Among the mineral waters available in the USA in the h2oMatch database, these have the lowest fixed residue values.
Ultra-light mineral waters, those with very low fixed residue, are prized for their clean, neutral taste and smooth drinking experience. In the US market, the lightest options are all European imports, primarily from Italian alpine springs.

For Americans accustomed to purified or filtered water, these ultra-light European mineral waters offer a similar clean taste profile while being entirely natural and untreated, sourced from protected mountain springs where the geology naturally produces minimally mineralized water.
A note on definitions: h2oMatch lists natural mineral waters in the European legal sense, officially recognised waters with a stable mineral composition. The US FDA defines 'mineral water' differently, requiring at least 250 ppm of total dissolved solids. European natural mineral waters have no minimum, which is why very light waters appear in this ranking. The threshold figures cited on this page are EU label criteria, not US regulations.

FAQ
What is the lightest mineral water available in the USA?
Sant'Anna, with a fixed residue of 22 mg/L, is the lightest natural mineral water in the h2oMatch US database, followed by Lurisia (35 mg/L) and VOSS (40 mg/L).
What does 'very low mineral content' mean?
It is a European Union labeling category for natural mineral waters whose fixed residue does not exceed 50 mg/L. Waters with up to 500 mg/L are categorized as having 'low mineral content'.
How can a 22 mg/L water be called a 'mineral water' in the US?
The term 'natural mineral water' on these imported products follows the European definition, which has no minimum mineral content. The US FDA has a different definition for 'mineral water', requiring at least 250 ppm of total dissolved solids.
Why are there almost no American natural mineral waters?
The European status simply does not exist in US law, American bottled waters are classified by FDA categories such as spring, purified or mineral water instead. Most popular US brands are spring or purified waters, which is why the recognised natural mineral waters sold in America are overwhelmingly European imports.
What is light water best suited for?
Its neutral, soft taste makes it a favourite for tea and coffee, where it lets the aromas through and leaves minimal scale on heating. It is also the everyday choice of people who simply prefer water with no mineral edge.
