Soda maker in the Trend: How is the quality of our tap water?
More and more people make their carbonated mineral water with so-called soda ago heaters. However, clear water is always clean?
Without the liquid of the human being can only survive for a few days. The healthiest drink for the body is water. Drinking water is from a river, lake, source or ground water can be obtained.
Before it is for the public network is available, it goes through several cleaning steps. The water that comes out of our pipelines, is subject to the strict regulations of the German water regulation – in Germany, it is probably the most strictly controlled food products.
Through our lines of health runs so good free water, but can pipes this through metals such as copper and lead from the water or with pollutants such as nitrate from soils to be impacted.
How clean is our tap water?
About half of all drinking water pipes in Germany, are made of copper. Although copper is an essential trace element, of the adult daily around 1 to 1.5 mg should. The water has an acidic pH-value below 7, it can be dissolved the copper from the pipes and in the water to accumulate.
Until the seventies of water were installed on pipes made of lead. In larger amounts, lead is toxic, especially for children. Soft water in combination with such tubes can lead to high lead concentrations in the tap water, which may damage to your health.
Nitrate and nitrite are components of fertilizers. Depending on the oxygen content of the water, they are converted into each other. Nitrate dissolves well in water and may therefore be due to leaching of the soil with the rain into the ground water. In areas with strong agriculture or intensive wine cultivation is operated can be increased, the values for nitrate. The limit value for nitrate under the drinking water regulation at 50 mg/l.
Drinking water contributes to about 25% of our nitrate intake, of vegetables to 60 %. Studies have shown in the last few years that the tap water is contaminated in many regions with uranium. A legally binding limit value does not exist so far, and will – if it is set – probably about the for small children a critical value. The non-binding conductance of the authorities is of 10 micrograms of uranium per Liter of water. Families with small children should use, therefore, possibly mineral water from bottles for the food production – to high uranium values are characterized by “not suitable for the preparation of infant food”.
