Spring water is derived from an underground formation from which water flows to the Earth's surface. While spring waters are treated to remove bacteria and possible contaminants, most spring waters retain many of the Total Dissolved Solids (TDS), trace compounds and other substances found in the water.
Purified water is sourced from water systems that provide safe drinking water and are regulated by the Environmental Protection Agency (EPA). This water is then taken through purification systems designed to remove substances according to Food and Drug Administration (FDA) standards. The purification system used by Aquafina employs standards that are even more stringent that those set by the FDA. Aquafina delivers pure water with perfect taste. Every time.
More info on Total Dissolved Solids (TDS):
TDS is the sum of all solids dissolved in water measured in parts per million (ppm) Examples of substances that can account for TDS include carbonates, bicarbonates, chlorides, sulfates, phosphates, nitrates, calcium, magnesium, sodium, potassium, iron, manganese, and a few others.
A TDS meter is used to provide a reading of the dissolved solids in water. FDA guidelines require that bottled water, excluding mineral water, contain no more than 500 ppm TDS. For a bottled water to be labeled "purified," it must have TDS of no more than 10 ppm.
Aquafina's average TDS reading is 4 — that's 2.5 times lower than FDA standards and 75% less than the closest competitive brand.
