Recent laws (D.Lgs 339/1999 and 31/2001) have allowed the bottling and sale of spring water and of table water provided they are not defined as "mineral", "natural" or "mineralized", but without characteristics that constitute a danger to human health. Like mineral water spring water mustn't be purified; is bottled as it gushes out from the source and is subject to the same requisites as tap water (DPR 236/1988). Table water is bottled purified water subject to the same requisites as tap water, whatever its original characteristics, during the process of purification, it can be modified to render it ideal for the needs of the consumer.
