It is a widely accepted fact that pure water tastes like nothing. If you recall your chemistry lessons from school, H2O is described as tasteless, and odourless. Yet, anyone who moved houses, or travelled enough knows that the taste of water changes from city to city, and ground water to river water, etc,. So what is the standard taste of water? And what contributes to the variation in water’s taste? Let’s find out.
What is the Standard Taste of Water?
Though pure water is supposed to be tasteless, finding such water is next to impossible. Water we end up drinking almost always includes minerals that come from sources like rivers and underground water which in varying degrees give the perception of taste. Further the taste water is also affected by factors like our taste receptors, temperature, carbonation, pH variations, etc,.
Factors Influencing Water's Taste
- Mineral Content
Minerals like calcium and magnesium, often found in natural water sources, significantly affect taste.
-
Hard Water vs. Soft Water:
Hard water, with higher concentrations of dissolved salts, has a distinct metallic taste. In contrast, soft water, with fewer dissolved solids, may taste flat. -
Other Minerals:
Potassium, sodium, and bicarbonate can also influence flavour. For instance, bicarbonate imparts a mild alkaline taste, while sodium can add a hint of saltiness. -
Total Dissolved Solids (TDS):
The TDS level, often measured in parts per million (ppm), indicates the concentration of dissolved minerals. A balanced TDS between 150-300 ppm is generally considered optimal for a pleasant taste.
- Source of Water
Tap water is often treated with chlorine or fluorine for disinfection which renders a chemical smell and taste to it.
Spring water from natural springs is rich in minerals which are absorbed from the surrounding rocks. It offers a fresh and mineral-rich taste.
Well water extracted from underground aquifers tends to be high in TDS (Total Dissolved Solids) giving it an earthy flavour.
- Storage and Distribution
Pipes and Tanks:
Metal pipes, especially older ones, can introduce a metallic aftertaste. Similarly, water stored in plastic tanks may pick up a slight plastic or chemical flavour.
Bottle Materials:
Bottled water stored in glass often tastes purer than that in plastic due to the absence of leaching chemicals.
- pH Level
The pH level of water, which measures how acidic or alkaline it is, can have a significant impact on taste. Water that falls within the neutral pH range (6.5 to 8.5) generally tastes best, as it’s not too sour or too bitter. However, water with a low pH (acidic water) can taste sour or metallic, while water with a high pH (alkaline water) often has a smoother, slightly "soapy" taste.
When to Seek Professional Water Testing
If your water consistently tastes off, it’s essential to have it professionally tested. A water quality test can detect contaminants, pathogens, and mineral imbalances that might not be visible to the naked eye. This can help ensure that your water is both safe and healthy to drink, especially if you notice an unusual taste or odour. Don’t hesitate to consult a water testing service if you have concerns about your water’s quality.
Improving the Taste of Your Drinking Water
Filtration Systems
Filtration systems are one of the most common and effective methods for improving the taste of your drinking water. Different types of filters can remove unwanted contaminants, minerals, and impurities that may be affecting the flavour of your water:
- Activated Carbon Filters: These are great at removing chlorine, sediment, and volatile organic compounds (VOCs), which can contribute to bad tastes.
- Reverse Osmosis (RO) Systems: These systems can effectively filter out a wide range of contaminants, including heavy metals, salts, and chemicals, resulting in purer, tastier water.
- UV Filters: While primarily focused on killing bacteria and viruses, UV filters can also improve the overall cleanliness and taste of water by removing harmful pathogens.
Regular Maintenance
To keep your filtration system working efficiently and your water tasting great, regular maintenance is essential. This includes cleaning and replacing your filters periodically.
Alternative Sources
If you're still not satisfied with your tap water’s taste after filtering, you might want to consider bottled or distilled water as an alternative. While bottled water can provide a more consistent taste, it’s important to choose brands that maintain high water quality standards. Distilled water, which has undergone a purification process to remove minerals and contaminants, offers a neutral taste but may lack essential minerals like calcium and magnesium.
The taste of water can be influenced by many factors, from mineral content to the materials used in its storage. While some variations in taste are normal, unusual flavours—like bitterness or a metallic taste—could be a sign of contamination. Invest in a right filtration system to ensure that your water tastes fresh, and clean.
FAQs
What factors influence water's taste?
Minerals, pH level, source of water, and storage materials (like pipes or plastic bottles) all affect the taste of water.
Why does my water taste bitter or metallic?
A bitter or metallic taste is often caused by dissolved metals like iron or copper from old pipes or high mineral content.
When should I get my water tested?
If your water consistently tastes odd or has an unusual odour or colour, it’s a good idea to have it tested for contaminants.
What is the standard taste of water?
Pure water is tasteless and odourless, but most water contains minerals that give it a mild taste depending on its source.
