Heavy Metals in Drinking Water?

Heavy metals such as lead, nickel, or copper are components of our drinking water. In small quantities, they do not have any health effects. However, in many cases, there are exceedances of the applicable limits even in Central Europe. In older buildings, due to old water pipes, toxic substances can be added to the water within the house. Lead in drinking water can lead to concerning health issues, especially for infants and young children, but also for adults. To protect yourself from heavy metals and other unwanted substances, there are certain points to be aware of.

Which Heavy Metals Are Found in Drinking Water?

Lead, iron, nickel, and zinc are often found in European water pipes. In older buildings, copper is also a common byproduct of drinking water. Health risks only arise with excessive doses. Iron, in small amounts, is an important trace element. However, if these substances are consumed in large quantities daily, it can have devastating consequences. The human body can only process and eliminate these substances in certain dosages. If limits are exceeded, lead, nickel, or copper remain in the body and accumulate in organs, bones, or teeth.

What Health Issues Can Arise?

These accumulations result in concerning health risks. Lead in drinking water, when absorbed by the body in large amounts, can be toxic to organs, particularly affecting the liver and kidneys. Common symptoms of heavy metal poisoning include nausea, vomiting, dizziness, and even heart arrhythmias. Some of these toxic substances are proven to be carcinogenic and often cause liver damage in young children.

Where Do Harmful Substances in Drinking Water Come From?

In principle, drinking water in Switzerland is highly regulated, and there are strict checks on compliance with the limits. Nevertheless, these values are set high in Europe, and there have been several cases of exceedances. Another important point is that water quality is only checked up to the house connection. In older buildings, old water pipes, primarily made of copper, are often installed. Lead can also accumulate in drinking water, often in the form of deposits.

How Can You Protect Yourself?

The first step if you suspect toxic substances like lead in your drinking water is always to conduct a water test. This will give an indication of water quality and whether it may be concerning. In older buildings, it may also be advisable to replace old water pipes with new ones. Another very advisable solution is the use of a water filter. This is placed between the faucet and the house connection and filters unwanted substances out of the drinking water.

Especially in older buildings with old water pipes, there is often an unwanted burden of heavy metals. If you suspect poor water quality, it is essential to take immediate action, starting with a water test.
