The quality of drinking water is a critical factor in ensuring both safety and taste. But did you know that the behavior of cold tap water changes depending on the season? In particular, cold water tends to „age“ faster in the summer than in the winter, and this phenomenon has to do with several environmental and physical factors that influence water quality.
Temperature Fluctuations and Their Impact
The primary difference between summer and winter is temperature. As temperatures rise during the summer months, the temperature of the water in pipes also increases. This subtle change can accelerate certain chemical and biological processes, such as the growth of microorganisms. Even though tap water is treated to meet safety standards, warmer temperatures can cause microorganisms to proliferate more quickly.
Microbial Growth and Water Composition
Water, particularly in warm conditions, provides an ideal environment for bacteria and other microorganisms to thrive. This is why water in pipes during the summer months can sometimes have a different taste or smell when left stagnant for a while. While the water from the tap might still meet safety regulations, the increased microbial activity can cause changes that aren’t always pleasant to the senses.
Stagnation and Water Quality
Another factor contributing to this „aging“ process is stagnation. Water that sits idle in pipes, especially during longer periods of non-use, becomes more susceptible to changes in composition. In the summer, these stagnant areas in plumbing systems are warmer, which can accelerate microbial and chemical reactions that affect the water’s freshness.
The Effect on Taste
The slow degradation of water quality, particularly from chemical reactions like oxidation, can alter its taste. While the water itself is still safe to drink, the interaction of the water with the pipes and other materials in the plumbing system can cause a noticeable shift in its flavor. This is why you might notice that the water tastes different after a few hours of sitting in the pipes during the hotter months.
Why This Happens More in Summer
When it comes to the physical properties of cold water, they change significantly in higher temperatures. Water becomes less capable of holding gases, like oxygen, when temperatures rise. This shift leads to a higher concentration of dissolved minerals and salts in the water. These concentration changes are conducive to the formation of deposits, as well as the growth of microorganisms [European Environmental Agency, https://www.eea.europa.eu/en/european-zero-pollution-dashboards/indicators/risk-of-chemical-mixtures-in-humans].
How to Prevent Aging in Summer
- Regular Use: Try not to leave water stagnant in pipes for extended periods. The more often water flows, the less likely it is to degrade.
- Advanced Filtration: Using high-quality filtration systems, such as Klar2O filters, can help maintain fresh-tasting water even during the summer months.
- Flush the Pipes: If you haven’t used your taps for a while, it’s good practice to let the water run for a minute or two before using it. This helps clear any stagnant water from the pipes and improves the taste.
The Bottom Line
Water aging in the summer is a natural process that can be influenced by temperature fluctuations, stagnation, and microbial activity. While it doesn’t mean that your water is unsafe to drink, it can affect its taste and freshness. By understanding these dynamics and using the right filtration systems, you can ensure that your water remains fresh and high-quality throughout the year.
