StillStaffordshireNatural mineral water

Asda Still Natural Mineral Water is sourced from a spring near Lichfield, Staffordshire. It is the own-brand still water of Asda (owned by Walmart). The same Staffordshire source is shared with Tesco Elmhurst and the UK variant of Lidl Saskia, all of which produce near-identical mineral profiles. Bottling is handled by a contracted bottler in the region. Asda holds natural mineral water status.

Asda’s mineral profile is identical, or near-identical, to Tesco Elmhurst and Lidl Saskia UK: bicarbonate 166 mg/L, calcium 40 mg/L, magnesium 14 mg/L, sodium 6 mg/L, sulphate 10 mg/L, and chloride 11 mg/L. Total hardness is 158 mg/L as CaCO₃; alkalinity is 136 mg/L as CaCO₃. TDS is approximately 228 mg/L. The profile is soft to medium-soft, balanced, and unremarkable: no single ion stands out, and the chloride-to-sulphate ratio of roughly 1:1 sits in the middle of the spectrum.
