interaction of chlorine with a build-up of organic debris in your plumbing system. This isn’t normally a life-threatening situation. If the taste or odour bothers you, get help from your local health department or water utility.

Sulphur odour, sometimes known as rotten egg odour: The odour could be caused by bacteria developing in your sink drain or hot water heater, or by naturally occurring hydrogen sulphide in your water supply. Put a small amount of water in a narrow glass, stand away from the sink, swirl the water around inside the glass, and smell it to determine the cause. If the water has no odour, bacteria in the sink drain is most likely to blame. If there is an odour in the water, it could be coming from your hot water heater. Your hot water heater has a corrosion-prevention element built into it. As the element deteriorates over time, it might emit a sulphide odour. A licensed plumber may be able to assess the situation. If the odour is really coming from the tap water and you’ve ruled out the drain and the water heater, don’t use it. Contact your water utility or a public health organisation in your area.

Mouldy, musty, earthy, grassy, or fishy odours can be caused by bacteria growing in a sink drain or organic materials such as plants, animals, or microorganisms naturally found in lakes and reservoirs during specific times of the year. Put a tiny amount of water in a narrow glass, stand away from the sink, swirl the water around inside the glass, and smell it to determine the cause of the problem. If the water has no odour, the sink drain is the most likely cause. If there is an odour, it could be the result of organic particles in your drinking water. Even at very low quantities, this substance can alter the flavour and fragrance of your drinking water, although being completely harmless.

A salty taste can be caused by high quantities of naturally occurring sodium, magnesium, or potassium.

Seawater may be seeping into your fresh water supply if you live near the seaside. This could be dangerous to your health. Contact your local health department or your water system.

Conclusion

High-colour water has a major impact on the growth of aquatic plants and algae. Colored water can reduce the amount of light that reaches aquatic plants, which is detrimental to their growth. An aquatic environment that cannot survive in a highly coloured body of water will be harmed in the long run, resulting in the ecosystem’s degradation. The presence of extremely dense algal bloom that remains suspended in water bodies can block light from reaching the water body and deplete the water body’s dissolved oxygen levels, leading to the development of a eutrophic state that can significantly diminish the amount of life in the water. When used at home, coloured water has the potential to stain fabrics and fixtures.
