The resulting water is purified but still contains some dissolved solids. Natural water comes from unprotected well or spring systems and is bottled without extensive treatment. This water typically is free of the trace chemical additives found in many public water supplies. However, it contains most of the mineral contaminants commonly picked up by water as it moves through the air, soil, and rock materials. Because this is almost exclusively groundwater, it usually contains a range of minerals and is, therefore, quite flavorful.
Spring water rises naturally to the surface from underground.
Artesian water also rises under its own pressure, but only after it has been reached by drilling. Mineral water is from a natural spring or underground source. The mineral content is not modified by the manufacturer and can contain some dissolved solids. It can be still or sparkling. The carbon dioxide that causes carbonation is natural or added during bottling.
