Heavy Metals in Drinking Water?

Heavy metals such as lead, nickel, or copper can be present in drinking water. In small amounts, they pose no risk to health. However, exceedances of legal limits are not uncommon, even in Central Europe. In older buildings, outdated plumbing may release toxic substances into household water.

Lead in particular can cause serious health problems, especially for infants and young children—but also for adults. To protect yourself from heavy metals and other unwanted substances, certain precautions are necessary.

Which Heavy Metals Are Found in Drinking Water?

Lead, iron, nickel, and zinc are often found in European water systems. In older buildings, copper is also a common contaminant. Health risks usually occur only at excessive levels. While trace amounts of iron are essential, regular intake of higher doses can have severe consequences.

The human body can only process and eliminate these metals in limited quantities. If limits are exceeded, they accumulate in the organs, bones, or teeth.

What Health Issues Can Arise?

The accumulation of heavy metals in the body can lead to serious health issues. Lead, for example, is toxic to internal organs and especially affects the liver and kidneys. Common symptoms of heavy metal poisoning include nausea, vomiting, dizziness, and irregular heartbeat.

Some of these substances are classified as carcinogenic and may cause liver damage, particularly in children.

Where Do These Contaminants Come From?

Drinking water in Switzerland is strictly regulated and regularly tested for compliance with legal limits. However, these limits are relatively high in Europe, and violations have been reported.

A key issue is that quality control stops at the building connection. Inside older buildings, copper or even lead pipes may still be in use, leading to contamination from within the house.

How Can You Protect Yourself?

The first step is always to conduct a water test if you suspect contamination. This provides a clear overview of the water quality. In older buildings, replacing outdated pipes may be necessary.

Another effective option is the installation of a water filter. Placed between the faucet and the water source, it removes many unwanted substances before they reach your glass.

Conclusion

Lead, copper, nickel, and other heavy metals in drinking water can pose serious health risks—especially in buildings with outdated plumbing. If you suspect poor water quality, take action immediately. Start with a water test to assess the situation.

Based on the results, targeted solutions such as pipe replacement or water filtration can ensure your household enjoys safe, clean drinking water long term.
