Drinking water filters - for travel to which countries do they make sense?

The drinking water quality in Germany is still so high that an additional filtering of the tap water can be omitted, with a few exceptions. But in other countries, that can be different throughout. Wherever you should equip with a drinking water filter as a precaution, you can read here.

Drinking water quality in Europe

UNESCO has tested drinking water quality in 122 countries worldwide. The result of the "World Water Development Report" was quite surprising.

Within the EU, the worst quality of water is surprisingly found in Belgium - a country that is known throughout the world for its mineral springs and baths. The reason for this is not only the high pollution of the groundwater by the industry, but also a very poor wastewater treatment. In a global comparison, Belgium is even behind India and some African countries.

Germany also does not fare well in the quality test of water, but there are no grounds for concern. The test focused on the cleanliness of rivers and groundwater in the country and the measures taken and planned by the respective countries to improve the water quality.

Given the EU-wide Drinking Water Directive, which requires the same strict controls on drinking water for all European countries and the corrective measures before they are routed through the pipelines, in most cases there is little need to worry about them in EU countries.

However, caution is still required in southern countries. Here, for cost reasons, water pipes are often laid very close to the surface. As a result, the temperature of the cold water pipes rises to very high levels, especially in summer. Bacteria and germs thus find ideal conditions in the otherwise unaffected cold water lines to multiply. High germ counts are therefore often unavoidable with tap water. Here, as a precaution, filtering the water is recommended.

Drinking water quality in countries outside Europe

The causes of poor tap water quality are manifold:

  • Marode pipe systems
  • insufficient sewage treatment and thus pollution of the groundwater
  • Pollution of groundwater by residues from industry and agriculture

For example, frequently visited holiday destinations, such as Martinique, also pose a high risk: Farmers use a high amount of pesticides, which pollute the groundwater. These pesticides are then found in tap water again.

Emerging and developing countries are already notorious for their poor water quality. In many African and Asian countries, the pollution of drinking water is also the cause of countless illnesses and deaths.

Bottles of water quality

In many countries, the quality of bottled water is doubtful, even if it is bottled industrially. This is especially true of poorer emerging economies, where industry standards are very low. Here bottled water can also be contaminated with germs. So it is better to safely and reliably rid the water of all pollutants and germs for drinking, cooking and brushing your teeth with portable water filters.
