Nitrate, lime, rust – what’s in tap water?
In 2017, some irritation arose after it became known that the nitrate pollution of groundwater is beyond the limits. And even if it has a negative impact on the environment, it has no direct impact on the water quality of our drinking water. But it’s the waterworks that have to work harder to keep the water quality at the same level. This means that while we do not consume nitrate, this development could lead to drinking water from the tap becoming more expensive in the future in order to lower nitrate levels. But even then, the water from the faucet – in some regions almost affectionately called ‘Kranenberger’ – will probably always remain cheaper than bottled water.
Rust, or rather water with a high iron content, colors the water reddish and creates an unpleasant, metallic taste. However, even this has no harmful effects on the body. If the water from the tap is reddish, you should still let it run until it becomes clear again.
And then there is the lime content in the water. Lime in the water is completely harmless to humans. In fact, the calcium in the lime is even valuable to our health. However, increased lime content in the water causes problems for our kitchen and washing appliances. Here, the lime deposits on heating coils can lead to increased power consumption or even damage to the device. It is therefore important to descale coffee maker, washing machine and Co. regularly. Your water supplier will be pleased to give you any information about the limescale content in your drinking water and to make recommendations on how often it is advisable to decalcify the appliance.
