What do you know about drinking water?
What makes water hard? How do we control the quality of water in Germany? With these and other questions about the food and drinking water the Forum is drinking water e. V. launched a representative survey on the Knowledge of German on your food number one. Most of the people in Germany can only answer one of three questions correctly – as the result of a representative survey by TNS Emnid, Institut for market and opinion research. Although many have knowledge about a good Part of that is a large information deficit.
Only a few know that Hard water contains a lot of Calcium and Magnesium
That “lime” for the hardness of the water is responsible, is the vast majority of people in Germany known. However, only every second person knows that lime from Magnesium and Calcium, and these two minerals hardness to the water are responsible. Almost every third person is of the view that iron is the cause of water hardness. Nearly one in four, with the response “lead” is completely wrong.
The lack of Knowledge is probably the reason why 40 per cent of the respondents of hard water, to ascribe a negative and most of the soft water has a positive effect on health. Also numerous requests on the Forum of drinking water e. V., whether the enjoyment of hard tap water is harmful to health, and led to a calcification of the arteries, to confirm the results of the survey. The answer is: no, because Calcium and Magnesium – constituents of lime are important mineral vital substances, which serve, for example, the structure of bones and teeth and for energy metabolism are essential.
However, studies show that in Germany the usual eating habits of both drinking water as well as mineral waters only to a limited extent to meet the mineral needs. Food such as milk and milk products, whole-grain bread, bananas, or vegetables are the more important sources.
Hard or soft water – a matter of taste
If the degree of hardness of the tap water drinks have an impact on the taste of Hot and cold, there’s disagreement among the respondents. Almost every Second of that hard water has, in its view, have a negative impact on the taste of coffee or tea. In the case of cold drinks that says only one in three. Each 33 percent of the respondents believe, however, that the degree of hardness have no influence on the taste.
In fact, coffee or tea develop their full flavor better if you are prepared with soft water. For cold drinks it is the opposite: Here, separate with a professional tasting in blind taste tests, water with a higher mineral content is often better than “soft”.
Drinking water: origin and quality control
The question of the origin of the drinking water in the largest part of the population answered correctly. It is 64 percent comes from a variety of resources – from groundwater, 27 percent from surface – and nine percent of the source water. All three origin types are called in.
The quality of drinking water is subject to nationwide with the strict regulations of the drinking water Ordinance for compliance with only the water supply companies and the health authorities. 89 percent know that the control of drinking water quality is the responsibility of the water supply companies, and 70 percent of the health departments as a quality Keeper. However, 40 percent of respondents are convinced that the consumer is Central for the control of drinking water quality. Overall, this question is answered by only 43 percent correct.
Hardly anyone knows it: A Liter of drinking water costs 0.2 cents
When it comes to the price, many are at a loss. Most of the answers to the question, “What is a Liter of drinking water costs, on average?” with “I don’t know”. For almost half of the population, it ranges between 0.7 to 50 cents. Not even 25 per cent of the respondents, with approximately 0.2 cents per litre for the right price. By the way, men have the better price, feeling: Every third man, but only just, every sixth woman is this question correctly.
No Knowledge Champions
While the majority of people in Germany are familiar with the origin and quality control of drinking water is quite good, there are considerable gaps in information, for example when it comes to the effects of water hardness on the health or the taste. As a correct knowledge Champions can refer to only seven percent of all German, one in four even has to fit in all the questions.
