Can switching from tap water to natural source water lead to a magnesium deficiency?
No. Water is not a significant source of magnesium, therefore switching from tap water to natural source waters or vice versa will not have a significant impact on your magnesium levels.
Can natural source waters be traced?
Yes. It is a legal requirement in the EU and UK for each batch of natural source waters to be traceable, like any other food product. For every batch it is possible to trace the specific results for quality and the safety controls that were carried out during and after production.
Where do I find the legislation regulating natural mineral water and spring water?
Framework legislation includes:
Natural Mineral Water and Spring Water: Directive 2009/54/EC of the European Parliament and of the Council on the exploitation and marketing of natural mineral waters, sets the requirements for the exploitation and marketing of natural mineral waters and spring waters. This specifies their safety requirements and mandatory controls.
In the UK, this is also covered by The Natural Mineral Water, Spring Water and Bottled Drinking Water Regulations 2007.
Where do I find the legislation regulating tap water?
The Drinking Water Directive (DWD), Council Directive 98/83/EC, sets quality standards for drinking water quality at the tap (microbiological, chemical and organoleptic parameters) and the general obligation that drinking water must be wholesome and clean.
What is municipal water?
Municipal water is the chemically treated water which can come from a variety of sources that you get out of your tap. It can also be used on a larger scale for manufacturing, construction and other industrial purposes.
What is functional water?
Functional waters can originally be either a natural source or tap water but then they have something added to adjust the pH or minerality of the water. These changes can then be marketed as beneficial.
What is modified water?
Modified water can originally be either a natural source or tap water but then they undergo a process, such as distillation, to add or remove elements in the water in order to adjust the pH or minerality. These changes can then be marketed as beneficial.
