s. Today, it is far more common for mineral water to be bottled at the source for distributed consumption. Travelling to the mineral water site for direct access to the water is now uncommon, and in many cases not possible because of exclusive commercial ownership rights. More than 4,000 brands of mineral water are commercially available worldwide. In many places the term "mineral water" is colloquially used to mean any bottled

found slightly reduced cardiovascular disease mortality from consuming harder water with higher mineral amounts, with magnesium and possibly calcium being the most likely contributors. However, mineral amounts vary greatly among different brands of mineral water, and tap water can contain similar or greater amounts of minerals. One study found that the median mineral content of North American mineral waters was lower than for tap water, though values varied widely among both groups. Additionally, other dietary sources of minerals are available and may be more cost effective and less environmentally impactful than bottled mineral water.
