Asda
Asda’s own-brand still natural mineral water. The 2 L product page says only “Sourced in Staffordshire, Packed in the U.K.”, with no spring or bottler named. A reseller says Elmhurst Spring (Lichfield, on Defra’s register); Asda doesn’t confirm it. Tesco prints a different analysis for the Elmhurst source, so we don’t assume the same spring.
