Polluted drinking water - where is there a risk?

Polluted drinking water can mean a huge health risk. Bacteria, pathogens, harmful chemical substances and high pollution levels make drinking contaminated water a risk. Where there is a risk of encountering polluted drinking water and what is best done against it is explained here.

Drink from unknown sources

Even if a mountain spring looks very clear and clean at first glance, it can contain dangerous germs or pollutants. Water that is not verified is fundamentally untrustworthy. One should always think about hiking and trekking.

On-the-go water filters, for example from Katadyn, help to efficiently clean dirty drinking water. Their filter pores are so small that even bacteria and protozoa are filtered out.

Even more practical is the LifeStraw, which has an equally good filtering effect, but even allows direct drinking from a polluted source. Regarding the quality, however, the individual products offered differ again and again.

To Sterilize water quickly, SteriPen is best suited. It can be operated with batteries on the go, and performs a very reliable UV disinfection of water in no time. However, other potential pollutants in the water are not removed and are not inactivated.

The SODIS process can also be used to sterilize water on the way. However, it is - depending on the position of the sun - quite time consuming.

Southern countries and third world countries

In many southern countries, drinking water requirements are far less stringent than in Germany. Often, the networks are damaged.

In many developing and emerging countries, there is often no really clean drinking water available. Even bottled water you can not always fully trust.

When traveling, a portable water filter is therefore enormously helpful. Even heavily contaminated water can thus be reliably cleaned. An additional sterilization with the SteriPen also kills possibly existing viruses, which pass through their small size water filters.

Alleged contaminated drinking water

The claim that German drinking water is also burdened with many dangerous substances earns a lot of money.

Expensive water treatment equipment, water filters, reverse osmosis systems and chemically completely unnatural changed water such as base water are offered because the German drinking water is allegedly not reliable and heavily polluted.

However, current tests of tap water quality can never prove this. It is a pure marketing argument of the manufacturers, who of course want to sell their devices in large numbers.

The same argument also leads to sales of more than 10 billion liters of bottled water per year in Germany, which has a catastrophic LCA and CO balance. This is mostly water, which corresponds to the quality of tap water 1: 1 or even lower quality.

Tips & Tricks

If you really do not trust your tap water, have a water analysis done in a lab before buying an expensive device you do not need.
